Answer:
(-3, 9), (-1, 11), (0, 12), (4, 16), (6, 18)
Step-by-step explanation:
The function definition tells you that adding 12 to the x-value will give you the value of f(x).
-3 +12 = 9, for example
The (x, f(x)) values for the table are shown above.
Answer: Margin of Error = 1.944
Lower Bound = 3.052
Explanation:-
Attached below is a file for monthly Rate of return. Used an excel sheet to determine the confidence interval which seems relatively easier as compared to manual computation. The range below (A2:A40) shows the monthly
Functions used : Standard Deviation as= STDEV (A2:A40)
Sample Mean = AVERAGE(A2:A40)
Margin of Error = CONFIDENCE.T(D4,D5,D2)
Lower Bound Interval = D6-D7 = -3.052
Answer:
x = -4
Step-by-step explanation:
<u>Step 1: Subtract 2x from both sides</u>
2x - 2 - 2x = 4x + 6 - 2x
<em>-2 = 2x + 6</em>
<em />
<u>Step 2: Subtract 6 from both sides</u>
-2 - 6 = 2x + 6 - 6
<em>-8 = 2x</em>
<em />
<u>Step 3: Divide both sides by 2</u>
-8 / 2 = 2x / 2
<em>-4 = x</em>
<em />
Answer: x = -4
Answer:
The answer is B and C
Step-by-step explanation:
Answer:
a
Step-by-step explanation:
Recall that the "point-slope" form of a linear equation may be expressed as
y = mx + b,
where m is the gradient.
If m is negative, the gradient is negative.
If m is positive, the gradient is positive.
In our case, if we consider option A,
x + 3y = -2 (rearranging)
3y = -x -2
y = (-1/3) x - (2/3)
if we compare this to the general equation at the top, we can see that
gradient, = m = (-1/3) which is negative.
hence option a has a negative gradient.
