Both students are correct
Step-by-step explanation:
12 divided by 3 is 4
12 * 1/3 = 12/3 = 4
The same has the teacher answer key
Answer: a. 0.542
b. 0.051
c.
Step-by-step explanation:
Let p be the population proportion of parents spend too little time with their children because of work commitments
As per given , we have
n= 369
Since the sample proportion is the best estimate for the population proportion.
So , the point estimate of the proportion of the population of working parents who feel they spend too little time with their children because of work commitments = 0.542
z-value for 95% confidence interval :
Margin of error :
The margin of error = 0.051
Confidence interval :
95% confidence interval estimate of the population proportion of working parents who feel they spend too little time with their children because of work commitments :
Step-by-step explanation:
We distribute first:
(9.5*a)+(9.5*4)= 9.5a+38
We can subtract the a from 9.5a.
9.5a-a=8.5a
The answer is 8.5a+38
I'm so sorry if i'm wrong!
They can both be divided by 2, so you would divide 4 by 2 which is 2 and then 6 by 2 which is 3. it simplifies to 2/3
It is A.
V=length x width x height
3x9=54
54x9=486
