Answer:
The equation for the following graph:
Step-by-step explanation:
- You first need to find the slope by using the <u>slope formula</u>:
(where is the first point and is the second point)
-Use the given points and from the graph for the formula:
Then, you solve:
After you have found the slope, use the slope and the first point for the <u>point-slope formula:</u>
<u>(</u>where is the slope and is the first point)
Then, you solve:
So, the equation for the following graph is .
Hello!
A cube has 6 faces which is the shape of a square, all corners are 90 degrees and it’s x^3
Simple...
you have: x-3y=18
You want to convert it into slope-intercept form or y=mx+b form-->>>
x-3y=18
Isolate the variable-->>
x-3y=18
-x -x
-3y=-x+18
Now simply divide...
y=
Thus, your answer.
Answer:
yes he is
Step-by-step explanation:
he is correct because say if I multiplied 25 by 10 I would get 250 same would go for if I multiplied 10 by 25 I still would get 250.
I hope this helps
Answer:
Step-by-step explanation:
1) Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Let X the random variable that represent the scores, and for this case we know the distribution for X is given by:
And let represent the sample mean, the distribution for the sample mean is given by:
On this case
2) Calculate the probability
We want this probability:
The best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
