Answer: D= 12/37
Step-by-step explanation:
To find sin of angle A, you take the opposite angle over the hypotenuse. 12 is opposite of A and 37is the hypotenuse.
P(s) = 45/125 = 0.360
P(A&C) = 38/125 = 0.304
Probability that one is not in Arts and Crafts = 1- P(A&C) = 1-0.304 = 0.696
Therefore,
Probability that the child selected is in swimming when its known they didn't sign for Arts and craft = Probability they signed for swimming * Probability that they didn't sign for Arts and Crafts = 0.360*0.696 = 0.25056
Answer:
Or, 1/2.
Step-by-step explanation:
To find the slope of a line that crosses any two given points, we can use the slope formula:
Where (x₁, y₁) is our first point, and (x₂, y₂) is our second point.
We will let (6, -7) be our first point (x₁, y₁), and (4, -8) be our second point (x₂, y₂).
Substitute them into the formula. Hence:
Simplify:
Evaluate. Hence, our slope is:
Answer:
equation :
1. b + 5 = 3
2. 3b = - 6
3. 10b = -20
1. b = 3 - 5 = - 2
2. 3b/3 = - 6/3 = - 2
3. 10b / 10 = - 20 / 10 = - 2
