Answer:
1/4
Step-by-step explanation:
Since there is 4 colors and four rooms there is a 1/4 possibility that she paints the room green.
To find the average speed, we need to find his speed during 3/4 of the trip and then the 52.5 miles.
So you know that 52.5 is 1/4 of his total trip. That means if we multiply that by 3, that's how many miles he traveled in 2.5hrs. (157.5)
To calculate speed, divide distance by time.
For 3/4 of his trip (157.5), it took him 2.5 hours.
157.5/2.5 = 63mph
For the remaining 52.5 miles, it took him an hour.
52.5/1 = 52.5mph
Now average those two speeds to get the average speed for the whole trip.
(63+52.5)/2= 57.6mph
Answer:
possible
Step-by-step explanation:
the question asks what is the likelyhood of making a free throw 70% of the time, whcih is possible beacuase you can make it, you can also miss it. there are several professional basketball players that have that percentage. but it is not likely that someone could just shoot 70 percent. so i would stick with possible
Answer:
The sample was not chosen at random.
Step-by-step explanation:
For it to be a representative sample the selection needs to be completely random.
Answer:
87 deg
Step-by-step explanation:
Angles E and F are internal and adjacent to one another, hence they both add up to 180 deg
(2x+3) + (3x-33) = 180
2x+3 + 3x-33 = 180
5x -30 = 180
5x = 180 + 30 = 210
x = 42 deg
Angle E = 2(42) + 3 = 87 deg
