Answer:

False

Step-by-step explanation:

When a constant is added to every data value in a data set?

If you add a constant to every value, the mean and median increase by the same constant. For example, suppose you have a set of scores with a mean equal to 5 and a median equal to 6. If you add 10 to every score, the new mean will be 5 + 10 = 15; and the new median will be 6 + 10 = 16.

What is the equation of the line that is parallel to the given

slamgirl [31]

Answer:

$y=\frac{1}{5}x+\frac{12}{5}$

Step-by-step explanation:

Complete Question: What is the equation of line that is parallel to the line $y=\frac{1}{5}+4$ and passes through $(-2,2).$

$Let\ the\ equation\ of\ line\ is\ y=mx+c\\\\Since\ it\ is\ parallel\ to\ the\ line\ y=\frac{1}{5}x+4,\ the\ slope\ of\ both\ the\ lines\ will\ be\ same.\\\\Slope\ of\ y=\frac{1}{5}x+4\ is=\frac{1}{5}\\\\m=\frac{1}{5}\\\\Equation: y=\frac{1}{5}x+c\\\\It\ passes\ through\ (-2,2),\ This\ point\ will\ satisfy\ the\ equation.\\\\2=\frac{1}{5}\times (-2)+c\\\\c=2+\frac{2}{5}\\\\c=\frac{12}{5}\\\\The\ Equation\ is: y=\frac{1}{5}x+\frac{12}{5}$

Which of the following is an equation in slope-intercept form of the line that passes through the given point and with the given

Diano4ka-milaya [45]

Answer:

$y=2x-14$

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

In this problem we have

$m=2\\point\ (9,4)$

substitute the given in the equation

$4=2(9)+b$

Solve for b

$4=18+b$

subtract 18 both sides

$4-18=b$

$b=-14$

therefore

The linear equation in slope intercept form is equal to

$y=2x-14$

Mr. Ramirez gave his class

Angelina_Jolie [31]

Answer:

38 pages per hour

Step-by-step explanation:

Rate of reading = $\frac{\text{Total number of pages read by Davida}}{\text{Time taken to read}}$

By substituting the given values in the question,

Total number of pages read by Davida = $28\frac{1}{2}$ = $\frac{57}{2}$

Time taken by Davida = 45 minutes

Since, 1 minute = $\frac{1}{60}$ hours

Therefore, 45 minutes = $\frac{45}{60}=\frac{3}{4}$ hours

Rate of reading = $\frac{\frac{57}{2}}{\frac{3}{4} }$

= $\frac{57}{2}\times \frac{4}{3}$

= 38 pages per hour

Therefore, rate of reading by Davida is 38 pages per hour.

Sever21 [200]

Answer:

82 degrees

Step-by-step explanation:

Measure of arc ABC = 86*2 = 172 degrees.

Measure of arc DC = 360 - (145+172) = 360-317 = 43 degrees.

Measure of arc BCD = 121+43 = 164 degrees.

Measure of angle A = 164/2 = 82 degrees

What is the expression for "the difference between 5 times a number and twice that number"?

ycow [4]

Hey there :)

Before translating the sentence into mathematics, let r represent 'a number'

5 times a number = 5r
2 times that number = 2r

The difference between them = 5r - 2r

* Your equation
5r - 2r

* Solving the equation
= 5r - 2r
= 3r
