Answer:
48%
Step-by-step explanation:
P (not getting a speckled rock) = 12/18 = 2/3
P (not getting a green rock) = 13/18
2/3 * 13/18 = 26/54 = 13/27 ≈ 48%
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.
The slope formula is y2-y1 divided by x2- x1 so -8-6=-14 and -1+3=2
-14/2 =-7
Answer:
5.6 quarts
Step-by-step explanation:
x + .15(8) = .50(8+x)
x + 1.2 = 4
.50x + 1.2 = 4
.50x = 2.8
x = 2.8/.50
x = 5.6 quarts
Answer:
c=2.4a+2537.8
a=-2.5/6c+1057.4
Step-by-step explanation:
solve for c:
2.50c+6a=6344.50
-6a -6a
2.50c=-6a+6344.50
/2.50 /2.50 /2.50
c=2.4a+2537.8
solve for a:
2.50c+6a=6344.50
-2.5c -2.5c
6a=-2.5c+6344.50
/6 /6 /6
a=-2.5/6c+1057.4
