Answer:

-12.5

Step-by-step explanation:

To easily get the area of the parallelogram, we will label the vertices .

A= 1, -2.... X1, y1

B= 5,8... X2, y2

C= 3,3.... X3, y3

D= 0,8.... X4, y4

Before that, let me state that:

The Area of a parallelogram is defined as :

1/2 det (X1 (y2 - y3) + X2 ( y3 - y1) + X3 (y1 - y2)

In the order from the question:

A = (-2(8-3) + 5(3-3) + 3( 3-8)) / 2

A = -2(5) + 5(0) + 3(-5)

A = -10 + 0 - 15 / 2

A = -25/2

A = -12.5

Answer:

a= 1 , b = 1/16 , c = 1/256 , d= 3/2 , e=4/9 , f= 16/81

Step-by-step explanation:

The first table is given as;

x 4⁻ˣ

-1 4

0 1

2 1/16

4 1/256

a= 1 , b = 1/16 , c = 1/256

The second table is given as;

x {2/3}^x

-1 3/2

0 1

2 4/9

4 16/81

d= 3/2 , e=4/9 , f= 16/81

The frequency table shows a set of data collected by a doctor for adult patients who were diagnosed with a strain of influenza.

Alexxx [7]

Answer:

The answer would be the second plot

Step-by-step explanation:

The frequency table show how many sick patients there are in a single age range. In the first two plots, the total dots between numbers 24, 25, 26, 27, 28, and 29 add up to 3, and the other 2 plots do not, so those are not correct.

When we add up the total of dots from ages 30-34 on the first plot, there are only 4 sick patients. On the second graph, there are 6 total patients in that age range. Therefore, the dot plot that corresponds with the frequency table is the second one.

3/4+?/2=13/4 what is answer

Otrada [13]

The answer is x=5.

Solve for x. (The question mark should be x.)

$\frac{3}{4}+\frac{x}{2}=\frac{13}{4}\\\frac{3}{4}+\frac{x}{2}-\frac{3}{4}=\frac{13}{4}-\frac{3}{4}\\\frac{x}{2}=\frac{5}{2}\\\frac{2x}{2}=\frac{5\times 2}{2}\\x=5$
