Answer:

7. Distributive Property

8. 8x +2.5

Step-by-step explanation:

7. The equation matches the pattern ...

a(b + c) = ab + ac . . . . . . . statement of Distributive Property

with a=√2, b=5, c=4

8. The one-time charge of 2.50 will appear added in the equation one time (and not multiplied by anything). The number of tickets (x) will be multiplied by the ticket charge (8) and added to the one-time charge. Only one answer choice does that:

8x + 2.5

How to find g(x) from parent function f(x)=2x-1 when the vertical translation is 4 units down

Ivan

g(x), the new function, is shifted down 4 from the original f(x)=2x-1

Shifting down 4 is negative, so it would be subtracting 4 from the original

g(x)= 2x-1 -4

g(x) = 2x-5

The mean score of 8 players is 14.5. If the highest individual score is removed the mean of the score of the remaining 7 players

AfilCa [17]

Answer:

The highest score is 32.

Step-by-step explanation:

We are given the following in the question:

The mean score of 8 players is 14.5.

Let x denote the highest score.

If x is removed, the mean of the score of the remaining 7 players is 12.

Formula for mean:

$\bar{x} = \dfrac{\displaystyle\sum x_i}{n}$

Putting values, we get:

$14.5 = \dfrac{\displaystyle\sum x_i}{8}\\\\\Rightarrow \displaystyle\sum x_i = 116\\\\12 = \dfrac{\displaystyle\sum y_i}{7}\\\\\Rightarrow \displaystyle\sum y_i = 84\\\\\displaystyle\sum y_i = \displaystyle\sum x_i -x \\\\84 = 116 - x\\\Rightarrow x = 32$
