Given:
μ = 89 ng/ml, population mean
σ = 23 ng/ml, population standard deviation
Random variable, x = 100
To test P(x < 100), calculate the z-score.
z = (x-μ)/σ = (100 - 89)/23 = 0.4783
From standard tables, obtain
P(x < 100) = 0.6838 = 68.4%
Answer: 68.4%
4 because 4 times 24 equals 96 then 96 divided by 3 equals 32
X is 1 over 10. 10 squared is 100. X is 7. The third root of 343 is 7.
The area of a trapezoid, A, equals h, the height of the trapezoid, times the length of base one plus the length of base two divided by two.
The perimeter of a trapezoid, P, equals the measure of base one plus the measure of base two plus the measure of leg one plus the measure of leg two
That is as simple as i can make it lol. i hope it helps some
