Answer:
The percentage of regional phone companies whose operating expenses were closer to the mean than the operating expenses of Company A were to the mean is 73%.
Step-by-step explanation:
The Company A's operating expenses were $27.00. This is $2.93 less than the regional mean.
The companies whose operating expenses are closer to the mean are the ones that have expenses $2.93 below or above the mean.
The fraction of companies that are closer to the mean is equal to the proability of having expenses between those two limits:
Answer:
This is a proportional relationship, the constant of proportionality is 20m/s and it represents that the horse can run 20 meters every second.
Equation: d = 20s, where d=distance and s=number of seconds.
Step-by-step explanation:
In order to find out whether this relationship is proportional, you need to see if the rate at which the horse runs is constant (the same). If you look at the three sets of data (24, 480), (40, 800) and (60, 1200) where the pair is (seconds, meters), you can see that for any two sets of data the change in meters divided by the change in seconds is consistently 20m/s. For example:
Since the constant is 20, we know that the horse can run 20 meters every second. To find the horse's total distance, we need to multiply the rate by the number of seconds that it runs:
d = 20s
C because if you look at the intercept it’s a y and the y inception is equivalent to 4 so y=4x-14
The answer is C.
2 is the rise
3 is the run
Answer: $1125
Step-by-step explanation: 7500 x 3%= 225 Then multiply 225 by the 5 years. You will then get 1125. Marsha earned $1,125 in interest.
I hoped this helped, have a great rest of your day!
