Answer:
13 / 19
Step-by-step explanation:
Given that :
U = 130
Let :
s = swimming pool
t = track
g = gym
n(g) = 61 ; n(s) = 68 ; n(t) = 60
n(g n s) = 25 ; n(t n s) = 30 ; n(g n t) = 19
n(g n s n t) = 6
n(g n t) only = n(g n t) - n(g n s n t) = 19 - 6 = 13
Hence, probability that a randomly scted person uses the gym and track and does not use the swimming pool = n(g n t) only ÷ n(g n t)
= 13 / 19
= 13 / 19
Answer:
blue = 4
red = 8
green = 2
yellow = .75 or 3/4
Step-by-step explanation:
4 X 4 X 4 X 4 = 256
8 X 8 = 64
2 X 2 X 2 X 2 = 16
.75 X .75 = .5625 or 9/16
It <span> looks like the first thing you have to find is their GCF, ya reckon ?</span>
The factors of 56 are 1, 2, 4, 7, 8, 13, 28, and 56 .
The factors of 64 are 1, 2, 4, 8, 16, 32, and 64 .
The common factors are 1, 2, 4, and 8 .
The greatest one is 8 .
56/8 = 7
64/8 = 8
56 plus 64 = (8 times 7) plus (8 times 8)
<span>56 plus 64 = </span>8 times (7 plus 8)<span> <== that's the answer</span>
Check it out:
<span>56 plus 64 = </span>120
<span>8 times (7 plus 8) = 8 times 15 = </span><span>120</span>
Answer:
The answer is 20
Step-by-step explanation:
The baby gains 3.25lbs in the last 4 months.
This problem can be solved by simple subtraction. Take the total amount and subtract the 4 month increments in order to find the find 4 months.
Total = 1st 4 months + 2nd 4 months + 3rd 4 months
11 = 4.25 + 3.5 + 3rd 4 months
11 = 7.75 + 3rd 4 months
3.25 = 3rd 4 months
