Answer:
you can do (500)(4) x 2
Step-by-step explanation:
500 x 4 = 2000
2000(2) = 4000

<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:im not sure i wish i can help but goodluck
Step-by-step explanation:
You distribute the 8 to the x and the 2 which leaves you with 8x + 16 = 48 then u subtract the 16 on both sides, subtract 16 - 16 (cancel out) then 48-16 which gives you 32, from there you should have 8x=32 then you divide 8x by 8 and 32 by 8 which leave the x by itself and you 32/8 is 4 so the final answer is x = 4 !!
