Hello,
There are a lot of polynomials which have 2 and 1/3 as zeroes,
I can show you one below
hope this helps
Solution:
Given that, 6 identical toys weigh 1.8 kg
we know that, 1kilogram = 1000 grams
6 identical toys weigh in grams
6 identical toys weigh 1800 grams
then calculating the weight of 1 toy by unitary method ,
weight of 1 toy =
grams.
Hence, 1 toy would weigh 300 grams.
Answer: A C and E (1st choice)
Step-by-step explanation:
Answer: range= 26, variance= 80 and standard deviation= 8.94
Step-by-step explanation:
Range = highest - lowest
Range = 146 - 120
Range= 26
Let m be mean
M=mean=sum/n
Mean=(120+134+146+127+138+133) / 6
M=798/6
M=133
The standard deviation sample formula:
S.D = sqrt( Summation of |x-m|^2 / n-1)
Let start finding:
|x-m|^2
For 1st: |120-133|^2=169
For 2nd: |134-133|^2=1
For 3rd: |146-133|^2=169
For 4th: |127-133|^2=36
For 5th: |138-133|^2=25
For 6th: |133-133|^2=0
Summation of |x-m|^2 = 400
The standard deviation formula is :
S.D = sqrt( Summation of |x-m|^2 / n-1)
S.D= sqrt(400 / 5)
S.D=sqrt(80)
S.D= 8.94
Variance = (Summation of |x-m|^2 / n-1)
Variance= 400/5
Variance= 80
