Answer:
0.85083 ; 0.83147 ; 0.6823 ; 0.015386
Step-by-step explanation:
Given that:
σ = 25
μ = 86
(a) x is more than 60
P(x > 60)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (60 - 86) /25
Z = - 1.04
P(Z > - 1.04) = 0.85083 (Z probability calculator)
(b) x is less than 110
P(x < 110)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (110 - 86) /25
Z = 0.96
P(Z < 0.96) = 0.83147 (Z probability calculator)
(c) x is between 60 and 110
P(x < 110) - P(x < 60)
P(Z < 0.96) - P(Z < - 1.04)
0.83147 - 0.14917
= 0.6823
(d) x is greater than 140
P(x > 140)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (140 - 86) /25
Z = 2.16
P(Z > 2.16) = 0.015386 (Z probability calculator)
The answer is B, 240 is divisible by 3,4,5 and 8.

do you have pictures and more measurements so i can solve the problem for you?
Step-by-step explanation:
Answer:
A. +$2
Step-by-step explanation:
He gained two dollars when he sold the entire bag of oranges, so he profited +$2.
Simplify the expression first by the "flip and multiply" method. We end up first with:
[x(x-3)]/[x⁻¹(x+4)]
Simplifying further we have:
[x²(x-3)]/(x+4)
Solving for restriction we equate the denominator to 0:
x + 4 = 0
x = -4
x≠4 (-4 is a restriction of the expression)
