People who eat lots of fruits and vegetables have lower rates of colon cancer than those who eat little of these foods. Fruits and vegetables are rich in "antioxidants" such as vitamins A, C, and E. Will taking antioxidants help prevent colon cancer? A medical experiment studied this question with 864 people who were at risk of colon cancer. The subjects were divided into four groups: daily beta-carotene, daily vitamins C and E, all three vitamins every day, or daily placebo. After four years, the researchers were surprised to find no significant difference in colon cancer among the groups(a) What are the explanatory and response variables in this experiment?(b) Outline the design of the experiment. Use your judgment in choosing the group sizes.(c) The study was double-blind. What does this mean?(d) What does "no significant difference" mean in describing the outcome of the study?(e) Suggest some lurking variables that could explain why people who eat lots of fruits and vegetables have lower rates of colon cancer. The experiment suggests that these variables, rather than the antioxidants, may be responsible for the observed benefits of fruits and vegetables.

Answer:

105km

Step-by-step explanation:

It is given that; (2.5cm : 15km) is the proportion by which distances are scaled down on a map. One can use this to make a proportion and solve to find how many (km) would represent (17.5cm). (x) will represent the unknown or the number of (km) that one has to solve for.

2.5 : 15 = 17.5 : x

Cross products,

262.5 = 2.5x

Inverse operations,

262.5 = 2.5x\n/2.5\n\n105 = x

Use a commutative property to complete the statement 2x + 16

The answer should be B.

This is because if you multiply, you’ll get the answer of 3/8 which is less than 1/2 (4/8) but not close to zero, thus leaving B as the best option.

Answer:

a =7.5

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+ b^2 = c^2  where a and b are the legs and c is the hypotenuse

a^2 + 10 ^2 = 12.5^2

a^2 + 100  =156.25

Subtract 100 from each side

a^2 = 56.25

Take the square root of each side

sqrt(a^2) = sqrt( 56.25)

a =7.5
