You only listed 8 kids...so the average of the 8 kids listed is 150.125!
The process:
You add all kids heights then divide by the amount of children. Like this-
155+160+145+150+147+152+144+148=1201
Then you divide by 8 to get 150.125

Let p(x) = 7x + 5 and r(x) = x - 1. Find and evaluate (r x p) (5)
quester [9]

Answer: 39

Step-by-step explanation:

Given

P(x)=7x+5

r(x)=x-1

r(p(x))=7x+5-1=7x+4

so, r(p(5))

\Rightarrow r(p(5))=7\times 5+4=35+4=39

Because the coefficient of x^2 is -1, we know that a will be -1.  Knowing that the coefficient of x is -4, we can calculate that p=2.  Thus, we have -1(x+2)^2+q is our equation.  This is equal to -x^2-4x-4+q.  As the constant term must be 2, we can then see that q is 6.

As such, we have -1(x+2)^2+6=0 as our factorization.

To solve this equation, we can use the quadratic formula.  Plugging in values, we have:

\frac{4+-2 \sqrt{6} }{-2}
which is equal to: (when the fraction is simplified)
-2+- \sqrt{6}
