Look at the picture. Solve for y

Mumz [18]

Answer:

y = 5

Step-by-step explanation:

<u>Equation:</u>

m<DGF = m<DGE + m<EGF

<u>Given:</u>

m<DGF = 12y - 5

m<DGE = 5y + 6

m<EGF = 24

<u />

<u>Work:</u>

m<DGF = m<DGE + m<EGF

12y - 5 = 5y + 6 + 24

12y - 5 = 5y + 30

12y - 5y = 30 + 5

7y = 35

y = 5

Divide the combinations.<br><br> 60C3 / 15C3

Mariulka [41]

I hope you know what '!' means
2!=2
3!=6
4!=24
basicalkly times every natural number including and before that number

nCr= $\frac{n!}{r!(n-r)!}$
so
$\frac{60C3}{15C3}$ =
$\frac{ \frac{60!}{3!(60-3)!} }{ \frac{15!}{3!(15-3)!} }$ =
$( \frac{60!}{3!(60-3)!})(\frac{3!(15-3)!}{15!})$ =
$( \frac{60!}{3!(57)!})(\frac{3!(12)!}{15!})$ =
$\frac{(60!)(3!)(12!)}{(3!)(57!)(15!)}$ =
$\frac{(60!)(12!)}{(57!)(15!)}$ =
$\frac{(60!)}{(57!)(15)(14)(13)}$ =
$\frac{(60)(59)(58)}{(15)(14)(13)}$ =
$\frac{(30)(59)(58)}{(15)(7)(13)}$ =
$\frac{(6)(59)(58)}{(3)(7)(13)}$ =
$\frac{6844}{91}$

How to find the mean for negative numbers

statuscvo [17]

You can find the mean of negative numbers just the same as for positive numbers. It doesn't hurt for the mean to be negative.

For example, with the number -9, -5, -4, -3, -1 you can find the mean jsut as any other numbers

-9+-5+-4+-3+-1=-22

-22/5=-4.4

the mean for those set of numbers is -4.4
