Answer:
Step-by-step explanation:
1.)1,2,3,4,5
mean=sum of all values/number of values
=1+2+3+4+5/5
=15/5
mean=3
Mode :
In the given data, no observation occurs more than once.
Hence the mode of the observations does not exist, means mode=0.
Median
1,2,3,4,5
Middle value is 3 so the median is 3.
2.)2,3,4,5,6,6
mean=sum of all values/number of values
=2+3+4+5+6+6/6
=26/6
mean =4.33
Mode
is that value of the observation which occurs maximum number of times so here mode is 6.
Median
2,3,4,5,6,6
4+5/2
9/2
median=4.5
3.)6,7,5,4,5,6,2,5
mean=sum of all values/number of values
=6+7+5+4+5+6+2+5/8
=40/8
mean =5
Mode
is that value of the observation which occurs maximum number of times so here mode is 5
Median
2,4,5,5,5,6,6,7
5+5/2
10/2
median=5
Answer: -3
Step-by-step explanation:
-4 +
can be written as x
which is the same as 2
Also , can be written as x , which is the same as 5
Substituting into the main question , we have
-4 (2 ) + 5
= -8 + 5
= -3
Answer:
x=5
Step-by-step explanation:
What three consecutive integers have a sum of 63? Which means that the first number is 20, the second number is 20 + 1 and the third number is 20 + 2. Therefore, three consecutive integers that add up to 63 are 20, 21, and 22.
Answer:80?
Step-by-step explanation:
20(2x2) =80
