what is the median of the mountain data?
a.
14,500 ft
c.
14,530 ft
b.
14,515 ft
d.
14,573 ft

Option (b) is correct.

The median of the given data is 14,515 ft.

Step-by-step explanation:

  Given : Data for the the heights in feet of the 30 tallest mountains in the United States.

We have to find the median of the given data .

Median of the data  is the middle value.

Consider the given data,

To calculate the median : First put the data in ascending order and then find the middle value.

If the number of terms is odd then the middle value is median

And if the number of terms is even then the average of two middle value is median.

We arrange the given data in ascending order,

142691427014286142941430914345143611437014410144201442114433144701449414500145301457314730148311495015300156381588515979162371639016500174001800820320

Since, The number of terms are 30 (even)

Thus, The median is the average of two middle values

Here, Middle terms are 15th and 16th term,

15th term is 14500

and 16th term is 14530

Thus, Median is

Thus, The median of the given data is 14,515 ft.

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
