Step-by-step explanation:
Replacement means the probability of each trial is the same (the trials are independent).
For example, let's say you have a standard deck of 52 cards, and you want to find the probability of drawing a queen card twice.
There are 4 queens, so the probability on the first draw is 4/52.
You then replace the queen, so there are still 4 queens in the deck. So the probability on the second draw is still 4/52.
The total probability is the product: 4/52 × 4/52 = 1/169
If you didn't replace the queen after the first draw, there would have been 3 queens in the deck, and the probability on the second draw would have been 3/52.
Answer:
97.5 miles
Step-by-step explanation:
d = 65t
where d is the distance in miles and t is the time in hours
Therefore, to calculate how many miles the car travels in 1.5 hours, substitute t = 1.5 into the equation:
d = 65 x 1.5 = 97.5 miles
No, because it <em>is not a straight line when graphed.</em>
Answer:
m=9/8 or 1 1/8
Step-by-step explanation:
m= change in y over change in x
2 - -7 = 9
5 - -3 = 8
