Katrina wants to estimate the proportion of adults who read at least 10 books last year. to do​ so, she obtains a simple random
Vaselesa [24]
E=Z*sqrt (p(1-p)/N), where E= error margin, p=proportion, N=sample size

Katrina's margin error at 85% confidence interval: E=1.96*sqrt (p(1-p)/100) = 0.196 sqrt (1(1-p))

Mathew's margin error at 99% confidence interval: E= 2.58*sqrt (p(1-p)/400) = 0.129 sqrt (p(1-p))

Since both obtained same estimate of proportion (that is, value of p), it can be seen that Mathew's estimate will have a small error (That is, 0.129 is smaller than 0.196). This can be attributed to larger sample size although a wider confidence (99%) interval was considered.

SUIVE
Marrrta [24]

Answer:

Step-by-step explanation:

t = tutoring and g = grocery store

t + g = 15......t = 15 - g

15t + 9g = 159

15(15 - g) + 9g = 159

225 - 15g + 9g = 159

-15g + 9g = 159 - 225

-6g = - 66

g = -66/-6

g = 11 <===== 11 hrs worked at the grocery store

t + g = 15

t + 11 = 15

t = 15 - 11

t = 4.....4 hrs tutoring

zysi [14]

Answer:

y=tanx+C

Step-by-step explanation:

\frac{dy}{dx}  =  {sec}^{2}  \: x \\  \\ dy = {sec}^{2}  \: x \: dx \\  integrating \: both \: sides \\  \\  \int \:1\: dy =  \int {sec}^{2}  \: x \: dx \\  \\  \huge \red{ \boxed{ \therefore \: y = tan \: x + c}} \\
