Jennifer has been saving for college for 57 months. The first month, she saved $11. She was able to save more money each month t

Ivanshal [37]

This is an arithmetic sequence with first term (a) = 11, number of terms (n) = 57, sum of nth term (Sn) = 19,779.
Let the amount of money she saved more each month be d, then
Sn = n/2(2a + (n - 1)d)
19,779 = 57/2(2(11) + (57 - 1)d)
19,779 = 28.5(22 + 56d)
19,779 = 627 + 1,596d
19,779 - 627 = 1,596d
d = 19,152/1,596 = 12

Therefore, she saved $12.00 more each month.

ElenaW [278]

Answer: The margin of error = $3\%$

Step-by-step explanation:

Given

Sample size (n) = 1000

Population proportion = 0.4

$\alpha$ = 1 - confidence level

= 1 - 0.95

= 0.05

$margin\; of\; error = z_{\frac{\alpha }{2}}\sqrt{\frac{{\widehat{p}}{(1 -\widehat{p})}}{n}}$

$margin\; of\; error = z_{\frac{0.05 }{2}\sqrt{\frac{{(0.4)}{(1 -0.4)}}{1000}}$

$= z_{0.025}\sqrt{\frac{{(0.4)}{(0.6)}}{1000}}$

$= 1.96\sqrt{\frac{{(0.4)}{(0.6)}}{1000}}$

= 0.03

The margin of error change to $2.5\%$ to $3\%$
