Answer:
The probability is 0.8944
Step-by-step explanation:
The probability of Z<1.25 in a normal distribution is
P(Z<1.25) = 0.5 + P(Z<1.25)
P(Z<1.25) = 0.5 + 0.3944
P(Z<1.25) = 0.8944
Hence, the probability of randomly selecting a z-score less than z = 1.25 from a normal distribution is 0.8944
Answer: The width is 
+ 1x -4
Step-by-step explanation:
We know to find the perimeter we have to add the distance around the rectangle.The distance can also be sought as 2 times the length plus times the width.
So as a formula is like P = 2l + 2w where P is the perimeter.
We are given the perimeter so we can plot it into the formula and also plot in the length because it says the length is 3x -1
+8x - 10 = 2(3x -1) + 2w Now we have to solve for w .Break it down
( + 8x -10) = (6x -2 )+ 2w subtract 6x - 2 from both sides
( + 8x -10) - (6x -2) = 2w
( + 2x -8) = 2w now divide both sides by 2
One the left side factor the numerator
= w Now multiply both sides by 2
w =( + 1x-4 )
The width is x^2 + 1x -4
