Answer: 0.500
Step-by-step explanation:
Given : A normal distribution has a mean of 10 and a standard deviation
of 1.
Let x be a random variable that represents numbers .
The probability of selecting a number that is at most 10 will be
As the area occupied by standard normal curve less than equal to 0 = 0.500
So, required probability = 0.500
Answer:
Measure of side YX is 22 units.
Step-by-step explanation:
Since ΔVWZ ~ ΔXWY, their corresponding sides will be in the same ratio.
By substituting the values given in the picture in the ratio,
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 =
x = 14
m(YX) = x + 8
= 14 + 8
= 22
Therefore, measure of side YX is 22 units.
