Answer:
f(g(-1)) = 22
g(f(-1))=6
Step-by-step explanation:
We are given

We need to find f(g(-1)) and g(f(-1))
Finding f(g(-1))
First we will find f(g(x)) i.e

Now finding f(g(-1)) by putting x=-1

So, f(g(-1)) = 22
Finding g(f(-1))
First we will find g(f(x)) i.e

Now finding g(f(-1)) by putting x=-1

So, g(f(-1))=6
If A - B = {2,4,6}, B - A = {0,1,3}, and A∪B = {0,1,2,3,4,5,6,7,8}. What is A∩B?

Answer:
{5,7,8}
Step-by-step explanation:
A-B = {2,4,6} => A={2,4,6}
B - A = {0,1,3} => B= {0,1,3}
A∪B = {0,1,2,3,4,5,6,7,8}
=> A = {2,4,5,6,7,8}
B= {0,1,3,5,7,8}
=> A∩B = {5,7,8}
Answer:
0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine
Step-by-step explanation:
(a) What is the probability that a randomly chosen doctor is in favor of the vaccine
75% of 115/250 = 0.46(German).
60% of 65/250 = 0.26(French).
65% of 70/250 = 0.28(Englishmen). So

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

Answer:
6.3 × 10⁶ square miles
Step-by-step explanation:
We are given,
The radius of the moon is approximately 1000 miles.
We know that the moon resembles a sphere and also,
Area of sphere =
, where r is the radius.
Now, the area of the moon =
= 1.26 × 10⁷ square miles
Since, only the half of the area is clear to view.
So, the area left to view =
= 6.3 × 10⁶ square miles.
Hence, the area of the moon in view is 6.3 × 10⁶ square miles.
