3/5 is the answer. Difference means to subtract
Answer:
P(a junior or a senior)=1
Step-by-step explanation:
The formula of the probability is given by:

Where P(A) is the probability of occurring an event A, n(A) is the number of favorable outcomes and N is the total number of outcomes.
In this case, N is the total number of the students of statistics class.
N=18+10=28
The probability of the union of two mutually exclusive events is given by:

Therefore:
P(a junior or a senior) =P(a junior)+P(a senior)
Because a student is a junior or a senior, not both.
n(a junior)=18
n(a senior)=10
P(a junior)=18/28
P(a senior) = 10/28
P(a junior or a senior) = 18/28 + 10/28
Solving the sum of the fractions:
P(a junior or a senior) = 28/28 = 1
Find total area
area=pir^2
d/2=r
12=d, 12/2=6=r
area=pi6^2=36pi, pi=3.14
area=113.04 square inches
22 per square inch
113.04 times 22=2486.88
rounded
2487 calories
Answer:
e^xsinx · (sinx+xcosx)
Step-by-step explanation:
f'(x)=e^xsinx · (xsinx)'= e^xsinx · (sinx+xcosx)

<h2><<< In this case, the mode is 9 seconds. The median is the middle number in a list of numbers ordered from smallest to largest. so 10 is the median of this set of results. The range is the difference between the lowest value and the highest value, so the range here is 15 - 9 = 6. </h2>
