First, find the lowest common denominator. That is 12. You only have to change 3/4 into 12ths.
3/4 = 9/12
11/12 – 9/12 = 2/12 = 1/6
Step-by-step explanation:
20%=cows 0.4(40%)=goat 40%=sheep
if 40%sheep=40 sheeps
20% cow=x
20%×40=40%×x
8=40%x
x=8/40%
x=20
..so there are 20 cows
sorry...not sure
I think... 1500
Step-by-step explanation:
multiply 30 and 25 then times 750 as your answer by 2 to get 1500
P(Y > 121) = 1 - P(Y < 121) = 1 - P(z < (121 - 115)/6) = 1 - P(z < 1) = 1 - 0.84134 = 0.15866
P(Y ≤ c) = 0.15
P(Y ≤ c) = 1 - 0.85
P(Y ≤ c) = 1 - P(z ≤ 1.0365)
P(Y ≤ c) = P(z ≤ -1.0365)
Thus, (c - 115) / 6 = -1.0365
c - 115 = -6.219
c = -6.219 + 115
c = 108.781
