The cost of a daily newspaper varies from city to city. however, the variation among prices remains steady with a standard deviation of $0.20. a study was done to test the claim that the mean cost of a daily newspaper is $1.00. twelve costs yield a mean cost of $0.93 with a standard deviation of $0.18. do the data support the claim at the 1% level? note: if you are using a student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (in general, you must first prove that assumption, however.)

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
