IQR= 18 is the interquartile range of his scores.
1/2 hour = 105 miles
Divide by 1/2 on both sides :
1/4 hour = 52.5 miles
The total cost of the customers order is s/2 + 1.50 dollars.
<u>Explanation:</u>
Let s represent the cost of sandwich
Cost of pretzels = 1.50 dollars
Special offer by deli lunch = Half of the cost of sandwich + bag of pretxel
Cost of offer. = s/2 + 1.50 dollars
Original order = 1 sandwich
Originial cost = s dollars
Answer:
-279
Step-by-step explanation:
a=64
d=t2-t1=57-64=-7
t50=a+49d=64+49×(-7)
=64-343
=-279
No, this is not normal
This is a binomial distribution. Use BINS to determine if this is binomial.
B - binary?
I - independent?
N - number of trials
S - probability of success
B - yes, 3 or not a 3
I - yes, past rolls do not impact future rolls
N - 20 trials
S - prob success 1/6
Use binompdf on your calculator to find out the probability. To access, 2nd —> vars —> binompdf
Binompdf(20 (trials), 1/6 (p), 11 (x)) = 8.97x10^-5
The probability to roll a 3 11 times is .0000897. The chances are very low, making this not normal.
