on the first of each month, sasha runs a 5k race. she keeps track of her times to track her progress. her time in minutes is recorded in the table:

jan 39.55 july 34.38
feb 40.51 aug 36.48
mar 41.01 sept 39.87
apr 37.76 oct 50.32
may 35.32 nov 40.59
june 33.28 dec 41.71

determine the difference between the mean of the data, including the outlier and excluding the outlier. round to the hundredths place.

a.38.98
b. 38.22
c. 1.21
d.1.01

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

answer: 800
