Answer: c


Step-by-step explanation:

because to find the average is to add all your numbers up and to divide them by how many numbers you have

and the median is the finding the middle which is the average you line them up from lowest to greatest value and cross one off from the beginning and one from the end until you are left either one or two values

Evaluate the following double integral: xy dA D where the region D is the triangular region whose vertices are (0, 0), (0, 3), (
natulia [17]

Answer:

I= 84

Step-by-step explanation:

for

I=\int\limits^{}_{} \int\limits^{}_D {x*y}  \, dA =  \int\limits^{}_{} \int\limits^{}_D {x*y}  \, dx*dy

since D is the rectangle such that 0<x<3 , 0<y<3

I=\int\limits^{}_{} \int\limits^{}_D {x*y}  \, dA =  \int\limits^{3}_{0} \int\limits^{3}_{0} {x*y}  \, dx*dy =  \int\limits^{3}_{0} {x}  \, dx\int\limits^{3}_{0} {y}  \, dy  = x^{2} /2*y^{2} /2 =  (3^{2} /2 - 0^{2} /2)* (3^{2} /2 - 0^{2} /2) = 3^{4} /4 = 81/4

Christian reads 14 book every 23 week.
mihalych1998 [28]

Picture 1: The amount of tax for Veena's meal is $1.02

Picture 2: Christian reads \frac{3}{8} books per week.

Picture 3: 80% is equal to \frac{4}{5}.

Step-by-step explanation:

Picture 1: Veena ate lunch at a deli. She ordered turkey sandwich for $9.25 and a salad for $4.35. The tax was 7.5%. What is the amount of tax for Veena's meal.

Given,

Price of turkey sandwich = $9.25

Price of salad = $4.35

Total amount = 9.25+4.35 = $13.60

Tax = 7.5%

Amount of tax = 7.5% of total cost

Amount of tax = \frac{7.5}{100}*13.60

Amount of tax = \frac{102}{100} = \$1.02

The amount of tax for Veena's meal is $1.02

Picture 2: Christian reads 1/4 book every 2/3 week.  How many books does Christian read per week?

Given,

Books read every 2/3 weeks = 1/4 books

\frac{2}{3}\ weeks=\frac{1}{4}\ books\\

For determining the number of books read per week, we will multiply both sides by \frac{3}{2}

\frac{3}{2}*\frac{2}{3}\ week=\frac{1}{4}*\frac{3}{2}\ books\\\\1\ week = \frac{3}{8}\ books\\\\

Christian reads \frac{3}{8} books per week.

Picture 3: What percent is equivalent to \frac{4}{5}?

We will multiply the given fraction with hundred for calculating the percentage.

\frac{4}{5}*100\\\\\frac{400}{5}\\\\80\%

Therefore,

80% is equal to \frac{4}{5}.
