2 answers:
Answer:
a) or 250 * 0.12.
b) 30 photos.
Step-by-step explanation:
Given : Olaf has 250 files saved on an external hard drive. Of those files, 12% are photos.
To find : (a)Write a percent equation to find the number of files that are photos. (b) How many photos does Olaf have saved on his external hard drive.
Solution : We have given total files = 250 .
12% are photos.
a) Percent equation of number of files that are photos = .
⇒ 250 * 0.12
b) Total photos in files = 250 * 0.12 = 30 .
Therefore, a) or 250 * 0.12.
b) 30 photos.

First, isolate y on one side to find some information about the graph.
3x+4y=-10
4y=-10-3x
y=(-10-3x)/4
Now find out the x and y intercepts of this equation;
(0)=(-10-3x)/4
4x0=-10-3x
0=-10-3x
3x=-10
x=-10/3 or -3.3333 (x-intercept)
y=(-10-3(0))/4
4y=-10
y=-10/4 or -5/2 = -2.5 (y-intercept)
Plot these points onto your graph and connect the lines.
I have attached a graph below, I'm sorry I couldn't do it on paper.
Hope I helped :)

Answer:
(a) Minimum red blood cells 5.744 million cells per micro liter
(b) Maximum red blood cells 5.068 million cells per micro liter.
Step-by-step explanation:
Z-score formula is =
Z-score =
The value of z-score is 0.61 so then x will be;
x = 5.744
The minimum red blood cells count that can in top is 27% of count which is 5.744 million cells per micro liter.
Z-score =
The value of z-score is 0.14 so then x will be;
x = 5.068
The maximum red blood cells count that can be in top is 14% of count which is 5.068 million cells per micro liter.
