Probability of having at least 1 boy = 1 - the probability of having ALL girls.


P(5 girls) = (1/2)⁵ = 1/32


P(At least 1 boy) = 1 - 1/32 = 31/32


Answer: 31/32

according to the 2000 U.S. Census, 138,053,563 Americans are male, and 143,368,343 Americans are female. About what percent of f
Novosadov [1.4K]

Givens

Male  =      138,053,563

Female =   143,368,343

Total

The total equals 281 421 906

Percents

Male = (138,053,563 / 281 421 906) * 100 = 49.1%

Female = ( 143,368,343/ 281 421 906) * 100 =  50.94%

Rounded

Male =  49

Female = 51

Comment.

To find this %s you could just use the first 3 digits of everything.

Total = 138 + 143 = 281

% male = (138/281) = 49.1

% female = (143/281) * 100 = 50.88

These give you the same answers when rounding.

In one area, the lowest angle of elevation of the sun in winter is 27.5°. Find the minimum distance x that a plant needing full
Alex73 [517]

Answer:

The minimum distance x that a plant needing full sun can be placed from a fence that is 5 feet high is 4.435 ft

Step-by-step explanation:

Here we have the lowest angle of elevation of the sun given as 27.5° and the height of the fence is 5 feet.

We will then find the position to place the plant where the suns rays can get to the base of the plant

Note that the fence is in between the sun and the plant, therefore we have

Height of fence = 5 ft.

Angle of location x from the fence = lowest angle of elevation of the sun, θ

This forms a right angled triangle with the fence as the height and the location of the plant as the base

Therefore, the length of the base is given as

Height × cos θ

= 5 ft × cos 27.5° = 4.435 ft

The plant should be placed at a location x = 4.435 ft from the fence.
