Answer:
Mr Blake's science class
Step-by-step explanation:
The standard deviation is a measure of variation.
It tells us how far each of the data set in the distribution are far from the mean of the distribution.
The average score of students in Mr. Blake's science class was 73 with a standard deviation of 11, while the average score of students in Mrs. Arnold's class was 75 with a standard deviation of 10.
Since 11>10, Mr Blake's science class is more variable than Mrs. Arnold's class.
Answer:
Step-by-step explanation:
<u>Given function:</u>
- c(x) = 400 + 25x
- where x is the number of complete video games.
The complete video games can be expressed as positive integers or whole numbers, so the domain is whole numbers.
Correct choice is (4)
I believe the answer is 2
Answer: 7/75
Step-by-step explanation: An event may either be dependent or independent, depending on the effect the outcome of such event has on other events. A dependent events is one in which it's out ime is affected by the outcome of another event. On the other hand an independent event is not affected by the outcome of another event.
The event described above is a dependent event, because the outcome of my first try or pick will affect the possible outcome of my friend's first try.
Candy dish :
5 butterscotch ; 8 peppermint ; 12 chocolate
I and my friend both want peppermint:
P = required outcome ÷ Total possible outcome
Total possible outcome = 5+8+12 = 25
P(I pick peppermint on my first try) = 8/25
P(my friend picks peppermint on her first try) = 7/24
If I pick first, the outcome of my friend's event has been affected from the original
P = (8/25) × (7/24)
P = 56/600
P = 7/75
