People applying for a driver's license In California usually need to take a multiple choice test as a part of the application process. An administrator of these tests is curious about how much time people spend on the test. They take an SRS (simple random sample) of 151515 test results and find that the times are strongly skewed to the left with a mean of \bar x=14.2 x ˉ =14.2x, with, \bar, on top, equals, 14, point, 2 minutes. There are also a few outliers in the sample data. The administrator is considering using their data to make a confidence interval for the mean time. Which conditions for constructing a ttt interval have been met?

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.

i think it’s c i believe

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!

the answer is -1 1/5, also a
