Answer:

The best estimate of the mean of the population is 50,000 miles, which is the sample mean.

To make a better inference, we know that the 95% confidence interval for the mean is (49,306; 50,694).

Step-by-step explanation:

The unbiased point estimation for the population mean tread life is the sample mean (50,000 miles), as it is the only information we have.

Although, knowing the standard deviation, we can calculate a confidence interval to make a stronger inference.

We calculate a 95% confidence interval for the mean.

The population standard deviation is not known, so we have to estimate it from the sample standard deviation and use a t-students distribution to calculate the critical value.

The sample mean is M=50000.

The sample size is N=100.

When σ is not known, s divided by the square root of N is used as an estimate of σM:

\(s_M=\dfrac{s}{\sqrt{N}}=\dfrac{3500}{\sqrt{100}}=\dfrac{3500}{10}=350\)

The degrees of freedom for this sample size are:

\(df=n-1=100-1=99\)

The t-value for a 95% confidence interval and 99 degrees of freedom is t=1.98.

The margin of error (MOE) can be calculated as:

\(MOE=t\cdot s_M=1.98 \cdot 350=694.48\)

Then, the lower and upper bounds of the confidence interval are:

\(LL=M-t \cdot s_M = 50000-694.48=49306\\\\UL=M+t \cdot s_M = 50000+694.48=50694\)

The 95% confidence interval for the mean is (49306, 50694).

Using the inverse of the function from the table, the value of f⁻¹(4) is 107/3

The inverse of a function is a new function that "undoes" the original function. It reverses the mapping of inputs and outputs, allowing you to find the original input value when you know the output value.

In this problem, we have to use the table to find the original function which is f(x) and use it to find the inverse of the function;

Taking two points from the table;

m = y₂ - y₁ / x₂ - x₁

m = 0 - (-3) / -9 - (-11)

m = 3 / 20

Using the slope and one point on the table;

y = mx + x

-3 = 3/20(-11) + c

-3 = -1.65 + c

c = -3 + 1.65

c = -1.35

Putting the slope and y - intercept together;

y = 3/20x - 1.35

y = 3/20x - 27/20

f(x) = 3/20x - 27/20

Taking the inverse of the function;

f⁻¹(x) = (20x + 27)/3

To find the value of f⁻¹(4), we just need to substituting the value of x in the function;

f⁻¹(4) = (20(4) + 27)/3

f⁻¹(4) = 107/3

The volume of a rectangular box or basket can be calculated using the formula:

V = l x w x h

where l is the length, w is the width, and h is the height of the box or basket.

In this case, the height of the basket is 6 inches, the width is 4 inches, and the length is 12 inches. Therefore, we can substitute these values into the formula and calculate the volume:

V = l x w x h

V = 12 x 4 x 6

V = 288 cubic inches

Therefore, the volume of the rectangular basket is 288 cubic inches.

The volume of the basket is 288 cubic inches.

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

The volume of a rectangular prism can be calculated

Answer:

To calculate the percent increase in the amount of interest paid between a household with a 740 credit score and one with a 730 credit score , we need to find the total amount paid for each score and then calculate the percent increase.

From the given table , we can see that the simple interest rate for a credit score of 740-799 is 15%, and the total number of payments is 33 . So, the total amount paid for a principal balance of $18,000 with a credit score of 740 is:

Principal + Total Interest = Total Amount Paid

$18,000 + ($18,000 * 15% * 33/12) = $20,700

Similarly, for a credit score of 730, we need to use the simple interest rate for a credit score of 670-739 , which is 18%, and the total number of payments is 38. So, the total amount paid for a principal balance of $18,000 with a credit score of 730 is:

Principal + Total Interest = Total Amount Paid

$18,000 + ($18,000 * 18% * 38/12) = $21,240

Now, to calculate the percent increase in the amount of interest paid , we can use the following formula:

Percent increase = |(New value - Old value) / Old value| * 100%

Plugging in the values, we get:

Percent increase = |($21,240 - $20,700) / $20,700| * 100%

Percent increase = 2.6%

Rounding to the nearest tenth, we get the final answer as:

Percent increase = 2.6% ≈ 2.5%   (rounded to the nearest tenth)

Therefore, the answer is O 2.5%.

Step-by-step explanation:

100 people cuz 90% of 100 is 90

Answer:

The smallest sample size the company can take and still pass the large counts condition is 100 total customers.

Step-by-step explanation:

The large counts condition says that all expected counts need to be at least 5. The company needs to sample enough customers so that they expect each mode of payment to appear at least 5 times. Since the distribution they expects is uneven, we should look at the mode of payment that has the lowest expected percentage.

The lowest expected percentage is 5%, percent, which is the percentage of both cash and payment via smartphone, We need to pick a sample so 5%, percent of its size equals at least 5.

0.05x ≥5

x ≥100

So, the company needs to sample at least 100 customers.

Using the sine ratio, the value of the sine of angle C, to the nearest hundredth, is: 0.42.

The formula of the sine ratio of a reference angle in a given right triangle having one of its angles as angle 90 degrees (right angle) is expressed as: sin ∅ = length of opposite side / length of hypotenuse of the right triangle, where ∅ is the reference angle in the right triangle.

Given the following information about triangle BCD:

Angle D = 90° (right angle, this means triangle BCD is a right triangle)

Angle C = ∅ (reference angle, we are to find the value of its sine).

DC = 77 (adjacent side)

BD = 36 (opposite side)

CB = 85 (hypotenuse).

Apply the sine ratio to find the sine of ∠C:

sin C = 36/85

sin C = 0.4235

sin C = 0.42 (to the nearest hundredth).

Therefore, applying the sine ratio, the value of the sine of angle C, to the nearest hundredth, is: 0.42.

We must determine the percentage of the total area under the uniform distribution curve to the right of 3,814 pounds in order to determine the probability that a car will weigh more than 3,814 pounds.

Mathematicians use probability theory to determine the likelihood that an event will occur or a statement is accurate. A probability of essentially 0 shows how likely an occurrence appears to occur, while a risk is a number between 0 and 1, where 1 implies certainty.

(a) The average of the vehicle's lowest and highest weights, or (2,674 + 4,089) / 2, equals 3,382 pounds, is the mean weight of the vehicle. The mean weight is 3,382 when rounded to the closest whole number.

(b) The formula for calculating the standard deviation of a uniform distribution is (b - a) / 12, where a denotes the lowest value and b denotes the maximum value. We arrive at (4,089 - 2,674) / 12 = 408.4751 after substituting the numbers. The standard variation, rounded to four decimal places, is 408.475.

(c) We must determine the percentage of the total area under the uniform distribution curve that lies to the left of 2,961 pounds in order to determine the likelihood that a car will weigh less than 2,961 pounds. (2,961 - 2,674) / (4,089 - 2,674) = 0.33815 is the formula for this region. The chance, rounded to four decimal places, is 0.3381.

(d) We must determine the percentage of the total area under the uniform distribution curve to the right of 3,814 pounds in order to determine the likelihood that a car will weigh more than 3,814 pounds. (4,089 - 3,814) / (4,089 - 2,674) = 0.2904 gives the area of this triangle. The chance, rounded to four decimal places, is 0.2904.

By answering the presented question, we may conclude that One possible recursive sequence that could produce the sequence 5, -22, 86, ... is: a[1] = 5

In mathematics, a sequence is an ordered list of items. Elements can be numbers, functions, or other mathematical objects. A series is commonly expressed by putting the phrases in parentheses and separating them with commas. A natural number series, for example, can be denoted as: (1, 2, 3, 4, 5, ...) Similarly, the even number series is labelled as follows: (2, 4, 6, 8, 10, ...) A series can be finite or infinite depending on whether it has a finite or infinite number of words.

One possible recursive sequence that could produce the sequence 5, -22, 86, ... is:

a[1] = 5

a[n] = -4a[n-1] - 6n + 11

We can verify that this sequence generates the desired sequence by computing the first few terms:

a[1] = 5

a[2] = -4a[1] - 6(2) + 11 = -22

a[3] = -4a[2] - 6(3) + 11 = 86

a[4] = -4a[3] - 6(4) + 11 = -342
