Answer:
The given statement is false.
Step-by-step explanation:
We are given the following in the question:
95% confidence interval: (4.53,5.18)
Sample mean, 
= 4.85 seconds
Sample size, n = 20
Alpha, α = 0.05
Sample standard deviation, σ = 1.47 seconds
Degree of freedom = n - 1 = 19
95% Confidence interval:
Putting the values, we get,
Thus, the calculated confidence interval is different from the given confidence interval.
Hence, the given statement is false.
Simply plug g and h into the equation:
g + h =
(-7) + (3) = -4

If tan(<span>θ) is negative, then </span><span>θ must be either in Q-II or else in Q-IV.
Fortunately, the question tells us that it's in Q-II.
If you draw a circle on the x- and y-axes, then draw a right triangle
in Q-II, then mark the legs 3 and -2, then the hypotenuse of the
triangle ... also the radius of the circle ... is √13 .
Look for the angle whose tangent is -3/2.
tangent = (opposite) / (adjacent)
So the side opp</span>osite is the 3 and the side adjacent is the -2.
For that same angle, cosine = (adjacent) / (hypotenuse) .
The adjacent side is still the -2, and the hypotenuse is √13 .
So the cosine of the same angle is
- 2 / √13 .
To rationalize the denominator (get that square root out of there),
multiply top and bottom by √13 . Then you have
(- 2 / √13) · (√13 / √13)
= - 2 √13 / 13 .
Answer:
r = 5m
Step-by-step explanation:
miles walked money earned
0 0
1 1*5 5
2 2 * 5 10
3 3 * 5 15
4 4 * 5 20
5 5 * 5 25
6 6 * 5 30
We multiply 5 by each mile walked to determine how much money was raised
r = 5m where r is the money raised and m is the miles walked
