Here is your fake answer:

Note that for each line in a triangle, the angle opposite of it would be the same in how large the angle is. Therefore, the longer the opposite side, the greater the angle measurement. The shorter the opposite side, the smaller the angle measurement.

∴ In the order of smallest to largest:

CA = 8; m∠B = 8

BC = 12; m∠A = 12

AB = 15; m∠C = 15

∴ ∠B , ∠A , ∠C , or (C) is your answer

The heights of young women aged 20 to 29 follow approximately the N(64, 2.7) distribution. Young men the same age have heights d
murzikaleks [220]

Answer: 10.703%

Step-by-step explanation:

Let minimum height of the tallest 25% of young women be M.

Let Q be the random variable which denotes the height of young women.

Therefore, Q – N(64,2.70)

Now, P(Q˂M) = 1-0.25

i.e. P[(Q-64)/2.7 ˂ (M-64)/2.7] = 0.75

I.e. ф-1 [(M-64)/2.7] = 0.75 i.e. (M-64)/2.7 = ф-1 (0.75) = 0.675 i.e. M = 65.8198 inches

Let R be the random variable denoting the height of young men

Therefore, R – N (69.3, 2.8)

i.e. (R-69.3)/2.8 – N(0,1)

therefore the probability required = P(R ˂65.8198) = P[(R-69.3)/2.8 ˂ (65.8198 – 69.3)/2.8]

this gives P[(R-69.3)/2.8 ˂] = ф (-1.2429) = 0.107033

From this, the percentage of young men shorter than the shortest amongst the tallest 25% of young women is 10.703%

So all the numbers added together is 12 so then divide 12 and 6

the mean would be 6
