Answer:
You never gave the answer choices but it should look something like this.
5 ⋅ 8.5 = x
or
x / 5 = 8.5
as for x. X=42.5
Answer:
<u>the mean-average of the data without the outliers is 22572/94 = 240.12766 correct to four digits.</u>
Step-by-step explanation:
If the six outliers are removed, what is the mean average of the remaining data... is ASSUMED what the question was supposed to ask. I'll go out on a limb here, because there really isn't much else you can calculate with just
this much data anyways. I refer to the mean or average as the mean-average....just sayin'
Mean-Average = total/count , which means the total = count * mean-average.
Well, the data containing the outliers has a mean-average of 267 and a count of 100 statistics as given in the problem. So the total of all of the data including the outliers is 26700.
Likewise, the six outliers have a mean-average of 688 as given in the problem.
So the total of the outliers is 688 * 6 = 4128.
As a result, the total of the 94 statistics when the six outliers are rejected is 26700-4128=22572.
Katy spends 8/10. 1/10 and 1/5=2/10 and 1/2=5/10 so 1/10+2/10+5/10=8/10 or 4/5 simplified.

Answer:
two real roots
Step-by-step explanation:
y = -2x^2 + 9x - 7
This is in the form
ax^2 +bx+c
a = -2 b = 9 c = -7
The discriminant is
b^2 -4ac
(9)^2 - 4(-2) (-7)
81 - 56
25
Since the discriminant is greater than zero, there are two real roots
