Answer:
There will be 31,304 trays of cookies in 43 days.
Step-by-step explanation:
728 = 1 day
728 x 43 = 31,304
To find percent, you take 91 and divide it by 99.2 then multiply by 100.
(91/99.2) × 100 = 91.92%
The probability of 3 failures or less is about 0.83886, so that is the probability the machine will be working.
I ain’t never seen two pretty best friends
3(x + 7) = 9(x - 1)
3(x) + 3(7) = 9(x) - 9(1)
3x + 21 = 9x - 9
<u>- 3x - 3x </u>
21 = 3x - 9
<u>+ 9 + 9</u>
<u>30</u> = <u>3x</u>
3 3
10 = x
