Answer:
At most 9.12 joules should be required for the bottom 80% of bottled water
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
How much energy should be required for the bottom 80% of bottled water?
At most the 80th percentile.
The 80th percentile is X when Z has a pvalue of 0.8. So it is X when Z = 0.84.
At most 9.12 joules should be required for the bottom 80% of bottled water
Answer:
a) 16
b) -8
c) 2
Step-by-step explanation:
Given:
p = 2
q = -3
r = -1
a)
5p - 2q
Substitute variables.
5(2) - 2(-3)
Multiply.
10 + 6
Add.
16
b)
pq + pr
Substitute variables.
(2)(-3) + (2)(-1)
Multiply.
-6 - 2
Subtract.
-8
c)
pr²
Substitute variables.
(2)(-1)²
Square -1.
(2)(1)
Multiply.
2
