Answer:
0.002
Step-by-step explanation:
We need to estimate the standard error of the mean, so we can use it as a standard deviation of the sample of 50 males.
Standard error of the mean = standard deviation/√n
Standard error of the mean = 32/√50 = 4.52
Now we can use this Standard error of the mean to estimate z as follows:
Z = (x – mean)/standard deviation
Z = (190-177)/4.52
Z = 2.87
Using a Z table we can find probability that mean is under 190
P (z<190)= 0.998
For the probability that the mean exceed 190 lbs we substract from 1
P(z>190) = 1 - 0.998 = 0.002
Answer:
4
4z+4
Divide each term of 4z+4 by 4 to get 1+z.
1+z
Answer:
d + .09d
Step-by-step explanation:
9% of his salary can be found by multiplying d by 0.09. Then simply add that to his original salary to get you answer.

We must first find the slope.
<em>Please refer to my Answer from this Questions to know more about Slopes of a Line:</em>
We can see the marked points,
and
, are on the line.
Solving for the slope:

Now we can now solve for the
-intercept.
