Below is how tall (in meters) each of the five players on Deandra's basketball team is. 7.1 2 1.5 1.8 1.6 Find the median height

Svetradugi [14.3K]

Answer:

4.45 m

Step-by-step explanation:

From the question above,

Median is the middle of a given data of distribution.

Given:

Data : 7.1, 21.5, 1.8, 1.6.

Rearrenging the date in decending order

21.5, 7.1, 1.8, 1.6.

From the above,

median = (n+1)th/2

median = (7.1+1.8)/2

median = 8.9/2

median = 4.45 m.

Hence the median height = 4.45 m

Tacoma's population in 2000 was about 200 thousand, and has been growing by about 8% each year. If this continues, what will Tac

Anestetic [448]

Answer:

Tacoma's population in 2014 will be 587,439 people

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by the formula

$y=a(1+r)^x$

where

y is Tacoma's population in thousand

x is the number of years since 2000

r is the rate of change

a is the initial value

we have

$a=200\\r=8\%=8/100=0.08$

substitute

$y=200(1+0.08)^x$

$y=200(1.08)^x$

what will Tacoma's population be in 2014?

Find the value of x

$x=2014-2000=14\ years$

substitute the value of x

$y=200(1.08)^{14}=587.439\ thousand$

therefore

Tacoma's population in 2014 will be 587,439 people
