Using the Central Limit Theorem, the state that the sample mean would most likely be within $80 of $2,600 is given by:

c. Equally likely because σ = $800 for both states.

It states that the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this problem, we have that for both states, [tex]\sigma = 800, n = 100[/tex], hence they have the same standard error, being equally as likely to be within $80 of $2,600, meaning that option C is correct.

Answer:

Step-by-step explanation:

The probability of getting first marble is red and the second

marble is blue is 4/15.

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes.

Given that:

Number of red marbles= 8

Number of blue marbles= 7

Total Number of marbles= 8+7 = 15 marbles.

P(red Marble) =[tex]\frac{8}{15}[/tex]

No replacement, now the total marbles = 14

P( blue marbles) = 7/14

Now, P( first marble is red and the second marble is blue.)

= 8/15*7/14

= 4/15

Hence, the probability of getting first marble is red and the second

marble is blue is 4/15.

The mean of the age data of the players is 20 and on average the age of each player is 1 far from mean.

The dot plot is the way of representation of the data. This data is plotted in the form of points or dots over an x-y axis. The dot plot is also known as the strip plot.

The data of the age of the player is,

18,19,20,21,21,21

The number of player are 6. Thus, the mean of the data is,

Mean=(18+19+20+21+21+21)/6

Mean=20

The distance form mean 20 of each player age is, 2,1,0,1,1,1. The mean deviation is,

Mean Deviation= (2+1+0+1+1+1)/6

Mean Deviation=1

Thus, the mean of the age data of the players is 20 and on average the age of each player is 1 far from mean.

Answer:

She left at 7:55

Step-by-step explanation:

She travels 150 miles at 50 miles an hour, it takes her 3 hours to get to stoke but she stopped for 20 minutes. Subtract 20 minutes from 11:15, and you get 10:55, then subtract 3 hours. You get 7:55. This means she left the house at 7:55.

Answer: The answer is [tex]16[/tex], You need to reduce the expression, if possible, by canceling the common factors. Then its lateral area of 12 inches and the radius of 3/4 inches would be 16.

Therefore your answer would be [tex]16[/tex].

Based on the concrete of the lateral area and the content of the question, the right answer is 18π

The lateral area is the term that is used to describe the surface of an object as all of the sides of the object, excluding its base and top. Generally, the term lateral area is different from the surface area, which is the lateral surface area together with the areas of the base and top.

Hence, in this case, to calculate the lateral area of the paint roller, find the circumference of the roller and multiply it by its length.

The circumference of a circle can be found using the formula: C = 2πr where r is the radius.

Given that the roller has a radius of 3/4 inch let's substitute this value into the formula to find the circumference:

C = 2π(3/4)

C = 6π/4

C = 3π/2

Now we have the circumference of the roller.

To find the lateral area we multiply the circumference by the length of the roller which is 12 inches:

Lateral Area = Circumference x Length

Lateral Area = 3π/2 x 12

Lateral Area = 36π/2

Lateral Area = 18π

Therefore, in this case, it is concluded that the lateral area of the paint roller is 18π square inches.

If Rob receives $4,585.75 in annual dividends, the number of shares of Agram Imports that Rob owns is D. 441 shares.

A dividend is the distribution of cash or stock that a company makes to its stockholders periodically.

Dividends are usually based on a dividend payout ratio, determined by the Board of Directors of the company.

                                       Dowc Beverage Co.     Agram Imports

Dividend per share                 $6.52                               $5.15

Number of shares                    x                                     x+ 86

Number of shares                 355 (441 - 86)                  441 (355 + 86)

Total dividend received      $2,314.60 ($4,585.75 - $2,271.15))  $2,271.15

which is equivalent to $2,314.60 ($355 x $6.52)

Assuming total shares from Agram Imports to be 441, the total dividends will be $2,271.15 ($5.15 x 441), and, the dividend from Dowc Beverage Co. will be $2,314.60 and the number of shares will be 355 ($2,314.60/$6.52), which is 86 less than the shares in Agram Imports.

Thus, if Rob receives $4,585.75 in annual dividends, the number of shares of Agram Imports that Rob owns is D. 441 shares.

Answer:

58.5; 300; 196.5

Step-by-step explanation:

Area of triangle 1 = (1/2) * 9 * 13 = 58.5 inches^2

Area of whole figure = (1/2) * (14+26) * 15 = 300 inches ^2

Area of shaded region = 300 - 58.5 - [(1/2) * 6 * 15] = 241.5 - 45 = 196.5 inches^2

Answer:

113.04 yd²

Step-by-step explanation:

The formula for finding the surface area of a cylinder is:

2πrh+2πr² r = radius, h=height

The radius of this cylinder is 2, so you replace the 'r' with '2.' The height is 7 yd, so you replace the 'h' with '7.' Use 3.14 for π.

2πrh+2πr²

2(3.14)(2)(7) + 2(3.14)(2)^2

= 113.04 yd²

Bajo la suposición de que las ciudades se hallan en la misma latitud, la distancia estimada entre las dos ciudades es de aproximadamente 6814 kilómetros.

En esta pregunta asumimos que la Tierra tiene una geometría esférica, de modo que los cálculos de arcos circulares se pueden obtener de manera simple y ágil. Por otra parte, también asumimos que las que la ciudad de Londres se encuentra a la misma latitud que la ciudad de Nueva York.

Es posible determinar la distancia estimada mediante la siguiente ecuación de arco circular:

Step-by-step explanation:

Keyshawn starts off with 100 baseball cards. Each week he buys 25 more baseball cards. Given this we want to find an equation that would represent the number of baseball cards (represented by "b") he would have after a number of weeks (represented by "w")

We know that keyshawn buys 25 baseball cards weekly so the number of baseball cards purchased after w weeks can be represented by 25w.

We also know that he started of with 100 baseball cards so the total amount of baseball cards keyshawn has (b) can be represented by the expression b = 25w + 100

Answer:

6

Step-by-step explanation:

g(f(0)) means that the input of f(x) is 0 and this value of f(x) found is the input of g(x). This is known as composite functions.

Let's find the value of f(0).

f(x)= x²

f(0)= 0²

f(0)= 0

Now, we can find the value of g(f(0)).

g(x)= x +6

g(f(0))

= g(0)

= 0 +6
