Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).

A.
57=3\cdot19\\
96=2^5\cdot3
Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.

143=11\cdot13\\
323=17\cdot19

Indeed, those two numbers are relatively prime.

Can a object that measures 1.8 metres by 1.2 metres fit in a gap that measure 1 metre by 0.75 metres
Paha777 [63]
No it cannot because 1.8 and 1.2 are both larger than 0.75 so there is no physical way for it to fit

a bag has a total of 120 notes in denominations of rs 2, rs. 5 and rs. 10. the total value of the notes in the bag is rs 760. if
Deffense [45]
So there are three variables, rs2 label x, rs5 label y, rs10 label z
Lets write equeations using these variables. 
x+y+z=120  (<span>A bag has a total of 120 notes)
2x+5y+10z=760  (total value)
2x+5*2y+10z=960  (twice as many rs5)

3 variables, 3 independent equations will give solution. There are a fair few ways to solve this. </span>

The line plot (shown in the attached image) shows the prices of sunglasses at a department store.
Andru [333]

a. The median is 70, the mode is 60, and the mean is 70.8.

b. Mean best captures the data.

c. When there are outliers, the mean might be a deceptive center measure.

Calculating the Mean, Median, and Mode

Mean: Total number of sunglasses / total quantity of pries

Mean = (20 + 20 + 50 + 50 + 50 + 60 + 60 + 60 + 60 + 60 + 60 + 70 + 70 + 70 + 80 + 80 + 80 + 80 + 90 + 90 + 90 + 90 + 100 + 100 + 130) / 25

Mean = 70.8

Median is equal to the (n/2 + 1)th term.

The number of sunglasses in this case is n.

(25/2 + 1)th term as the median

Median = 13th term

Median is 70

Mode is  the most frequent data

Therefore, mode = 70

Why is mean the most appropriate central measure ?

The mean is often the ideal measure of central tendency to use when your data distribution is continuous and symmetrical, such as when your data are normally distributed. So, mean here denotes the typical cost of the sunglasses.
