Answer:
hope this helps you out good luck
Given:
z = (x - μ)/σ = z value
x = independent variable = 11
μ = mean = 8
σ = standard deviation = 3
Solution:
X ~ N (8, 3)
For day 1, n = 5
P (X < = 11) = P (Z < = 11 – 8 / 3/Sqrt5) = P (Z <
=2.23) = 0.987126
For day 1, n = 6
P (X < = 11) = P (Z < = 11 – 8 / 3/sqrt6) = P (Z <
=2.45) = 0.992857
For both days:
P (X <= 11) = P (X <= 11) = (0.987126) (0.992857) =
0.9801
Answer:
125,000
Step-by-step explanation:
Multiply 500 by 2.50
The average rate of change is just change in y divided by change in x.
(f(4)-f(-1))/(4--1)
(16-8-4-1-2+4)/5
5/5
1
So the average rate of change is just 1.
The perpendicular line to "Y = -4x + 10" that goes the the point (4,-6) is Y = 1/4x + 5.
The slopes are usually a fraction and a whole number. If the first slope is a whole number, it changes to a fraction, and vice versa. Also, if the first slope is negative, the perpendicular slope is positive and vice versa.
The y intercepts in this case are 10 (first slope) and 5 (dividing by 2) since it has to go through (4,-6). See graph below.
