Answer:
<h3>x = 18</h3>Step-by-step explanation:
Find the diagram attached
If W and X are the endpoints of a diameter on the circle, this means that arc WX is 180degres
Since the angle at the vertex is half the angle at the intercepted arcs.
<V = 1/2(arcWX)
4x+18 = 1/2*180
4x+18 = 90
4x = 90-18
4x = 72
x = 72/4
x = 18
Hence the value of x is 18

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
