<h3>
<u>Explanation</u></h3>
- Given two coordinate points.
- Calculate and find the slope by using rise over run formula with two given points.
Substitute the coordinate points in.
Hence, the value of m is - 1/3.

<u>Answer</u></h3>
<u>
</u>
Answer:
3. w=P/2-L
Step-by-step explanation:
<u>Given formula:</u>
<u>Solving for w:</u>
- P=2(l + w)
- P/2 = 2(l + w)/2
- P/2 = l + w
- P/2 - l = l + w - l
- P/2 - l = w
- w = P/2 - l
<u>Correct answer choice is:</u>
Answer:
N - 2 r t²
x = - ------------
7x
Step-by-step explanation:
N = 2 r t² - 7 r x
solve for x
N = 2 r t² - 7 r x
N + (-2 r t²) = (2 r t² - 7 r x) + (-2 r t²)
N - 2 r t² = 2 r t² - 7 r x - 2 r t²
N - 2 r t² - 2 r t² + 2 r t² = - 7 r x
N - 2 r t² = 7 r x
therefore,
N - 2 r t²
x = - ------------
7x
Standard Form looks like this:
Also, A cannot be negative and there are no fractions in Standard Form.
Now that we know the rules of Standard Form, let's get x and y on one side.
-2/3y = 2 + 8/15x
Subtract 8/15x from both sides.
-8/15x - 2/3y = 2
Multiply 2/3 by 5/5 to get a common denominator.
-8/15x - 10/15y = 2
Multiply everything by 15 to rid of the fractions.
-8x - 10y = 30
Multiply everything by -1 to make A positive.
8x + 10y = -30
8x + 10y = -30
The mean is affected by outliers.
- TRUE - the mean is the average, so each value affects it.
The mean is always a more accurate measure of center <span>than the median.
- FALSE: Although the mean gives a better idea of the values, the center for Normal distributions is described using the median value.
</span>Removing an outlier from a data set will cause the standard deviation to increase.
- FALSE: Removing an outlier from a data set makes the data more Normal, reducing the standard deviation, not increasing it.
If a data set’s distribution is skewed, then 95% of its values will fall between two standard deviations of the mean.
- FALSE: the 68-95-99.9 rule works for a bell-curve distribution, a.k.a. a Normal distribution, not a skewed distribution.
If a data set’s distribution to skewed to the right, its mean will be larger than its median.
- TRUE: the mean is always pulled in the direction of the skewness.
