Answer:  5/19

Step-by-step explanation:

There is a  total of 20 tickets numbered from 1 to 20.

10 of the tickets has even number and 10 of the tickets have odd numbers.

probability of drawing a ticket that has even number =10/20 which is equal to 1/2

there are total 19 tickets and 10 odd tickets are available.

Probability of drawing a ticket that has odd number =1019

probability =1/2∗10/19=5/19

Answer:

a. 5/19, b. 14/95

Step-by-step explanation:

a. since the first number drawn has 10/20 chance of being even and it's not put back (you assume that you pull an even #), so the second number pulled has a 10/19 chance of being odd.

10/20*10/19 = 5/19

b. 2, 3, 5, 7, 11, 13, 17, 19 are the prime numbers, so 8/20 for the first pull and then 7/19 for the second pull

8/20*7/19 = 14/95

The vertex of the parabola is (-3, -4)

A parabola is defined as a set of points in a plane which are equidistant from a straight line or directrix and focus.

Given:

The solid circles along the parabola are:

(-6, 5), (-5, 0), (-4, -3), (-3, -4), (-2, -3), (-1, 0), (0, 5).

As, the minimum point of y occurs at (-3, -4).

So, the x-intercept of the parabola is

x=-5 or x=-1

x+5=0 or x+1=0

(x+5)(x+1)=0

x² + 6x+ 5 =0

Now, vertex of equation at axis of symmetry x= -b/2a

x= -6/2 = -3

and, f(-3)= -3 * (-3) + 6(-3) + 5

f(-3)= -4

We have been given that a cone has a radius of 12 inches and slant height of 20 inches. We are asked to find the volume of the cone.

We will use volume of cone formula to solve our given problem.

[tex]V=\frac{1}{3}\pi r^2\sqrt{l^2-r^2}[/tex], where

V = Volume of cone,

r = Radius,

l = Slant height.

Upon substituting our given values in volume formula, we will get:

[tex]V=\frac{1}{3}\pi\cdot 12^2\cdot \sqrt{20^2-12^2}[/tex]

[tex]V=\frac{1}{3}\pi\cdot 144\cdot \sqrt{400-144}[/tex]

Option 3

g(x) = Negative RootIndex 3 StartRoot x + 4 EndRoot; x greater-than-or-equal-to –4

Step-by-step explanation:

Since the graph starts at x = -4 and towards the right, domain is x 》-4

g(x) = -(x + 4)^⅓

Because,

0 = -(-4 + 4)^⅓

0 = 0

The function g(x) for the restricted domain is g(x) = -∛(x-4); x ≥ -4.

The function g(x) for the restricted domain can be determined by analyzing the given information. The function starts at (-4, 0) and curves through the y-axis at (0, 1.5) before passing through point (4, 2). Based on this, the correct function is g(x) = -∛(x-4); x ≥ -4.

(x+4)(x-5)

Step-by-step explanation:

You need to find two numbers that multiply to be -20 but add up to be -1.

Answer:

( x - 5 ) ( x + 4 )

Step-by-step explanation:

When solving quadratic equations it's important to remember that they have 2 solution. We need to work out the factors, sum and the products to successfully factorise the quadratic and solve it. So,

x² - x - 20 = 0

Sum = -1

Product = -20

So we need two numbers that sum to -1 and multiply together to make -20

Factors = -5 and 4

x² - 5x + 4x - 20

Factor x² - 5x and 4x -20 separately

x² - 5x = x ( x - 5 )

4x - 20 = 4 ( x - 5 ) So

x ( x - 5 ) + 4 ( x - 5 )

We can see a common factor of  ( x - 5 ) and the other bracket would be       ( x + 4)

( x - 5 ) ( x + 4 )

Final answer:

The value of the house at the end of three years would be approximately £123,696.47.

Explanation:

To find the value of the house at the end of three years, we need to calculate the appreciation for each year and add it to the original value. Since the value of the house appreciates by 7.5% each year, we can calculate the value after three years using the formula:

New Value = (1 + Rate of Appreciation) * Original Value

Let's calculate:

The value of the house at the end of the three years would be approximately £123,696.47.

Answer:

Step-by-step explanation:

Two find the final probability asked, first we need to find each probability.

This probability is defined by the sum of the probability of getting a card with S, and a probability of getting a card with E. Remeber, when the probability involves "or", that means sum.

[tex]P_{S \ or \ E} =\frac{1+1}{4}=\frac{2}{4} =\frac{1}{2}[/tex]

There are two tiles only, and one of them is numbered 2. So, its probability is

[tex]P_{2}=\frac{1}{2}[/tex]

There are two discs only. So, the probability of getting a red disc is

[tex]P_{red}=\frac{1}{2}[/tex]

Now, the combined probabilty of all these events can be found by multiplying,  because we want to now the chances of getting all these results which are independent.

[tex]P_{total}=\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} =\frac{1}{8}[/tex]

Therefore, the probability is 1/8.

Answer:

The required probability is [tex]\dfrac{1}{12}[/tex].

Step-by-step explanation:

Let A be the event of rolling the number cube.

Let B be the event of tossing the coin.

Total number of possibilities of rolling the number cube and tossing the coin are 12 here.

[tex]\{(1,H),(2,H),(3,H),(4,H),(5,H),(6,H),(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)\}[/tex]

where H means Head on toss of coin and T means Tails on toss of coin.

Formula for probability of an event E is:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Here, we have to find the probability of event 'E' i.e. getting a 6 on number cube and heads on coin.

Number of favorable cases are 1 and total cases are 12.

Step-by-step explanation:

To find the total yards of ribbon, convert the length of each piece of ribbon from feet to yards and multiply it by the total number of pieces. James bought 707 yards of ribbon.

To find the total yards of ribbon, we need to convert the length of each piece of ribbon from feet to yards and then multiply it by the total number of pieces.

Since 1 yard is equal to 3 feet, we can use the conversion factor of 1 yard/3 feet to convert each piece of ribbon from feet to yards.

2.1 feet x (1 yard/3 feet) = 0.7 yards

Now, we can multiply the converted length of each piece of ribbon (0.7 yards) by the total number of pieces (1010) to find the total yards of ribbon:

0.7 yards x 1010 = 707 yards

Therefore, James bought a total of 707 yards of ribbon.

1) If a die is rolled once, determine the probability of rolling a 4: Rolling a 4 is an event with 1 favorable outcome (a roll of 4) and the total number of possible outcomes is 6 (a roll of 1, 2, 3, 4, 5, or 6). Thus, the probability of rolling a 4 is [tex]\frac{1}{6}[/tex].

If a die is rolled once, determine the probability of rolling at least a 4: Rolling at least 4 is an event with 3 favorable outcomes (a roll of 4, 5, or 6) and the total number of possible outcomes is again 6. Thus, the probability of rolling at least a 4 is [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex].

If a coin is flipped twice, determine the probability that it will land heads both times:

Final Answer:

The magnitude of the resultant force when two 10 pound forces act on the same object 135° apart is approximately 18.47 pounds.

Explanation:

To find the magnitude of the resultant force when two forces are acting at an angle to each other, we can use the law of cosines. In this scenario, we have two forces each of 10 pounds acting on an object with an angle of 135° between them. Let's denote the forces as F1 and F2, both of which have magnitudes of 10 pounds. The angle between them is θ = 135°.

The formula for the resultant force R when two forces act at an angle θ is:

[tex]\[ R = \sqrt{F1^2 + F2^2 + 2 \cdot F1 \cdot F2 \cdot \cos(θ)} \][/tex]

In our case:

[tex]\[ F1 = F2 = 10 \, \text{pounds} \][/tex]

[tex]\[ θ = 135° \][/tex]

Plugging these values into the formula, we get:

[tex]\[ R = \sqrt{10^2 + 10^2 + 2 \cdot 10 \cdot 10 \cdot \cos(135°)} \][/tex]

[tex]\[ R = \sqrt{100 + 100 + 200 \cdot \cos(135°)} \][/tex]

The cosine of 135° is -√2/2 (since 135° is in the second quadrant where the cosine is negative):

[tex]\[ R = \sqrt{200 - 200 \cdot \frac{-\sqrt{2}}{2}} \][/tex]

[tex]\[ R = \sqrt{200 + 100\sqrt{2}} \][/tex]

[tex]\[ R = \sqrt{200 + 100 \cdot 1.414} \] (Since √2 is approximately 1.414)[/tex]

[tex]\[ R = \sqrt{200 + 141.4} \][/tex]

[tex]\[ R = \sqrt{341.4} \][/tex]

[tex]\[ R \approx 18.47 \text{ pounds} \][/tex]

Therefore, the magnitude of the resultant force when two 10 pound forces act on the same object 135° apart is approximately 18.47 pounds.

Final answer:

The minimum amount of paper needed to make the paper cup to the nearest whole cm² is approximately 283 cm².

Explanation:

To find the minimum amount of paper needed to make the paper cup, we need to calculate the surface area of the cup. The formula for the surface area of a cylinder is:

A = 2πrh + π[tex]r^2[/tex]

Given that the height (h) of the cup is 9 cm and the radius (r) of the circular opening is 2.5 cm, we can plug in the values to calculate the surface area:

A = 2 × 3.14159 × 2.5 × 9 + 3.14159 × [tex]2.5^2[/tex]

Simplifying the equation, we get:

A ≈ 282.74 [tex]cm^2[/tex]

Rounding to the nearest whole , the minimum amount of paper needed is approximately 283 [tex]cm^2.[/tex]

Answer:

0.8 kilograms of fertilizer

Step-by-step explanation:

Looking at the data given to us in a fraction form, we can imagine:

4 kilograms / 5 weeks

To find out how many kilograms of fertilizer was used each week, we're going to divide that fraction out, so we're going to do 4 divided by 5. Dividing this will give you:

0.8 kilograms

Therefore your answer is that they use .8 kilograms of fertilizer each week.

Question;

1) The shaded plants set has greater variability because more data is clustered around the median.

2) The sets are equally variable because the ranges of the data sets are equal.

3) The full sun plants set has greater variability because the IQR for full sun plants is greater.

Answer:

The correct option is;

3) The full sun plants set has greater variability because the IQR for full sun plants is greater

Step-by-step explanation:

To answer the question, we present the dot plot as follows;

Heights of Shaded plants (inches)

          0       4      3       2      0       0             1

0       1.5      2     2.5     3     3.5     4           4.5

We calculate the five numbers as follows;

Max = 4.5

Min = 2

1st quartile = (10+1)/4 th term = 2

2nd quartile (Median) = (10+1)/2 th term = 2.5

3rd quartile = 3×(10+1)/4 th term = 3

Interquatile range (IQR) = Q₃ - Q₁ = 3 - 2 = 1

Where:

Q₁ = 1st quartile

Q₃ = 3rd quartile

Heights of Full Sun plants

0     1      0      2      0       4         3

1.5   2    2.5    3     3.5     4        4.5

We calculate the five numbers as follows;

Max = 4.5

Min = 2

1st quartile = (10+1)/4 th term = 3

2nd quartile (Median) = (10+1)/2 th term = 4

3rd quartile = 3×(10+1)/4 th term = 4.5

Interquatile range (IQR) = Q₃ - Q₁ = 4.5 - 3 = 1.5

The interquartile range, IQR, is a measure of variability

Therefore, the full sun plants set has greater variability because the IQR for full sun plants is greater.
