Answer:
rate: 4 rate: -2
starting: 3 starting: 30
y= -4x + 3 y= -2x + 30
rate: 2 rate: 6
starting: -4 starting: 6
y= 2x -4 y= 6x + 6
Step-by-step explanation:
^equation to find slope
To also find b, the starting value, you need to take any point given and substitute it back into the equation with the slope.
However, these problems give you the y-int already [it is the point like (0,y)]
7-3/1-0 = 4/1
rate: 4
starting: 3
y= 4x + 3
28-30/1-0= -2/1
rate: -2
starting: 30
y= -2x + 30
-2 - (-4)/1-0 = 2/1
rate: 2
starting: -4
y= 2x -4
6-0/1-0 = 6/1
rate: 6
starting: 6
y= 6x + 6

Answer:
Probability = 0.1587
Step-by-step explanation:
The provided information is:
Let X be the scores of the IQ test for adults that is normally distributed with mean = 100 and standard deviation
= 15.
Also, US military has minimum IQ score of 85.
Thus, the probability that randomly selected adult does not meet US military enlistment standards is:
The probability can also be written as:
Thus,
Using the Normal probability table probability of Z = -1 is 0.1587
Thus, the required probability is 0.1587
