Answer:
Step-by-step explanation:
(a). The explanatory variables are the antioxidant group, the response variable is the result of the rate of colon cancer
(b)The design of the experiment is stratified Random sampling. I'll suggest there divided into equal group of 216 each.
(c). Double blind is when the people subjected to the experiment are not in the know if they're given placebo or the real antioxidant
(d) No significant difference mean, there is no convincing relationship that those that engage in using antioxidant have reduced colon cancer rate.
(e) Awareness of its history in family, age also.
Answer:
second one: -4x +6
third one: 4x - 16
fourth: 245x + 30
fifth: 81x - 21x
(last one) sixth: 1600x + 8x
( if this goes wrong then I did something else)
Answer:
option d -1 is the answer
Answer:
<u>-4</u>
Step-by-step explanation:
Average rate of change (Table 1) :
- A(x) = h(4) - h(1) / 4 - 1
- A(x) = 9 - 3 / 4 - 1
- A(x) = 6/3 = 2
Average rate of change (Table 2) :
- A(x) = j(4) - j(1) / 4 - 1
- A(x) = 0 - 6 / 4 - 1
- A(x) = -6/3 = -2
Difference : -2 - 2 = <u>-4</u>
