Answer is D. Midrange of the data is 55

The actual midrange is 85 you just take you highest and lowest number which is 25 and 145 you add them which give you 170 and you divide that by 2 and gives you 85 and 85 is you’re midrange

A LOT OF POINTS!!!!!!! PLEASE HELP ME BECAUSE I DONT GET!!! Explain why 9(t - 1) is equivalent to 9t - 9 PLEASE TELL ME THE CORR

Misha Larkins [42]

Easy there on the caps, partner.

The nine, using the distributive property, distributes itself across the brackets, and so 9 times t is 9t and 9 times -1 is -9.

Therefore, 9(t-1) = 9t -9

N Example 3, the points are(0,3500) and (5,1750). Write an equation that represents the distance y (in feet) remaining after x m

Cerrena [4.2K]

Answer:

<h2>The time needed is 10 months.</h2>

Step-by-step explanation:

The given points are (0, 3500) and (5, 1750).

First, we use the formula below to find the slope of the line

$m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }=\frac{1750-3500}{5-0}=\frac{-1750}{5}=-350$

Which means the function is deacrasing with a ratio of 350 feet per month.

Now, we use the slope and one point to find the equation

$y-y_{1} =m(x-x_{1} )\\y-1750=-350(x-5)\\y=-350x+1750+1750\\y=-350x+3500$

This linear function shows that the situation started at the y-intecept (0, 3500), which means the month 0 had already 3500 feet. In other words, the total distance is 3500 feet. Now, the x-intercept will tell us the time needed to travel that distance.

$0=-350x+3500\\-3500=-350x\\x=\frac{-3500}{-350}\\ x=10$

Therefore, the time needed is 10 months.
