Okay, so the formula for a confidence interval is
test statistic +/- (critical value)(standard deviation of statistic
44 +/- (invNorm(area: 0.05, u=0, std:1))(14.5)
44 +/- 23.85
(20.15, 67.85)
hope this helps :)

This is the area of a triangle and a square
Area of a triangle is 1/2BH
here total height is 16 in triangle h is 16-10=6
base is 10
A=1/2*10*6
A=30 inch^2
Area of square=a^2
A2=10^2=100inches^2
A1+A2=100+30
130inches^2
Answer:
x = ± 
Step-by-step explanation:
Given
ax² + b = c ( subtract b from both sides )
ax² = c - b ( divide both sides by a )
x² =
( take the square root of both sides )
x = ±
