Step-by-step explanation:

Answer:

x = 6º

Step-by-step explanation:

120º = 15(x +  2)

 120 = 15x + 30

  15x = 120 - 30

  15x = 90

      x = 90/15

      x = 6º

The measure of x is 6°, which corresponds to option B: x = 6, using the property of parallel lines.

We can observe that the given lines are parallel cut by a transversal.

So, the angles 120° and 15(x + 2) are alternate exterior angles which are equal.

So, 120° = 15(x + 2)

To find the value of x:

1. Start by isolating the variable x on one side of the equation.

  Subtract 30 from both sides to move the constant term to the other side:

  120° - 30° = 15(x + 2) - 30°

2. Simplify the equation:

  90° = 15(x + 2)

3. Now, divide both sides of the equation by 15 to solve for x:

  (90°) / 15 = (15(x + 2)) / 15

4. Calculate:

  90° / 15 = 6°

So, x = 6°.

Therefore, the correct answer is: B. x = 6.

Step-by-step explanation:

First, you want to get the equation to equal 0.

[tex]x^{2} - 36 = 5x[/tex] subtract 5x from both sides to make the equation equal to 0.

[tex]x^{2} -5x - 36 =0[/tex]

Now you are going to want to factor the equation

Find factors that add up to 5

[tex](x+4)(x-9)[/tex] I used 4 and 9 because they multiply to be 36, since 36 is negative that means that one of the numbers has to be negative. I made 9 negative because when you add 4 it equals 5.

Make both equations equal to 0

[tex]x+4=0[/tex]

   [tex]-4[/tex]  [tex]-4[/tex]   subtract 4 from both sides to get x alone

  [tex]x = -4[/tex]

[tex]x-9=0[/tex]

Answer:

CI(99%) = ( 0.93 , 2.07)

Therefore at 99% confidence interval (a,b) = ( 0.93 , 2.07)

Critical value z(at 99% confidence) = z(0.005) = 2.58

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

x+/-zr/√n

Given that;

Mean gain x = 1.5

Standard deviation r = 0.58

Number of samples n = 7

Confidence interval = 99%

Critical value z(at 99% confidence) = z((1-0.99)/2)

z(0.005) = 2.58

Substituting the values we have;

1.5+/-2.58(0.58/√7)

1.5+/-2.58(0.2192)

1.5+/-0.565536

1.5+/-0.57

= ( 0.93 , 2.07)

Therefore at 99% confidence interval (a,b) = ( 0.93 , 2.07)

Answer:

Step-by-step explanation:

Hello!

To study if the biomass of Gonyostomum semen can be controlled by grazing zooplankton species the research team examined the relationship between:

Y: Net grow rate of G. semen in a test tube.

X: Number of D. magna grazers introduced in test tubes.

Since they are testing the relationship between two variables, i.e. how one variable affects the other, the researchers made a linear regression analysis and estimated the slope of the regression:

The point estimate of the slope: b= -0.5286

Standard deviation of the slope: Sb= 0.1059

n= 6 test tubes.

a)

For the hypotheses:

H₀: β = 0

H₁: β ≠ 0

The formula for the t-statistic is:

b)

The statistic has n-2 degrees of freedom.

So in this case you are working with a Student's t with 6-2= 4 degrees of freedom.

c)

Considering a one-sided alternative hypothesis H₁: β > 0, the calculated value of the statistic under the null hypothesis doesn't change, what change is the direction and size of the rejection region. In item a, the hypotheses had a two-tailed rejection region, for this item the rejection region is one-tailed to the right. This means that you'll reject at hight values of the statistic. The p-value is also one-tailed and you'll find it in the right tail of the distribution (That's why it's positive):

P(t₄≥4.99)= 1 - P(t₄<4.99)

Looking at the t-table. For this distribution, the value of 4.99 is between the t values that accumulate P(t₄<4.604)= 0.995 and P(t₄<7.173)= 0.999 of probability, so it will be between:

1 - 0.995= 0.005

and

1 - 0.999= 0.001

Using the given table and considering the value is closer to 4.064 than 7.173, the p-value will be approximate:

0.00025 < P < 0.005

The p-value is less than the significance level, α: 0.05, so the decision is to reject the null hypothesis. You can conclude that the population slope is not negative (β > 0)

⇒There is not enough evidence to conclude that the population slope β is negative.

I hope you have a SUPER day!

The answers are: a) The t statistic is approximately -4.99. b)  the degrees of freedom are 4. c) There is strong evidence that the population slope β is negative.

(a) The t statistic for testing the null hypothesis H0: β = 0 is calculated using the formula:

t = (b - 0) / SEb

Where:

b = slope coefficient = -0.5286

SEb = standard error of the slope coefficient = 0.1059

Substitute the values into the formula:

t = (-0.5286 - 0) / 0.1059 ≈ -4.99

So, the t statistic is approximately -4.99.

(b) The degrees of freedom for the t statistic can be calculated using the formula:

df = n - 2

Where n is the number of data points, which is the number of observations (in this case, the number of Daphnia grazers), minus 2 for the two estimated coefficients (intercept and slope).

Given that there are 6 data points:

df = 6 - 2 = 4

So, the degrees of freedom are 4.

we see that the P-value falls between 0.001 and 0.0025. Therefore, we can approximate the P-value as:

0.001 < P < 0.0025

(c) Using α = 0.05 as the significance level, we compare the P-value to α. Since the P-value is less than α (0.0025 < 0.05), we reject the null hypothesis.

Therefore, the conclusion is: There is strong evidence that the population slope β is negative. In other words, based on the provided data and statistical analysis, it can be concluded that there is strong evidence that an increase in the number of Daphnia magna grazers is associated with a decrease in the net growth rate of Gonyostomum semen, indicating that the grazers are likely reducing the algal growth.

(b) A type I error occurs when we discard a true null hypothesis (H₀) and a type II error is made when we fail to discard a false null hypothesis (H₀).

(c) In this case, type II error has the more severe consequences.

Step-by-step explanation:

It is provided that a hotel installs smoke detectors with adjustable sensitivity in all public guest rooms.

(a)

The hypothesis can be defined as follows:

H₀: There is no fire.

Hₐ: There is a fire.

(b)

A type I error occurs when we discard a true null hypothesis (H₀) and a type II error is made when we fail to discard a false null hypothesis (H₀).

In this case a type I error will be committed if we conclude that there is a fire and the smoke detector sounds an alarm, when in fact there is no fire.

In this case a type II error will be committed if we conclude that there is no fire and the smoke detector does not sounds an alarm, when in fact there is a fire.

(c)

In this case, type II error has the more severe consequences.

Concluding that there is no fire as the smoke detector did not sound an alarm, when in fact there is a fire, will cause casualties and is harmful for the health of the guests.

Guests would not be alert about the fire as there was not any alarm, and many may loose their lives because of this.

The null hypothesis is 'There is no fire', the alternative hypothesis is 'There is a fire'. A Type I error would be sounding an alarm when there is no fire (rejecting the null hypothesis when it is true), a Type II error would be not sounding an alarm when there is a fire (failing to reject the null hypothesis when it is false). The more severe consequence would be due to a Type II error, as it could result in unrecognized danger.

In this scenario, the null hypothesis would be 'There is no fire' and the alternative hypothesis would be 'There is a fire'. In terms of type I and II errors, a Type I error would occur if the smoke detector sounded an alarm when there is no fire, or in other words, rejecting the null hypothesis when it is in fact true. A Type II error would occur if the smoke detector does not sound an alarm when there is a fire, meaning failing to reject the null hypothesis when it is in fact false.

Considering the consequences of these errors, a Type II error would be more severe in this scenario, as it could lead to a serious danger not being recognized, potentially resulting in damage or harm.

Step-by-step explanation:

~ Let us apply a compound interest formula not through substituting values, but through a similar way of following this formula ~

1. First let us assign the values:

interest ⇒ 6.5 percent ( % ), principle number - start value ⇒ $ 8300, time ⇒  14 years

2. Now let us convert interest ⇒ decimal form: 0.065

3. Add 1 to this value 0.065 ⇒ 1 + 0.065 = 1.065

4. Now let us take 1.065 exponentially to the power of itself 14 times, or in other words to the power of time ( 14 years ): 1.065^ 14 = 2.414874185.......

5. Multiply this infinite number by the principle number P, or most commonly known as the start value: 2.414874185....... * 8300    ⇒    

(About) 20043.46 after 14 years

Using the formula for compound interest and substituting accordingly, the given investment grows to approximately 18,108.80 dollars after 14 years.

To solve this, we'll use the formula for compound interest, which is P(1 + r/n)^(nt), where P is the principle amount (initial investment), r is the annual interest rate, n is the number of times that interest is compounded per unit t, and t is the time the money is invested for.

In this case, P = 8300 dollars, r = 6.5/100 = 0.065 (we need the rate in decimal form), n = 1 (since the interest is given annually), and t = 14 years.

Substitute these values into the formula:

A = 8300(1 + 0.065/1)^(1*14) which simplifies to A = 8300(1.065)^14.

Using a calculator, A ≈ 18,108.80 dollars. So, after 14 years, the account will have approximately 18,108.80 dollars.

An ISOSCELES TRIANGLE

Step-by-step explanation:

Given a triangle ABC with vertices at A(-5, 4), B(4, 1), and C(1, -8), to know the type of triangle this is, we need to find the three sides of the triangles by taking the distance between the points.

Distance between two points is expressed as:

D = √(x2-x1)²+(y2-y1)²

For side |AB|:

A(-5, 4) and B(4, 1)

|AB| = √(4-(-5))²+(1-4)²

|AB| = √9²+3²

|AB| = √90

For side |BC|

B(4, 1), and C(1, -8)

|BC| =√(1-4)²+(-8-1)²

|BC| = √3²+9²

|BC| = √90

For side |AC|:

A(-5, 4) and C(1, -8).

|AC| = √(1-(-5))²+(-8-4)²

|AC| = √6²+12²

|AC| = √36+144

|AC| = √180

Based on the distances, it is seen that side AB and BC are equal which shows that two sides of the triangle are equal. A triangle that has two of its sides to be equal is known as an ISOSCELES TRIANGLE. Therefore the term that correctly describes the triangle is an isosceles triangle.
