Answer:
16/29
Step-by-step explanation:
P(A∪B) = P(A) + P(B) - P(A∩B)
P(basketball or baseball) = P(basketball) + P(baseball) - P(both)
= (13/29) + (7/29) - (4/29)
= 16/29
The probability that a randomly chosen student plays either sport is 16/29.
Answer:
The correct answer of the problem is 1.
Step-by-step explanation:
Let the original number on which the wrong procedure is applied is x.
Now, Steve multiplied by 7 and then added 3 to get the answer of - 11.
So, 7x + 3 = - 11
⇒ 7x = - 14
⇒ x = - 2
Now, the correct step to get the answer is multiplying by 3 and adding 7.
Hence, the correct answer of the problem is (- 2) × 3 + 7 = - 6 + 7 = 1 (Answer)
Answer:
No
Step-by-step explanation:
We can't use 2x + c = d for solving 2x + 1 = 9 . Here we can find the value of x from 2x + 1 = 9.
Putting the value of x in 2x + c = d :-
But still we don't know the exact value of c & d . If in the question at least we could have got one exact value of either c or d , then we could find out the value of other variable.

Answer:
51
Step-by-step explanation:
Your score total must be 3×75 = 225. Subtracting the two high scores gives ...
225 -95 -79 = 51
__
The score of 34 is below that value, so it is the one that will be dropped.
You need a test score of 51 on the next test for your average to be 75.
