A normal distribution has a mean of 10 and a standard deviation of 1. What is the probability of selecting a number that is at m
Len [333]

Answer: 0.500

Step-by-step explanation:

Given : A normal distribution has a mean(\mu) of 10 and a standard deviation(\sigma) of 1.

Let x be a random variable that represents numbers .

The probability of selecting a number that is at most 10 will be

P(x\leq10)=P(\dfrac{x-\mu}{\sigma}\leq\dfrac{10-10}{1})\\\\=P(z\leq0)=0.500

As the area occupied by standard normal curve less than equal to 0 = 0.500

So, required probability = 0.500

If triangle VWZ is congruent to triangle XWY, find the length of YX.
valkas [14]

Answer:

Measure of side YX is 22 units.

Step-by-step explanation:

Since ΔVWZ ~ ΔXWY, their corresponding sides will be in the same ratio.

\frac{VW}{XW}=\frac{VZ}{XY}=\frac{WZ}{WY}

By substituting the values given in the picture in the ratio,

\frac{45}{30}=\frac{(3x-9)}{(x+8)}=\frac{36}{24}

\frac{(3x-9)}{(x+8)}=\frac{3}{2}

By cross multiplication,

2(3x - 9) = 3(x + 8)

6x - 18 = 3x + 24

(6x -18) + 18 = 3x + 24 + 18

6x - 3x = (3x + 42) - 3x

6x - 3x = 42

3x = 42

x = \frac{42}{3}

x = 14

m(YX) = x + 8

          = 14 + 8

          = 22

Therefore, measure of side YX is 22 units.
