One Hundred Thirty-five Million.
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%
75, 76, 80, 83, 84, 85, 89, 91, 94, 94
The median is 84.5
You add the two middle numbers (84, 85) and divide by 2.
3*P + (1/6%* 3p)=
Thats the formula
basically its: 3 * p + 1/6 of 3p
1, when you factor you get 6x(x^2-1)+4(x^2-1)=
