A fair spinner, shown below, is spun 176 times. How many times should a spin of "3" occur?
A.
exactly 88 times
B.
about 88 times
C.
about 44 times
D.
exactly 44 times
C. about 44 times
My apologies for the oversight. Let's correct that.
If a fair spinner is spun 176 times and the spinner has 8 equally likely numbers (1-8), then the probability of spinning a "3" on any single spin is 1/8.
To calculate the expected number of times a spin of "3" should occur in 176 spins:
(1/8) * 176 = 22
Therefore, a spin of "3" should occur approximately 22 times in 176 spins.
The correct answer is:
C. about 22 times
Thank you for your patience.
A. Pet Shop #2 generally has more birds per cage than Pet Shop #1.
This is based on the average number of birds per cage, considering the values in the tables. The average number of birds in Pet Shop #1 is (10+20+18+25+8) / 5 = 16.2 birds per cage, and the average number of birds in Pet Shop #2 is (18+25+20+32+26) / 5 = 24.2 birds per cage. Since the average number of birds per cage in Pet Shop #2 is higher, it can be concluded that Pet Shop #2 generally has more birds per cage than Pet Shop #1.
A. exactly 88 times
Since the spinner is fair, each number has an equal probability of appearing. Therefore, if the spinner is spun 176 times, "3" should occur approximately half of the time, which is 88 times.
you sure
Apologies for the confusion in my previous response. Let's correct that.
If the spinner is fair and has 8 equally likely numbers (1-8), then the probability of spinning a "3" is 1/8.
To calculate the expected number of times a spin of "3" should occur in 176 spins, you would multiply the probability of spinning a "3" by the total number of spins:
(1/8) * 176 = 22
Therefore, a spin of "3" should occur approximately 22 times in 176 spins.
So, the correct answer is:
B. about 22 times
pick an answer that I put
you sure its C
The tables below show the numbers of birds in five randomly selected cages from two different pet shops.
Pet Shop #1
Cage Number of Birds
1 10
2 20
3 18
4 25
5 8
Pet Shop #2
Cage Number of Birds
1 18
2 25
3 20
4 32
5 26
What is true about the data in the tables?
A.
Pet Shop #2 generally has more birds per cage than Pet Shop #1.
B.
Pet Shop #1 generally has more birds per cage than Pet Shop #2.
C.
There is no comparison between the two pet shops.
D.
Pet Shop #2 generally has less birds per cage than Pet Shop #1.
