180 = x + x+2 + x+1
180=3x+3
177= 3x
x = 59
Angle A = 59 +2 = 61 degrees
Answer:
x=3
Step-by-step explanation:
2x^2= 18
divide the two by 18 —- x^2=9
now x *x= 9 or the square root of 9

Answer: 0.6827
Step-by-step explanation:
Given : Mean IQ score : 
Standard deviation : 
We assume that adults have IQ scores that are normally distributed .
Let x be the random variable that represents the IQ score of adults .
z-score : 
For x= 90

For x= 120

By using the standard normal distribution table , we have
The p-value : 

Hence, the probability that a randomly selected adult has an IQ between 90 and 120 =0.6827
