In what different ways can 45 be written as the product of two positive integers?

1 answer:

4 0

First you need to know its common factors.

They are: 1, 3, 5, 9, 15, 45

And 45 = 1*45 = 3*15 = 5*9

So there should be 3 ways in total

What’s the answer to this question ?

HACTEHA [7]

Answer:

Step-by-step explanation:

Line pases through (6, 0) and (0, -6)

Slope = (0 - (-6))/(6 - 0) = 6/6 = 1

so y = 1*(x - 6) = x - 6

or x - y = 6

or 4x - 4y = 24

That is C

What is the equation of the line best fit for the following data? Round the slope and y-intercept of the line to three decimal p

kari74 [83]

Answer:

$y=1.383x-1.526$

Step-by-step explanation:

The given data table is

x : 4 7 10 12 13

y : 5 7 12 14 18

We need to find the equation of the best fit line.

The general form of a best fit line is

$y=mx+b$ .... (1)

where, m is slope and b is y-intercept.

$m=\frac{\sum_{i=1}^nx_iy_i-n\overline{x}\overline{y}}{\sum_{i=1}^nx_i^2-n\overline{x}^2}$

$b=\overline{y}-b\overline{x}$

Using the graphing calculator we get

$m=1.38321\approx 1.383$

$b=-1.52555\approx -1.526$

Substitute m=1.383 and b=-1.526 in equation (1).

$y=1.383x-1.526$

Therefore, the equation of best fit line is $y=1.383x-1.526$ .
