Just the first one, r is 4x+2, and h is 5x+4, plug them into the formula pls
Hi there,
I’m attaching the same image with more information on the graph.
The 4th mark (the middle dashed line) is marking the mean (70).
The 3rd and the 5th are marking the mean less/plus 1 deviation.
So, 70.5 is the 5th mark.
Taking this into account:
The probability of selecting a container that has less than 70.5 is 0.1% + 2.2% +13.6% 34.1% + 34.1% = 84.1%
The probability of choosing more than 70,5 = 13.6% + 2.2% +0.1% = 15.9%
Good Luck!
Answer:
Mr. Li
Step-by-step explanation:
$447.75 is 4.5% of $9,950 - Mr. Li earns a 4.5% commission
$453.20 is 4.4% of $10300 - Ms. Brown earns a 4.4% commission
If he sells 34 books and he makes a dollar more for each book he sells, that is 34$ you should add to your total. 45 + 34 = 79
Scott earned 79$ in a week.
