You need x 20 to get to 10000, so do the same with 150 and get 3000, so it is 3000/10000
You're looking for a value

such that

Because the distribution is symmetric, the value of

in either case will be the same.
Now, because the distribution is continuous, you have that

The mean for the standard normal distribution is

, and because the distribution is symmetric about its mean, it follows that

.

You can consult a

score table to find the corresponding score for this probability. It turns out to be

.

Each day she must stay at 10 or more.
Step-by-step explanation:
In the drawing, put from Monday to Sunday, choose a value between 10 and 15 for each day and represent it.
Answer:
Slope=14.000/2.000=7.000
x-intercept = 300/-7 = -42.85714
y-intercept = 300/1 = 300.00000
