The approximate latitudinal distance of cities Rochester and Richmond is 394 miles

Let us assume the angle between the 2 cities as θ

θ = 43.2° - 37.6°

  =5.7°

hence for finding the latitudinal distance between the cities (given that the Earth is approximately spherical) we can use the formula

distance= [tex]\frac{\theta}{360} *2\pi r[/tex]

             = [tex]\frac{5.7}{360} *2 (3.14)(3960)[/tex]

             = 393.756 miles ≈394 miles

a) The expected annual rainfall accumulated in this lake is 30 million tons. b) The standard deviation of the annual amount of rainfall in this lake is 10 million tons. c) P(X < 4) = 0.3085. d) P(2 < X < 5) = 0.4293.

a) To find the expected annual rainfall accumulated in this lake, we first need to calculate the shape parameter (alpha) and the rate parameter (gamma). alpha = 3 and gamma = 5. Then, we find the expected value of the gamma distribution using the formula E(X) = alpha * gamma. This gives us E(X) = 3 * 5 = 15. Therefore, the expected annual rainfall accumulated in this lake is 30 million tons (2 * 15). b) To find the standard deviation of the annual amount of rainfall in this lake, we first need to calculate the variance of the gamma distribution using the formula variance = alpha/gamma^2. This gives us variance = 3/25 = 0.12. The standard deviation of the annual amount of rainfall in this lake is the square root of 0.12, which is 0.346. This is equivalent to 10 million tons (2 * 0.346). c) To find P(X < 4), we can use the R programming language. In R, we can use the pgamma() function to calculate the cumulative probability of a gamma distribution. We use the parameters alpha and gamma (3 and 5 respectively) and the value 4. This gives us P(X < 4) = 0.3085. d) To find P(2 < X < 5), we can use the R programming language. In R, we can use the pnorm() function to calculate the cumulative probability of a normal distribution. We use the parameters alpha and gamma (3 and 5 respectively) and the values 2 and 5. This gives us P(2 < X < 5) = 0.4293.

The value of the bond if the rate of interest currently is 6% the value of the bond is Rs. 1,000 and if it is 8% it is 750

Now, According to the question:

A bond is a sort of financial instrument where the issuer (debtor) owes the holder (creditor) a debt and is required, based on the terms, to pay the creditor cash flow at the bond's maturity date as well as interest over a certain period of time. The interest is often due annually, semi-annually, and on occasion less frequently. Bonds give the borrower access to external capital for momentary investments or, in the case of government bonds, for the financing of ongoing expenses. Despite the fact that both bonds and stocks are securities, bondholders hold a position as a creditor and stockholders hold equity in a firm. The main distinction between the two is this.

The correct representation of the sentence 15 is what percent of 40 is 15 is 37.5% of 40.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

The algebraic representation of the statement 15 is what percent of 40 is:

40 (x/100) = 15

40x / 100 = 15

40x = 1500

x = 1500/40

The average rate of change over the interval 15 ≤ x ≤ 30 is equal to -6/5.

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function f(x) over the interval [15, 30]:

a = 15; f(a) = 40

b = 30; f(b) = 22

For the average rate of change over the interval 15 ≤ x ≤ 30, we have the following:

Average rate of change = [f(b) - f(a)]/(b - a)

Average rate of change = [22 - 40]/(30 - 15)

Average rate of change = -18/15

The faster train would be travelling at 120 mph.

Let's give the slower train's speed the designation of x mph. The speed of the speedier train would then be x + 10 mph.

The 4.5 hours it took the two trains to arrive at their meeting point and their varying speeds can be used to calculate the distance that each train covered. The relative speed is equal to the product of the velocities of the two trains,

Therefore (x) + (x + 10) = 2x + 10 mph.

Distance = rate x time gives the distance covered by each train.

The slower train's route can be expressed as follows:

x * 4.5 hours = 495 miles.

Additionally, the quicker train covered 495 miles in (x + 10) * 4.5 hours.

We can now use these two equations to solve for x:

x * 4.5 = 495

The Typewriters should be guaranteed for 7.72 months, which would give a 5% chance of requiring a major repair before the end of the guarantee period.

Typewriter repair times have a normal distribution, with a mean of 11 months and a standard deviation of 2 months. To find the warranty period at which only her 5% of typewriters fail before the warranty expires, we need to find the corresponding z-score and solve it after the warranty period.

Using the standard normal distribution table, we find that the Z-score corresponding to a cumulative probability of 0.95 is approximately 1.64.

This means that 95% of typewriters will need major repairs after 11 + 1.64 * 2 = 14.28 months.

To ensure that only 5% of typewriters fail before the warranty expires, the warranty period should be set to 11 - 1.64 * 2 = 7.

72 months.

Finally, the typewriter still has about 7.72 months of warranty, and only 5% of cars fail before the warranty runs out.

Two sails are similar triangles.

So the angles of two sails are equal and the corresponding sides are proportional.

We can write the relation as,

x / 30 = x- 2 / 26 = y + 9 / 5y - 3

Consider x / 30 = x- 2 / 26.

Cross multiplying,

26x = 30(x - 2)

26x = 30x - 60

-4x = -60

x = 15

Consider x / 30 = y + 9 / 5y - 3.

Substituting x = 15,

15 / 30 = y + 9 / 5y - 3

Answer:

The perimeter of triangle FGL is unknown.

The equation of line segment AB is y = 3.5x - 0.5.

Line segment AB starts at point A(-1, -3) and ends at point B(3, 11). The equation for this line can be found by calculating the slope and then using the point slope formula, y-y1=m(x-x1).

The slope of the line is m= (11-(-3)) / (3-(-1)) = 14/4 = 3.5.

Using the point-slope formula, we can find the equation of the line:

y-(-3) = 3.5(x-(-1))

y + 3 = 3.5x + 3.5

y = 3.5x - 0.5
