attashe74 [19]

Answer:

The answer to your question would be D.

D. Range: 20

Mean: 10

Median: 9

Mode: none

Step-by-step explanation:

1, 2, 3, 8, 9, 12, 14, 20, 21

Range: 21 - 1 = 20

Mean: 1 + 2 + 3 + 8 + 9 + 12 + 14 + 20 + 21 = 90/9 = 10

Median: 9

Mode: there are no mode in the following given data set.

Write an equation for the line graphed below: y=??

Zepler [3.9K]

Answer: y=-2x-1

Step-by-step explanation:

First let's find the slope by using the formula $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$\frac{-3--1}{1-0} \\\frac{-2}{1} \\-2$

The equation for slope intercept form is y=mx+b where m is the slope and b is the y-intercept

The y-intercept is -1 giving us the equation

y=-2x-1

Solve trigonometric function 2csc∅- 2cos^2 ∅ ×csc∅

Eduardwww [97]

Answer:

$2\sin(\theta)$

Step-by-step explanation:

$\csc(\theta)=\dfrac{1}{\sin(\theta)}$

$\sin^2(\theta)+\cos^2(\theta)=1\implies \sin^2(\theta)=1-\cos^2(\theta)$

$2\csc(\theta)- 2cos^2(\theta)\times csc(\theta)$

$=\dfrac{2}{\sin(\theta)}-\dfrac{ 2cos^2(\theta)}{\sin(\theta)}$

$=\dfrac{ 2[1-cos^2(\theta)]}{\sin(\theta)}$

$=\dfrac{ 2sin^2(\theta)}{\sin(\theta)}$

$=2\sin(\theta)$
