Answer:96
Step-by-step explanation:
A; 480/16 = 30 students per classroom
B: 192/12 =16 students per classroom
we need x such that
which means
(480-x )* 12 should be equal to (192+x) * 16
5,760 - 12x = 3,072+16x
5,760 - 3,072 = 12x + 16x
2,688 = 28x
x = 96
Answer: 37
Step-by-step explanation:
Given : Significance level :
Critical value :
margin of error : E= 1 mile per gallon
Population standard deviation: miles per gallon.
We know that when the population standard deviation is known then the formula to find the sample size is given by :
[Round to the next whole number.]
Hence, the required number of automobiles should be used in the test = 37
Answer:
y = - x - 8
Step-by-step explanation:

y = mx + c ( m is the slope and c the y- intercept )
here m = - and c = - 8, hence
y = - x - 8 ← linear equation
