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:

  8 feet

Step-by-step explanation:

The length can be found using the volume formula with the known values. The resulting equation can be solved for the unknown value.

__

  V = LWH . . . . . volume of a prism is the product of its dimensions

  108 ft³ = l×(3 ft)×(4.5 ft) . . . . . known values filled in

  l = 108 ft³/(13.5 ft²) = 8 ft . . . . . . divide by the coefficient of length

The length of the prism is 8 feet.

Answer:

8ft

Step-by-step explanation:

The number of trucks needed to deliver the rock in one trip will be 6.

Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:

V =  a x b x c

A transport company needs to deliver 500,000 pounds of rocks to a construction site.

The company owns a set of dump trucks- each with a container in the shape of a rectangular prism (figure A).

If each pound of rock has a volume of 0.01 cubic feet.

Then the total volume of rock that the transport company is responsible for.

Volume of rocks = 0.01 x 500,000

Volume of rocks = 5,000 ft³

Then the maximum volume of each dump truck will be

Volume of truck = 12 x 9 x 8

Volume of truck = 864 ft³

Then the number of the trucks are needed to deliver the rock in one trip will be

Number of trucks = 5000 / 864

Number of trucks = 5.787

Number of trucks ≅ 6

Answer:

The way the problem is written: y = 8x/3 - 20/3

If the two numbers are the same: the number is 4.

Step-by-step explanation:

She thought of 2 numbers.

The first number is x.

The second number is y.

8(x - 5/2) = 3y

We have one equation with two variables, so we do not have enough information to find the two numbers.

We can just express one number in terms of the other number.

8x - 20 = 3y

3y = 8x - 20

y = 8x/3 - 20/3

If the problem were:

"Amina thinks of a number and subtracts 5/2 from it. She multiplies the result by 8. The result now obtained is 3 times the same number she thought of. What is the number?",

then there is only one variable, and we can find the number.

8(x - 5/2) = 3x

8x - 20 = 3x

5x = 20

x = 4

The number is 4.

Answer:X is equal to -4 twice

Step-by-step explanation:

The solution to the equation 2x² + 8x = x² - 16 is x = -4.

Option A is the correct answer.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We also find the solution in a system of equations using the substitution or elimination method.

Example:

2x + 4 = 8

The solution is x = 2.

We have,

To solve the equation 2x² + 8x = x² - 16, we first simplify it by moving all the terms to one side:

2x² + 8x - x² + 16 = 0

Simplifying further, we get:

x² + 8x + 16 = 0

This is a quadratic equation of the form ax² + bx + c = 0, where a = 1, b = 8, and c = 16.

We can solve this equation by factoring it:

(x + 4)(x + 4) = 0

This gives us two solutions:

x + 4 = 0 or x + 4 = 0

x = -4 or x = -4

Therefore,

The solution to the equation 2x² + 8x = x² - 16 is x = -4.

The Probability of that more than 7 of them germinate is 0.2948.

We are to determine the probability that more than 7 of 10 seeds (i.e. 8, 0r 9 0r 10) germinate.

The probability that all 10 seeds germinate is equal 0.80¹⁰= 0.1073 = 10.73%.

The probability that only the first (only the second, etc ) seed does not germinate is equal 0.20 X 0.80⁹= 0.0268 = 2.68%.

The probability that 6 seeds germinate is the sum of the probabilities that only the first seed does not germinate, only the second one does not germinate, etc, and equals to 10 X 0.0268  = 0.268 = 26.8%.

The total probability that more than 7 of 10 seeds germinate is the sum of the probabilities that 10 seeds germinate and that 7 seeds germinate, i.e. 2.68 % + 26.8 % = 29.48 %.

Thus, The Probability of that more than 7 of them germinate is 0.2948.

Answer:

(8w + 7)(7w + 9)

Step-by-step explanation:

56w² + 121w + 63

consider the factors of the product of the coefficient of the w² term and the constant term which sum to give the coefficient of the w- term

product = 56 × 63 = 3528 and sum = 121

After much trial and error the factors are + 49 and + 72

use these factors to split the w- term

56w² + 49w + 72w + 63 ( factor first/second and third/fourth terms )

= 7w(8w + 7) + 9(8w + 7) ← factor out (8w + 7) from each term

= (8w + 7)(7w + 9) ← in factored form
