Answer:
(C)Yes, because P(M) ∙ P(N) = P(M ∩ N)
Step-by-step explanation:
Two events A and B are independent if P(A)P(B)=P(A ∩ B)
Given events A and B such that:
P(A) = 0.3, P(B) = 0.25, P(A ∪ B) = 0.425, and P(A ∩ B) = 0.075
- P(A)P(B)=0.3 X 0.25 =0.075
- P(A ∩ B) = 0.075
Since the two expression above gives the same answer, they are independent.
<u>The correct option is C.</u>
Let x be the entire portion of the money Becca needs to save to buy a new tennis racket.
So, 0.25x=$21
x=$21/0.25
x=$84
Thus, the total amount she needs to save is $84. Now, we'll deduct 25 from 84 to get the 75 percent or the remaining amount she has to save.
$84-$21=$63
The answer is $63.
Answer:
Upstream - 2 miles per hour
Downstream - 3 miles per hour
Step-by-step explanation:
For the speed upstream, the answer would be 2 miles per hour (mph), because 6÷3=2.
For the speed downstream, the answer would be 3 miles per hour (mph), because 6÷2=3.
Both answers come in similar methods. Hope this helps you!

Answer:
Step-by-step explanation:
36 d²-36 d+9=9(4d²+4d+1)
=9[4d²+2d+2d+1]
=9[2d(2d+1)+1(2d+1)]
=9(2d+1)(2d+1)
=9(2d+1)²
=[3(2d+1)]²
=(6d+6)²
length=6d+6
perimeter=4(6d+6)=24d+24
when d=2
length=6×2+6=18in
perimeter=4×18=72 in
area=18²=324 in²
