Ms. Johnson asked her class to write an equivalent expression to

dimulka [17.4K]

No one got the correct answer. The answer is supposed to be 7(2d+3k-dk-1). All the coefficients are divisible by 7, thus only the integers are changed. However, the variables cannot be a factor because they do not have the same variables that all the coefficients must have.

What is the median of the ages shown in this stem-and-leaf plot? 59.5 58.5 59.0 58.0 Stem and leaf plot titled Ages of college p

AlexFokin [52]

Answer:

Median = 59.0

Step-by-step explanation:

According to the given data:

The data represents the signatures collected by different volunteers are as following in order from least to the greatest:

30, 32, 41, 44, 44, 45, 53, 55, 58, 59, 62, 62, 62, 65, 66, 68, 75, 75, 76

And it is required to find the median:

The median of a data set is the middle data point.

The number of data set is 19

So, the median will be at the place number 10

So, the median is 59
