There are two circles with centers A and D.

The tangent line touches both points B and C.

The given measurements are enough to solve for the missing value and the solution is shown below:

Solve for the measurement of AC which the hypotenuse of legs AB and BC by Pythagorean theorem:

Solve for angle of A

sin A=26/27.51

Answer:

10 miles

Step-by-step explanation:

Let's call the number of miles driven in a day "x". The total cost for Triangle Truck Rental can be expressed as:

Cost (Triangle) = $35 + 0.5x

The total cost for Circle Rent-A-Truck can be expressed as:

Cost (Circle) = $55 + 0.3x

We want to find the value of x such that Cost (Triangle) = Cost (Circle). So we can set the two expressions equal to each other and solve for x:

$35 + 0.5x = $55 + 0.3x

0.2x = $20

x = 100 miles

So the man would need to drive 100 miles in one day for both companies to have the same total cost.

Probability of an event = (number of favorable event) / (total number of event).

P(B) = (Event B) / (total number of event).

Probability of getting 1 = 1/6.

Rolling dice is an independent event, it is not dependent on how many times it’s been rolled.

Probability of getting 1 three times in a row = probability of getting 1 first time × probability of getting 1 second time × probability of getting 1 third time.

Probability of getting 1 three times in a row = (1/6) × (1/6) × (1/6) = 1/216.

Hence, the probability of getting 1 three times in a row is 0.463%.

The standard error of a statistic or an estimate of a parameter is the standard deviation of its sampling distribution.

The standard deviation of the sample distribution is referred to as the standard error in statistics. In most cases, the sample mean of a data set differs from the actual population mean. SE is used to denote it. It is used to gauge how well a sample of a population represents that population. Data, samples and populations, means, medians and modes, dependent and independent variables, standard deviations, variance, and other concepts are all covered in the large field of statistics.

The standard error is one of the mathematical tools used in statistics to estimate variability. It is abbreviated as SE. The standard error of a statistic or an estimate of a parameter is the standard deviation of its sampling distribution. We can define it as an estimate of that standard deviation.

The order of the rectangular area from greatest to least is green sticker > yellow sticker > red sticker

The area of a rectangle is calculated by multiplying its length by its width. So if the length of a rectangle is l and the width is w, then its area A is given by the formula A = l x w.

To solve this problem, we can find the area of each sticker one after the other.

Area = length * width

1. red sticker = 2 * 1.5 = 3cm²

2. green sticker = 12 * 0.5 = 6cm²

3. yellow sticker = 3 * 1.25 = 3.75cm²

2) The monthly payment for 12 installments is $87.50.

The total cost of the item is based on the downpayment's equivalent percentage (proportion).

A proportion is the equation of two or more ratios.

Finance Charge (Interest) = $100

Downpayment = $50 or 5%

Installment period = 12 months

Cost of item = $1,000 ($50/5%)

The total interest charges after 30 years with an APR of 3.4 % is given by the equation A = $ 77,550.80

The annual percentage yield (APY) is the real rate of return earned on an investment, taking into account the effect of compounding interest. An APR is a number that represents the total yearly cost of borrowing money, expressed as a percentage of the principal loan amount.

Given data ,

Let the total interest charges after 30 years be represented as A

Now , the equation will be

The APR percentage = 3.4 %

The amount taken as loan = $ 130,000

The number of years = 30 years

The monthly payment = $ 576.53

The number of payments n = 30 x 12 = 360 payments

So , the total amount paid in 30 years = monthly payment x number of payments

Substituting the values in the equation , we get

The total amount paid in 30 years = 360 x 576.53

The total amount paid in 30 years = $ 207,550.80

Now , the total interest charges after 30 years A = total amount paid in 30 years - amount taken as loan

Substituting the values in the equation , we get

The total interest charges after 30 years A = $ 207,550.80 - $ 130,000

On simplifying the equation , we get

The total interest charges after 30 years A = $ 77,550.80

Hence , the interest charges after 30 years is $ 77,550.80

Answer:

40 hours

26.09 hours

Step-by-step explanation:

What is the driving time for a ​1800-mile trip if you drive at an average speed of 45 miles per​ hour?

1800 / 45 = 40 hours

What is the driving time at 69 miles per​ hour?

1800 / 69 = 26.09 hours

Step-by-step explanation:

The driving time for a 1800-mile trip at an average speed of 45 miles per hour can be calculated as

Driving time = Total distance / Average speed

Driving time = 1800 miles / 45 miles per hour = 40 hours

Similarly, the driving time at an average speed of 69 miles per hour can be calculated as:

Driving time = 1800 miles / 69 miles per hour = 26 hours

So if you drive at an average speed of 45 miles per hour, the driving time for a 1800-mile trip would be 40 hours, and if you drive at an average speed of 69 miles per hour, the driving time would be 26 hours.

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

The sample variance and standard deviation are given as follows:

Variance = 87.22 %.

Standard deviation = 9.34%.

To obtain the variance and the standard deviation first, we must obtain the mean, which is given by the sum of all observations divided by the number of observations, hence:

Mean = (77.1 + 82.9 + 90 + 91.3 + 81.9 + 83.3 + 84.9 + 82.5 + 84.6)/10

Mean = 75.85.

Then we must obtain the sum of the differences squared between each observation and the mean, as follows:

(77.1 - 75.85)² + (82.9 - 75.85)² + (90 - 75.85)² + (91.3 - 75.85)² + (81.9 - 75.85)² + (83.3 - 75.85)² + (84.9 - 75.85)² + (82.5 - 75.85)² + (84.6 - 75.85)² = 784.9825

The sample variance is given by the above sum divided by one less than the sample size, hence:

Variance = 784.9825/9

Variance = 87.22 %.

The standard deviation is the square root of the variance, hence:

Standard deviation = sqrt(87.22)

Standard deviation = 9.34%.
