NOW PLEASE HELP ME !! ☹️ |Two data sets collected during an investigation are shown.
Data Set A
75.8, 79.2, 78.6, 82.1, 76.7, 77.3
Data Set B
89.1, 85.4, 87.2, 88.9, 86.7, 90.9
Which of the following is true?
A Data set A has the greatest variability
around the mean due to the higher mean
absolute deviation.
B Data set B has the greatest variability
around the mean due to the higher mean
absolute deviation.
C Data sets A and B have the same variability
around the mean due to the same mean
absolute deviation.
D There is not enough information to
determine the variability difference between
data sets A and B.

answer: i guess 105 degrees?

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

7 9/10 as an improper fractions is 79/10.

hope it : )
