Answer:y= -2x/3 + 2
Step-by-step explanation:
Answer:
2.56 gallons per minute!
Step-by-step explanation:
44.8 gallons - 32 gallons = 12.8 gallons
12.8 gallons in 5 minutes - so we need to find the unit rate (per one minute)
12.8/5 = 2.56
2.56 gallons per minute!
Answer:
-2*3
Step-by-step explanation:
If she had to refund $2 for each cup (-2) and she refunded 3 cups (3) she would lose a balance of -2*3.
Answer:
length = 163592
Width = 327184
520 = question B
it would become the same as the width = question c
Answer:
18.14% probability that you would get at least 12 questions correct.
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 problem, we have that:

What is the probability that you would get at least 12 questions correct?
This is 1 subtracted by the pvalue of Z when X = 12. So



has a pvalue of 0.8186.
So there is a 1-0.8186 = 0.1814 = 18.14% probability that you would get at least 12 questions correct.
