Answers

Answer 1

The lines in the diagram can be categorized as follows: Lines l and m: parallel or none of these. Lines l and n: perpendicular or none of these.

Lines l and m: To determine if they are perpendicular, parallel, skew, or none of these, we need to examine their orientation. If lines l and m have the same slope, they are parallel. If their slopes are negative reciprocals of each other (i.e., the product of their slopes is -1), then they are perpendicular. If neither of these conditions is met, we cannot definitively classify them.

Lines l and n: Similarly, we need to assess the relationship between lines l and n. If their slopes are negative reciprocals of each other, they are perpendicular. Otherwise, if their slopes are the same or if one of the slopes is undefined (vertical line), they are none of these (neither parallel nor perpendicular).

question a circle has a radius of 21 inches. what is the length of the arc intercepted by a central angle that measures 4π7 radians? express the answer in terms of π . enter your answer in the box.

Answers

The length of the arc is given by (4π/7) times the circumference of the circle. Hence, the length of the arc intercepted by a central angle of 4π/7 radians in a circle with a radius of 21 inches is 12π inches.

The circumference of circle is given by the formula C = 2πr, where r is the radius of the circle. In this case, the radius is 21 inches. Therefore, the circumference of the circle is C = 2π(21) = 42π inches.

The central angle of 4π/7 radians is a fraction of the full angle (2π radians). The ratio between the central angle and the full angle is (4π/7)/(2π) = 2/7.

To find the length of the intercepted arc, we multiply the ratio 2/7 by the circumference of the circle:

Length of arc = (2/7) * (42π) = 12π inches.

Hence, the length of the arc intercepted by a central angle of 4π/7 radians in a circle with a radius of 21 inches is 12π inches.

Find the F-test statistic to test the claim that the variances of the two populations are equal. Both distributions are normal. The populations are independent. The standard deviation of the first sample is 4.8329
5.8304 is the standard deviation of the second sample.

Answers

The F-test statistic is approximately 1.455.

To find the F-test statistic to test the claim of equal variances for two populations, you need the standard deviations of both samples. Given that the standard deviation of the first sample is 4.8329 and the standard deviation of the second sample is 5.8304, we can proceed with the calculation.

The F-test statistic is calculated as the ratio of the variances of the two samples. In this case, since we only have the standard deviations, we need to square them to obtain the variances.

First, square the standard deviations:

Variance of the first sample (s1^2) = (4.8329)^2 = 23.3747

Variance of the second sample (s2^2) = (5.8304)^2 = 34.0051

Next, calculate the F-test statistic by dividing the larger variance by the smaller variance:

F-test statistic = (larger variance) / (smaller variance)

F-test statistic = s2^2 / s1^2

F-test statistic = 34.0051 / 23.3747

Using the given values, the F-test statistic is approximately 1.455.

An equation of a line in point-slope form:  y - y₁ = m(x - x₁)

1.

passes through (1, 9)   ⇒   x₁ = 1,  y₁ = 9

slope: m = 2

The equation:

y - 9 = 2(x - 1)          ←  point-slope form      

y - 9 = 2x - 2           {add 9 to both sides}

y = 2x + 7                ←    slope-intercept form  

2.

passes through (4, -1)   ⇒   x₁ = 4,  y₁ = -1

slope: m = -3

The first 5 terms of the arithmetic sequence are: 5, 9, 13, 17, 21.

Here we have an arithmetic sequence, such that the recursive formula is:

[tex]a_n = a_{n- 1} + 4[/tex]

Such that:

a₁ = 5.

Using that formula we can get the next 4 terms. For the second term we use n = 2, so we get:

[tex]a_2 = a_1 + 4 = 5 + 4 = 9[/tex]

For the third term we have:

[tex]a_3 = a_2 + 4 = 9 + 4 = 13[/tex]

For the fourth term we have:

[tex]a_4 = a_3 + 4 = 13 + 4 = 17[/tex]

For the fifth term we have:

[tex]a_5 = a_4 + 4 = 17 + 4 = 21[/tex]

A claim investigating company that investigates illegal claims suspects that the number of claims per major city filed is exceeding the past average of 70 claims, with standard deviation of 8.9. Suppose the company surveys 100 major cities and finds the average number of claims per city to be 71.8. At a significance level of = 0.05, test to determine if this sample data supports the company's suspicion?

Answers

The sample data does support the company's suspicion that the number of claims is exceeding the past average.

The company can use a "One-Sample T-Test" to determine if the sample data supports its suspicion. Under the null hypothesis, it is assumed that the mean number of claims per major city is still the previously established population mean of 70.

We can then calculate the test statistic:

T-test statistic = (71.8-70)/(8.9/√100)

= 1.8/0.8931

= 2.02

We can then compare this statistic to the critical value at an alpha level of 0.05. With n=100, and a two-sided test, this value is 1.645.

Because 2.02 > 1.645, we can reject the null hypothesis that the mean number of claims is still 70.

Therefore, the sample data does support the company's suspicion that the number of claims is exceeding the past average.

Answers

The magnitude of the resultant force, given two forces represented by vectors a and b with magnitudes 5.3 N and 6.9 N, respectively, and an angle of 60 degrees between them, can be approximated to 8.5 N.

To find the magnitude of the resultant force, we can use the law of cosines. According to the law of cosines, the magnitude of the resultant force (Ir) can be calculated using the formula: [tex](Ir)^2 = |a|^2 + |b|^2[/tex] - [tex]2|a||b|cos(theta)[/tex], where |a| and |b| represent the magnitudes of vectors a and b, and theta is the angle between them.

Given that |a| = 5.3 N, |b| = 6.9 N, and theta = 60 degrees, we can substitute these values into the formula and solve for Ir. Plugging in the values, we have [tex]Ir^2 = (5.3)^2 + (6.9)^2[/tex]- 2(5.3)(6.9)cos(60).

Simplifying the equation, we get [tex]Ir^2[/tex] = 28.09 + 47.61 - 36.66. Combining the terms, we have [tex]Ir^2[/tex] = 39.04.

Taking the square root of both sides, we find Ir ≈ √39.04 ≈ 6.2 N. Rounded to one decimal place, the magnitude of the resultant force is approximately 8.5 N.

Step-by-step explanation:

From the given table,

A. The unit rate for each car is,

Car A = [tex]\frac{416}{13}[/tex]

          = 32 miles per gallon

Car B = [tex]\frac{544}{16}[/tex]

          = 34 miles per gallon

Car C = [tex]\frac{665}{19}[/tex]

          = 35 miles per gallon

Car D = [tex]\frac{775}{25}[/tex]

          = 31 miles per gallon

B. From the derived values in A, the car that uses the least amount of gas is Car C.

C. Total distance covered = 496 miles x 4

                                           = 1984 miles

The gallons of gas the Car A would need for the journey can be determined by;

Car A requires 1 gallon for 32 miles

So that for 1984 miles = [tex]\frac{1984}{32}[/tex]

                                    = 62 gallons

Car A would need 62 gallons of gas to make the trip.

D. Amount spent on gas for Car A = $2.12 x 62

                                          = $131.44

E. speed = [tex]\frac{distance}{time}[/tex]

⇒ time = [tex]\frac{distance}{speed}[/tex]

Given the for Car A, speed = 68 miles per hour.

time = [tex]\frac{1984}{68}[/tex]

       = 29.1765

time = 29 hours

It would take approximately 29 hours for Car A to cover the total distance of 1984 miles.
