Compare the population range to the mean of the sample ranges. Choose the correct answer below A. The population range not equal t0 the mean of the sample ranges (it is also not equal to the age of tne oldest ofiicia or age of the youngest official at the time of death). B. The populalion range equal the youngest official at Ihe time of death and the mean of the sample ranges is equal to the oldest official at the time ol doath C. The populalion range equal t0 Ihe mean of the sample ranges_ D. The population range I5 equa the age the oldest otficial at the time of death and the mean of the sample ranges equal to Ihe youngest olficlal at the time of death
By comparing the population range to the mean of the sample ranges, the answer will be D) The population range equal the youngest official at the time of death and the mean of the sample ranges is equal to the oldest official at the time of death.
Creating a tonne of random numbers between 40 and 70 points so that we can see that the population range is equal to 70. That is presumably the oldest value that is still valid. The population range is the sum of the data generated at the highest level and the lowest level. The population range is now 30 points. by taking a handful of random samples.
We want a sample table containing random samples of the data so we don't have to worry about this. Going through the samples with the new table that will be generated here and want to find this range by taking the max of each sample. Subtracting the mean from each sample from the range samples from 1 to 10. The range for the initial data was 30 points because the entire range was 40 to 70 points; nevertheless, we can observe that this range varies from 64 to 70 points.
We made the table because we wanted the mean of the average of our separate ranges to be 21.7. The mean value of the ranges in 100 samples will be discovered if the sample size is increased. A sample's range is not representative of the population. We can infer that we do it since the samples' range and average range are greatly dissimilar.

How to evaluate the arithmetic series?
An arithmetic progression ( AP ) is a sequence of numbers such that the difference between the consecutive terms is constant.
From the given information, we can get the first term (a) and last term (l) of the sequence by substituting n = 1 and n = 45 respectively into the given expression, (4n + 9). That is:
a = 4(1) + 9 = 13
l = 4(45) + 9 = 189
Sum of all terms in a finite AP with the first term (a) and last term (l) is given by:
S = n/2(a + l)
S = 45/2 (13+189) = 4545
Thus, the arithmetic series evaluates to

The original value for the first angle so that the angle measures form a triangle is 39.5°
Interior angles of a triangleFor any triangle to be formed, its three interior angles must sum up to 180°. Thus the sum of the interior angles of a triangle is 180°
Considering, the angles: 115.1°, 47.5° and 93°, their sum which is 255.6° is not equal to 180° so they cannot form a triangle.
but a new value represented by x for the first angle 115.1° can be derived as follows;
x + 47.5° + 93° = 180°
x + 140.5 = 180° {subtract 140.5° from both sides}
x = 180° - 140.5°

One ticket cost $6, and two tickets for a couple cost $10. You sold 196 tickets and gained $1076. How many couples bought tickets?
Answer:
How many couples bought tickets?
50
Step-by-step explanation:
s + 2c = 196 Eq. 1
6s + 10c = 1076 Eq, 2
s = single tickets
c = couple tickets
From Eq. 1:
s = 196 - 2c Eq. 3
Replacing Eq. 3 in Eq. 2:
6(196-2c) + 10c = 1076
(6*196 + 6*-2c) + 10c = 1076
(1176 - 12c) + 10c = 1076
1176 - 2c = 1076
1176 - 1076 = 2c
100 = 2c
c = 100/2
c = 50
From Eq. 3:
s = 196 - 2c
s = 196 - 2*50
s = 196 - 100
s = 96
Check:
From Eq. 2:
6s + 10c = 1076
6*96 + 10*50 = 1076
576 + 500 = 1076

To pay for a home improvement project that totals $16,000, Genesis is choosing between taking out a simple interest bank loan at 8% for 3 years or paying with a credit card that compounds monthly at an annual rate of 15% for 7 years. Which plan would give Genesis the lowest monthly payment?
The monthly credit card payment would be $511.11, which is lower than the monthly payment on the bank loan.
The monthly payment on a bank loan would be $480, which is lower than the monthly credit card payment.
The monthly payment on a bank loan would be $551.11, which is lower than the monthly credit card payment.
The monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.
Answer: The monthly payment on a bank loan would be $480, which is lower than the monthly credit card payment.
To calculate the monthly payment on the bank loan, we can use the formula:
monthly payment = P * (r / (1 - (1 + r)^(-n)))
where P is the total loan amount, r is the annual interest rate as a decimal, and n is the number of months of the loan.
For a loan of $16,000 at 8% interest for 3 years (36 months)
r = 0.08/12 = 0.0067
n = 36
P = 16000
So, the monthly payment = 16000 * (0.0067 / (1 - (1 + 0.0067)^(-36))) = 480
To calculate the monthly credit card payment, we can use the formula:
M = P * r * (1 + r)^n / [(1 + r)^n - 1]
where P is the total loan amount, r is the monthly interest rate, and n is the number of months of the loan.
For a credit card with an annual rate of 15% for 7 years (84 months)
r = 0.15/12 = 0.0125
n = 84
P = 16000
So, the monthly payment = 16000 * 0.0125 * (1 + 0.0125)^84 / [(1 + 0.0125)^84 - 1] = 511.11
As we can see the monthly payment on the bank loan is lower than the monthly credit card payment. So, the correct answer is "The monthly payment on a bank loan would be $480, which is lower than the monthly credit card payment."

Given are the distance - time (x{t}) and the velocity - time, (v{t}) graphs as shown in the image.
We can conclude for each part of the graph as -
{A} →The object is moving in the forward direction at a constant velocity.
{B} →The object is not moving.
{C} →The object is slowing down in the backward direction.
{D} →The object is changing directions.
{E} →The object is speeding up in the forward direction.
Therefore, the answers to each part of the labelled graph is given above.

What is the equation of the line that is parallel to the line y = x + 4 and passes through the point (6, 5)?
y = x + 3
y = x + 7
y = 3x – 13
y = 3x + 5
Answer:
most appropriate is y=3x - 13 but it is not the correct one.comparing y=3x-13 with y=mx+c the we get,m(slope)=3 whereas comparing y=X+4 with y=mx +c,we get m(slope)=1.But the slopes of parallel lines are always equal.
The correct equation for the line is y=X -1.

Put the following in order from least to greatest:
0.25, 1/3, 30%
Answer: 0.25 30% 1/3
Step-by-step explanation:
1/3 is the largest because when made in a decimal it would be 3.3 reapeting, 30 % is 0.3 and 0.25 . So the order will be 0.25 30% and 1/3.
