Answer:
Step-by-step explanation:
Given that an investigator measuring various characteristics of a large group of athletes found that the correlation between the weight of an athlete and the amount of weight that athlete could lift was 0.60.
Correlation coefficient is the measure of association and a positive value implies that increase in one value causes increase in the other.
Hence out of the given options correct ones are
c) The more an athlete weights, on the average the more he weights.
d) The more an athlete can lift, on the average the more he weighs.
e) 60% of athlete's lifting ability can be attributed to his weight alone.

Answer:
The answer is 1/20
Step-by-step explanation:
8y(y - 4) + 3y(y + 2) =
8y^2 - 32y + 3y^2 + 6y =
11y^2 - 26y
Answer:
20 m
Step-by-step explanation:
Given:
- Length in mud = ¹/₂ its length
- Length in water = ¹/₃ its length
- Length above water = 3 ¹/₃ m
Let x be the length of the lamp post.
Convert 3 ¹/₃ to an improper fraction:
The total length of the lamp post (x) is the sum of the three given lengths:
Multiply both sides by 6:
Isolate x:
Therefore, the whole length of the post is 20 m.
