Now your friend would also like to determine the most likely continent of origin for each coin. Logistic regression model best suited to predict the continent of origin. So the option b is correct.

A variable's value can be estimated using linear regression analysis depending on the value of another variable. The dependent variable is the one you want to be able to forecast. The independent variable is the one you're using to make a prediction about the value of the other variable.

Based on a given dataset of independent variables, logistic regression calculates the likelihood that an event will occur, such as voting or not voting. Given that the result is a probability, the dependent variable's range is 0 to 1.

The log chances of the outcomes are modelled as a linear combination of the predictor variables in multinomial logistic regression, which is used to model nominal outcome variables.

Use the formula for circles.

[tex]x^{2} + y^{2} = r^{2}[/tex]

Since we already have the values of x and y in the given problem (-2,3), substitute the values in the fomula.

[tex]x^{2} + y^{2} = r^{2}[/tex]

[tex](-2)^{2} + (3)^{2} = r^{2}[/tex]

[tex]4 + 9 = r^{2}[/tex]

[tex]13 = r^{2}[/tex] (square both sides to get the radius)

[tex]\sqrt{13} = \sqrt{r^{2} }[/tex]

Answer:

5/8 is greater than 5/7. 5/8 is 0.625, while 5/7 is 0.714.

Step-by-step explanation:

5/8 is greater than 5/7. 5/8 is 0.625, while 5/7 is 0.714.

Answer:

5/7

A fraction is a fragment of a whole number, used to define parts of a whole.  The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.

If we think about 5/7, we can relate this to a circle split into 7 parts, with 5 shaded in.

You can do the same for 5/8. Think of a circle with 8 parts, and 5 shaded in.

A way to figure out which is bigger is to find a common denominator between the two.

A common denominator is two fractions with the same denominator (Hence the name). Solving for a common denominator can be done with cross multiplication.

5/7 = 40/56

5/8 = 35/56

We can visibly see, that 40/56 (5/7) is bigger, therefore making 5/7 the greater fraction.

Answer:

the teacher does not have enough paint and he needs 1351.5-1324.8 = 26.7 square cm more paint.

Step-by-step explanation:

The canvas each student has is 5.3 cm wide and 8.5 cm tall. The area of the canvas is (5.3 cm)(8.5 cm) = 45.05 square cm.

The art teacher has 6 bottles of paint, each bottle covers 220.8 square cm of canvas. So he has 6220.8 = 1324.8 square cm of paint.

There are 30 students in the class and each student has a canvas of 45.05 square cm. So in total the students have 30*45.05 = 1351.5 square cm of canvas.

The teacher has 1324.8 square cm of paint and the students have 1351.5 square cm of canvas.

Therefore the teacher does not have enough paint and he needs 1351.5-1324.8 = 26.7 square cm more paint.

The probability of selecting a red or a blue tile from one of the bags is 1. This can be calculated by adding the probability of selecting a red tile (6/10) and the probability of selecting a blue tile (4/10) together. The equation for this is P(Red or Blue) = P(Red) + P(Blue), which simplifies to 10/10, or 1.

The probability of selecting either a red or blue tile from one of the bags can be calculated using the following equation:

P(Red or Blue) = P(Red) + P(Blue)

where P(Red) is the probability of selecting a red tile and P(Blue) is the probability of selecting a blue tile.

In this case, P(Red) = 4/10 and P(Blue) = 6/10. Therefore, the probability of selecting either a red or blue tile from one of the bags is:

probability of selecting

P(Red or Blue) = 4/10 + 6/10

P(Red or Blue) = 10/10

P(Red or Blue) = 1

This means that there is a 100% chance of selecting either a red or blue tile from one of the bags.

Therefore , the solution of the given problem of speed comes out to be

he needs to drive at 77.77 mph.

How quickly something is traveling is determined by its speed from a distance. How far an object moves in a certain length of time depends on its speed. Speed is calculated as follows: velocity = range x time. The most used units for expressing speed are meters per second (m/s), kilometers per hour (km/h), and kilometers per second (mph) (mph).

Here,

70 + 50 = 120 miles is indeed the total distance.

You would need 2.4 hours to travel the 120 miles at such an approximate speed of 50 mph.

However, you are already on the road for 1.5 hours, so you must finish the trip in 0.9 hours.

You need to travel at a speed of 77.77 mph to complete the final 70 miles approximately 0.9 hours.

Here we have given that  it be for more than 4 elk in the sample to survive to adulthood.

Then the probability is calculated by using the binomial probability,

And here we have to use the addition rule for mutually exclusive event, then we get,

=> P(AUB) = P(A or B) = P(A) + P(B)

At the possibility of k = 5 we have the binomial probability to be evaluated as follows:

=> P(X = 5) = 21 (0.44)⁵ (0.56)² ≈ 0.1086

At the possibility k = 6 then the binomial probability to be calculated as,

=> P(X = 6) = 7(0.44)⁶ (0.56)¹ ≈ 0.0284

Finally at the value of k = 7 then the binomial probability to be evaluated as,

=> P(X = 7) = 1 (0.44)⁷(0.56)° ≈ 0.0032

Therefore the two different numbers of successes are impossible on same simulation is by applying the addition rule for mutually exclusive events is calculated as,

=> P(X > 4) = P(X = 5) + P(X = 6) + P(X = 7)

For a set of 16 positive integers to have a mean, median, and mode all equal to 16, the numbers in the set must all be equal to 16. Therefore, the largest possible value of one of the numbers in the set is 16.

The mean, median and mode of a set of numbers are all measures of the "typical" or "central" value of the set.

The mean is the sum of all the numbers divided by the number of elements in the set, the median is the middle value when a set of numbers is arranged in order of magnitude, and the mode is the number that appears most frequently in the set.

In this case, if all the 16 integers in the set are equal to 16, then the mean, median, and mode will all be 16 as well. Since the question states that the median, mode, and mean are all equal to 16, the only way for this to be true is if all the 16 integers in the set are equal to 16. So the largest possible value of one of the numbers in the set would be 16.

a. The length and width of the smaller wall are 14 feet and 8 feet, respectively.

b. The area of the smaller wall is 14 feet x 8 feet = 112 square feet.

c. The area of the larger wall is 20 feet x 8 feet = 160 square feet.

d. The total area of the four walls in the room is 112 square feet + 112 square feet + 160 square feet + 160 square feet = 544 square feet.

e. To find the cost of painting the room walls with two coats of paint, we need to know the total area of the walls, and the cost of one gallon of paint. We can use the information provided: a gallon of paint covers 350 square feet on average and the cost of one gallon of paint is $36.50.

We can divide the total area of the walls by the coverage of one gallon of paint, then multiply that by the cost of one gallon of paint.

544 square feet / 350 square feet/gallon * $36.50/gallon = $38.34

So the cost of painting the room walls with two coats of paint is $38.34.

The equations of the two circles are (x-0)^2 + (y-0)^2 = 2^2 or x^2 + y^2 = 4 and (x-1)^2 + (y-1)^2 = 1^2 or (x-1)^2 + (y-1)^2 = 1.

The equation of a circle with centre (a,b) and radius r is given by (x-a)^2 + (y-b)^2 = r^2.

C1 has centre (0,0) and radius 2, so its equation is (x-0)^2 + (y-0)^2 = 2^2 or x^2 + y^2 = 4.

C2 touches the x and y axes each in one point, so it must have a centre on the line y=x and a radius equal to the distance from the centre to either of those points of tangency. Since the centre of C2 is on the line y=x and it is in the first quadrant, the coordinates of the centre are (1,1). The distance from the centre to the point of tangency on the x-axis is 1, so the radius is 1. The equation of C2 is (x-1)^2 + (y-1)^2 = 1^2 or (x-1)^2 + (y-1)^2 = 1.

Therefore, The equations of the two circles are (x-0)^2 + (y-0)^2 = 2^2 or x^2 + y^2 = 4 and (x-1)^2 + (y-1)^2 = 1^2 or (x-1)^2 + (y-1)^2 = 1.

If the graph only touches the x-axis at the x-intercept, then it is said to "touch" the x-axis. This indicates that the graph does not pass through the x-axis at the x-intercept, but rather just touches it.

The x-intercept of a graph is the point at which the graph crosses the x-axis. It is also known as the abscissa. The x-coordinate of the x-intercept is the value where the graph intersects the x-axis.

The x-intercept of a graph is the point at which the graph crosses (or, in some cases, touches) the x-axis. A graph can have one or more x-intercepts. If the graph only crosses the x-axis once, then it has only one x-intercept. If the graph crosses the x-axis twice or more, then it has multiple x-intercepts. In either case, the x-intercepts can be described as either "crosses" or "touches" the x-axis.
