Step-by-step explanation:

C = 0.75 + L

For L = 3 ; Cost, C = 3.75

3.75 = 0.75 + 3L

3.75 - 0.75 = 3L

3 = 3L

L = 3/3

L = $1

C = 0.75 + 1L

If amount spent is $10.75; C = 10.75

10.75 = 0.75 + L

10.75 - 0.75 = L

10 = L

Answer:

Option B: 26cm is the radius of smaller circle.

Step-by-step explanation:

Given that:

Ratio of circumferences of two circles = 2:3

We know that circumference of circle is given by 2πr.

Radius of larger circle = \(r_{2}\) = 39 cm

Radius of smaller circle = \(r_{1}\)

Now,

\(\frac{2\pi r_1}{2\pi r_2}=\frac{2}{3}\\\frac{r_1}{r_2}=\frac{2}{3}\)

Putting radius of larger circle

\(\frac{r_1}{39}=\frac{2}{3}\\\\r_1=\frac{2}{3}*39\\\\r_1=26\)

Therefore,

The radius of smaller circle is 26cm.

Hence,

Option B: 26cm is the radius of smaller circle.

The given statement "the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring." is False.

The union of two events A and B represents the event that at least one of the events A or B occurs. The probability of the union of two events can be calculated using the formula:

P(A or B) = P(A) + P(B) - P(A and B)

On the other hand, the intersection of two events A and B represents the event that both events A and B occur. The probability of the intersection of two events can be calculated using the formula:

P(A and B) = P(A) * P(B|A)

where P(B|A) is the conditional probability of B given that A has occurred.

It is possible for the probability of the union of two events to be greater than the probability of the intersection of two events if the two events are not mutually exclusive.

In this case, the probability of both events occurring together (the intersection) may be relatively small, while the probability of at least one of the events occurring (the union) may be relatively high.

In summary, the probability of the union of two events occurring can sometimes be greater than the probability of the intersection of two events occurring, depending on the relationship between the events.

The probability of finishing the project in 63 days is relatively high at 72.57%. The standard deviation is also useful in determining the range of completion times and the likelihood of delays or early completion.

To answer the question, we can use the PERT formula which takes into account the optimistic time (O), pessimistic time (P), and most likely time (M) for completion. The formula is as follows: expected completion time = (O + 4M + P)/6.

Given that the expected completion time is 63 days, we can calculate the most likely time (M) using the formula:\(M = (O + 4M + P)/6 - (standard\:deviation)^{2/6}.\)

Substituting the values, we get M = 60 days.

Now, to find the probability of finishing the project in 63 days, we need to calculate the Z-score using the formula Z = (X - μ)/σ where X is the completion time we are interested in, μ is the expected completion time and σ is the standard deviation.

Substituting the values, we get Z = (63 - 60)/5 = 0.6. We can use a Z-table or calculator to find the probability that corresponds to this Z-score. The probability of finishing the project in 63 days is 0.7257 or 72.57%.

In conclusion, using the PERT formula and Z-score calculation, we can estimate the probability of finishing a project within a specific time frame. In this case, the probability of finishing the project in 63 days is relatively high at 72.57%.

The standard deviation is also useful in determining the range of completion times and the likelihood of delays or early completion.

To use logistic regression with a categorical dependent variable, at least one independent variable must be measured at the nominal or ordinal level.

Logistic regression is a statistical model used to predict categorical outcomes, typically binary outcomes (e.g., yes/no, success/failure). The dependent variable in logistic regression is categorical, representing different categories or classes. To predict this categorical outcome, independent variables (also known as predictors or features) are used. These independent variables can be of various types, such as continuous, ordinal, or nominal.

However, to properly apply logistic regression, it is necessary to have at least one independent variable that is measured at the nominal or ordinal level. This is because logistic regression models are designed to handle categorical data, and having such variables allows for the estimation of probabilities and the prediction of class membership based on the given independent variables.

Determine the probability of drawing either a king or a heart? write your answer as a reduced fraction.

There are four kings and thirteen hearts (including the king of hearts) in a regular 52-card deck of playing cards. To avoid counting it twice, we must deduct the king of hearts from the total number of hearts.

There are 4 + 12 = 16 cards, all of which are kings or hearts.

By dividing the number of cards in the deck that are either kings or hearts by the total number of cards in the deck, one may determine the likelihood of drawing one of these cards:

P=16/52 (king or heart)

By reducing the numerator and denominator by their largest common factor, which is 4, this fraction can be made smaller:

P = 4/13 (king or heart)

Therefore, there is a 4/13 chance of drawing either a king or a heart.

The t procedure should not be used when there is a large outlier in the data or when the distribution shows moderate skewness. In these circumstances, the t procedure may not provide accurate results.

The t procedure assumes that the data is normally distributed. However, it can still be used under certain deviations from normality. The t procedure is robust to small departures from normality, so in the case of moderate skewness (option A), it can still provide reasonably accurate results. Skewness refers to the asymmetry of the distribution, and if it is only moderately skewed, the t procedure can be used.

However, there are situations where the t procedure should not be used. One such circumstance is when there is a large outlier in the data (option C). An outlier is an extreme value that differs significantly from the other observations. Large outliers can have a significant impact on the results of the t procedure, as it is sensitive to extreme values. In such cases, using the t procedure may lead to biased estimates or incorrect inferences.

Additionally, the sample standard deviation being large (option D) does not necessarily make the t procedure inappropriate. The t procedure is designed to handle variability in the data, including cases with larger standard deviations. As long as the other assumptions of the t procedure, such as normality and independence, are met, it can still be used effectively.

In summary, the t procedure should not be used when there is a large outlier in the data or when the distribution shows significant skewness. These situations can undermine the assumptions of the t procedure and may lead to inaccurate results.

There are 231,178,650 ways to choose a 5-person committee consisting of 3 republicans and 2 democrats from the given group.

To calculate the number of ways to choose a 5-person committee consisting of 3 republicans and 2 democrats from a group of 55 republicans and 45 democrats, we can use the concept of combinations.

The number of ways to choose 3 republicans from a group of 55 can be calculated using the combination formula:

C(55, 3) = 55! / (3! * (55 - 3)!)

Similarly, the number of ways to choose 2 democrats from a group of 45 can be calculated using the combination formula:

C(45, 2) = 45! / (2! * (45 - 2)!)

To find the total number of ways to form the committee, we multiply these two combinations together:

Total number of ways = C(55, 3) * C(45, 2)

Calculating these values, we have:

C(55, 3) = 55! / (3! * (55 - 3)!) = 55! / (3! * 52!) = 234,135

C(45, 2) = 45! / (2! * (45 - 2)!) = 45! / (2! * 43!) = 990

Total number of ways = C(55, 3) * C(45, 2) = 234,135 * 990 = 231,178,650

Since angle y and angle x form vertical angles, the measure of angle x is equal to 50°.

In Geometry, the vertical angles theorem is also referred to as vertically opposite angles theorem and it states that two (2) opposite vertical angles that are formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other.

Furthermore, the sum of the angles on a straight line is equal to 180. Therefore, we would sum up all of the angles as follows;

60° + 70° + y = 180°

130° + y = 180°

y = 180° - 130°

y = 50°

Since both angle x and angle y are vertical angles, we can logically deduce that they are congruent and as such the magnitude of angle x is equal to 50°.

The perimeter of the polygon shown = AC + BC + AB

Using distance formula, calculate the distance formula, \( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \), calculate AC, BC, and AB.

The coordinates of the points are as follows,

A(3, 5),

B(0, 0)

C(6, 0)

Find AB:

\( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \)

Where,

A(3, 5) => (x1, y1)

B(0, 0) => (x2, y2)

\( AB = \sqrt{(0 - 3)^2 + (0 - 5)^2} \)

\( AB = \sqrt{(-3)^2 + (-5)^2} = \sqrt{9 + 25} = \sqrt{34} \)

\( AB = \sqrt{34} units \)

Find BC:

BC is easy to determine from the graph directly. The distance from point B to C, is 6 units.

Find AC:

\( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \)

Where,

A(3, 5) => (x1, y1)

C(6, 0) => (x2, y2)

\( AC = \sqrt{(6 - 3)^2 + (0 - 5)^2} \)

\( AB = \sqrt{(3)^2 + (-5)^2} = \sqrt{9 + 25} = \sqrt{34} \)

The length or radius of the windshield wiper to the nearest inch is 10 inches.

For a circle of radius R, the perimeter is:

P = 2*pi*R

such that pi = 3.14

If we have a section of that circle defined by an angle θ, the length of the arc is:

A = (θ/360°)*P =  (θ/360°)* 2*pi*R

In this case, we have a circle whose radius is defined by the length of the windshield wiper.

We also know that in one 90° revolution (so it travels the length of the arc of 90° two times) the tip travels a distance of 31 in.

Then:

A = 2*[(90°/360°)*2*3.14*R] = 31 inches

We need to solve this for R.

R = 31/( 2*(90°/360°)*2*3.14) = 9.8 inches
