Answer:

Step-by-step explanation:

It is done by Middle term splitting.

Taking the general equation ax² + bx + c, by middle term splitting, "b" should be splitted such that the numbers either on adding or on subtracting must be equal to "b" and their products must be equal to "a x c".

For example, in the question it's already given that the equation 8x² + bx + c is middle term splitted into 8x² + px + qx + 3.

So, that means "p x q" must be equal to "8 x 3", i.e., 24.

Hope it helps :)

If you have one ace what is the probability that you have a second ace

Basile [38]

The way your question is worded, the probability is zero. One ace is not two aces.

There are 420 students. 63 students were out sick. What percent of the student population is ill?

emmainna [20.7K]

To find the percentage,here's what we can do:
$\frac{student \: out \: sick}{original \: population} \times 100\%$

The percentage would then be:
=63/420×100%
=3/20×100%
=0.15×100%
=15%

Therefore the answer is 15%.

Hope it helps!
