Elanso [62]

Answer: 0.0885

Step-by-step explanation:

Given : According to a recent Catalyst Census, 16% of executive officers were women with companies that have company headquarters in the Midwest.

i.e. p= 0.16

Sample size : n= 154

Now, the probability that more than 20% of this sample is comprised of female employees is given by :-

$P(p>0.20)=P(z>\dfrac{0.20-0.16}{\sqrt{\dfrac{0.16(1-0.16)}{154}}})$

[∵ $z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$ ]

$=P(z>1.35)\approx1-P(z\leq1.35)=1-0.9115=0.0885$ [Using the standard z-value table]

Hence, the required probability = 0.0885

5. Aly ordered a pie that had a diameter of 8 in. What is the approximate area of the pie? (Use 3.14 for t)

klasskru [66]

50.24 square inches. If the diameter is 8in, then the radius must be half the diameter, or 4. You can just plug 4 into the formula for the area of a circle [A=pi*radius^2]. When you multiply 3.14 by 4^2, you get 50.24 square inches.

If JAke has 10 white socks, 8 black socks, and 6 gray socks, how many does he need to take out to ensure that he he will get a p

Likurg_2 [28]

$The\ probability\ to\ get\ a\ white\ sock = \frac{10 }{10 + 8 + 6}X\frac{9 }{9 + 8 + 6} = \frac{10}{24}X\frac{9}{23}=\frac{90}{552}\\\\= \frac{ \frac{90}{90} }{ \frac{552}{90} }= \frac{1}{6.13} \\\\it\ means\ that\ Jake\ need\ to\ take\ out\ 7\ socks\ to\ get\ a\ white\ pair\ of\\socks.$
