Answer:
A proportional relationship exists between two values x and y when they can be expressed in the general form. Hope this helps
Step-by-step explanation:
4-2=2 that is the answer to
Answer:
1. y = mx + b
Step-by-step explanation:
y = mx + b
2) to find the y intercept you need to see what cross | ( 8,5)
3) 5 = m(8) = b
4) your slope is negative form the why it pointing
5) in this case your slope is 1/3
6) so now you can do your first step now that you have your (y,x) and slope (your solving for (b)
7)
5 = 1/3 (8) + b
5 = 2.6 + b
5 = 2.6
-2.6
2.4 = b
Answer:
(b)
Step-by-step explanation:
When two p and q events are independent then, by definition:
P (p and q) = P (p) * P (q)
Then, if q and r are independent events then:
P(q and r) = P(q)*P(r) = 1/4*1/5
P(q and r) = 1/20
P(q and r) = 0.05
In the question that is shown in the attached image, we have two separate urns. The amount of white balls that we take in the first urn does not affect the amount of white balls we could get in the second urn. This means that both events are independent.
In the first ballot box there are 9 balls, 3 white and 6 yellow.
Then the probability of obtaining a white ball from the first ballot box is:
In the second ballot box there are 10 balls, 7 white and 3 yellow.
Then the probability of obtaining a white ball from the second ballot box is:
We want to know the probability of obtaining a white ball in both urns. This is: P( and )
As the events are independent:
P( and ) = P () * P ()
P( and ) =
P( and ) =
Finally the correct option is (b)
Answer:
Step-by-step explanation:
They are different numbers:
0.269 + 50.9 = 51.169
0.26 + 50.9 = 51.16
