. Internet providers: In a survey of 600 homeowners with high-speed Internet, the average monthly cost of a high-speed Internet plan was $64.20 with a standard deviation of $11.77. Assume the plan costs to be approximately bell-shaped. Estimate the number of plans that cost between estimate the number of Internet plans whose between $52.43 and $64.20

hope this : )

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
