Step-by-step explanation:
Simplify 8 - {x - (5 + x)}
We need to simplify 8-(x- (5+x))
To simplify it we need to use order of operation
Order of operation is PEMDAS
Parenthesis , exponents , multiply , divide , add and subtract
So first we start with parenthesis
multiply negative sign inside the parenthesis
combine like terms x-x becomes 0

Step-by-step explanation:
-Given the dimensions of the box is 8.7 in, 14 in and 10 in.
Let length=14 in, width=10 in and height =8.7 in
#The surface area of a rectangular prism is calculated as:
Hence, the wrapping paper needed has an area of
Given:
The data set is
10, 10, 11, 12, 13, 13, 13, 14, 14, 15, 15, 15, 16, 17, 17, 17, 35
To find:
Effect on mean, median, range after removing the outlier, 35.
Solution:
We have, the data set
10, 10, 11, 12, 13, 13, 13, 14, 14, 15, 15, 15, 16, 17, 17, 17, 35
Mean of the data set is 15.12.
because n=17, which is odd.
Median is 14.
Range is 25.
After removing the outlier, 35, the data set is
10, 10, 11, 12, 13, 13, 13, 14, 14, 15, 15, 15, 16, 17, 17, 17
Mean of the new data set is 13.875, which is less than 15.12.
because n=16, which is even.
New median is 14, which is same as original median.
So, the new range is 7 which is less than 25.
Therefore, the mean of the data set will decrease, the median of the data set will not change, the Range of the data set will decrease.
