A June 2015 survey investigated the ownership of tablet computers by US adults. A random sample of 959 people were surveyed; 197 of the 455 men in the sample owned a tablet and 235 of the 504 women in the sample owned a tablet. Tiffany wants to test whether the survey results provide evidence of a difference in the proportion of US men and US women who owned a tablet in 2015

the amount you'd have after the work is $1.55

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

answer: it's d
