Y=7 because there is no slope and the Y intercept is at 7.
Answer:
p² -16pq + 36q²
Step-by-step explanation:
Given
(-
p + 6q)²
= (-
p + 6q)(-
p + 6q)
Each term in the second factor is multiplied by each term in the first factor, that is
-
p(-
p + 6q) + 6q(-
p + 6q)
=
p² - 8pq - 8pq + 36q² ← collect like terms
=
p² - 16pq + 36q²

Answer:
52.74% probability that a randomly selected airfare between these two cities will be between $325 and $425
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:

What is the probability that a randomly selected airfare between these two cities will be between $325 and $425?
This is the pvalue of Z when X = 425 subtracted by the pvalue of Z when X = 325. So
X = 425



has a pvalue of 0.7088
X = 325



has a pvalue of 0.1814
0.7088 - 0.1814 = 0.5274
52.74% probability that a randomly selected airfare between these two cities will be between $325 and $425
