Answer:y = -5x + 11
Step-by-step explanation:
First, find the slope (m) of the line that passes through these points:
m = (1-6) / (2-1) = -5/1 = -5
Then use the point slope formula to find the equation of the line:
m = (y-y0)/(x-x0)
-5 = (y-1)/(x-2)
-5(x-2) = y-1
y - 1 = -5x+10
y = -5x + 11
Answer:
The population mean is of 6.1667.
Step-by-step explanation:
Total sample size:
26 + 54 + 86 + 26 = 192
Mean:
To the mean is the sum of the midpoint of the class frequencies multiplied by its frequency(mean of 2 to 4 is 3, 4 to 6 is 5 and so on...). So
The population mean is of 6.1667.
Answer:
If you have two P(A) or two P(B) then the probability would not be 50% <em>{0.5}</em> it would be 100% <em>{0.10}</em> because it would be the same.
Step-by-step explanation:
The probability that Events A and B both occur is the probability of the intersection of A and B. The probability of the intersection of Events A and B is denoted by P(A ∩ B). If Events A and B are mutually exclusive, P(A ∩ B).

If you buy a matching red shirt and and a matching set of red pants it wouldn't be 50% of the outfit unless you wore the shirt with blue pants or wore the pants with a blue shirt.
Probability that Eli will get a blue pen: 6 / 13 ( there are 6 blue pens and 13 pens together ).
Probability that Eli will not get the pink highlighter: 6 / 9 ( yellow + green = 4 + 2 = 6 and there are 9 together ).
P = 6/13 · 6/9 = 6/13 · 2/3 = 2/13 · 2 = 4/13 = 0.3077 = 30.77%.
Answer:
The probability is 4/13 or 30.77%.
Answer:
(81/7)/27
Step-by-step explanation:
6/14 = x/27
6/14 x 27 = x
x = 11.57 = 81/7
