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.
Answer:
x= 35
Step-by-step explanation:
Cos x = Sin( 20+x)
Sin ( 90 – x) = Sin(20+x)
90 – x = 20+x
2x = 70
x = 35
Answer:
3
Step-by-step explanation:
24 + (-1) = 23, 12 + (-2) = 10, 8 + (-3) = and 6 + (- 4) = 2, none of the sums are equal to 3, therefore b = 3 would give a prime quadratic. The correct answer is then A. 3
Answer:
Step-by-step explanation:
a reciprocal is a number that when multiplied by a given number gives 1 as product.
16 * x = 1
x = 1/16
9/10 * x = 1
x = 10/9
Answer:
y = 1x + 1/2
Step-by-step explanation:
y2 - y1 / x2 - x1
2 - 3/2 / 3/2 - 1
= 1/2 / 1/2
= 1
y = 1x + b
3/2 = 1(1) + b
3/2 = 1 + b
1/2 = b
