180 but i dont know if thats exactly right my friend
just told me so its probably not even right
Without answer choices, equivalent expression could be (5x12)+36 or 6(6+10). For the first one you multiply using order of operations meaning you complete the parenthesis first, 5 multiplied by 12 is 60 and you add 36 to get the same answer as the actual equation for the second equation I used factoring to bring it together meaning if you multiply 6 by 6 it is 36 and if you multiply 6 by 10 you have 60 making it 36+60 and equivalent to the actual question.
Answer:
The 99% confidence interval for the true mean number of hours a union member is absent per month is (0 hours, 16.5125 hours).
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which s is the standard deviation of the sample.
So
The lower end of the interval is the mean subtracted by M. So it is 7.5 - 9.0125 = -...
There is not a negative number of hours. So the lower end of the interval is 0 hours.
The upper end of the interval is the mean added to M. So it is 7.5 + 9.0125 = 16.5125 hours.
The 99% confidence interval for the true mean number of hours a union member is absent per month is (0 hours, 16.5125 hours).

Answer:
Step-by-step explanation:
After 3 hours, Spike charges 6 dollars per hour. For 3 hours, the charge is only $5×3 = $15 (which is $3 less than $6×3). So the rate after 3 hours can be modeled by ...
s(h) = 6h -3
For 8 hours, s(8) = 6·8 -3 = 45 . . . . dollars
__
After 4 hours, Main Deck charges 8 dollars per hour. For 4 hours, the charge is only $18 (which is $14 less than $8×4). So the rate after 4 hours can be modeled by ...
m(h) = 8h -14
For 8 hours, m(8) = 8·8 -14 = 50 . . . . dollars
__
For 8 hours, the $45 charge at Spike's is $5 less than the $50 charge at Main Deck.
