A. The graph will be continuous because the amount of gas that she added to the tank does not need to be an integer amount.
Basically, we need to plug in the given values for the variables

and

into the given expression

. First off, we can plug in all the given values into the expression, giving us

. Now, perform the operations on the inside of the parentheses. Doing this, we get

. Now, we use the distributive property to simplify. This gives us

. Finally, when we add the two numbers, we get

. Hope this helped!
A. X ~ N(66, 6.25)
b.


Using a standard normal probability table to find probability values for the z-scores, we get:
P(65 < X < 69) = 0.1554 + 0.3849 = 0.5403
c. z= 0.524 and -0.524

1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4
Answer:
see below
Step-by-step explanation:
6+9x^2
Rewriting in decreasing powers of x
9x^2 +0x + 6
ax^2+bx+c
a = 9
b =0
c = 6
Answer:
The domain is (2,5,-3,0)
Step-by-step explanation:
we know that
For a set of ordered pairs, the first elements of each ordered pair represents the domain of the function and second elements of each ordered pair represents the range of the function.
The domain of a function is the set of all possible values of x
In this problem we have
![A= \ [(2,3), (5,1).(-3,-2), (0, 3)\ ]](https://tex.z-dn.net/?f=A%3D%20%5C%20%5B%282%2C3%29%2C%20%285%2C1%29.%28-3%2C-2%29%2C%20%280%2C%203%29%5C%20%5D)
therefore
The domain is (2,5,-3,0)
