That graph would be non-linear
Step-by-step explanation:
33+22+90=145
180-145=35
x=180-35
<u>x=</u><u>1</u><u>4</u><u>5</u>
Answer:
y=3x goes with m=3, b=0
y=7 goes with m=0, b=7
y=-3x+4 goes with m=-3, b=4
y=1.5x-7 goes with m=1.5, b=-7
y=-1.5x-4 goes with m=-1.5, b=-4
Step-by-step explanation:
The b represents the y- intercept in a graph (where the line crosses the y axis). The m represents the slope of the line. You can find the slope by taking the rise of the graph and dividing it by the run (rise/run). If you get the numbers in the equation form y=mx+b, then you just take the information they give you out of the equation.
Answer:
We will not reject the null hypothesis.
There is not enough evidence to support the claim that the mean age of death
-row inmates is different from 36.2 years.
Step-by-step explanation:
Consider the provided information.
The average age of an inmate in death row in 1989 was 36.2 years of age.
The sociologist collects a sample of 32 death-row inmates and finds that their mean age is 38.9 with a standard deviation of 9.6 years. Test the Sociologist’s claim at 0.05 significance level.
From the above information.
, ![H_a: \mu \neq 36.2](https://tex.z-dn.net/?f=H_a%3A%20%5Cmu%20%5Cneq%2036.2)
,
,
, n=32
This is a two sided test, with df = 32-1 = 31 and the critical values are
.
Now find the z score as shown:
![z=\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}}}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B%5Cbar%20x-%5Cmu%7D%7B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D)
Substitute the respective values:
![z=\frac{38.9-36.2}{\frac{9.6}{\sqrt{32}}}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B38.9-36.2%7D%7B%5Cfrac%7B9.6%7D%7B%5Csqrt%7B32%7D%7D%7D)
![z=\frac{2.7}{\frac{9.6}{5.6568}}}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B2.7%7D%7B%5Cfrac%7B9.6%7D%7B5.6568%7D%7D%7D)
![z=1.59](https://tex.z-dn.net/?f=z%3D1.59)
Since, 1.591 doesn’t lie in the critical region, hence we will not reject the null hypothesis.
There is not enough evidence to support the claim that the mean age of death
-row inmates is different from 36.2 years.
The two numbers are <u>12 and 51.</u>
<h3>
EXPLANATION</h3>
To solve this, I did 63-15, to get 48.
I then divided this by 4, to get the first number, which is <u>12.</u>
To find the second answer, I multiplied 12 by 3, which is 36, and then added the 15 back on, to get <u>51.</u>
<u>51 + 12 = </u><em><u>63</u></em>
