Step-by-step explanation:
So sqrt(40) lies between 6 and 7.
Answer:
only A
Step-by-step explanation:
A is correct because if a number is less than 7, the number under the square root will be negative, and that will yield an imaginary (or non-real number)
B is incorrect because even if you choose a number less than 7, the result will still yield a real number
C is incorrect due to the same logic as B
D is incorrect because you can take the cube root of a negative number without it being non-real.
Answer:
C=43.98
Step-by-step explanation:
C=2piR
R=d/2
R=7
C=14pi=43.98
Answer:
18/25 = 72%
Step-by-step explanation:
P(B ∪ F) = P(B) + P(F) - P(B ∩ F)
= 12/25 + 11/25 - 5/25
= 18/25
The probability a randomly chosen student plays either sport is 18/25 = 72%.
