Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring.

Hook wants to set aside $2000 this year for a vacation. She plans on saving $48 dollars each week. There are 52 weeks in a year.

Doss [256]

I think it is reasonable. She will have extra cash (almost $500) but that isn't a bad thing when you are going on a vacation.

If you need to know how to do it, what I did was take the $48 and the 52 weeks and multiply them together to get $2,496.... But if you think in your own opinion it's not reasonable than say she could trim down her savings and only try to earn about 40 dollars each week; you get to the closer amount of $2,000 with $2,080...

I hope this helps. Choose for yourself though! <3 Good luck! (:

How many quarts are in 40 gallons

Dafna11 [192]

To find out how many quarts there are in 40 gallons, we simply need to know how many quarts there are in one gallon. As the name implies, there are 4 quarts in one gallon, so we simply need to multiply 4 * 40 to find the amount of quarts in 40 gallons.

4 * 40 = 160

There are 160 quarts in 40 gallons.
Hope that helped! =)

2. In a recent survey conducted by the International Nanny Association, 4,176 nannies were placed in a job in a given year. Only

Natali [406]

Answer:

There is a 0.57% probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

Desired outcomes:

The number of male nannies selected. 24 of the nannies placed were men. So the number of desired outcomes is 24.

Total outcomes:

The number of nannies selected. 4,176 nannies were placed in a job in a given year. So the number of total outcomes 4176.

Find the probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").

$P = \frac{24}{4176} = 0.0057$

There is a 0.57% probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").
