The higher F value means higher between-group variability relative to within-group variability. Option(b) is correct.

Analysis of variance (ANOVA) is a statistical formula used to compare variances between means (or averages) of different groups. It is used in a variety of scenarios to determine whether there is any difference in the means of different groups.

The F-value is the ratio of between-group and within-group variation. A high F-value indicates that the between-group variation is greater than the within-group variation. This can be interpreted as a statistically significant difference in the means of your groups.

A large f value (one greater than the F critical value found in a table) indicates that something is significant, whereas a small p-value indicates that all of your results are significant.

Therefore a higher F value the higher between-group variability relative to within-group variability.

The slope of a line that passes through the points (1,−2) and (2,2) is 4.

The two given points are (1,-2) and (2,2).

We have to find out the slope of the line that passes through the two given points.

We know that the slope of a line passing through two points ([tex]x_{1} ,y_{1}[/tex]) and ([tex]x_{2} ,y_{2}[/tex]) is -

[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Using this formula for the given points (1,-2) and (2,2), we can find out the slope of the line passing through them as -

[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }\\= > m = \frac{2-(-2)}{2-1}\\ = > m = \frac{4}{1}\\ = > m = 4[/tex]

Step-by-step explanation:

Substitute g(x) for x-5 in the equation,

x-5 = -5

collect like terms or add 5 to both sides

x = -5+5

x = 0

Solving a system of equations we will see that the song was used on 5 movies and 7 commercials

The variables we will use are:

We know that:

x = y + 2

and:

x*$30 + y*$110 = $760

So the system of equations is:

x = y + 2

x*$30 + y*$110 = $760

Replacing the first equation in the second one:

(y + 2)*$30 + y*$110 = $760

$60 + y*$30 + y*$110 = $760

y*$140 = $760 - $60

y*$140 = $700

y = $700/$140 = 5

The average rate of flow of gasoline into the gas tank is 2.2 gallons per minute.

The average is the mean value of the data set values.

The mean is computed by dividing the total value by the number of items.

For the average rate of flow, divide the total gallons of gasoline filled by the driver, 8.8 gallons, by the number of minutes used in filling the tank.

In this case, the average rate of flow shows the speed that the driver used to fill the car with gasoline.

Starting time = 3:40 P.M.

Ending time = 3:44 P.M.

The difference in filling time = 4 minutes (3:44 - 3:40)

Total number of gallons of gasoline filled = 8.8 gallons

Average rate of flow of the gasoline = 2.2 gallons per minute (8.8/4)

Thus, at an average rate of 2.2 gallons per minute, the driver was able to fill his gas tank in 4 minutes.

Using the factorization of polynomial, the factor of the given expression is (3x-4)(x+2).

In the given question we have to find the each polynomial expression of 3x^2+2x-8.

The given expression is 3x^2+2x-8.

Now finding the factor of the given expression.

The multiply of the first and third variable is 24. The middle term is 2.

So the possible factor is 6 and 4.

3x^2+2x-8 = 3x^2+(6-4)x-8

3x^2+2x-8 = 3x^2+6x-4x-8

3x^2+2x-8 = 3x(x+2)-4(x+2)

3x^2+2x-8 = (3x-4)(x+2)

1. The annual costs from the pothole damage is $156428.

2. The annual costs due to damage from

collisions is $72000 per year.

3. The project should be undertaken

1. The budget is given as $100,000

The number of cars hit potholes per week = 15

Number of cars hit potholes per year = 15*52.148

= 782.14 cars

Total amount of damage per year will be:

= 782.14 * 200 = $156428

2. Number of collusion at intersection per month = 1

Number of collusion at intersection per year = 1 * 12 = 12

Total cost of collusion at intersection per year = 12*6000

= $72000 per year

3. Saving on potholes = 156248 / 100000 = $ 1.56

Saving on collusion at intersection:

= 72000 / 100000

= $0.72

The slope of the function for pronghorn antelope is 60.78 which infers that the rate of speed of the pronghorn is 60.78 miles per hour.

7) The given function that represents the speed of the pronghorn is

y = 60.78x - 5.4

Comparing this function with the general equation of a straight line

y = mx + c we can conclude that the slope of the function is 60.78 .

So the Pronghorn's rate of speed is 60.78 miles per hour.

8) Now the speed of the cheetah is given in the form of a table.

Let us take any two points on the graph

(0.5,21.85) and (2,118.60)

Slope of the line passing through these two points

= (118.6-21.85)/(2-0.5)

=64.5

So the slope of the graph is 64.5 and the average rate of speed of the Cheetah is 64.5 miles per hour.

9) From the above two slopes and the rate of speed we can conclude that the speed of the cheetah is 64.5 mph which is greater than that of the pronghorn 's speed of 60.78 miles per hour.

Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true.

An event's probability is a number between 0 and 1. In this case, 0 denotes the impossibility of the event and 1 represents certainty.

The probability of getting a head in a coin is 1/2.

Therefore, the probability of getting three heads on there flips will be:

The daily production level that will minimize the costs is 106300 units.

Given,

In the question:

The accountant for the factory says that the costs for producing x thousands of units a day can be approximated by the formula

C = 0.04x² -8.504x + 25302.

To find the daily production level that will minimize the costs.

Now, According to the question:

From the information, the function is given as

C = 0.04x² - 8.504x + 25302.

C = cost

From the function, the following can be deduced:

a = 0.04

b = 8.504

c = 25302

Then, -b/(2a) will be:

= -8.504 / (2 × 0.04)

= 106.300

Note that production level will minimize the cost in thousands.

The production level will now be:

= 106.300 × 1000

= 106300 units

Hence, The daily production level that will minimize the costs is 106300 units.
