It's C because you change 2/5 into 4/10 then you add 4/10+4/10 which equals 8/10 and is 1 mph. So you add another 2/10 which is an half of a half which equals 1/4. So C
Answer:The answer is
and the number in green box =7
Step-by-step explanation:
P(Sophomore| Girl)=?
We have P(A | B) =P(A∩B)/ P(B)
P(Sophomore∩Girls)= 
Total Students =8+12+5+5 =30
Total girls =4+7+3+4 =18
P(Girls)=
P(Sophomore | Girl)=P(Sophomore | Girls)/P(Girls)
=
=
The number in green box =7
Answer:the answer is 33
Step-by-step explanation:
The attached diagram represents the tree diagram for three consecutive mornings.
<h3>How to draw the tree diagram?</h3>
The probability of arriving on time is given as:
P(On Time) = 65%
Assume that the bus would definitely show up.
Then it means that the event is a binomial event and the possible outcomes are:
On Time and Late
The above means that the number of possible outcomes is 2.
For three consecutive mornings, the total outcome is:
Total = 2³
Evaluate
Total = 8
This means that the tree diagram would have 8 outcomes
Next, we draw the tree diagram (see attachment)

Answer:
95k
Step-by-step explanation:
Given :
15 words or less = 50k
Every word above 15 = additional 3k
The cost of 30 words :
First 15 words = 50 k
Number of additional words = (30 - 15) = 15 words
Cost of every additional word = 3 k
Cost of 15 additional word = 15 * 3 = 45k
Total cost of 30 words :
50k + 45k = 95k
