B.
Step-by-step explanation:
When reflecting over the x-axis:
(x, y) (x, -y)
The y changes signs (+, -)
Answer:
Step-by-step explanation:
All triangle must have angle values adding up to 180 degrees.First solve for y;
110+33+y=180
y=37 degrees
x is the opposite inverse angle of 33 degrees, it has an angle measure of 33 degrees.
z is equal to 110 degrees because it is opposite to that angle measure because all rhombi have 2 way symmetry.
Answer: 0.4987
Step-by-step explanation:
Given : The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with
Mean : 
Standard deviation : 
Let X be the random variable that represents the weight of randomly selected student .
Z score : 
For x = 5 lbs

For x = 11 lbs

By using the standard normal distribution table , the probability that the weight of the newborn baby boy will be between 5 lbs and 11 lbs :-

Hence, the probability that the weight of the newborn baby boy will be between 5 lbs and 11 lbs =0.4987
