Sam’s Music Store wanted to take a survey of the age range of people that visited the store. Over the course of a week, they asked 40 people their age as they walked in. Below is a box plot of the collected data. Answer the following questions about the box plot in relation to the problem. 1.When Sam’s assistant was collecting the data she mistakenly noted that the oldest person was 48. The oldest person was actually 50. How will this affect the box plot?

Answers

A box plot contains 5 number summary. The information gathered from the box plot are:
1) minimum number
2) 1st quartile
3) median
4) 3rd quartile
5) maximum

Since the box plot of the collected data is not shown, I can only say that the maximum number will be affected by the error.

maximum number of 48 should have been maximum number 50.

Hey! Im counting on you guys!Ken drove 174 miles in 3 hours. The equation y = 57x represents the distance in miles, y, Brenda drove in x hours. Determine who had the faster driving speed and by how much.

Please form your answers like so:
Of the two drivers, (...) had the faster driving speed by (...) mile(s) per hour.

Answers

Answer:

Ken is faster by 1 mile per hour

Step-by-step explanation:

Ken's speed

174/3 = 58 mph

Brenda's speed

57 mph as per formula

Comparing the values, we see that

Ken is faster by 58 - 57 = 1 mile per hour

Answer:

To find Ken's speed divide total distance by total time:

174 miles / 3 hours = 58 miles per hour.

In the equation for Brenda, the 57 is the miles per hour because you would multiply that by x ( hours) to get total miles (y).

Ken had the faster driving speed.
