Answer:

3n+1

Step-by-step explanation:

Subtract one from all the values, you get multiples of 3 in the equation 3n=nth term

So when you add one back, your equation is 3n+1=nth term

Answer:

y = 45 / 2x + 50

Step-by-step explanation:

The best equation for the line of the best fit would be y = 45 / 2x + 50.

The slope would be 45 / 2 and the y-intercept would be ( 0 , 50 ).

I used the points, ( 0 , 50 ) and ( 4 , 140 ) to get the equation, slope, and the y-intercept.

I used those points because they were the most accurate ones that I know for now.

Also, remember the formula is, "y = mx + b."

Y=(3/5)x -3 and 5y =3x-10 these lines are and the second question?

azamat

Look at the first line: y = (3/5)x - 3. What happens if you multiply each term by 5, to eliminate the fraction?

5y = 3x - 3

Compare this to the second equation,

5y - 3x = -10, or 5y = 3x - 10.

The coefficients of x and y (as 3 and 5 here) determine the slope of a straight line. Since 5y = 3x is present in both equations, the two lines MUST be parallel.

y = 4
4y = 6 => y = 6/4

y+4 and y =3/2 are both horizontal lines. Since they are horiz., they are parallel.

If y varies inversely as x and y=23 when x=8 find y when x=4

valina [46]

<h2>INVERSE VARIATION</h2>

EQUATION: 

$y = \frac{k}{x}$

––––––––

First, find the constant of variation k using the formula k=xy.

$23 = \frac{k}{8}$

$k = (8)(23)$

$k = 184$

––––––––

Then, find y if x is equal to four using the formula y=184/x.

$y = \frac{184}{x}$

$y = \frac{184}{4}$

$y = 46$

Normal probability Density Function Use a graphing utility to graph the model probability density function with µ = 0 and ð = 2,

Nuetrik [128]

Answer:

Step-by-step explanation:

Hello!

The standard deviation (δ) is a measure of variability, this means, it shows how dispersed the data set is with respect to the mean. The population mean (μ) is a measurement of position. The three graphics have the same position μ=0 but their standard deviations change, this means, the form of their bells is different. The greater the value of the standard deviation, the more dispersed the data is you can see this graphically because the width of the bell will be greater.

Graph attached.

I hope it helps!

Answer:

Step-by-step explanation:

There will be a fence around the garden. ... per linear foot. About how much will the fencing costs altogether? Round to the nearest hundreth. Use 3.14 for π ... The straight part of the fence will equal the diameter (d) = 32. The rounded portion will be 1/2 the circumference = (pi)d/2 = (3.14)(16)=50.24.
