Easy question! I just need reassurance (;´༎ຶٹ༎ຶ`) A school administrator wants to know the average age of the 25,000 kindergartners in her state at the beginning of the school year. She randomly selects 1,000 kindergarteners in the state, assuring that the group accurately represent all kindergartners in the state, and finds the average age to be 5 years 10 months.

What assumption can she make regarding the approximate average age of all kindergartners in the state?

A. No assumptions can be made regarding the average age of kindergartners in the state because the sample is biased.

B. The approximate average age of kindergartners in the state is less than 5 years 10 months.

C. The approximate average age of kindergartners in the state is greater than 5 years 10 months.

D. The approximate average age of the kindergartners in the state is 5 years 10 months.

step-by-step explanation:

answer: what are the following choices

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

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.
