Can someone please help me on this??

Usimov [2.4K]

Answer:

Step-by-step explanation:

To solve this use the equation $x^2 -15x - 50 = y$ given in the problem and the value y = 50. Substitute y = 50 then solve for x by factoring.

$x^2 -15x - 50 = 50\\x^2 - 15x -100 = 0$

Find two numbers which multiply to -100 and also add to -15. The numbers are -20 and 5.

So the factored form is (x-20)(x+5) = 0.

Set each factor equal to 0 and solve.

(x-20) = 0 so x = 20.

(x+5)=0 so x = -5.

This means the temperature is 20 degrees C or -5 degrees C. Only 20 is an option. The solutions is C.

What is 25% of 25,000

prisoha [69]

You do cross multiplying so 25/100 because a 100 is the most of a percent you can get so it that percent over a 100=x/25,000. there's a x because you don't know what the number on top of the 25,000 is.Now do cross multiplying, 25 times 25,000 divided by 100 is 6250

Llana [10]

Answer:

The total number of marbles in the bag is 50.

Step-by-step explanation:

Here, we have n trials, without replacement. So the hypergeometric distribution is used.

The mean of the hypergeometric distribution is:

$E(X) = \frac{n*k}{N}$

In which n is the number of items in the sample, k is the number of items in the population that are classified a success and N is the size of the population.

15 marbles are drawn:

This means that $n = 15$
