We can use similar triangles to solve this. The bigger triangle is made up of the water tower as the height and the long horizontal line as its base, and the smaller triangle fitted inside the larger is made up of the tripod of the camera as the height and the distance Brian lies on the ground beyond it as the base for that triangle. We have to add this distance to the distance of the larger triangle's base. Setting it up as a proportion:

[tex]\frac{watertower}{base} =\frac{camera}{base}[/tex]

but since everything is in different measurements, we have to sort that out first. Let's change everything to feet.

The water tower's distance is 100 yards + 2 feet 9 inches:

Assuming that the rates are constant, we can see that Tom can paint the fence in 7.5 hours.

Here we will use equations of the form:

We know that Chuck can paint a fence in 5 hours, then if C is the rate (assuming this is constant), we can write:

C*5 hours = 1 fence

C = (1/5) fences per hour.

And let's say that Tom's rate is T.

When they work together, the rate is:

(C + T)

And they can paint the fence in 3 hours, then:

(C + T)*3 hours = 1 fence

Replacing the value of T we will get:

( 1/5 fences per hour + T)*3 hours = 1 fence

1/5 fences per hour + T = 1/3 fences per hour.

T = (1/3 - 1/5) fences per hour

The true statement is Option B, The midpoint Riemann sum approximation overestimates the definite integral.

Given data,

In this case, since the function f changes from increasing to decreasing and the graph of f changes from concave up to concave down, we can infer that the function has a local maximum point within the interval [1, 3].

The midpoint Riemann sum approximation for the definite integral breaks the interval [1, 3] into four subintervals of equal width, and it uses the midpoint of each subinterval to approximate the value of the function within that subinterval.

Now, when the function is increasing, the midpoint Riemann sum approximation will tend to underestimate the value of the definite integral since it approximates the function using values that are smaller than the actual function values.

However, when the function changes from increasing to decreasing, the midpoint Riemann sum approximation will tend to overestimate the value of the definite integral since it approximates the function using values that are larger than the actual function values.

Since 2023^2023 = 2023 * 2023 * ... * 2023 (2023 times), we can see that the factors of 2023^2023 are simply the powers of 2023.

Given that the first two balls are green and yellow respectively, the probability that the third ball drawn is green is 2/5. The final answer is (3/7) * (4/6) * (2/5) = 24/245.

(b) There are several ways to order 2 green and 1 yellow ball, such as green-green-yellow or green-yellow-green. The total number of such combinations is C(3,2) * C(4,1) = 3 * 4 = 12. The probability of getting any of these combinations is (3/7) * (2/6) * (4/5), so the total probability is 12 * (3/7) * (2/6) * (4/5) = 72/245.
