Answer: 50%
Step-by-step explanation:
Total number of jerseys = 50
Total number of medium-sized = 25
% of medium - sized jersey = number of medium sized/ total number x 100
that is:
% of medium sized = 25/50 x 100
% of medium sized = 50
Answer:
2.86%
Step-by-step explanation:
assuming there is no replacement
There is a total of 6 envelopes
Since the question is asking for red, then green, then red, order is very important
The probability of a red is 3/7
Since we have selected 1 envelope, there are only 6 total envelopes left so the probability of a green is 1/6
Then we need a red again
Since we have selected 2 envelopes, one of which is red, there are only 5 total envelopes and 2 red envelopes so the probability of a red is 2/5
Now we multiply all of these so 3/7x1/6x2/5 = .02857142857
To find the percentage, you multiply by 100 so 2.857142857
Im pretty sure they want you to estimate it so 2.86% is what I would put but it depends on your teacher
Answer:
Step-by-step explanation:
The given function is,
The parent function of it is,
In graph y-axis is an asymptote (vertical) , so never crosses the y-axis. Hence no y intercept. And x intercept of is x=1.
The sign of x is changed in the given function as compared to its parent function
While reflecting over y axis or x=0 line, only the sign of x changes.
So graph of is the reflection of over y axis. Hence it has no y intercepts, x intercept at x= -1 and y-axis as asymptote (vertical).
To find how many minutes she took per brain teaser, divide the time by how many she did.
72/6=12
She spent 12 minutes on average for each brain teaser.
Hope this helps.
