Answer:
A. y + 1 = -2(x – 5)
Step-by-step explanation:
For a line with slope m through point (h, k), the equation is ...
y -k = m(x -h)
Fill in your values of m=-2, h=5, k=-1 and you have ...
y -(-1) = -2(x -5)
y +1 = -2(x -5) . . . . . . simplify. Matches selection A.

Step-by-step explanation:
Answer:
0.50
Step-by-step explanation:
Let A represent the probability that it will be cloudy
Let B represent the probability that it will be rainy
P(A) = 0.40
P(B) = 0.30
P(A and B) = 0.20
For non mutually exclusive events the probability of event A or B is
P(A or B) = P(A) + P(B) - P(A and B)
= 0.40 + 0.30 - 0.20
= 0.50
There is a 50% probability that the picnic will be postponed. Therefore the probability that the picnic will not be postponed is equals 1 - P(A and B)
= 1 - 0.50
= 0.50 or 50%
