Answer:

The relationship is positive.

The model predicts a score of 60.

Not sure what part b is.

Step-by-step explanation:

Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.

By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.

Three cartons of juice cost $4.77? find the cost of 8 cartons

AleksAgata [21]

Note: Make the rule of three simple

cartoons __ price $
3 --------------- 4.77
8 --------------- y

Solving: (directly proportional)

$\frac{3}{8} = \frac{4.77}{y}$
Product of extremes equals product of means
 $3*y = 8*4.77$
$3y = 38.16$
$y = \frac{38.16}{3}$
$\boxed{\boxed{y = 12.72}}\end{array}}\qquad\quad\checkmark$

Answer:
The price of eight cartoons was $\$\:12.72$

ZanzabumX [31]

Answer:

This study casts doubts as the hypothesis does not support the women who are smokers, drinkers or use dyes besides the difference of breasts implants.

Step-by-step explanation:

This study casts doubts as the hypothesis does not support the women who are smokers, drinkers or use dyes.

If the null and alternate hypothesis are formulated as

H0 : silicone breasts implants cause illness in smokers, drinkers and hair dyed people

against the claim

Ha: silicone breasts implants do not cause illness in smokers, drinkers and hair dyed people

then there would be no doubt .

But as the null and alternate hypothesis are

H0: silicone breast implants cause illness in women

against the claim

Ha: silicone breast implants do not cause illness in women

This suggests that both categories of women have same characteristics.

But actually both categories do not have same characteristics. The breast implant women also , smoke, drin and dye hair.

So when the characteristics are changed the illness maybe caused by some other characteristics.
