There are 4 boys and 7 girls with a total of 11. Now, how many 4 persons group combinations are possible.
=> 1 boy and 3 girls
=> 2 boys and 2 girls
=> 3 boys and 1 girl
Thus, there are 3 possible combinations that might happen.
first off, we know this equation is a quadratic equation, so it is of the form y = ax² + bx + c, where "a, b and c" are digits or constants, and we have no clue what they are.
well, let's take a peek at the table of values and let's make, hmmm usually we'd end up with a system of equations of 3 variables, but in this case we can cook it earlier by being wimpy and using the (0 , 0) point from the table, that says that y = 0 and x = 0, then we'll be using the point (-2 , 0), again being wimpy for the 0 and we know that y = 0 whilst x = -2.
Your answer would be A: y = 1/4x +9
First convert the mixed fraction into an improper fraction. To do this, multiply the whole number by the denominator and then add the numerator. Then place it over the denominator.
4 1/2 => 9/2
Now we can multiply.
9/2 * 3/4 = 27/8
Now convert it into a mixed number.
To do this, first find how many times 8 can go into 27. Which is 3 times.
That will be our whole number. 3 * 8 = 24
Then subtract 24 from 27. 27 - 24 = 3. That will be our numerator.
And the 8 will in 27/8 will be our denominator.
And the result is 3 3/8
