Answer:
there is 92.25
Step-by-step explanation:
15x2=30
then you have to find out 5% out of 45 because you need to get 35 not 30.
65*5 is what you get when you multiply them to get 325
Answer:
J
Step-by-step explanation:
You can see that one of the rings was originally $24 and on sale it is $18 which is 3/4 or 0.75 of 24. Then if you check that relationship with the other ones where you take the orginal price and find 3/4 or 0.75 of it you get all of the sale prices.
Answer:
This is 0.14 to the nearest hundredth
Step-by-step explanation:
Firstly we list the parameters;
Drive to school = 40
Take the bus = 50
Walk = 10
Sophomore = 30
Junior = 35
Senior = 35
Total number of students in sample is 100
Let W be the event that a student walked to school
So P(w) = 10/100 = 0.1
Let S be the event that a student is a senior
P(S) = 35/100 = 0.35
The probability we want to calculate can be said to be;
Probability that a student walked to school given that he is a senior
This can be represented and calculated as follows;
P( w| s) = P( w n s) / P(s)
w n s is the probability that a student walked to school and he is a senior
We need to know the number of seniors who walked to school
From the table, this is 5/100 = 0.05
So the Conditional probability is as follows;
P(W | S ) = 0.05/0.35 = 0.1429
To the nearest hundredth, that is 0.14
