Answer:
Yes
Step-by-step explanation:
90 minutes each - 360 ÷ 4
Answer:
C. 95%
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 1189 points, standard deviation of 397 points.
Percentage between 395 and 1983 points?
395 = 1189 - 2*397
1983 = 1189 + 2*397
So within 2 standard deviations of the mean, which by the Empirical Rule is approximately 95%, and the answer is option C.
Answer:
Part A: 2D + 3 = A
Note: I have likely given you the answer to the whole problem. See below.
Step-by-step explanation:
Givens
- Alan = A
- Bruce = B
- Cecil = C
- Dylan = D
Comment
You have to pay the most attention to Alan and Bruce. Once you have equations for those two. Cecil's weight is just the sum of those two.
<em>Alan</em>
Alan = Twice*Dylan + 3 or
A = 2*D + 3
<em>Bruce</em>
Bruce = three * Dylan - 12
B = 3*D - 12
<em>Cecil</em>
Cecil = Alan + Bruce
C = A + B
Note
The last equation shows you how to combine the first two.
C = A + B
A = 2D + 3
B = 3D - 12
C = 2D + 3 + 3D - 12
C = 5D - 9
