610 times three equals 1830.
1830 plus 305 equals
Answer:
2135 miles
Step-by-step explanation:
ok so the plane is going at a speed of 610 mph
1 hour = 610 miles
this is a whole break down of what goes on in my head
610 x 3.5 = ?
600 x 3 = 1800
600 x .5 = 300
10 x 3 = 30
10 x .5 = 5
1800 + 300 + 30 + 5 = 2135
the plane will fly 2135 miles in 3.5 hours

(i) A person borrowed Rs. 16000 from a bank at 12.5% per annum simple interest for 3 years and but he loans the whole amount to a shopkeeper at the same rate of compound interest for the same time.
(a) Find the amount to be paid to the bank as simple interest.
(b) Find the amount to be get to the shopkeeper as compound interest.
(c) How much will he gain after 3 years?
The person will gain Rs. 5,500 after 3 years by lending the whole amount to a shopkeeper at the same rate of compound Interest for the same time.
Given, Principal amount (P) = Rs. 16,000
Rate of Interest (R) = 12.5%
Time (T) = 3 years(a)
The amount to be paid to the bank as simple interest can be calculated as follows:
Simple Interest (SI) = (P × R × T) / 100= (16000 × 12.5 × 3) / 100= Rs. 6,000Therefore, the amount to be paid to the bank as simple interest is Rs. 6,000.
(b) The amount to be received by the person from the shopkeeper as compound interest can be calculated as follows: Compound Interest (CI) = P × [1 + (R/100)]T – P= 16000 × [1 + (12.5/100)]3 – 16000= Rs. 21,500
Therefore, the amount to be received by the person from the shopkeeper as compound interest is Rs. 21,500.(c) Gain = CI - P= 21500 - 16000= Rs. 5,500
Therefore, the person will gain Rs. 5,500 after 3 years by lending the whole amount to a shopkeeper at the same rate of compound interest for the same time.

Please do not try to do this by hand, but use the functions in Excel. · Find the Confidence Interval for your data. Sample initial post: First find the mean and standard deviation.
Then put this in an excel cell =confidence.norm(0.5,stdev,samplesize) and hit enter. This is the E value. (Note: please use your standard deviation and sample size and not the words.)
Set up your confidence interval: (mean-E, mean+E)
Formula you used above for the confidence interval:
The formula is E= zsubc * sigma / sqrt n
Where the left hand endpoint is xbar - E and the right hand endpoint is xbar + E
The mean of the given fuel prices data set is $4.61 with a standard deviation of $1.62.
To calculate the mean and standard deviation in Excel, you can use the following functions:
Mean: The AVERAGE function calculates the mean of a range of values. In this case, enter "=AVERAGE(A1:A30)" in an Excel cell, assuming the data is in cells A1 to A30.
Standard Deviation: The STDEV.S function calculates the standard deviation of a range of values. Enter "=STDEV.S(A1:A30)" in an Excel cell to calculate the standard deviation of the data set.
Using the mean ($4.61) and standard deviation ($1.62), we can now proceed to calculate the Confidence Interval.
The Confidence Interval can be determined using the formula: E = Z * (σ / √n)
In the formula, Z is the z-score corresponding to the desired level of confidence (e.g., 95% confidence corresponds to a z-score of approximately 1.96), σ is the population standard deviation (which can be estimated using the sample standard deviation in this case), and n is the sample size.
Let's assume we want a 95% confidence interval for the data set with a sample size of 30. We can use the formula "=CONFIDENCE.NORM(0.05, STDEV, 30)" in an Excel cell to calculate the E value.
Substituting the values into the formula, we get E = 1.96 * (1.62 / √30) ≈ 0.595.
Now, we can set up the confidence interval using the mean and E value:
Confidence Interval = (mean - E, mean + E)
Confidence Interval = ($4.61 - $0.595, $4.61 + $0.595)
Confidence Interval = ($4.015, $5.205)
Therefore, the 95% Confidence Interval for the given fuel prices data set is approximately $4.015 to $5.205.
In summary, the mean of the fuel prices data set is $4.61 with a standard deviation of $1.62. The 95% Confidence Interval for the data is approximately $4.015 to $5.205.

A cone-shaped paper drinking cup is to be made to hold 36 cm^3 of water. Find the height and radius of the cup that will use the smallest amount of paper. (Round your answers to two decimal places.)
height 4.10 cm
radius ____ cm
A cone-shaped paper drinking cup is to be made to hold 36 cm^3 of water. In order to make the paper cup with the least amount of paper, we need to minimize the surface area of the cone.
We want to minimize the surface area of the cone, which is given by:S = πr(r + s)where s is the slant height of the cone. We can eliminate s by using the Pythagorean theorem: s^2 = r^2 + h^2hence: s = sqrt(r^2 + h^2)
Now, we can substitute this into the surface area formula: S = πr(r + sqrt(r^2 + h^2)) = πr^2 + πr(sqrt(r^2 + h^2))
To minimize the surface area, we need to find the values of r and h that satisfy the volume equation and minimize the surface area equation. We can do this by using the method of Lagrange multipliers. The Lagrangian function is: L = πr^2 + πr(sqrt(r^2 + h^2)) + λ[(1/3)πr^2h - 36] Taking partial derivatives with respect to r, h, and λ and setting them equal to zero gives: 2πr + (πh r)/(sqrt(r^2 + h^2)) + (2/3)πλr^2 = 0πr/(sqrt(r^2 + h^2)) + (1/3)πλr^2 = 0(1/3)πr^2h - 36 = 0 Solving this system of equations gives:r = 1.85 cm h = 4.10 cmλ = 0.57 cm^-1
Therefore, the radius of the paper cup that uses the smallest amount of paper is 1.85 cm. The height of the paper cup that uses the smallest amount of paper is given as 4.10 cm. The radius of the paper cup that uses the smallest amount of paper is found to be 1.85 cm.

A 20-foot ladder leans up against the side of a building so that the foot of the ladder is 10 feet from the base of the building. If specifications call for the ladder's angle of elevation to be between 35 and 45 degrees.
Given the information above, sketch out the scenario. Determine if the placement of this ladder satisfies safety specifications. Then, explain why or why not it would meet the safety specifications using at least 3 complete sentences.
Answer:
Step-by-step explanation:
Note that the base of the building forms a right angle with the ground and the ladder forms a right triangle with the building.
On this case, we can apply Pythagorean theorem.
Since the ladder serves as the hypotenuse and the distance from the base of the building to the foot of the ladder is adjacent with the angle of elevation, we can use cosine.
Let A be the angle of elevation
cos A = adjacent/hypotenuse
cos A = 10ft/20ft
cos A = 0.50
A = Arc cos 0.50
A = 60°
With the given data, the angle of elevation turns out to be 60°. As it's beyond the allowable values, it won't satisfy the safety specifications of 35°-45°. The placement of the ladder is too steep and would need to be adjusted.

The five-number summary for scores on a statistics exam is: 35, 68, 77, 83 and 97. In all, 196 students took this exam About how many students had scores between 68 and 83?
The five-number summary consists of the minimum value, the first quartile, the median, the third quartile, and the maximum value.
The interquartile range is the difference between the third and first quartiles. Interquartile range (IQR) = Q3 – Q1, where Q3 is the third quartile and Q1 is the first quartile. The 5-number summary for scores on a statistics exam is given below:
Minimum value = 35
First quartile Q1 = 68
Median = 77
Third quartile Q3 = 83
Maximum value = 97
The interval 68–83 is the range between Q1 and Q3.
Thus, it is the interquartile range.
The interquartile range is calculated as follows:IQR = Q3 – Q1 = 83 – 68 = 15
The interquartile range of the scores between 68 and 83 is 15. Therefore, the number of students with scores between 68 and 83 is roughly half of the total number of students. 196/2 = 98.
Thus, the approximate number of students with scores between 68 and 83 is 98.Answer: a. 98

Ms. Armstrong purchased a car for $20,000. After 4 years, the car was only worth $8,000. Write an equation in slope intercept form that can be used to find the value of the car y, after x number of years.
Answer:
$20,000=4x
Step-by-step explanation:
First if we want to find out how much the price of the car went down we would have to find out how much the price went down by subtracting $20,000 by $8,000. I got 12,000. Then we have to find out how much the price went down every year. So, $12,000 ÷ 4 = $3,000. So, in 4 years the price went down $3,000 dollars every year

escribe how relative frequencies of past events are used to predict future events. (for example, if a student passed seven out of ten assignments in a course, what do you think is the probability that this student will pass the next assignment in the course? how did you calculate this probability?)
Relative frequencies of past events can be used to predict future events by using probability theory. Probability theory is a branch of mathematics that deals with the study of random phenomena.
In the given example, if a student passed seven out of ten assignments in a course, the probability that the student will pass the next assignment in the course can be calculated by using relative frequency. We can use the formula of probability to calculate the probability of the student passing the next assignment. Probability is calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes.
In this case, the number of favorable outcomes is seven because the student passed seven out of ten assignments. The total number of possible outcomes is ten because the student attempted ten assignments. Therefore, the probability of the student passing the next assignment is 7/10 or 0.7. This means that there is a 70% chance that the student will pass the next assignment.
In conclusion, the relative frequency of past events can be used to predict future events. Probability theory can be used to calculate the probability of an event occurring in future events. By using the formula of probability, we can calculate the probability of an event occurring based on the relative frequency of past events. In the given example, the probability of the student passing the next assignment is calculated as 0.7 or 70%.
