Answer:
−5/8÷9/10= -0.69444444444
Answer:
42 or 48
Step-by-step explanation:
It's a acute angle so it's that one or that one.
Sua matemática seria:10.8 * 3 = 32.4
32.4 + 32.4 + 10.8 + 10.8 = 86.4
86.4 * 130 = 11,232
11,232 - 10,000 = 1,232Você precisará de mais 1,232 tijolos para concluí-lo.

Answer:
a) 0.8841
b) 0.0435
Step-by-step explanation:
A : the set of joints deemed defective by inspector A.
B: the set of joints deemed defective by inspector B.
U: the set of all joints.
The problem says |A|=724, |B|=751, |A∪B|=1159, |U|=10000. Hence, with the help of Venn diagram we can answer the following:
Part a)
This asks for the number of joints that are ∉(A∪B).
hence,
P (∉(A∪B)) :

part b)
This asks for the number of joints that are in B but not in A, which Is represented as the set B−A
