Answer:
The final mean is higher
Step-by-step explanation:
The mean of all the scores = ![\frac{90 + 85 + 98 + 60 + 84 + 78}{6\\} = \frac{495}{6} = 82.5\\](https://tex.z-dn.net/?f=%5Cfrac%7B90%20%20%2B%2085%20%2B%2098%20%2B%2060%20%2B%2084%20%2B%2078%7D%7B6%5C%5C%7D%20%3D%20%5Cfrac%7B495%7D%7B6%7D%20%3D%2082.5%5C%5C)
The mean of the scores with the 60 dropped = ![\frac{435}{5} = 87](https://tex.z-dn.net/?f=%5Cfrac%7B435%7D%7B5%7D%20%3D%2087)
The final mean is higher
That will always happen when you drop the lowest score. I worked it out for you so that you would see that it happened in your case.
The answer is 15, because
280 × .95 = 266
280 - 266 = 14
Assuming that these are seperate equations:
<h3>Problem 1: x^2-5x-6</h3><h3>Problem 2: x^2+3x-40</h3><h3>Problem 3: x^2-7x-30</h3>
Problem 1:
1) Use the sum-product pattern.
x² - 5x - 6
x² + x - 6x - 6
2) Common factor from the two pairs.
x² + x - 6x - 6
x (x + 1) - 6 (x + 1)
3) Rewrite in factored form.
x (x + 1) - 6 (x + 1)
(x - 6) (x + 1) ----> Answer
Problem 2:
1) Use the sum-product pattern.
x² + 3x - 40
x² + 8x - 5x - 40
2) Common factor from the two pairs.
x² + 8x - 5x - 40
x (x + 8) - 5 (x + 8)
3) Rewrite in factored form.
x (x + 8) - 5 (x + 8)
(x - 5) (x + 8) ----> Answer
Problem 3:
1) Use the sum-product pattern.
x² - 7x - 30
x² + 3x - 10x - 30
2) Common factor from the two pairs.
x² + 3x - 10x - 30
x (x + 3) - 10 (x + 3)
3) Rewrite in factored form.
x (x + 3) - 10 (x + 3)
(x - 10) (x + 3) ----> Answer

you do rise over run, which is y2-y1/x2-x1
1.0395 *10^9
Hope that Helps!
Would appreciate for brainiest answer.
