Problem 1: the accompanying data describe flexural strength (mpa) for concrete beams of a certain type. calculate a point estimate for the mean value of the strength of the population of beams manufactured in this fashion. 9.2 9.7 8.8 10.7 8.4 8.7 10.7 6.9 8.2 8.3 7.3 9.1 7.8 8.0 8.6 7.8 7.5 8.0 7.3 8.9 10.0 8.8 8.7 12.6 12.3 12.8 11.7

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
