Julie, a cafeteria manager, is making a large amount of chicken soup to serve for lunch tomorrow.
Nimfa-mama [501]

Answer:

12 cups

Step-by-step explanation:

Divide the given amount of celery, 18 cups, by the number of cups in the given ratio, 3 cups.

18/3=6

This number is how many times the ratio Julie used. Use this number to multiply the ratio number of carrots, 2 cups

2*6=12

Julie uses 12 cups of carrots in her chicken soup

\frac{12}{18}=\frac{2}{3}

Let f(x) = xe−x if x ≥ 0 and f(x) = 0 if x &lt; 0<br> Is f a probability density function?
Lynna [10]

Yes. f(x) is a PDF if

• f(x) \ge 0 for all x in the support; this is true, since e^{-x}>0 for all x, and multiplying a positive number x doesn't change this fact;

• the integral of f(x) over its support is 1; this is also true, since

\displaystyle \int_{-\infty}^\infty f(x) \, dx = \int_0^\infty xe^{-x} \, dx = 1

which can be computed by parts.

A principle of $2000 is placed ina saving account at 3% APR compounded annually. How much is in the account after one year, two
Kisachek [45]

Answer:

1 year:  $2060

2 years: $2121.80

3 years: $2185.45

Step-by-step explanation:

Compound interest formula is A = P(1 + \frac{r}{n}^{nt) where A is the final amount, P is the initial principal balance, r is the interest rate, n is the number of times interest applied per time period, and t is the number of time periods elapsed. In our case, P would be equal to 2000 dollars, r would be equal to 0.03, for 3 percent, and our n value would just be one, so the final equation is:

2000(1.03)^t

First, let's evaluate t for 1, as in one year.

2000 * 1.03^1 = 2000 x 1.03 = 2060

Two years: 2000 * 1.03 squared = 2121.80

Three years: 2000 * 1.03^3 = 2185.45!

Hope this helps!
