Answer:
0.659 is the probability that a tutor charges between $10 and $20 per hour.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $15 per hour
Standard Deviation, σ = $5.25 per hour
We are given that the distribution of tutoring prices is a bell shaped distribution that is a normal distribution.
Formula:
P( tutor charges between $10 and $20 per hour)
0.659 is the probability that a tutor charges between $10 and $20 per hour.
If you're adding positive numbers together, then the order in which you write or group the addends doesn't matter.
If you're "adding" a negative number to a positive number, it's a little easier to visualize this problem if you write the positive number first, followed by the negative number.
But if you're "adding" -15 to 8, it'd make sense to write the -15 first (because its magnitude is greater) and then the 8: -15 + 8 = -7
Answer:
Hi! This is the answer for part C, or finding the factors.
Step-by-step explanation:
Checked by my teacher. hope this part helps. Will post the rest soon.
Answer:
The answer is C) y - 2 = -5/7(x - 6)
Step-by-step explanation:
Since we have the slope (-5/7) and a point (6, 2), we can just input those in for m and (x1, y1) in point-slope form.
y - y1 = m(x - x1)
y - 2 = -5/7(x - 6)
