Answer:
E. 396/538
Step-by-step explanation:
The probability that the senior selected will not be from High School B given that the senior did not answer colege:
First, what's the probability of not having answered college? This will be out denominator.
P(not choosing college) = 244 + 106 + 188 = 538
Next, what's the probability that a senior in that category is not from HS B? Well, add the probabilities that the senior is in HS A or C:
P(senior is in HS A or C and answered not college) = 49 + 99 + 63 + 83 + 31 + 71 = 396
<u>Our answer is E. 396/538.</u>
Answer:
P = 4x + 10
Step-by-step explanation:
perimeter of a rectangle = 2( width + length )
P = 2 ( x - 2 + x + 7 )
P = 2 ( x + x + 7 - 2 )
P = 2 ( 2x + 5 )
P = 4x + 10
Mean - add up all of the scores, and divide it by the number of members:
68 + 62 + 60 + 64 + 70 + 66 + 72 = 462
462 / 7 = 66
ANSWER: The mean is 66
Median - write out all the numbers in order, and select the middle value:
60, 62, 64, 66, 68, 70, 72
ANSWER: As you can see, 66 is the middle value.
Midrange - find the mean (average) of the smallest and largest number:
Largest number: 72
Smallest number: 60
Midrange: 72 + 60 = 132
132 / 2 = 66
ANSWER: So the midrange is 66

Answer:
1. $4
2. 1/4 or .25 pints
3. 5 pints
4. $32
Step-by-step explanation:
1. $12/3= $4
2. 1/$4= 1/4 or .25 of a pint
3. $20/$4 = 5 pints
$. 8x$4 = $32
