Answer:

2/5

Step-by-step explanation:

Ok there are 4+3+1+2 pairs of socks in all... Aka 10 sock pairs in all.

There are 4 white pairs.  So the probability she selects a white pair is 4/10.

4/10 can be reduced to 2/5.

Answer:
2/5
Explanation:
So the total pairs of socks she has is 10 pairs. So we are trying to find the white socks probability so you would do 4/10. This simplified is 2/5. So that’s how you do it.

Rectangular prism A measures 2 inches by 7 inches by 8 inches. Rectangular prism B measures 1 inches by 5 inches by 10 inches.
satela [25.4K]

The Volume for Rectangular prism A is 172 inches², Volume = 112 inches³

Surface Area to Volume Ratio = 43/28

<h3>Mensuration of Solids</h3>

Given Data

Rectangular prism A

Length = 2 inches

Width = 7 inches

Height = 8 inches

Surface Area

A=2(wl+hl+hw)

A=2(7*2+8*2+8*7)

A=2(14+16+56)

A= 172 inches²

Volume

Volume = L*W*H

Volume = 2*7*8

Volume = 112 inches³

Surface Area to Volume Ratio

= 172/112

= 43/28

The heights of American men are normally distributed. If a random sample of American men is taken and the confidence interval is
solmaris [256]

Answer:

<h2>69.5</h2>

Step-by-step explanation:

Given the confidence interval of the heights of american heights given as (65.3,73.7);

Lower confidence interval L = 65.3 and Upper confidence interval U = 73.7

Sample mean will be the average of both confidence interval . This is expressed mathematically as \overline x = \frac{L+U}{2}

\overline x = \frac{65.3+73.7}{2}\\\overline x = \frac{139}{2}\\\overline x = 69.5

Hence, the sample mean is 69.5
