A set of data with 100 observations has a mean of 267. There are six outliers in the data set, which have a mean of 688. If the six outliers are removed, what

Mean of remaining

94 observation= 240.1277

Approximately = 240

Step-by-step explanation:

First the mean of the data with 100 observation is 267, so the summation of the set of data is equall to 267*100= 26700

Now we have six outliers with mean of 688, so total summation of the outliers = 688*6 = 4128

The mean of the remaining set of data with (100-6)= 94 observation is

(26700-4128)/94= 22572/94

Mean of 94 observation= 240.1277

Approximately = 240

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
