Answer:
<h2><u><em>
6 feet</em></u></h2>
Step-by-step explanation:
Find the height of a square pyramid that has a volume of 8 cubic feet and a base length of 2 feet
Volume v = 1/3*a²h
inverse formula
8 = 1/3 * 2² * h
8 = 4 h /3
divide both the sides by 4
<u><em>h = 6 feet</em></u>
height=x
length=20-2(what u cut out)=20-2x
width=30-2(what u cut out)=30-2x
so v(x)=l*w*h=x(20-2x)(30-2x)
b) (0,10)
Answer:
Step-by-step explanation:
No of citizens participated in the survey =n =500
No of people who believe the government's highest priority should be foreign relations.=70
Sample proportion = p = 
q = 1-p = 1-0.14 = 0.86
Std error of proportion= 
Concept used:Sample proportion p follows a normal distribution with mean =p and std error = sq rt pq/n
