Answer:
159 degrees
Step-by-step explanation:
A full semicircle (or half circle) has a degrees of 180. And x is equal that semicircle so x = 180, now if we subtract 21 from 180 we get 159, so X = 159.
Answer:
hi
Step-by-step explanation:
Let's first denote:
F - a favorable response
F' - an unfavorable response
S - successful
We know that:

So, from the conditional probability, we can calculate:

Answer E.
You have $12, and need at least x more dollars to spend $30 total. So the inequality is 12 + x ≥ 30, where x is the number of dollars needed to get free delivery. To solve for x, subtract 12 from each side of the sign. x ≥ 30 - 12, x ≥ 18. You must spend at least 18 more dollars to qualify for free delivery.
