Yes, because they are equal and have the same measurement same size and same shape.
Answer:
3271
Step-by-step explanation:
so in the number there are four numbers
the 3 is in the thousands so it goes first
the 2 second
the 7 third
and the 1 last
<span>h(x)=4x2−7x−17
a get like this:
</span>h(x)=f(x)−g(x) =6x2−3x−9-(2x2+4x+8)=6x2−3x−9-2x2-4x-8=4x2−7x−17
Answer:
It is 91.01 m/s faster than the Singaporean sprinter
Convert km/hr to m/s
U get 101.38m/s (speed of bullet train)
Speed of the Singaporean sprinter is 10.37m/s
So subtracting the train speed from the sprinter's speed,
101.38 - 10.35= 91.01m/s
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
