Answer:
b = 23.3
Step-by-step explanation:
First, we need to determine whether this is a right or non-right triangle.
We know that the sum of all the angles in a triangle must add up to 180, so we can add angles A and B and subtract the sum from 180:
The 52 indicates that it is a non-right triangle, so we must rely on either the law of sines or law of cosines to find the measure of b.
Given that we have angle A and its resulting side, a, along with angle B, we can use the law of sines:
What is the inequality sign?!?
Answer:
7/18
Step-by-step explanation:
P(sophomore girl) is 7 out of a total 30.
P(girl) is 18 out of 30.
(7/30) / (18/30) = 7/18
If you just look at the girls column you can see this immediately. A given is that we're looking for a girl (18 girls), then what is the chance that it's a sophomore. That is 7 out of 18.
Answer:
z > -2
Step-by-step explanation:
7 + z > 5
subtract 7 from each side of the equation:
z > -2
