Answer:
The margin of error for the confidence interval for the population mean with a 98% confidence level is 2.88 miles per hour.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
Find the margin of error for the confidence interval for the population mean with a 98% confidence level.

The margin of error for the confidence interval for the population mean with a 98% confidence level is 2.88 miles per hour.
Answer:
11.33 cups
Step-by-step explanation:
240 grams of carbohydrates: x
40 x + 4 x + 26 x = 240
X = 240/70
X = 3 3/7 cups
332 grams of fats = y
0y + 13y + 70y = 332
Y = 332/83
Y = 4 cups
207 grams of proteins = z
5z + 21z + 27z = 207
Z = 207/53
Z = 3 48/53 cups
3 3/7 + 4 + 3 48/53 = 11.33 cups
Answer:
The equation of the line would be y = 2x + 8
Step-by-step explanation:
In order to find the equation of the line, we first need to find the slope of the original line. We can do that by solving for y.
14x - 7y = 1
-7y = -14x + 1
y = 2x - 1/7
Now that we have a slope of 2, we know the new slope will be the same since parallel lines have the same slope. So we can use it along with the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 4 = 2(x + 2)
y - 4 = 2x + 4
y = 2x + 8
