Express the confidence interval (0.065,0.143) in the form of p - E
Answers
The confidence interval expressed in the form p - E is:
(0.104 - 0.039, 0.104 + 0.039).
What are the mean and the margin of error of a confidence interval?The mean is the mean of the bounds, hence:
p = (0.065 + 0.143)/2 = 0.104.
The margin of error is the difference between the bounds and the mean, hence:
E = 0.104 - 0.065 = 0.143 - 0.104 = 0.039.
Hence the interval in the desired format is:
(0.104 - 0.039, 0.104 + 0.039).

Answers
c) Mode: 15 (appears 6 times)
Mean: 15.25
Median: 15
d) Probability of being 13 years old: 2/20 = 0.1 or 10%
e) Probability of being 14 or 16 years old: 6/20 = 0.3 or 30%
f) Probability of not having 15 years old: 1 - (6/20) = 14/20 = 0.7 or 70%
a) To create a table and calculate the absolute frequency, relative frequency, and percentual frequency, we organize the given ages in ascending order:
13 13 14 14 15 15 15 15 15 16 16 17 17 17 18 18
Age Absolute Frequency Relative Frequency Percentual Frequency
13 2 2/16 12.5%
14 2 2/16 12.5%
15 5 5/16 31.25%
16 2 2/16 12.5%
17 3 3/16 18.75%
18 2 2/16 12.5%
b) To represent the data graphically with a histogram, we plot the ages on the x-axis and the absolute frequency on the y-axis:
c) To calculate the mode, mean, and median:
Mode: The mode is the most frequently occurring age in the dataset. In this case, the mode is 15, as it appears 5 times.
Mean: The mean is the average of all the ages. To calculate it, we sum up all the ages and divide by the total number of ages:
(13 + 13 + 14 + 14 + 15 + 15 + 15 + 15 + 15 + 16 + 16 + 17 + 17 + 17 + 18 + 18) / 20 = 306 / 20 = 15.3
Median: The median is the middle value in the dataset when arranged in ascending order. In this case, the median is 15 since it falls in the middle.
d) To calculate the probability of having 13 years old, we divide the absolute frequency of 13 (2) by the total number of ages (20):
Probability of 13 years old = 2/20 = 0.1 or 10%
e) To calculate the probability of having 14 or 16 years old, we add the absolute frequencies of 14 and 16 (2 + 2 = 4) and divide by the total number of ages (20):
Probability of 14 or 16 years old = 4/20 = 0.2 or 20%
f) To calculate the probability of not having 15 years old, we subtract the absolute frequency of 15 (5) from the total number of ages (20):
Probability of not having 15 years old = (20 - 5)/20 = 0.75 or 75%

Answers
The equation is 2.90 + 1.25m= 6.65
The number of miles in the taxi ride is 3 miles
How to calculate the number of miles in the taxi ride ?
The airport charged a pick up fee of $2.90
$1.24 was charged per mile
The total fare was $6.65
The equation can be expressed as
2.90 + 1.25m= 6.65
collect the like terms
1.25m= 6.65 - 2.90
1.25m= 3.75
divide by the coefficient of m which is 1.25
m= 3.75/1.25
m= 3

In the figure, m∠4=74°
and m∠3=43°
. Find m∠1
and m∠2
.
Answers
Answer:
Based on the information given, we know that angles 3 and 4 are supplementary (they add up to 180 degrees) and angles 2 and 4 are vertical angles (they are congruent). Therefore, we can write:
m∠4 + m∠3 = 180 (since angles 3 and 4 are supplementary)
m∠4 = m∠2 (since angles 2 and 4 are vertical angles)
Substituting m∠4 = m∠2 into the first equation, we get:
m∠2 + m∠3 = 180
Now we can solve for m∠2 and m∠3:
m∠3 = 43 (given)
m∠2 = 180 - m∠3 = 180 - 43 = 137
Since angles 1 and 2 are also supplementary, we can find m∠1 by subtracting m∠2 from 180:
m∠1 = 180 - m∠2 = 180 - 137 = 43
Therefore, m∠1 = 43 degrees and m∠2 = 137 degrees.

Show that C is the image of A by dilation with center B and ratio 3.
Answers
We have shown that C is the image of A by dilation with center B and ratio 3.
Now, To show that C is the image of A by dilation with center B and ratio 3, we need to follow these steps:
Firstly, Find the vector AB by subtracting the coordinates of B from the coordinates of A:
AB = A - B = (6 - 3, 4 - 7) = (3, -3)
Multiply the vector AB by the dilation ratio of 3:
3 AB = 3 (3, -3) = (9, -9)
Add the resulting vector to the coordinates of the center B:
BC = B + 3 AB = (3, 7) + (9, -9)
BC = (12, -2)
Hence, Compare the resulting point BC to the coordinates of C to show that they are the same:
BC = (12, -2) = C
Therefore, we have shown that C is the image of A by dilation with center B and ratio 3.

You're writing a book about a $3,030 bike race across the United States. You wonder about a title, and how many pedal strokes it takes to finish the race. Assuming a pedal stroke is about 16 ft on average which of the following would be the best title?
Answers
Answer:
I hope that helped.
Step-by-step explanation:
We have that a mile is equal to 5280 feet. Hence the whole distance is 15.998.400 feet in distance. Since every 16 feet we have one stroke, we have to divide the distance by 16 to get the number of strokes. The result is 999.900 strokes. Hence, if one wants to be accurate, the correct title is "999.900 pedal strokes". For poeticness though, maybe the best title is "1 million pedal strokes".
The pedal strokes it takes to finish the race is 999.900 pedal strokes.
It is required to find the pedal strokes it takes to finish the race.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
we know that
1 mile =5280 feet.
Hence the whole distance is 15.998.400 feet in distance.
Since every 16 feet we have one stroke,
we have to divide the distance by 16 to get the number of strokes.
strokes=15.998.400 feet/16
strokes=999.900 strokes
The result is 999.900 strokes.
Hence, if one wants to be accurate, the correct title is "999.900 pedal strokes".
Therefore, the pedal strokes it takes to finish the race is 999.900 pedal strokes.

How many days must past before it becomes probable that Janice will have had to pick up lunch at least once?

Note that the probability of any of the staff at the office picking the food is 1/8.
