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
Answer:
2x - 6 ≥ 6(x-2) + 8
2x - 6 ≥ 6x - 12 + 8
6x - 2x ≤ - 6 + 4
4x ≤ -2
4x/4 ≤ -2/4
x ≤ -1/2
Interval Notation: (- ∞, -1/2]
The line starts from -1/2 with the arrow going to the left (decreasing). The endpoint or value from where it started, which is -1/2, should be shaded. The inequality symbol x ≤ -1/2 represents the values at most or maximum -1/2.

Answer:
The snail will travel 11.75 ft in 5 minutes.
Rule= S(t) = 2.35 t
Explanation:
Since the snail is moving at 2.35 ft per minute, all you have to do is multiply 2.35 by 5 and that's how you get 11.75.
The Rule is the equation that could be used to solve the problem. S represents the snail, and t is how much time the snail travels. To solve from the rule, all you have to do is replace the t in the parenthesis and at the end with a 5 to represent the 5 minutes the snail travels.
Hope this makes sense to you.
