Answer:
The roots of the equation are x=-3 and x=-2.5
Step-by-step explanation:
<u><em>The correct quadratic equation is</em></u>
2x^2+11x+15=0
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
therefore
The roots of the equation are x=-3 and x=-2.5
35% = .35.
First, you make 35% into a fraction 35/100. Then make it into simplified form.
35 divided by 5 and 100 divided by 5 35/5 = 7 and 100/5 =20.
So,
35%=.35=35/100=7/20
7/20
is your answer
X^2 + 6x - 27
(x - 3)(x + 9)
The answer is: (x - 3)(x + 9).
Answer:
The correct option is b.
Step-by-step explanation:
The formula for standard deviation is
where, 
is mean of the data and n is number of observation.
The variance of a stock's returns can be calculated by the above formula.
Variance of stock's returns is the average value of squared deviations from the mean.
Therefore the correct option is b.
Short answer: NO.
28 cups is exactly equal to 14 pints. (There are 2 cups per pint.)
