Write 120 as a product of prime numbers

GenaCL600 [577]

Here is the process:

120/ 2 = 60

60 / 2 = 30

30 / 2 = 15

15 / 3 = 5

Notice that 2, 3 and 5 are all prime numbers

So, 120 = 5*3*2*2*2

PLZ HELP MEEEE 40 POINTS!

ASHA 777 [7]

Step-by-step explanation:

We have been given that Jeanie stated that the equation of this line best fit for the scatter plot is $y=\frac{1}{2}x+8$ .

Let us find the slope of the line of best fit using points (2,7) and (4,6) in slope formula.

$\text{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\text{Slope of line of best fit}=\frac{6-7}{4-2}$

$\text{Slope of line of best fit}=\frac{-1}{2}$

We can see that slope of line of best fit is $-\frac{1}{2}$ .

Since the equation of a line written in slope-intercept is in form: $y=mx+b$ , where m=slope of line, b= y-intercept.

Upon substituting m= $-\frac{1}{2}$ and coordinates of one point in slope-intercept form of equation we will get,

$6=-\frac{1}{2}\times 4+b$

$6=-2+b$

$6+2=-2+2+b$

$8=b$

Upon substituting m= $-\frac{1}{2}$ and b=8 in slope intercept form, we will get,

$y=-\frac{1}{2}x+8$

We can see that equation of the line of best fit is $y=-\frac{1}{2}x+8$ . Jeanie got 1/2 as slope of the line of best fit, which is wrong, therefore, Jeanie's equation of the line of best fit is not correct.
