Plug 8 for y

8 = 2x + 4

Subtract 4

4 = 2x

Divide by 2

x = 2

Plug 16 for y

16 = 2x + 4

Subtract by 4

12 = 2x

Divide by 2

x = 6

Substitute 20 for y

20 = 2x + 4

16 = 2x

x = 8

Substitute 22 for y

22 = 2x + 4

18 = 2x

9 = x

So the values are 2, 6, 8, 9

The scatter plot shows the relationship between the test scores of a group of students and the number of hours they play compute
Sedaia [141]
Part A. The group of points labeled A is the dataset which reveals a decreasing linear relationship. Point B could be considered an outlier because it falls outside the normal pattern of data points. A possible reason for the outlier is that there are other factors effecting students test scores that are not being taken into I account like their environment/homelife, parental involvement in education and students responsibilities , time-management. This may reveal an underlying flaw in the hypothesis as any hours spent in extracurricular activities or other time consuming tasks/chores are not considered either.

part B. In the dataset (group A) there is a decreasing linear relationship meaning that as the number of hours spent playing pc games increases, test scores decrease.

What is <br> 12 m/mi = cm/s
yarga [219]

<em>1 Cancel m.</em>

12i=c*m/s

<em>2 Use rule a*b/c = ab/c</em>

12i=cm/s

<em>3 Multiply both sides by s.</em>

12is=cm

<em>4 Divide both sides by 12.</em>

is=cm/12

<em>5 Divide both sides by i</em>

s=cm/12/i

<em>6 Simplify cm/12/i</em>

s=sm/12i

Can someone help me?
mestny [16]

Answer:

Step-by-step explanation:

To do this, we must use the unit circle. At the angle \frac{\pi }{6} the coordinate pair is (\frac{\sqrt{3} }{2}, \frac{1}{2}) and the hypotenuse is 1

Now that we know these we can start using the trig functions

sin = y

cos = x

tan = \frac{y}{x}

And the other functions would be the reciprocal of these

csc = \frac{1}{y}

sec = \frac{1}{x}

cot = \frac{x}{y}

This would mean that

sinx = \frac{1}{2}

cosx =\frac{\sqrt{3} }{2}

tanx =\frac{1}{\sqrt{3} } or \frac{\sqrt{3} }{3} if you're supposed to rationalize your denominators

cscx = 2

secx = \frac{2}{\sqrt{3} } or \frac{2\sqrt{3} }{3}

cot = \sqrt{3}
