Ellen has a plastic bag with 3,000 cm^3 of sand, and she wants to put it in a cylindrical bottle that has a height of 15 cm and

a radius of 7 cm.
Will all the sand fit in the bottle?

Yes, because the volume of the bottle is about 6,232 cm^3 more than the volume of the sand.
No, because the volume of the bottle is about 692 cm^3 less than the volume of the sand.
No, because the volume of the bottle is about 2,341 cm^3 less than the volume of the sand.
Yes, because the volume of the bottle is about 1,946 cm^3 more than the volume of the sand.

27.) FEMALE LAWYERS There are 1,094,751 active lawyers living
SOVA2 [1]

Answer:

28.6%; 313,099

Step-by-step explanation:

Lawyers are either male or female, so if 71.4% are male, then 100% minus that are female.

100% - 71.4% = 28.6%

28.6% of 1,094,751 is:

0.286 × 1094751 = 313098.786

Rounded to the nearest whole number, there are 313,099 female lawyers.

A study sampled 350 upperclassmen (Group 1) and 250 underclassmen (Group 2) at high schools around the city of Portland. The stu
iVinArrow [24]

Answer:

-0.061 < P_1 -P_2< 0.025

Step-by-step explanation:

Give data:

n_1 = 350

n_2 =250

x_1 = 23

x_2 = 21

\hat{P} 1 = \frac{x_1}{n_1} = \frac{23}{350} = 0.066

\hat{P} 2 = \frac{x_2}{n_2} = \frac{21}{250} = 0.084

for 95% confidence interval

\alpha = 1 - 0.95 = 0.05 and \alpha/2 = 0.025

z_{\alpha/2} = 1.96  from standard z- table

confidence interval for P_1  and P_2 is

\hat{P} 1 - \hat{P} 2 \pm z_{\alpja/2} \sqrt{\frac{\hat{P} 1(1-\hat{P} 1)}{n_1} +\frac{\hat{P} 2(1-\hat{P} 2)}{n_2}}

(0.066 - 0.084) \pm 1.96 \sqrt{\frac{0.066(1-0.066)}{350} +\frac{0.084(1-0.084)}{250}}

-0.018 \pm 0.043

confidence interval is

-0.018 - 0.043 < P_1 -P_2

-0.061 < P_1 -P_2< 0.025
