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:

Favorable outcomes: 1 -- HH

Possible outcomes: 4 -- HH, HT, TH, TT

Thus, the probability that the coin will land heads both times is [tex]\frac{1}{4}[/tex].

If Dan grabs one sock from a drawer containing 3 white socks, 4 blue socks, and 5 yellow socks, what is the probability that he will grab a white sock?

Favorable outcomes: 3 (3 white socks)

Possible outcomes: 12 (3 white socks + 4 blue socks + 5 yellow socks)

Thus, the probability that Dan will grab a white sock is [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex].

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]

[tex]V=48\pi\cdot\sqrt{256}[/tex]

[tex]V=48\pi\cdot16[/tex]

[tex]V=2412.743157[/tex]

[tex]V\approx 2412.74[/tex]

Therefore, the volume of the cone is approximately 2412.74 cubic inches.

Hey there :)

To find the slope with two points we will need to use the equation  [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]

Here is what the equation should look like when replaced with the numbers (it will be a fraction) :

                                     [tex]\frac{8 - (-20)}{5 - 3}[/tex]

We know that two negatives cancel out and make a positive, so the numerator would actually be 8 + 20.

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.

Final answer:

To find the numbers Ali picked, we identify the lowest number (11), calculate the highest number using the range (11 + 13 = 24), and confirm that the median (17) fits between these two numbers. Thus, the numbers are 11, 17, and 24.

Explanation:

Ali picked three numbers, and we have been provided with three pieces of information about these numbers: the lowest number was 11, the range was 13, and the median was 17. We can use this information to determine the three numbers Ali picked.

Step 1: Identify the Lowest Number

We know the lowest number is 11. This is our starting point.

Step 2: Determine the Range

The range of a set of numbers is the difference between the highest and the lowest numbers. Since the range is 13, we add this to the lowest number to find the highest number: 11 + 13 = 24. So, the highest number Ali picked is 24.

Step 3: Find the Median

The median is the middle number in a set of numbers that has been arranged in order. We are told the median is 17, which fits perfectly between our lowest and highest numbers, confirming that our calculations are correct.

Therefore, the numbers Ali picked, in order from lowest to highest, are: 11, 17, and 24.

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.

Answer:

(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 )

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.

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.

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
