Answer:
thats 8 with the power of three or a fraction of 3 and if your subtracting 8 the so called "hidden" number is 8 meaning that it would equal 0
Step-by-step explanation:
7.
10% = 6
25% = 15
50% = 30
20% = 12
_____________________
8.
a = 35
b = 105
c = 140
____________________________
9.
15 is 30% of 50.
_____________________________
10.
The punch recipe contains 25% lemonade:
24/6 = x/100
x=1/4 x 100 = 25%

520
multiply 650 by 80 amd then divide by 100
or simply multiply 650 by 0.8
to get 520 students.

Number of items checked = 300
Defective items = 3%
Number of defective items =
Number of defective items =
Number of defective items = 9
Number of items worked = Total items - Number of defective items
Number of items worked = 300 - 9 = 291
291 items of checked items worked.
We would have the following sample space:
(1, 1), (1, 2), (1, 3), (1, 4)
(2, 1), (2, 2), (2, 3), (2, 4)
(3, 1), (3, 2), (3, 3), (3, 4)
(4, 1), (4, 2), (4, 3), (4, 4)
Those give us these sums:
2, 3, 4, 5
3, 4, 5, 6
4, 5, 6, 7
5, 6, 7, 8
P(sum of 2) = 1/16 =0.0625
P(sum of 3) = 2/16 = 0.125
P(sum of 4) = 3/16 = 0.1875
P(sum of 5) = 4/16 = 0.25
P(sum of 6) = 3/16 = 0.1875
P(sum of 7) = 2/16 = 0.125
P(sum of 8) = 1/16 = 0.0625
<span>a = 1/2 x b x h
h = 3b
so 1/2 x b x 3b = (1/2)(3b^2) = 150
(150 x 2)/3 = b^2
100 = b^2
b = square root of 100 = 10
h = 3b = 3 x 10 = 30</span>
