Step-by-step explanation:

Given:

Number of rooms in care center = 3

Number of children attend the center = c

Find:

Number of children in each room

Computation:

Number of children in each room = Number of children attend the center / Number of rooms in care center

Number of children in each room = c / 3

I need to 2,4,6,8 <br> But please send me the work too

Ugo [173]

ok for number 2.) 2+8+1+5+1+3+1+7+5+4+3+1=41 and 41 divided by the number of number which is 12= 3.41666666667

the mean for number 2 is 3.41666666667.

for the median you put the number from least to greatest, like so:

1, 1, 1, 1, 2, 3, 3, 4, 5, 5, 7, 8.

The middle is 3 and 3 so 3+3 divided by 2 is 6 so the median is 6.

I cant do mode but range is 8-1 divided by 2

If you're trying to solve for x, you need to use the quadratic formula.
$\frac{-b+/- \sqrt{b^2 - 4(a)(c)} }{2a}$
Plug in the numbers from the standard form of a quadratic equation
(which is $ax^2 + bx + c = 0$ )
$\frac{34+/- \sqrt{34^2 - 4(16)(15)} }{2(16)}$
From here, this solves down to
$\frac{34+/- \sqrt{196}}{32}$
Take the square root of 196, which is 14
$\frac{34+/- 14}{32}$
Now, you can solve for both the + and - variations on the equation.
The solutions to your equation are 1.5 and 5/8 (probably)
