Answer:

Median is 110

Step-by-step explanation:

Let us write the data shown on the line plot

They are in ascending order as follows:

70,80,90,90,100,100,100,110,110,110,110,120,1200,120,120,130,130,140

There are 18 entries

The middle entries are 9 and 10

Hence median = average of 9th and 10th

= 110

NEED HELP WITH 7 AND 8<br> I WILL GOVE BRAINEST ONLY IF YOU ACTUALLY DO THE PROBLEMS

mihalych1998 [28]

7:
Parallel lines have the same slope
y = -3x + b
Plug in the x and y values from the point
5 = -3(-4) + b
5 = 12 + b
-7 = b
Answer to 7: y = -3x -7

8:
Perpendicular lines have opposite reciprocal slopes
y = -2x + b
Plug in x and y from the point
-6 = -2(7) + b
-6 = -14 + b
8 = b
Answer to 8: y = -2x + 8

Find the exact value of cos theta, given that sin thetaequalsStartFraction 15 Over 17 EndFraction and theta is in quadrant II.

vova2212 [387]

Answer:

$cos \theta = -\frac{8}{17}$

Step-by-step explanation:

For this case we know that:

$sin \theta = \frac{15}{17}$

And we want to find the value for $cos \theta$ , so then we can use the following basic identity:

$cos^2 \theta + sin^2 \theta =1$

And if we solve for $cos \theta$ we got:

$cos^2 \theta = 1- sin^2 \theta$

$cos \theta =\pm \sqrt{1-sin^2 \theta}$

And if we replace the value given we got:

$cos \theta =\pm \sqrt{1- (\frac{15}{17})^2}=\sqrt{\frac{64}{289}}=\frac{\sqrt{64}}{\sqrt{289}}=\frac{8}{17}$

For our case we know that the angle is on the II quadrant, and on this quadrant we know that the sine is positive but the cosine is negative so then the correct answer for this case would be:

$cos \theta = -\frac{8}{17}$

Choose the correct ordered pairs represented in the table. The following table gives per unit cost for furniture and shows selli

erastova [34]

Given the table

C : 1, 2, 3, 4, 5

F(C) : 4, 6, 8, 10, 12

Usually, the independent variable is represented by the x-value while the dependent variable (or the function) is represented by the y-value.

Thus the points represented by the table are:

(1, 4), (2, 6), (3, 8), (4, 10) and (5, 15).
