The required probability that the first pitch of the season uses one of your baseballs or one of your uncle's baseballs is 2/5.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

There are 20 baseballs donated between you and your uncle and a total of 50 baseballs, so the probability that the first pitch of the season uses one of your baseballs or one of your uncle's baseballs is:

P(your baseball or uncle's baseball) = (number of your baseballs + number of uncle's baseballs) / total number of baseballs

= (8 + 12) / 50

= 20/50

= 2/5

Therefore, the probability that the first pitch of the season uses one of your baseballs or one of your uncle's baseballs is 2/5.

The probability that the first pitch of the season uses one of the baseballs donated by the student or their uncle is 2/5 or 40%.

To calculate the probability that the first pitch of the season uses one of your baseballs or one of your uncle's, we first need to figure out the total number of baseballs donated by you and your uncle. You donated 8 baseballs and your uncle donated 12 baseballs. Hence, together you both donated 8 + 12 = 20 baseballs.

Since there are a total of 50 baseballs donated, we can now calculate the probability. The probability of picking either one of your baseballs or one of uncle's baseballs is the total number of your combined baseballs divided by the overall total number of baseballs, which is 20/50. This can be simplified to 2/5 or 40%.

Therefore, the probability that the first pitch of the season uses one of the baseballs donated by you or your uncle is 2/5.

Answer:

Hence, the coordinate of point M that divides the line segment AB is [tex](5, \frac{32}{3} )[/tex].

Step-by-step explanation:

Given that,

AB is the line segment, and M divides the line segment AB into a ratio of 2:1.

Coordinate of point A is [tex](-1, 2)[/tex] and Coordinate of point B is [tex](8, 15)[/tex].

Let, the coordinate of point M is [tex](x. y)[/tex].

Now,

The coordinate of a point M, which divides the line segment AB internally in the ratio [tex]m_{1}:m_{2}[/tex] are given by:

                                 [tex]\frac{m_{1}x_{2}+m_{2}x_{1} }{(m_{1}+m_{2}) } ,\frac{m_{1}y_{2}+m_{2}y_{1} }{(m_{1}+m_{2}) }[/tex]

[tex]x[/tex] coordinate of point M is [tex]\frac{(2\times 8)+(1\times -1)}{(2+1)}[/tex] = [tex]\frac{(16-1)}{3} =\frac{15}{3} =5[/tex]

[tex]y[/tex] coordinate of point M is [tex]\frac{(2\times 15)+(1\times 2)}{(2+1)}[/tex] = [tex]\frac{30+2}{3} = \frac{32}{3}[/tex]

Hence, the coordinate of point M that divides the line segment AB is [tex](5, \frac{32}{3} )[/tex].

Answer: L(t)= 7600 times 5^t/22

Step-by-step explanation:

kahn answer

To model the locust population, we can use an exponential growth function. The initial population is given as 7600, and it increases by a factor of 555 every 222222 days. The function is L(t) = 7600 * 555^(t/222222).

To model the locust population, we can use an exponential growth function. The initial population is given as 7600. The population increases by a factor of 555 every 222222 days. Let's denote the time since the first day of spring as t. The function can be written as:

L(t) = 7600 * 555^(t/222222)

For example, if we want to find the locust population after 1 year (365 days), we can substitute t = 365 into the function:

L(365) = 7600 * 555^(365/222222)

By evaluating this expression, we can determine the locust population at any given time since the first day of spring.

Question:

A. The middle 95% of Jiffy Corn Muffin Mix boxes contain between _____ and ________ounces of cereal

Answer:

Therefore the middle 95% of Jiffy Corn Muffin Mix boxes contain between _9.994____ and _10.0062_______ounces of cereal

Step-by-step explanation:

The question requires us to construct the 95% confidence interval of the normal distribution as follows;

The mean, μ = 10

The sample standard deviation, σ = 0.1

Assumption

Number of boxes, n = 1000

The formula for confidence interval is as follows;

[tex]CI= \mu \pm z\frac{\sigma}{\sqrt{n}}[/tex]

Where, z at 95% confidence level is given as ±1.96

Plugging in the values, we have;

[tex]CI=10 \pm 1.96 \times \frac{0.1}{\sqrt{1000}}[/tex]

Therefore the middle 95% of Jiffy Corn Muffin Mix boxes contain between _9.994____ and _10.0062_______ounces of cereal.

Answer:

Out of 240,000 feet² of the field 62,800 feet² was being watered.

Step-by-step explanation:

We have a figure with 32 circles and diameter of each circle is 50 feet. We have to find how much area is being watered. Assuming that each circle represents the Area of the field which is being watered.

We can find the area of one circle and multiply that by 32 to find the area of all 32 circles. This will give us the area of the field that is being watered.

Since, radius is half of the diameter, the radius of each circle will be r = 25 feet.

Area of a circle is calculated as:

Area = πr²

Substituting the value of r = 25 and π = 3.14, we get:

Area of one circle = 3.14 x (25)² = 1962.5 feet²

Since area of 1 circle is 1962.5 feet² , area of 32 circles will be = 32 x 1962.5 = 62,800 feet²

The field is rectangular in shape with length = 600 feet and width = 400 feet.

Area of a rectangle is the product of its length and width. So area of the entire field will be:

Area of field = 600 x 400 = 240,000 feet²

This means, out of 240,000 feet² of the field 62,800 feet² was being watered.

Answer:

Step-by-step explanation:

Let x represent the number of apples that she wants to buy.

The grocery store sells apples for $1 each and mangos for $0.50 each.

If Gabriella decided to buy 13 mangos, it means that the cost of buying x apples and 13 mangoes is expressed as

x + 13 × 0.5 = x + 6.5

If she buy at least 19 apples, it means that

x + 13 ≥ 19

x ≥ 19 - 13

x ≥ 6

Gabriella has $15 to spend. It means that

x + 6.5 ≤ 15

x ≤ 15 - 6.5

x ≤ 8.5

Therefore, the maximum number of apples that she can buy is 8

Final answer:

After purchasing 13 mangos, Gabriella can spend the remaining $8.50 on apples, which allows her to buy a maximum of 8 apples while also meeting the minimum requirement of 19 fruits in total.

Explanation:

If Gabriella decided to buy 13 mangos at $0.50 each, she would spend $6.50 on mangos. She has $15 to spend, so after buying the mangos, she would have $15 - $6.50 = $8.50 left. Since apples cost $1 each, Gabriella could buy a maximum of $8.50/ $1 per apple = 8 apples. However, she must buy at least 19 apples and mangos altogether. Since she has already bought 13 mangos, she would need to buy 19 - 13 = 6 apples to meet the minimum requirement. Therefore, the maximum number of apples she can buy is 8, which also satisfies the minimum quantity of fruit required.

The minimum unit cost to manufacture a car for the given quadratic cost function C(x) = 0.5x^2 - 130x + 17,555 is found by using the vertex formula. The x-coordinate of the vertex is -(-130)/(2*0.5) = 130, which yields the minimum unit cost of $9,105 when substituted back into the function.

To find the minimum unit cost for manufacturing cars in the given scenario, we need to analyze the cost function C(x) = 0.5x2 - 130x + 17,555. This is a quadratic function, which is parabolic in shape, generally either opening upwards or downwards. In this case, we have a positive coefficient for the x2 term, which means the parabola opens upwards and the vertex of this parabola will give us the minimum point or the minimum cost for producing cars.

The vertex of a quadratic function expressed in the form ax2 + bx + c can be found using the formula -b/(2a) for the x-coordinate of the vertex. In this case, a = 0.5, b = -130, so the x-coordinate of the vertex is -(-130)/(2*0.5) = 130. Plugging this value into the original function will give us the minimum unit cost C(130).

The calculation is as follows:

C(130) = 0.5 * (130)2 - 130 * (130) + 17,555

C(130) = 0.5 * 16,900 - 16,900 + 17,555

C(130) = 8,450 - 16,900 + 17,555

C(130) = 9,105

Therefore, the minimum unit cost to manufacture a car in this scenario is $9,105.

Answer:

0.363

Step-by-step explanation:

Number of Black(B) Socks =5

Number of Grey(G) Socks =7

Number of White(W) Socks =13

Total Number of Socks=5+7+13=25

If the two socks are picked one after the other, the total number reduces and the number of that particular color of socks picked also reduces.

To pick the same color, they could either be both black, grey of white.

Therefore:

P(they are of the same color)=P(BB)+P(GG)+P(WW)

[tex]=(\frac{5}{25}X\frac{4}{24})+(\frac{7}{25}X\frac{6}{24})+(\frac{13}{25}X\frac{12}{24})\\=0.363[/tex]

The probability that they are of the same color is 0.363 correct to 3 significant figures.

If the experiment is repeated with 50 spins, the prediction for the number of spins that will land on green is 5

From the question, we have the following parameters that can be used in our computation:

The table of values

Calculate the total number of spins

So, we have

Total spins = 5  + 3 + 1 + 1

Total spins = 10

We have that

The frequency of landing on green is 1

The experimental probability of landing on green is then represented as

[tex]\[ \text{Probability of green} = \frac{1}{10} \][/tex]

Using the experimental probability to predict the number of spins that will land on green in 50 spins, we have

Predicted number of green spins = [tex]\frac{1}{10} \times 50 = 5[/tex]

So, if the experiment is repeated with 50 spins, the prediction for the number of spins that will land on green is 5

Answer:

  C)  y = (1/4)^(-x)

Step-by-step explanation:

The average rate of change on an interval [a, b] is found using the formula ...

  arc = (f(b) -f(a))/(b -a)

For an exponential function with base b on interval [2, 3], the rate of change is ...

  arc = (b^3 -b^2)/(3 -2) = b^2(b -1)

This expression assumes a positive sign on the exponent.

We can compute the arc for each answer choice as ...

  (reference) 1/3^-x = 3^x ⇒ arc = 3²(3 -1) = 18

  A) 2^x ⇒ arc = 2²(2 -1) = 4

  B) 5^(x-2) = (1/25)5^x ⇒ arc = (1/25)(5²)(5 -1) = 4

  C) 1/4^-x = 4^x ⇒ arc = 4²(4 -1) = 48

  D) (2/3)^-x = (3/2)^x ⇒ arc = (3/2)²(3/2 -1) = 9/8

An average rate of change greater than 18 is demonstrated by (1/4)^-x.

Answer:

(x-10) (x+8)

Step-by-step explanation:

x^2 – 2x – 80.

What two numbers multiply to -80 and add to -2

-10*8 = -80

-10+8 = -2

(x-10) (x+8)

=====================================================

Explanation:

The last term is -80 and the middle coefficient is -2

Find two numbers that

Those two numbers are 8 and -10

which is why the original expression factors to (x+8)(x-10)

We can use the FOIL rule to expand out (x+8)(x-10) to end up with x^2-10x+8x-80 = x^2-2x-80, which confirms we have the correct factorization. You can use the box method as an alternative.

Answer:

4 days

Step-by-step explanation:

She recorded date for 16 days, and 1/4 of the days were clear blue skies.

One way to find this is to multiply 16 and 1/4

16*1/4=4

Another way is to first convert 1/4 to a decimal

1/4=0.25

Then multiply 16 and 0.25

16*0.25 =4

So, 4 out of 16 days had clear blue skies

There are 4 different flower boxes with different-size bases that can hold exactly 16 cubic feet of soil when using whole-number dimensions. These consist of dimension combinations of 1x1x16, 1x2x8, 1x4x4, and 2x2x4 feet.

Mrs. Wilton is planning a rectangular flower box that should have a volume of 16 cubic feet. To find how many flower boxes with different-size bases can hold exactly 16 cubic feet of soil, we need to find all the possible combinations of whole-number dimensions (length, width, and height) that when multiplied together equal 16 cubic feet. We must remember that volume is calculated as Length x Width x Height. Since 16 is the volume in cubic feet, we look for whole-number factors of 16.

Here are the possible whole-number dimension sets (in feet) for a volume of 16 cubic feet:

1 x 1 x 16 (Height can be 1, 16, or any factor of 16)

1 x 2 x 8 (Height can be 2, 8, or any factor of 16)

1 x 4 x 4 (Height can be 4 or any factor of 16)

2 x 2 x 4 (These dimensions are interchangeable)

Each of these dimensions gives a different base size for the flower box, and all ensure the volume is 16 cubic feet. Thus, there are 4 different flower boxes with different-size bases that will hold exactly 16 cubic feet of soil.

The original price of the game was £18. This is derived by understanding a 1/2 increase equates to a 50% increase, thus making £27 150% of the original price. To get the original price, divide £27 by 1.5.

To solve this problem, you need to understand that an increase of 1/2 equals a 50% increase. If the game price were £27 after increasing by 50%, that means £27 represents the original price plus an additional half (50%) of the original price, in other words, it represents 150% of the original price. We can set up the equation like this:

Original Price(1.5) = £27

To solve for the original price, we divide £27 by 1.5, resulting in £18.

So, the original price of the game was £18.
