You want to find ; that is, given that you randomly choose from the pool of women, the probability that she does not exercise.
By definition of conditional probability,
496 of the total 1026 people are woman, and 341 of the 1026 people are women and do not exercise, so
A simpler way of doing this is to look at what's called the marginal distribution of women in the table. Basically this comes down to ignoring all but the data pertaining to the women. There's a total of 496 women, and 341 of them do not exercise. So the probability that a given woman does not exercise is 341/496.
Answer: the answer would be F
Step-by-step explanation:
Answer:
R(-2,0)
S(0,-4)
T(-4,-3)
Step-by-step explanation:
So first you gotta subtract 2 from each x value and 1 from each y value. After you do that, you get:
R(0,2)
S(-4,0)
T(-3,4)
then i put it all onto a graph, and rotated it 90* counterclockwise, from the origin, which puts it in quadrant 3, with the final coordinates above.
First of all, you organize all of the info that you're given. We know that the points are (x, y). Therefore, 8 is x and 5 is y. 5/7 is your m, since m represents the slope.
x = 8
y = 5
m = 5/7
b = y-intercept, which is the missing info
Then, you put it into a multi-step equation.
The slope equation formula is y = mx + b. Now, we solve for the equation.
y = mx + b
5 = 5/7(8) + b (missing info is the y-intercept, so that's why it stays as "b")
5 = 5/7(8/1) + b (any whole number converted into fractions always have a denominator of 1)
5 = 40/7 + b At this point, since 5 as a fraction is 5/1, you need to
-40/7 -40/7 + b multiply the numerator and denominator by 7 so that
_____________ you're able to subtract 40/7 from it. So, 5 x 7 = 35 and
1 x 7 = 7, giving you the fraction of 35/7. 35/7 - 40/7 =
-5/7.
-5/7 = b
Finally, you've got all the info you need to write the equation. As a result, you just substitute the letters with the numbers:
m = 5/7
b = -5/7
y = 5/7x - 5/7
I hope I helped and that you understood my explanations! :)
