C + a = 132.....a = 132 - c
5.10c + 9.60a = 898.20
5.10c + 9.60(132 - c) = 898.20
5.10c + 1267.20 - 9.60c = 898.20
5.10c - 9.60c = 898.20 - 1267.20
-4.50c = - 369
c = -369/-4.50
c = 82 <=== child tickets sold
The answer is 5 units. the top is 10, and x is half of that
Y=3x-9
0=3x-9
-3x=-9
x=3
X-int = 3
Let event A = Caroline buys fruit, event B = Caroline buys CD, Ac and Bc are complementary events.
Events AB, ABc, AcB and AcBc are jointly exhaustive and disjoint, hence P(AB) + P(ABc) + P(AcB) +P(AcBc) =1.
Events A and B independent, hence Ac and Bc independent too and probability P(AcBc) = P(Ac)*P(Bc) = (1 - P(A))(1-P(B)) = 0.6*0.4 = 0.24.
Required probability P(AB + ABc + AcB ) = P(AB) + P(ABc) + P(AcB) = 1- P(AcBc) = 1 - 0.24 = 0.76.
Answer: Probability that Caroline buys fruit, a CD or both is 0.76.
Answer:
fraction of the wall is limestone is 4/22
or 2/11 as a reduced fraction
Step-by-step explanation:
fraction of the wall is limestone is 4/22
the width is 22 in total
10 inches concrete = 10/22
8 inches brick : 8/22
4 inches limestone : 4/22
10/22+8/22+4/22=22/22=1
