Combined, there are Asians, Africans, Europeans, and Americans in a village. The number of Asians exceeds the number of Afric

yanalaym [24]

There are 123 Asians, 25 Africans, 21 Europeans and 8 Americans in the village.

To determine the number of Asians, Africans, Europeans, and Americans in the village, the following calculation must be performed:

A.S + A.F + E.U + A.M = 177
A.S = A.F + E.U + 69
E.U - A.M = 13
E.U = A.M + 13
2A.F = E.U + A.M + 29
A.F + E.U + 69 + A.F + E.U + A.M = 177
A.F + A.M + 13 + 69 + A.F + A.M + 13 + A.M = 177
2A.F + 3A.M = 177 - 13 - 13 - 69
E.U + A.M + 29 + 3A.M = 82
A.M + 13 + A.M + 29 + 3A.M = 82
5A.M = 82 - 13 - 29
A.M = 40/5
A.M = 8
E.U = 8 + 13 = 21
A.F = (21 + 29) / 2 = 25
A.S = 177 - 25 - 21 - 8 = 123

Therefore, there are 123 Asians, 25 Africans, 21 Europeans and 8 Americans in the village.

A ski jumper is preparing for her start on top of the jumping hill in korea which has a horizontal run of 234 meters. She sees t

slamgirl [31]

Answer:

The height of the jumping hill x = 189.3 m

Step-by-step explanation:

From Δ ABC

AB = x = height of the hill

∠A = 36° , ∠B = 90°

Thus ∠C = 180 - ∠A - ∠B

⇒ ∠C = 180 - 36 - 90

⇒ ∠C = 54°

From Δ ABC

$\sin 54 = \frac{AB}{AC}$

$\sin 54 = \frac{x}{234}$

x = 0.809 × 234

x = 189.3 m

This is the height of the jumping hill.

Suppose a family has three children of different ages. We assume that all combinations of boys and girls are equally likely. (a)

Ivan

Answer:

a) There are 8 possible combinations and each probability is 1/8.

b) The probability that it is a boy given that there are two girls is 3/8

Step-by-step explanation:

a) The sample space is given by:

BBB (3 boys)

BBG (Boy, boy, girl)

BGB (Boy, girl, boy)

BGG (Boy, girl, girl)

GBB (girl, boy, boy)

GBG (girl, boy, girl)

GGB (girl, girl, boy)

GGG (3 girls)

The probability of each combination is the same:

P(BBB)=P(B∩B∩B)= $\frac{1}{2} \frac{1}{2} \frac{1}{2}=\frac{1}{8}$

2) There are three possible combinations in which there are 2 girls and 1 boy:

BGG, GBG, GGB

So the probability is given by:

P(BGG ∪ GBG ∪ GGB)= $\frac{1}{2} \frac{1}{2} \frac{1}{2}+\frac{1}{2} \frac{1}{2} \frac{1}{2}+\frac{1}{2} \frac{1}{2} \frac{1}{2}=\frac{3}{8}$
