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:
(-1,5)
(3, 1/125)
Step-by-step explanation:
g(x) = (1/5) ^x
Lets check the points
(1,0)
0 = (1/5) ^1
0 = 1/5 False this is not on the graph
(-1,5)
5 = (1/5) ^ -1
Remember negative exponents flip the fraction inside the parentheses
5 = 5/1 True this is on the graph
(3, 1/125)
1/125 = (1/5)^ 3
1/125 = 1^3/ 5^3
1/125 = 1/125 true this is on the graph
(-2,1/25)
1/25 = (1/5) ^-2
Remember negative exponents flip the fraction inside the parentheses
1/25 = 5^2/1^2
1/25 = 25 false this is not on the graph
The least common denominator is 2
First, let's simplify each expression by combining like terms:
A: 9x-3x-4 = 6x-4
B: 12x-4 = 12x-4 (Already Combined terms)
C: 5x+x-4 = 6x-4
When looking at the list of equations, it is clear that only Expression A and C are equivalent. Brianna failed to combine like terms and plug in more points than 0.
I Hope this Helps!
