Answer: 20 pounds.

Step-by-step explanation:

We know the weight of each flower arrangement (each one weighs 6 2/3 pounds) and the total number of flower arrangaments Isabelle ordered (3 flower arrangements).

To make the calculus easier, we can rewrite the mixed number 6 2/3 as a decimal number:

Divide the numerator 2 by the denominator 3 and add the result to the whole number 6:

[tex](6+0.666)lb=6.666lb[/tex]

If 1 arrangement weighs 6.666 pounds, the total weigth of 3 arrangements can be calculated by multiplying 6.666 pounds by 3:

[tex]weight_{(total)}=(6.666lb)(3)\\weight_{(total)}=20lb[/tex]

[tex]\text{The general form of an ellipse is:}\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1\\\\\bullet \text{(h, k) is the Center}\\\bullet \text{a is the radius of x}\\\bullet \text{b is the radius of y}\\\bullet \text{the largest value between a and b is the major}\\\bullet \text{the smallest value between a and b is the minor}\\\bullet \text{the vertices are the (h, k) value plus the major (a or b) value}\\\bullet \text{the co-vertices are the (h, k) value plus the minor (a or b) value}\\\bullet \text{Length is the diameter}=2r\\[/tex]

[tex]\dfrac{x^2}{16}+\dfrac{y^2}{25}=1\quad \text{can be rewritten as}\ \dfrac{(x-0)^2}{4^2}+\dfrac{(y-0)^2}{5^2}=1\\\\\bullet (h, k)=(0,0)\\\bullet a=4\\\bullet b=5\\\bullet \text{b is the largest value so: b is the major and a is the minor}\\\bullet \text{Vertices are }(0, 0+5)\ and\ (0, 0-5)\implies (0, 5)\ and\ (0, -5)\\\bullet \text{Co-vertices are }(0+4, 0)\ and\ (0-4, 0)\implies (4,0)\ and\ (-4,0)\\\bullet \text{Length of major is }2b:2(5)=10\\\bullet \text{Length of minor is }2a:2(4)=8[/tex]

To find the foci, first we must find the length of the foci using the formula:

Answer:

79.5688 < µ < 83.1646

Step-by-step explanation:

Sample mean is the sum of all scores, divided the the total number of test takers.  In this case, the sample mean is:

(87.4 + 86.9 + 89.9 + 78.3 + 75.1 + 70.6)/6 =  488.2/2 = 81.3667

The sample standard deviation is the square root of the sample variance.  See attached photo 1 for calculation of these values...

The sample standard deviation is 3.1856

We need to make a 90% confidence interval for this data.  Since n < 30, we will use a t-value.  The degrees of freedom is always one less than the sample size so on the t-distribution chart, look under the column for Area under the curve = 0.10, and the row for 5.  The t-value you should see is t = 2.015

Answer: The answers are

(1) 90 cm²   and (2) 321 m³.

Step-by-step explanation:  The calculations are as follows:

(1) The triangles ABC and PQR are similar. And the area of ΔABC is 40 cm².

Also, AB = 4 cm  and PQ = 6 cm.

We are to find the area of triangle PQR.

Similarity ratio of two similar triangles is equal to the ratio of any two corresponding sides of the triangles.

So, the similarity ratio of ΔABC and ΔPQR is given by

[tex]\dfrac{AB}{PQ}=\dfrac{4}{6}=\dfrac{2}{3} =2:3\\\\\\\Rightarrow AB:PQ=2:3.[/tex]

Now, let the area of ΔPQR be denoted by [tex]A_{PQR}.[/tex]

We know that the ratios of the area of two similar triangles is equal to the ratios of the squares of any two corresponding sides of the triangles.

Therefore, we must have

[tex]\dfrac{\textup{area of triangle ABC}}{\textup{area of triangle PQR}}=\dfrac{AB^2}{PQ^2}\\\\\\\Rightarrow \dfrac{40}{A_{PQR}}=\left(\dfrac{AB}{PQ}\right)^2\\\\\\\Rightarrow \dfrac{40}{A_{PQR}}=\left(\dfrac{2}{3}\right)^2\\\\\\\Rightarrow \dfrac{40}{A_{PQR}}=\dfrac{4}{9}\\\\\\\Rightarrow 4\times A_{PQR}=40\times 9\\\\\\\Rightarrow A_{PQR}=90~\textup{cm}^2.[/tex]

Thus, the area of triangle PQR is 90 cm².

(2) Given that a science museum has a spherical model of the earth with a diameter of 8.5 m.

We are to find the volume of the model.

Since the model is spherical in shape, so will be using the following formula:

the volume of a sphere with radius 'r' units is given by

[tex]V=\dfrac{4}{3}\pi r^3.[/tex]

The diameter of the model is 8.5 cm, so the radius of the model will be

[tex]r=\dfrac{8.5}{2}=4.25~\textup{m}.[/tex]

Therefore, the volume of the model is given by

[tex]V\\\\\\=\dfrac{4}{3}\pi r^3\\\\\\=\dfrac{4}{3}\times3.14\times(4.25)^3\\\\\\=\dfrac{964.17625}{3}\\\\\\=321.39\sim 321~\textup{m}^3.[/tex]

Thus, the volume of the model is 321 m³.

Hence, the answers are

(1) 90 cm²   and (2) 321 m³.

Answer:

The correct answers are as follows.

a. 8.624%

b. 60.84%

c. 27.75%

Step-by-step explanation:

In order to find each of these, take the likelihood of each of steps and multiply them together.

a. For this one, we need to note that the first two spins should not be blue. The likelihood of them not being blue is the chance for red and green put together (37%). Then we want the third spin to be the blue odds (63%)

.37 * .37 * .63 = .08624 = 8.624%

b. For the purpose of this, we are looking just for the first two spins to not be red (78% probability). After that, it does not matter what the third spin is since it says "at least 3 times)

.78 * .78 = .6084 = 60.84%

c. For this one, we need to combine two things. Firstly, the chance that the first spin is green (15%). Then we would add in the likelihood that the first spin is not green (85%), but the second is.

.15 + (.85 * .15) = .2775 = 27.75%

The probabilities of obtaining the required event based on the likelihood of the pointer stopping on each color are 0.086247, 0.6084 and 0.2775 respectively

Probability of Blue ; P(B) = 0.63

Probability of Red ; P(R) = 0.22

Probability of Green ; P(G) = 0.15

Probability of Blue after exactly 3 spins :

1st spin = P(not B) = P(R)+P(G) = (0.22+0.15) = 0.37

2nd spin = P(not B) = P(R)+P(G) = (0.22+0.15) = 0.37

3rd spin = P(B) = 0.63

P(R exactly after 3 spins) = (0.37 × 0.37 × 0.63) = 0.086247

2.)

Probability of spinning atleast 3 times before obtaining RED;

P(not R) on first two spins ;

P(not R) = P(B) + P(G) (0.63+0.15) = 0.78

P(not R) × P(not R) = 0.78 × 0.78 = 0.6084

3.)

Probability of obtaining Green after 2 or fewer spins :

P(Green after 2 spins) + P(Green on first spin)

P(not G) = 0.63 + 0.22 = 0.85

[P(not G) × P(G)] + P(G)

[(0.85 × 0.15) + 0.15]

(0.1275 + 0.15)

= 0.2775

Answer:

Hyperbola

Step-by-step explanation:

Given is an equation in x and y as

[tex]xy = -16[/tex]

We know that for ellipse both x and y will have degree 2.

For parabola one variable would be of degree 2 and other degree 1.

Circle both will have degree 2 and equal coefficients.

So this equation is not a circle, a parabola or an ellipse.

We know that rectangular hyperbola will have equation as

[tex]xy=c^2 \\xy =-c^2[/tex]

Hyperbola is the right answer.

Answer:

Option b

Step-by-step explanation:

By definition we know that:

[tex]cos ^ 2(\theta) = 1- sin ^ 2(\theta)[/tex]

We know that for this case:

[tex]sin(\theta) = \frac{1}{4}[/tex]

Then:

[tex]cos ^ 2(\theta) = 1- (\frac{1}{4})^2\\\\cos ^ 2(\theta) = 1- (\frac{1}{16})\\\\cos ^ 2(\theta) = \frac{15}{16}\\\\[/tex]

Apply square root on both sides of the equation

[tex]\sqrt{cos ^ 2(\theta)} = \sqrt{\frac{15}{16}}\\\\cos(\theta) = \sqrt{\frac{15}{16}}\\\\cos(\theta) = \frac{\sqrt{15}}{4}[/tex]

The most appropriate measure of center is Median. As the data has a large value (290) at the end, it is the better choice to choose the median for finding the center because the mean or average is appropriate to represent the general level if there are not too large or too small values in the set. The median for the given bowling scores for 6 people is 117.5.

Since the standard deviation and range gives the variability of the given data, the mean and median are used for calculating the center.

Given data values are,

112, 114, 115, 120, 122, 290

Mean of the given data values,

Mean = Sum of all values / number of values

Sum of values = 112 + 114 + 115 + 120 + 122 + 290 = 873

Number of values = 6

∴ Mean = [tex]\frac{873}{6}[/tex]

             = 145.5

Median of the given data values,

Arranging the data values in the ascending order - 112, 114, 115, 120, 122, 290

Number of values = 6 (even)

So, the median is the average between the two centers

∴ Median = [tex]\frac{115+120}{2}[/tex]

                = 117.5

Since the last value in the set is larger than all the values (a sudden change or rise in the value), the most appropriate measure of center is the median and it is 117.5.

Answer:

A) 0.123; B) 0.8078; C) Because the population is normally distributed.

Step-by-step explanation:

For part A,

We first calculate the z-score, which tells us how many standard deviations from the mean our score is.

Since we are finding the z-score of an individual score and not a sample, we use the formula

[tex]z=\frac{X-\mu}{\sigma}[/tex]

Our score, X, is 209.3; our mean, μ, is 200; and our standard deviation, σ, is σ.  This gives us

[tex]z=\frac{209.3-200}{8}=\frac{9.3}{8}=1.1625[/tex]

We look this value up in a z-table.  However, we must round it to the nearest hundredth first; this is 1.16.  From a z-table, we get that the area under the curve to the left of, or less than or equal to, this score is 0.8770.

However we want the probability that the value is greater than this; this means we subtract our found probability from 1:

1-0.8770 = 0.123

For part B,

Again we first calculate the z-score.  However this time we are finding the probability of a mean of a sample rather than an individual score; this means we use the formula

[tex]z=\frac{\bar{X}-\mu}{\sigma\div \sqrt{n}}[/tex]

Our X is 198.20; our μ is still 200, and our σ is still 8; our value of n is our sample size, 15:

[tex]z=\frac{198.20-200}{8\div \sqrt{15}}=\frac{-1.8}{2.0656}=-0.87[/tex]

Looking up this value in a z-table, we get 0.1922.

However, we want the probability that the area, or probability, is greater than this; so we subtract from 1:

1-0.1922 = 0.8078

For part C,

When a population is normally distributed, this means that a sample taken from this population will also be normal; this means we can use the normal distribution.

Answer:

The answer is hyperbola; with angle of rotation = 45° ⇒ answer (b)

Step-by-step explanation:

* At first lets talk about the general form of the conic equation

- Ax² + Bxy + Cy²  + Dx + Ey + F = 0

∵ B² - 4AC < 0 , if a conic exists, it will be either a circle or an ellipse.

∵ B² - 4AC = 0 , if a conic exists, it will be a parabola.

∵ B² - 4AC > 0 , if a conic exists, it will be a hyperbola.

* Now we will study our equation:

- xy = -2.5

∵ A = 0 , B = 1 , C = 0

∴ B² - 4 AC = (1)² - 4(0)(0) = 1 > 0

∴ B² - 4AC > 0

∴ The graph is hyperbola

* To find the angle of rotation use the rule:

- cot(2Ф) = (A - C)/B

∵ A = 0 , B = 1 , C = 0

∴ cot(2Ф) = 0/1 = 0

∴ 2Ф = 90°

∴ Ф = 45°

* The answer is hyperbola; with angle of rotation = 45°

IV. A linear correlation coefficient of 0.62 suggests a stronger linear relationship than a linear correlation coefficient of -0.82.

False.

So, the correct statements are I and III.

Therefore, the correct answer is:

OB. I and II

Let's evaluate each statement:

I. If the linear correlation coefficient for two variables is zero, then there is no relationship between the variables.

True. A correlation coefficient of zero indicates no linear relationship between the variables. However, it's important to note that there could still be a nonlinear relationship.

II. If the slope of the regression line is negative, then the linear correlation coefficient is negative.

False. The linear correlation coefficient (Pearson correlation coefficient) measures the strength and direction of a linear relationship between two variables. It ranges from -1 to 1. The sign of the correlation coefficient indicates the direction of the relationship (positive or negative), not the slope of the regression line. So, this statement is not necessarily true.

III. The value of the linear correlation coefficient always lies between -1 and 1.

True. The linear correlation coefficient, also known as Pearson's correlation coefficient, ranges from -1 to 1. A correlation coefficient of -1 indicates a perfect negative linear relationship, 0 indicates no linear relationship, and 1 indicates a perfect positive linear relationship.

IV. A linear correlation coefficient of 0.62 suggests a stronger linear relationship than a linear correlation coefficient of -0.82.

False. The magnitude (absolute value) of the correlation coefficient indicates the strength of the linear relationship, regardless of the sign. Therefore, a correlation coefficient of -0.82 suggests a stronger linear relationship compared to a correlation coefficient of 0.62.

So, the correct statements are I and III.

Therefore, the correct answer is:

OB. I and IV

The complete question is here:

Which of the following statements concerning the linear correlation coefficient are true? 1: If the linear correlation coefficient for two variables is zero, then there is no relationship between the variables. II: If the slope of the regression line is negative, then the linear correlation coefficient is negative. III: The value of the linear correlation coefficient always lies between - 1 and 1.

B. I and IV

C. I and II

D. II and III

The true statements for the given information are:

I: If the linear correlation coefficient for two variables is zero, then there is no relationship between the variables.

III: The value of the linear correlation coefficient always lies betweenminus1 and 1.

The correct options are I and III.

I: If the linear correlation coefficient for two variables is zero, then there is no relationship between the variables. This statement is true. The linear correlation coefficient, also known as Pearson's correlation coefficient (r), measures the strength and direction of the linear relationship between two variables. When r = 0, it indicates that there is no linear relationship between the variables.

II: If the slope of the regression line is negative, then the linear correlation coefficient is negative. This statement is not necessarily true. The slope of the regression line indicates the direction and steepness of the relationship between the variables, while the correlation coefficient indicates the strength and direction of the linear relationship. The correlation coefficient can be negative even if the slope of the regression line is positive, and vice versa.

III: The value of the linear correlation coefficient always lies between -1 and 1. This statement is true. The correlation coefficient ranges from -1 to 1, where -1 indicates a perfect negative linear relationship, 0 indicates no linear relationship, and 1 indicates a perfect positive linear relationship. Therefore, the correlation coefficient always falls within this range.

IV: A linear correlation coefficient of 0.62 suggests a stronger linear relationship than a linear correlation coefficient of -0.82. This statement is false. The magnitude of the correlation coefficient indicates the strength of the linear relationship, regardless of whether it is positive or negative. Therefore, in this case, the correlation coefficient of -0.82 suggests a stronger linear relationship compared to 0.62 because the magnitude of -0.82 is larger than that of 0.62.

In summary, statements I and III are true, while statements II and IV are false.

Which of the following statements concerning the linear correlation coefficient are true?

I: If the linear correlation coefficient for two variables is zero, then there is no relationship between the variables.

II: If the slope of the regression line is negative, then the linear correlation coefficient is negative. III: The value of the linear correlation coefficient always lies betweenminus1 and 1.

IV: A linear correlation coefficient of 0.62 suggests a stronger linear relationship than a linear correlation coefficient of minus 0.82.

There are no compound periods given, so use the simple interest formula:

A = P(1+rt) where P is the principal, r is the rate and t is the time.

A = 5000(1+0.0975(6))

A = 5000(1+0.585)

A = 5000(1.585)

A = $7,925

Interest = 7925 - 5000 = $2,925

Total paid back = $7,925

Answer:

The Interest is 2,925.00 and now you owe 7,925.00. I hope this helps
