Answer:
The correct answer is - C. 24.1%
Step-by-step explanation:
Given:
mean μ = 65%
standard deviation δ = 7.1 %
solution:
Prob( X>70) = 1 - Prob(x<70)
= P (x-μ/δ ≥ 70 -65/7.1)
= 1 - Prob( (70-65)/7.1)
= 1 - Prob ( z < 0.7042553)
= 0.24065
the percentage of students scoring 70 or more in the exam
= 24.065*100
= 24.1%

Answer:
228 kilometers away
Step-by-step explanation:
Irrational, because if you simplify the root V72=6V2
Answer: 10
Step-by-step explanation:
My answer is correct because, if x=5 then were just multiplying 2 times 5 since 5 is not on the top like 
because if it was that means we have to multiply 2 by itself 5 times. But since its not a exponent you just multiply 2 times 5. And 2 x 5= 10.
Hope This Helps!
