This is tricky but I worked out the answer is A
I got 110 but it might be wrong let me check.
Since it is 100 minutes of stretching and scrimmaging, we can subtract the 10 minutes we know is stretching. 90 minutes is equal to 2/3 of the practice then. Divide by 2 and multiply by 3 to get the entire time of the practice or 135 minutes. However, you asked for it in hours, so we can subtract 120 minutes because this is 2 hours. 15 minutes is 1/4 of an hour. So practice took 2&1/4 hours. Hope that helps.
Answer:
D. 6x^4+3x^3y
Step-by-step explanation:
3x^3(2x+y)
distribute 3x^3
3x^3*2x+3x^3*y
=6x^4+3x^3y
Answer:
The probability that the racket is wood or defective is 0.57.
Step-by-step explanation:
Let W represents wood racket, G represents the graphite racket and D represents the defective racket,
Given,
n(W) = 100,
n(G) = 100,
⇒ Total rackets = 100 + 100 = 200
n(W∩D) = 15,
n(G∩D) = 14,
⇒ n(D) = n(W∩D) + n(G∩D) = 15 + 14 = 29,
We know that,
n(W∪D) = n(W) + n(D) - n(W∩D)
= 100 + 29 - 15
= 100 + 14
= 114,
Hence, the probability that the racket is wood or defective,
