Rita drank the following ounces of milk during the last week

Andre45 [30]

Answer:

Mean = 14.14

Mode = 14

Median = 14

Range = 16

Step-by-step explanation:

Given Data Set : 18 , 14 , 10 , 22, 14 , 15 and 6

Identifying the mean

Mean = Sum of given data values / total # of given values

Here sum of given data values = 18 + 14 + 10 + 22 + 14 + 15 + 6 = 99

And there are 7 given data values

So mean = 99 / 7 =

14.14

( approximately )

Identifying the mode

The mode is the number that appears most often

14 appears twice, which is the most times out of any other value

Hence, the mode is

Identifying the median

The median is the middle number in terms of value

To make this easier, its best to order the given values from least to greatest
Doing so we acquire 6 , 10 , 14 , 14 , 15 , 18 , 22

Then you go to the middle of the listed terms.

Doing so we would end up with 14 being in the middle

Hence the median is

Identifying the range

Range = largest given value - smallest given value

Here the most rita drank was 22 ounces and the least amount of milk she drank was 6 ounces

So the range would be 22 - 6 =

ounces

And we are done!

−11b+7=40<br> Like what am I supposed to do??

Nataly [62]

Answer:

The answer is 3

Step-by-step explanation:

First write the equation as you see it.

-11b+7=40

Then switch the take away seven from the left side then place it in the right side but as a minus.

-11b=40-7

Next do the math on the right side.

-11b=33

Once you have done that you divide the number on right with the number on the left which leaves you with the answer.

b=-3

Hope this helped :)

Complete the equation of the line through<br> (-6, -5) and (-4,-4).<br> Use exact numbers.

Nutka1998 [239]

Answer:

y = $\frac{1}{2}$ x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 6, - 5) and (x₂, y₂ ) = (- 4, - 4)

m = $\frac{-4+5}{-4+6}$ = $\frac{1}{2}$ , thus

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 6, - 5), then

- 5 = - 3 + c ⇒ c = - 5 + 3 = - 2

y = $\frac{1}{2}$ x - 2 ← equation of line

A bicycle that usually sells for $230 is on sale for 25% off. What is the sale price?

zloy xaker [14]

The answer is $57.50.

Explanation:
To find the discounted price of an item, you multiply the original sell price of the item by a decimal version of the percentage. So in this case you would multiply .25 by 230 to get 57.5 or $57.50.

I hope I helped and good luck!
