Answer:
3x^2+17x-28+-1x^2/4
Step-by-step explanation:
1.Distribute
3x(x+7)−4(x+7)−1⋅1/4⋅x^2
3x^2+21x−4(x+7)−1⋅ 1/4 ⋅x^2
3x^2+21x−4x-28−1⋅1/4⋅x^2
2.Combine like terms
3x^2+17x−28−1⋅1/4⋅x^2
3.Multiply the numbers
3x^2+17x−28−1/4x^2
4.Combine multiplied terms into a single fraction
3x^2+17x−28+-1x^2/4
SOLUTION
3x^2+17x-28+-1x^2/4

Find the measure of arc BC
Answer:
P(A)=0.55
P(A and B)=P(A∩B)=0.1265
P(A or B)=P(A∪B)=0.7635
P(A|B)=0.3721
Step-by-step explanation:
P(A')=0.45
P(A)=1-0.45=0.55
P(B∩A)=?
P(B|A)=0.23
P(B|A)=(P(A∩B))/P(A)
0.23=(P(A∩B))/0.55
P(A∩B)=0.23×0.55=0.1265
P(A∪B)=P(A)+P(B)-P(A∩B)
=0.55+0.34-0.1265
=0.7635
P(A|B)=[P(A∩B)]/P(B)=0.1265/0.34 ≈0.3721
