Answer:

Mean = 58.25

Median = 57.5

Mode = 49

Step-by-step explanation:

We are given the following data set:

55, 51, 74, 61, 67, 60, 49, 49

Formula:

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{466}{8} = 58.25$

Sorted data:

49, 49, 51, 55, 60, 61, 67, 74

Mode is the entry with highest frequency.

49 appeared two times.

Mode = 49

Formula:

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

$\text{Median} = \dfrac{55+60}{2} = 57.5$

All these are less than 60 seconds, which indicates that students perceive 1 minute to pass sooner than it actually has.

Jenny and Mark are reading the same book for their English class.

Harrizon [31]

Answer:

10 days

Step-by-step explanation:

Jenny has read 50 pages and will read 15 each day.

The equation would be: 15x+50

Mark will read 20 pages daily.

The equation would be: 20x

In both equations x represents days.

You set both equal to each other because you want to know when they read the same amount of pages.

15x+50=20x

...you subtract 15x from both sides

50=5x

...and divide by five to get: 10 days
