The symbols used in question 3 are saying your x values can be anything, as long as x is larger than 0, so all the positive numbers
Try A I believe that’s right
Answer:
g(5x)= 20
Step-by-step explanation:
g(x)=4 is basically saying that 1 x is equal to 4.
g(5x) wants to know what 5 times 1 x is equal to (5 times 4 (4 is equal to 1 x)
g(5x)= 5(x=4)
g(5x)= 20
P(X<=x) = 1 + 5.486 = 6.486
The z-score of the information given is,
z = (x - µ )/ σ
Where,
µ = mean
σ = standard deviation
From the information given,
x = 3.71
µ = 86
σ = √225 = 15
hence,
z = (3.71 - 86)/15 = -5.486
thus,
P(X<=x) = 1 + 5.486 = 6.486
hence , P(X<=x) = 1 + 5.486 = 6.486
