Answer:
n= 1.25
Step-by-step explanation:
multiply both sides by 3 giving you 1.25
Answer:
where is the table
Step-by-step explanation:
The correct answer is -48
36 + x = -12
X = -12 - 36
x = -48
36 + (-48) = -12
36 - 48 = -12
<span>The <u>correct answer</u> is:
A) 60% ± 18%.
Explanation:
In a confidence interval, the margin of error is given by z*(</span>σ/√n<span>), where </span>σ<span> is the standard deviation and n is the sample size.
First we <u>find the value of z</u>:
We want a 95% confidence level; 95% = 95/100 = 0.95.
To find the z-score, we first subtract this from 1:
1-0.95 = 0.05.
Divide by 2:
0.05/2 = 0.025.
Subtract from 1 again:
1-0.025 = 0.975.
Using a z-table, we find this value in the middle of the table. The z-score that is associated with this value is 1.96.
Back to our formula for margin of error, we have 1.96(</span>σ<span>/</span>√n<span>). The larger n, the sample size, is, the larger its square root is. When we divide by a larger number, our answer is smaller; this gives us a smaller margin of error.
This means that if we had a small sample size, we would divide by a smaller number, making our margin of error larger. The largest margin of error we have in this question is 18%, so this is our correct answer.</span>
Answer:
pretty sure it's just 9
Step-by-step explanation:
Let's assume the possible numbers are 1,2,3,4,5
There are only 3 numbers less than 4 (1,2,3) which means that there are 3*3 possbiblities out of the two spots
There's only 1 number greater than 4 (5) which means the third, fourth, and fifth are just 5
which means the answer is just 9
