Step-by-step explanation:

Step 1 :

Given data set - 14,18,20,21,25,32,40,44,48

We need to get the 3rd quartile

Step 2 :

To find the quartile's , we have to divide the data set into 4 equal quarters.

The 3rd cut will give the 3rd quartile

Step 3:

The median of this data set is at 25, there are 4 numbers below and above it.

Now we take the 2nd half of the set , after the median and take the median of it.

There are 4 numbers in the 2nd half 32,40,44,48. Cutting this into 2 , we have the cut to fall between 40 and 44. Hence taking the average of this will give the 3rd quartile.

The average of 40 and 44 is 42 .

Hence the 3rd quartile is 42.

J. Reexamine the sequence 20, 14, 8, 2, ... from the problem

DENIUS [597]

Answer:

The n th of the given sequence is $t_{n} = 26-6 n$

Step-by-step explanation:

Step 1 :-

Given sequence is 20,14,8,2,.......this sequence in arithmetic progression but this sequence is decreasing sequence.

given first term is 20 and difference is $d = second term- first term = 14-20=-6$

now the nth term of given sequence is

by using formula $t_{n}=a+(n-1)d$

$t_{n}= 20+(n-1)(-6)$

$t_{n}= 20-6 n+6$

final answer:-

$t_{n} = 26-6 n$

verification:-

$t_{n} = 26-6 n$

put n=1 we get first term is 20

put n=2 we get second term is 14

put n=3 we get third term is 8

put n=4 we get fourth term is 2

so the n th term of sequence is

$t_{n} = 26-6 n$

Brian budgeted $1,000.00 for a new computer. Will give brainly and extra points

yanalaym [24]

Answer:

Brian can purchase the laptop, but not the desktop computer

Step-by-step explanation:

Percentages

We'll evaluate two options for Brian's purchase of a new computer. The first option is to purchase a laptop with a price of $1,100. The laptops have a 15% discount. Let's compute the price of the laptop after the discount is applied:

Original price: 1,100

Discount: 15% = 15*1,100/100=165

Final price: $935

With a budget of $1,000, Brian can purchase the laptop.

Now we'll analyze the option of purchasing the desktop computer valued at $1,365 with a discount of 25%:

Original price: 1,365

Discount: 25% = 25*1,365/100=341.25

Final price: $1023.75

With a budget of $1,000, Brian cannot purchase the desktop computer.

Answer: Brian can purchase the laptop, but not the desktop computer
