Answer:
The constant of variation is 3
Step-by-step explanation:
Given.
And y is directly related to x
∝
Here k is constant of variation
--------------(1)
Put the and
value in equation 1.
So, the constant of variation is 3.

Answer:
D. The equation has a variable multiplied by itself. A squared variable.
Step-by-step explanation:
A quadratic equation will always start with a term being squared. For example, + 5x + 7 = 44. Another example would be
+ 2x - 10 = 12. These are just random numbers, but the equation will always look the same! Hope this helps!
Let p be the proportion. Let c be the given confidence level , n be the sample size.
Given: p=0.3, n=1180, c=0.99
The formula to find the Margin of error is
ME =
Where z (α/2) is critical value of z.
P(Z < z) = α/2
where α/2 = (1- 0.99) /2 = 0.005
P(Z < z) = 0.005
So in z score table look for probability exactly or close to 0.005 . There is no exact 0.005 probability value in z score table. However there two close values 0.0051 and 0.0049 . It means our required 0.005 value lies between these two probability values.
The z score corresponding to 0.0051 is -2.57 and 0.0049 is -2.58. So the required z score will be average of -2.57 and -2.58
(-2.57) + (-2.58) = -5.15
-5.15/2 = -2.575
For computing margin of error consider positive z score value which is 2.575
The margin of error will be
ME =
=
= 2.575 * 0.0133
ME = 0.0342
The margin of error is 0.0342
