9=30*25+25*53. which = 2975.
You have to split the shape into two smaller ones to make two rectangles and find the area of both and add them together.
With 12, you need to find the area of both shaped and subtract the triangle form the rectangle to get 93.5.

PLEASE HELP WILL MARK BRAINLIEST<br><br>Find the area of the right triangle.
sweet-ann [11.9K]

Answer:

Step-by-step explanation:

This right triangle is on a grid.

The area is the height * base/2

The base is on a line segment parallel to the x axis which is 6 squares.

The height is on a line segment parallel to the y axis which is 2 squares

The area is the height * base /2

Area = 6 * 2 /2 = 12/2 = 6 square units.

Jason and Yolanda both drew a simple random sample from a non-normally distributed population of 25,000. Jason’s sample consiste
UkoKoshka [18]

Answer:  Last Option is correct.

Step-by-step explanation:

Since we have given that

Total number of population = 25000

Percent of sample of Jason = 0.24%

Percent of sample of Yolanda's = 0.32%

So, Number of population according to Jason's sample is given by

\frac{0.24}{100}\times 25000\\\\=0.0024\times 25000\\\\=60

Number of population according to Yolanda's sample is given by

\frac{0.32}{100}\times 25000\\\\=0.0032\times 25000\\\\=80

Both the sample can be used to make inferences about the population

Hence, Last Option is correct.

Determine whether the improper integral converges or diverges, and find the value if it converges.
salantis [7]

Answer:

Integral will be diverging in nature

Step-by-step explanation:

We have given integral \int_{5}^{\infty}\frac{3}{2}x^2dx

Now after solving the integral

[\frac{3}{2}\frac{x^3}{3}] limit from 5 to infinite

So [\frac{3}{2}\frac{\infty^3}{3}]-[\frac{3}{2}\times \frac{5^3}{3}]=\infty

As after solving integral we got infinite value so integral will be diverging in nature

Which table of ordered pairs, when plotted, will form a straight line? Select two answers.
aniked [119]

Answer:

Options A and D are answers.

Step-by-step explanation:

The ordered pairs are given in the table in options. We have to choose which table gives a straight line.

We know that if the increase or decrease of y value with respect to corresponding x values is uniform then the plot of those x and y corresponding values will form a straight line.

Now, in table A, the slope of each pair of x and y values is constant i.e.  

\frac{- 1 - 0}{- 2 - ( - 1)} = \frac{0 - 1}{- 1 - 0} = \frac{1 - 6}{0 - 5} = 1

Hence, it will give a straight line.

In table B, the slope of each pair of x and y values is not constant i.e.

\frac{7 - (- 3)}{- 2 - 0} \neq  \frac{- 3 - 12}{0 - 3}.

Hence, the plotted graph will not give a straight line.

In table C, the slope of each pair of x and y values is not constant i.e.

\frac{- 3 - 5}{- 4 - 0} = \frac{5 - 9}{0 - 2} \neq  \frac{9 - 12}{2 - 5}

Hence, it will not give a straight line.

In table D,  the slope of each pair of x and y values is constant i.e.

\frac{-8 - (- 4)}{- 2 - 0} = \frac{- 4 - 4}{0 - 4} = \frac{4 - 8}{4 - 6}

Hence, it will give a straight line.

So, options A and D answer.
