Answer:
D
Step-by-step explanation:
I usually use a z-score table, but you can do this with a calculator.
If we go to a z-score table, we first look up the first two digits (in this case, 2.8) in the far left column. Then we find the hundredths digit in the top row (0.07). Where they intersect is P(z < 2.87).
P(z < 2.87) = 0.9979
Answer D.
Answer:
-6, -1, 4, 9, and 14
Step-by-step explanation:
Just add 5 to each of them
The total amount of money is 75 dollars
There are 5 fifteens in 75
There are 6 dollars saved everytime he makes 15 dollars
6 x 5 = 30
He saved 30 dollars
4x+20+2x+6 is what you get when you distribute, just group the similar ones together and get 6x+26, that's the answer <em><u>6x+26</u></em><em><u /></em><u />
2/7 cup of flour
Simply multiply 2/3 by 3/7 to get
the answer. To multiply 2 fractions together, you multiply the
numerators together and then multiply the denominator together.
2/3 x 3/7 = 6/21
But 6/21 can be expressed in a simpler fashion. Notice that both 6 and
21 can be evenly divided by 3. So divide both the numerator and
denominator by 3
(6/3)/(21/3) = (2)/(7) = 2/7
