You know we can't draw it, but I will give you all information so that to enable you draw this parabola
y = (x-4)² +3.
1-The coefficient of x =1 so it's positive, the parabola passe by a minimum or opens upward
2- It doesn't intercepts the x-axis since it has no zero value
3- its shifted 3 units upward & shifted 4 units to the right
4- its axis of symmetry is x=4 & its minimum is at (-3 , 3)
Hope this will help
3/4 with the main number divide it
Answer:
a(bc)=(ab)c
Step-by-step explanation:
here it is
2(3a+4)=6a+8 demonstrates the distributive property.
Let m be mean
Mean= sum/ n
Mean= (1720+1687+1367+1614+1460+1867+1436) / 7
m= 11151 / 7
M= 1593
Mean= 1593
Standard deviation
|x-m|^2
For 1st: |1720-1593|^2=8836
For 2nd: |1687-1593|^2=10201
For 3rd: |1367-1593|^2=51076
For 4th: |1614-1593|^2=441
For 5th: |1460-1593|^2=1689
For 6th: |1867-1593|^2=75076
For 7th: |1436-1593|^2=24649
Summation of |x-m|^2 = 171968
Standard deviation sample formula is:
S.D = sqrt((summation of |x-m|^2) / n-1)
S.D=sqrt(171968/6)
S.D=sqrt(28661.33)
S.D=169.30
Standard deviation is 169.30
