NeTakaya

Answer:

Step-by-step explanation:

Hello!

You have a sample of 200 people, they were asked their primary source of news, categorized in (1) Television, (2) Radio, (3) Internet and (4) Other.

And your objective is to test if the proportions in this sample follow the known frequencies 10%, 30%, 50%, and 10%.

The propper statistic test to use to probe if the sample follows the known or historical distribution is Chi-Square goodness of fit test. In this test, what you state in the null hypothesis is the model or distribution you want to test. In this case, you've to write down the proportions for each category:

H₀: P(1)= 0.10; P(2)= 0.30; P(3)= 0.50; P(4)= 0.10

I hope you have a SUPER day!

Complete the equation of the line through (2,-2)(2,−2)left parenthesis, 2, comma, minus, 2, right parenthesis and (4,1)(4,1)left
Daniel [21]

Answer:

y=\frac{3}{2}x-5

Step-by-step explanation:

There are a couple of ways to solve this, depending on what you already know.

Point-Slope Form

y-y_1=m(x-x_1)  where <em>m</em> is the slope and (x_1, y_1) is a point on the line.

First, calculate the slope using the two given points (x_1, y_1), (x_2, y_2).

m=\frac{y_2-y_1}{x_2-x_1}=\frac{1-(-2)}{4-2}=\frac{3}{2} .

Fill in the point-slope pattern

y-(-2)=\frac{3}{2}(x-2) \\ y+2=\frac{3}{2}x-3 \\ y=\frac{3}{2}x-5

There's the equation in slope-intercept form (y=mx+b).

Slope-Intercept Form

Use y=mx+b directly.

Find the slope just like the above, so m=\frac{3}{2}.

Now, plug one of the points (either one!) together with <em>m</em> into

y=mx+b\\-2=\frac{3}{2}(2)+b \\ -2=3+b \\ b=-5

Now you know the value of <em>b</em>, so the equation for the line is

y=\frac{3}{2}x-5

Steve stayed after school for extra activities 55% of the 180 school days this year. How many days did Steve stay after school?
musickatia [10]

Answer:

11/20 or 99/180 days

Step-by-step explanation:

55/100 converted to ?/180

180/100=1.8

so you would do the same on the numerator which is 55*1.8=99

99/180= 33/60=11/20
