I think the answer would be 28 because you wold first subtract 90 from 33 then minus 1 which would give you 56 then divide by two to get a final answer of 28
Answer:
12.3 grams
Step-by-step explanation:
When a constant value is added to each data element in a distribution, the maen changes by that constant but the standard deviation stays the same. This is because the standard deviation is a measure of how distant the data are from the mean. When a constant value is added to each of them, the mean also gets the increment. Hence, the distance from the mean is maintained.
However, if the data were multiplied by a constant factor, then the standard deviation will be multiplied by the same factor as well as the mean.
Therefore, the standard deviation from the question remains the same as before, 12.3 grams.
Combination Formula: (n = distinct objects, r = how many you pick) n!/(r!(n-r)!
So n = 7, r = 5
n! = 7! = 5040
R! = 5! = 120
(n-r) = 2! = 2
120*2=240
5040/240 = 21
21 combinations!
Answer:
128 tons can be processed in 8 hours.
Step-by-step explanation:
48 divided by 3 = 16 (to see how much tons are produced in 1 hr.)
16 x 8
=128
Answer:
8.8
Step-by-step explanation:
set up a system
let x be sour keys and y be chocolate bars
2.65=15x+2y
3.35=10x+3y
then solve
X turns out to be 0.05
y turns out to be 0.95
multiply : 24*0.05=1.2
multiply : 0.95*8=7.6
add : 1.2+7.6 = 8.8
