Answer:
x = 2
Step-by-step explanation:
For secants that intersect at an external point, the product of the external length and total length is a constant.
... 3·(3 +5) = 4·(4 +x) . . . . . write the two products, and set them equal
... 24 = 16 +4x . . . . . . . . . . eliminate parentheses
... 8 = 4x . . . . . . . . . . . . . . .subtract 16
... 2 = x . . . . . . . . . . . . . . . . divide by 4
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.
