Answer:
0.6
Step-by-step explanation:
Given: Mean= $750
Standard deviation= $60
First, lets find out z-score of the interval between $624 and $768.
z score=
z score=
∴ z score for $624 is -2.1
Now, finding z score for $768
Z score=
∴ z score for $768 is 0.3
As per the z score table, the value for -2.1 is 0.0179 and for 0.3 is 0.6179
Now, subtracting the value to get proportion
∴ There are 0.6 proportion of laptops are in the range of $624 and $768
Let
Then
Quadratic means 2nd degree
means highest power of variable is 2
c(x)=6x+3x^3
3rd degree, not quadratic
d(x)=x-8x^4,
4th degree, not quadratic
p(x)=-5x-x^2
2nd degree, it's quadratic
k(x)=2x^2+9x^4
4th degree, not quadratic
answer is
