What is 10 over 64 in simplest form

kykrilka [37]

To write a fraction in simplest form, you have to divide the numerator and the denominator by their greatest common factor.

Factors of 10: 1, 2, 5, 10
Factors of 64: 1, 2, 4, 8, 16, 32, 64
Common Factors: 1, 2
Greatest Common Factor: 2

$\frac{10}{64} = \frac{10/2}{64/2} = \frac{5}{32}$

Identify the equation that describes the line in slope-intercept form. slope = 2 , point (- 1, 2) is on the line

JulijaS [17]

<u>Answer:</u>

$y=2x+4$

<u>Step-by-step explanation:</u>

Given a slope and a point on the line, you can use point slope form and then rearrage your terms into slope-intercept form

<u>SLOPE-INTERCEPT FORM</u>: $y=mx+b$ , where "m" is your slope and "b" is your y-intercept
<u>POINT-SLOPE FORM: </u> $(y-y_{1}) =m(x-x_{1})$ , where $y_{1}$ represents the y-coordinate of your point, $x_{1}$ represents the x-coordinate of your point, and $m$ represents the slope

$(y-2)= 2(x-(-1))$

Point-slope form

$(y-2)=2(x+1)$

$y-2=2x+2$

$y=2x+4$

Slope-intercept form

For the data set 6,5,10,11,13, the mean, x, is 9. What is the standard deviation?

Ratling [72]

Answer:

3.39

Step-by-step explanation:

We will use SD formula to find our answer.

$\sigma=\sqrt{ \frac{\sum (x-\overline{x})^{2}}{N-1} }$

$\sigma$ = Standard deviation.

$\overline{x}$ = Mean.

N= Numbers of data-points.

We have been given that mean of our data set is 9. So we will find the square of each data point's distance to the mean.

Now let us substitute our given values in above formula.

$\sigma=\sqrt{ \frac{(6-9)^{2}+(5-9)^{2}+(10-9)^{2}+(11-9)^{2}+(13-9)^{2}}{5-1} }$

$\sigma=\sqrt{ \frac{(-3)^{2}+(-4)^{2}+(1)^{2}+(2)^{2}+(4)^{2}}{4} }$

Upon adding the square of distances we will get,

$\sigma=\sqrt{ \frac{9+16+1+4+16}{4} }$

$\sigma=\sqrt{ \frac{46}{4} }$

Upon dividing 46 by 4 we will get,

$\sigma=\sqrt{ 11.5}$

Upon taking square root of 11.5 we will get,

$\sigma=3.3911649915626341\approx 3.39$

Therefore, the standard deviation for our given data set will be 3.39.
