Answer:

The Mean would decrease

Step-by-step explanation:

Pay attention to the phrase is always true

We know an outlier will always affect the mean, not always the Median, so it eliminates Median answers.

If the mean is 80, we can infer the cluster would be below 91 be cause the mean is lower than the outlier.

So if we take out an outlier that is significantly greater, That means the mean would decrease becuase the significantly greater outlier raises the mean.

Therefore the answer is The Mean would decrease

d1i1m1o1n [39]

Answer:

Step-by-step explanation:

Request of activities so increase then division, at that point deduction and expansion.  

9*8 = 72  

72/2 = 36  

72-3 = 69  

69+36 = 105

Another way of saying it is:

Utilize the request for tasks to improve on mathematical articulations. The request is brackets, types and roots, augmentation and division, expansion and deduction. Duplication and division are "something similar" so you would utilize the first that happens from left to right.  

Bit by bit clarification:  

7^2 - 3 + 9 x 8 ÷ 2  

49 - 3 + 9 x 8 ÷ 2  

49 - 3 + 72 ÷ 2  

49 - 3 + 36  

49 - 39  

W=10

Answer:

X=SMALL BOX.

Y=LARGE BOX

THEREFORE,X+Y=21

X=21-Y

THEREFORE,25(21-Y)+70Y=1110 POUNDS

525-25Y+70Y=1110

525+45Y=1110

45Y=1110-525

45Y=585

Y=585/45

Y=13 .

Therefore,13 large box and8 small box..

The height of a side on a pyramid is 11 inches long, and its square base has sides that are 6 inches long. What is the surface a
Vitek1552 [10]
The answer is 168 because 11 x 6 is 66 but on a triangle it would be half of that cause the formula of a triangle a = bh/2 so thats 33 and since theres 4 sides you would do 33 x 4 = 132 then 6 x 6 cause the base of the triangle = 36 and 132 plus 36 is 168
