Answer:
(x + y)^5.
Step-by-step explanation:
The (r+1)th term of (x + y)^n = nCr x^n-r y^r
Compare this with 10x^3 y^2 we get
nCr = 10 , n-r = 3 and r = 2 giving n = 3+2 = 5
5C2 = 10.
So the answer is (x + y)^5.
Answer:
They run at the same speed
Step-by-step explanation:
First, you have to find a way seeing how fast both animals run in the same amount of time. You can find out how fast they both run in one second.
60 feet in 6 seconds is how many feet in one second? Well, you can do 60/6 (60 divided by 6) and you will see that in one second, the cheetah can run 10 feet
100 feet in 10 seconds is how many feet in one second? Same thing, you can do 100/10 (100 divided by 10) and you will see that the gazelle can run 10 feet in one second.
Finally, you compare the two answers from the two animals. For the cheetah, we learned that it can run 10 feet in one second, and for the gazelle, we learned that it can run 10 feet in one second. So, we know that they run at the same speed.

he events are not independent
<h3>How to determine if they are mutually exclusive?</h3>
The given parameters are:
P(A) = 0.2
P(B) = 0.2
The events are mutually exclusive.
So, as have
P(A or B) = P(A) + P(B)
If the events are independent, then
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = P(A) * P(B)
So, we have
P(A and B) = 0.2 + 0.2 - 0.2 - 0.2 = 0
P(A and B) = 0.2 * 0.2 = 0.04
The above equations are not equal
Hence, the events are not independent

Answer:
Step-by-step explanation:
A radius is a segment from the center of the circle to a point on the circle. The center is labeled B, and points on the circle are A, C, D, Y. No segment BY is shown, so that might not be an appropriate choice for a radius.
BA, BC, BD are radii
