Answer: Lower Quartile= 21

Upper Quartile = 52

Interquartile range =31

Step-by-step explanation:

The given data : 45, 21, 3, 15, 32, 97, 68, 27, 29, 52.

Arrange in order ,

3, 15, 21, 27 , 29 ,32 , 45 , 52 , 68 , 97

Lower half = 3, 15, 21, 27 , 29

Upper half = 32 , 45 , 52 , 68 , 97

Lower Quartile $(Q_1)$ = Median of Lower half of data

$Q_1= 21$ [Median is the middle most term.]

Upper Quartile $(Q_2)$ = Median of Lower half of data

$Q_3= 52$ [Median is the middle most term.]

Interquartile range = $IQR= Q_3-Q_1$

$=52-21=31$

Answer: 11.05

Step-by-step explanation:

Divide 5.20 by 8 to find the price of each bag (which is .65 cents.) Multiple .65 by 20 (13). 15% of 13 is 1.95. 13 - 1.95 is 11.05

PS: 1.95 is the discount. Hope this helps. Have a good day.

The number of text messages sent daily by a student is a poisson random variable with parameter λ=5 .in a class with 20 independ

Rudik [331]

This problem is a combination of the Poisson distribution and binomial distribution.

First, we need to find the probability of a single student sending less than 6 messages in a day, i.e.
P(X<6)=P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)+P(X=5)
=0.006738+0.033690+0.084224+0.140374+0.175467+0.175467
= 0.615961

For ALL 20 students to send less than 6 messages, the probability is
P=C(20,20)*0.615961^20*(1-0.615961)^0
=6.18101*10^(-5) or approximately
=0.00006181

A total of 430 tickets were sold for the school play . They were either adult tickets or student tickets . There were 70 fewer s

Maurinko [17]

So first we assume that half is adult and have is student.

So
215 adult 215 student

Now since it said they were 70 less student tickets than adult tickets we subtract 70.
215 - 70 = 145

Now we add the 70 we subtracted from student tickets to the adult tickets.
215 + 70 = 285

So there were
285 adult tickets sold and 145 student tickets sold

I hope this helped. Have a great day!
