The mean height of women in a country​ (ages 20minus​29) is 64.2 inches. A random sample of 50 women in this age group is select
Cloud [144]

Answer: 0.0142

Step-by-step explanation:

Given : The mean height of women in a country​ (ages 20 - ​29) is 64.2 inches.

i.e. \mu=64.2

Also, \sigma=2.58

Sample size : n= 50

Let x denotes the height of women.

Then, the probability that the mean height for the sample is greater than 65​ inches :-

P(x>65)=1-P(x\leq 65)\\\\=1-P(\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}\leq\dfrac{65-64.2}{\dfrac{2.58}{\sqrt{50}}})\\\\=1-P(z\leq2.193)\ \ [\because z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=1-0.9858463\ \ [\text{By using z-value table or calculator}]\\\\=0.0141537\approx0.0142

Hence, the the probability that the mean height for the sample is greater than 65​ inches = 0.0142

A cone and 2 cylinders are shown below. The volume of the cone is 15 cubic centimeters. Each of the 2 cylinder has the same heig
shutvik [7]

Answer:

90cm^{3}

Step-by-step explanation:

<u>Given:</u>

The volume of a cylinder =15cm^{3}

Height of cone = Height of either cylinder

Radius of cone=Radius of either cylinder

<u>Formula:</u>

Volume of a cone =\pi r^{2}h/3

Volume of a cylinder =\pi r^{2}h

<u>To find: </u>Combined volume of both cylinders.

The volume of a cylinder =15cm^{3}

\pi r^{2}h/3=15cm^{3}

\pi r^{2}h=15 * 3cm^{3}

\pi r^{2}h=45cm^{3}

[As

Height of cone = Height of either cylinder

Radius of cone=Radius of either cylinder<u>]</u>

\pi r^{2}h=45cm^{3}  is the volume of one cylinder.

Combined volume of cylinder = 2* Volume of cylinder = 2*45 =90cm^{3}
