Answer:
Independent means that one has no effect on the other. Exclusive means one cannot happen alongside the other. In simpler terms, independent events can be thought of as the chance it'll rain and how many people are flossing their teeth in the morning. Both happen, but neither one impacts the other.
Exclusive, on the other hand, means only one can happen. Lets say at nine in the evening your favorite show is on. However, you have an early morning and should be asleep by nine. You cannot both be asleep and watching your favorite show, and so these events are exclusive.

11/66= 6
4/x= 6
4•6= 24

hope this is clear :))
All you have to do is substitute the y value from the 1st equation into the second equation and solve...
a) y= 2-x
5x + 4y = 5
Substitute (2-x) into the second equation anywhere there is a y...
5x + 4y = 5
5x + 4(2-x) = 5
Now solve
5x + 8 - 4x = 5
5x - 4x + 8 = 5
x + 8 = 5
x = -3
Now that you have a solution for x, substitute -3 into either of the original equations anywhere there is an x then solve for y...
y = 2 - x
y = 2 - (-3)
y = 2+3 = 5
You solved for x and got -3 and solved for y and got 5, so your solution set is
(-3, 5).
Now check it by substituting both numbers into one of the original equations and you should have a true statement if it is correct...
y = 2 - x
5 = 2 - (-3)
5 = 2+3
5 = 5
True statement... it checks!
note* during the check, if the equation would have worked out to something like 2 = 5, then that is a false statement therefore the solution set would be wrong and you'd have to go back and find the mistake.
Answer:
Q = 3
Step-by-step explanation:
3 * P + 7 * Q + 15 * R = 102
7Q = 102 - 3P - 15R
Q = (102 - 3P - 15R)/7
Try P = 2; R = 3
Q = 51/7 not an integer
Try P = 2; R = 5
Q = 21/7 = 3
Solution: P = 2; Q = 3; R = 5
Answer: Q = 3
Answer:
25
Step-by-step explanation:
divide 150 by 30 to find how many times 30 goes into 150. Your answer should be 5. Then times 5 by 5 to get 25. a resting human can take in 25 liters of air in 150 seconds.
hope this helps :3
if it did pls mark brainliest
