a taxi driver charges a fixed rate of r to pick up a passenger.in addition, the taxi driver charges a rate of m for each mile driven.write a formula to represent t, the total amount this taxi driver will charge for a trip of n miles

Answers

The formula is: t = r + mn. This represents that the total (t) is the fixed rate (r) plus the charge per mile (m) for the number of miles (n).

The weights of tennis balls are normally distributed, with the mean being 5.15 ounces and the standard deviation being 0.10. what percentage of the balls weigh within one standard deviation of the mean? 50% 68% 95% 99.7%

Answers

68% percentage of the balls weigh within one standard deviation of the mean. Option b is correct.

The weights of tennis balls are normally distributed, with the mean being 5.15 ounces and the standard deviation being 0.10. what percentage of the balls weigh within one standard deviation of the mean to be determined.

What is the empirical rule?

Empirical Rule is defined as an elongation of the prior reading Understanding the Normal Distribution. In the prior reading, the aim was to develope an instinct of the relations between lowered probability and expanded distance from the mean.

Since, from the empirical rule, it can be said that 68% percent of the balls weigh within one standard deviation of the mean because Approx 68% of the data occurs within 1 Standard Deviation of the mean.

Thus, 68% percentage of the balls weigh within one standard deviation of the mean. Option b is correct.

The formula for the volume of a cylinder is V = πr2h. The volume of a cylinder is three times the volume of a cone with the same radius and height. If the volume of a cone with the same height as a cylinder equals the volume of the cylinder, the equation for the radius of cone R in terms of the radius of cylinder r is

Answers

Since the cone volume formula is V=1/3πr2h , and the volume of a cylinder is V=πr2h , the ratio of cone to cylinder 3/1 or 3 : 1

Jade invested $13,500 at 5.2% interest, compounded semiannually, and she wants to know how much her investment will be worth in 8 years
Part 1: What is the periodic interest rate of jade investment
Part 2: How many compounding periods does jades investment offer in a year? how about in 8 years?

Answers

Part 1: What is the periodic interest rate of jade investment?

Each compounding period is done semi-annually, which means twice a year. Since the given interest rate is annual, then 5.2% divided by half should yield the period interest rate, which is 2.6%

Part 2: How many compounding periods does Jade's investment offer in a year? how about in 8 years?

In 1 year, there are 2 compounding periods. In 2 years, there are 16 compounding periods.

Answer:

Part 3: What expression can Jade write to figure out how much her investment will be worth in 8 years? F = $13,500.00 * (1 + .052/2) ^ (2*8)

Part 4: How much will Jade's investment be worth in 8 years? $20,355.96
