Step-by-step explanation:
Answer:
x = -4, y = 8.
Step-by-step explanation:
Question 16.
8x + y = -24 ........(A)
-3x - 2y = -4 ........(B)
Multiply (A) by 2:
16x + 2y = -48 Adding this to equation (B):
13x = -52
x = -4
Substituting this value of x in Equation (A):
8(-4) + y = -24
y = -24 + 32 = 8.

The Mean is the value of all the numbers in a data set added together and divided by the amount of numbers there are for example the mean of the set 2,5,8,9 is 6.
The median is the middle values of all the numbers. If there are 2 medians, you usually have to add them both and divide by 2 to get the actual median
The mode is the number(s) that show up the most in the data set. for example, the mode of the data set 2,2,3,4,4,4,6,9 is 4, because it is repeated 3 times.
hope this helped!
Find the mean, median, mode for 41,41,41,42,42,43,43,43,43,45,45,45,46,46,46,46,46,46,46,49,49,50,51,51,53,54,55,55,56,56,57

Answer:
Mean : 47.48
Median : 46
Mode : 46
Step-by-step explanation:
1) Mean= Total sum / Total Entries
Sum = 41*3 +42*2+43*4+45*3+46*7+49*2+50*1+51*2+53*1+54*1+55*2+56*2+57*1
Sum = 123+84+172+135+322+98+50+102+53+54+110+112+57
sum = 1472
Total Entries = 3+2+4+3+7+2+1+2+1+1+2+2+1= 31
Mean = 1472/31
= 47.48
ii) Median = 16th Value
As there are total 31 entries , Hence the Median will be the entry coming on 16th place
Median = 46
iii) Mode
The entry which is repeated for the maximum number of times is called the mode. Here 46 is repeated the most. hence 46 is the mode
