A random variable x is normally distributed with a mean of 100 and a variance of 25. Given that x = 110, its corresponding z- score is 0.40.
Answer: The given z-score is false.
Explanation: We are given:
Mean,
,
Variance, 



The z-score formula is given below:




Therefore, the z-score corresponding x=100 is 2
Therefore, the given z-score = 0.4 is false.
Answer:
y-int = 2 lbs and slope = 1/2
Step-by-step explanation:
Find where the line meets the y-axis to find your y-intercept.
Find 2 points on the line and use the slope formula (change in y/change in x or rise/run). I used (0,2) and (4,4).
(4-2)/(4-0) = 2/4 which simplifies to 1/2
You can reduce the first one by combining the ab and the ba term
182 would be the correct answer
