Hey there! I'm happy to help!
We have 24 total beads, and we have 6 red ones. This gives us a probability of 6/24, which simplifies to 1/4. However, we do this twice with replacement (we put the bead back, so the probability stays the same), so we multiply that probability twice to find the probability of it happening twice.
1/4×1/4=1/16
Therefore, the probability that both beads are red is 1/16.
Have a wonderful day! :D
Answer:
They're called constants.
Step-by-step explanation:
Hope this helped!
The actual distance is 280 miles
The distance for round trip is 560 miles
It costs $ 72.8 for gas on a round trip
<em><u>Solution:</u></em>
Given that,
Sean is looking at an atlas and the key at the bottom shows for every 1 and 1/2 inch on the map is approximately 80 miles of actual distance
Therefore,
Sean measured it to be about 5 and 1/4 inches on the map
Let "x" be the actual distance
Thus, we can say,
This forms a proportion and we can solve the sum by cross multiplying
Thus the actual distance is 280 miles
<em><u>How far will Sean drive round trip (there and back, no sightseeing)? </u></em>
Round trip = 280 + 280 = 560 miles
If Sean’s car gets 20 miles per gallon and gas averages about $2.60 a gallon, approximately how much will Sean spend on gas for a round trip?
cost = 28 x 2.60 = 72.8
Thus it costs $ 72.8 for gas on a round trip
Answer:
x = 3
Step-by-step explanation:
since it's hitting 3 on the x axis and just goes up and down where 3 is, all the points have an x of 3 and nothing else. making the equation x = 3
