Given:
μ = 70, the mean
σ = 10, the standard deviation
The random variable is x = 65.
Calculate the z-score.
z = (x - μ)/σ = (65 -70)/10 = - 0.5
From standard ables, obtain
P(x<5) = 0.3085 ≈ 30%
The score of 65 is in the 30th percentile.
Answer: 30th
I believe that x=20 from the math i did hopefully its helpful.
Answer:
Step-by-step explanation:
(40,5) and (0,0) are points on the line.
Slope of line = (40 miles)/(5 minutes) = 8 Mikes per minute
Answer:
A
Step-by-step explanation:
Because each value of x maps onto only one value of y, it is a function.
However, because it is not the graph of a line, it is a nonlinear function.
Let number be x
2x - 5 = 3
2x = 3 + 5
x = 8 / 2
= 4
The number is 4
