A decagon has 10 sides. One angle of a regular decagon measures (8w + 17)°. Determine the value of w. Round to the nearest whole number. w = 144 w = 23 w = 16 w = 8

Answers

Answer:

I think the answer is 144

The value of w to the nearest whole number is 16°

What a regular polygon?

If a polygon has equal sides and angles, it is said to be regular. As a result, an equilateral triangle is a regular triangle, and a square is a regular quadrilateral.

Given:

Decagon has 10 sides.

As, sum of interior angles of a polygon = ( n - 2) x 180

where n = number of sides of polygon

Here n = 10

sum of interior angle = ( 10 - 2) x 180 which is 1440°

If a regular polygon has equal angles and each angle is (8w + 17)

10( 8w + 17) = 1440

8w + 17 = 144

8w = 144 - 17

8w = 127

w = 127/8

w = 15.875

Thus, the value of w = 16°

Step-by-step explanation:

Let the number of small boxes is s and number of large boxes is l.

s and l are our variables.

Total number of boxes is 21:

s + l = 21

This is your first equation.

The volume of a small box is a (since it is not given, if you have it please replace it with that number), and the volume of all small boxes is as.

The volume of a larger box is 14 cubic feet, and the volume of all large boxes is 14l cubic feet.

Total volume is 252 cubic feet, add the two volumes together:

as + 14l = 252

And this is your second equation (don't forget to replace a with the volume of a small box).

Answer:

m∠C = 50 degrees

Step-by-step explanation:

∠CAQ is a straight angle (180) so ∠CAB is supplementary to ∠QAB

∠CAQ = ∠QAB + ∠CAB

180 = 110 + ∠CAB

180 - 110 = ∠CAB

70 = ∠CAB

The total angle measurement in all triangles is 180 degrees, knowing this, we can set up the equation:

180 = ∠CBA + ∠BCA + ∠CAB

180 = 2 + 29x + 24x + 2 + 70

180 = 74 + 53x

180 - 74 = 53x

106 = 53x

2 = x

Knowing x = 2, we can solve for m∠C

24(2) + 2 = ∠C

48 + 2 = ∠C

50 = ∠C

Assuming the assumptions of Analysis of Variance are satisfied, a higher F value means... (select all that apply)

a.
...a greater chance of rejecting the null hypothesis.

b.
...higher between-group variability relative to within-group variability.

c.
...a higher p value.

Answers

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.

Find the area of the shaded region in the figure below, if the diameter of the circle is 12 and the height of the rectangle is 11. Use 3.14 for pi and round to the nearest hundredth.

Answers

The area of the shaded region is 75.48 rounded to the nearest hundredth, considering the areas of the circle and rectangle

How to calculate for the area of the shaded region

We have to first calculate for the area of the rectangle, and then calculate for the area of half the circle and then subtract it from the area of the rectangle to get the area of the shaded region.

Area of rectangle = Length × breadth

Area of rectangle = 12 × 11(diameter of the circle is also the length of the rectangle)

Area of rectangle = 132.

Area of circle = πr²

Area of the circle = 3.14 × 6² (6 is the radius given that the diameter = 12)

Area of the circle = 3.14 × 36

Area of the circle = 113.04

Half the area of the circle = 113.04/2

Half the area of the circle = 56.52

Area of the shaded region = 132 - 56.52

Area of the shaded region = 75.48

Therefore, by calculating for areas of the circle and rectangle, we are able to derive the area of the shaded region to be 75.48

He estimated the market demand and supply function as follows demand :P=q²+13/2q+64 and supply: P= 10q²-45/2q-164​

We need to find the equilibium price

The equilibrium price (EP) is the price where the demand for a product or service balances its supply. .

At equilibium price

Demand function = supply function

q²+13/2q+64 = 10q²-45/2q-164​

(10 - 1)q² - (45/2 + 13/2)q - (164 + 64) = 0

9q² - 29q - 228

q = 6.895 = 6.9

The equilibium price = 6.9² + (13/2)6.9 + 64

= 163.36

similarly putting the value of q in supply function we get supply quantity   ie 149.95 = 150

Therefore, the equilibium price is 163.39 and the supply quantity is 149.95 = 150

Answers

Answer: The equation that represents this situation is y = -15x + 135

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the rate of change and b is the y intercept.

Let y represent the amount of boxes remaining after x days.

She starts with 135 boxes, hence b = 135. She sells at a constant rate of 15 boxes each day, hence m = -15. The equation becomes:

y = -15x + 135

The first point should be plotted at (9,0) then the next at (0,135). Just plot multiples of 15 on the chart until you get to the 9th multiple

Step-by-step explanation:

A city administrator with a $100,000 annual budget is trying to decide between fixing potholes or directing traffic at several busy intersections after school. Studies have shown that 15 cars hit potholes every week, causing average damages of $200. Collisions at the intersections are less frequent, averaging one per month at an average cost of $6,000, although none have ever caused injuries or deaths. Use this information to answer the following questions.

1. What are the annual costs from the pothole damage?

2. What are the annual costs due to damage from
collisions?

3. Given the size of the annual budget, make your
recommendation as to which project should be
undertaken. Explain you answer in terms of dollar
benefits per dollar spent.

Answers

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

How to calculate the value?

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

So from above, it is clear that if the budget is spent on potholes, more savings will be done. Thus the budget should be invested in potholes.

A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.M. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 8.8 gallons. What is the average rate of flow of the gasoline into the gas tank?

Answers

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

What is the average?

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.

Nakeisha will earn $30 every time one of her songs is played in a commercial and she will earn $110 every time one of her songs is played in a movie. Nakeisha's songs were played on 2 more commercials than movies, and her total earnings on the royalties from all commercials and movies was $760. Write a system of equations that could be used to determine the number of commercials and the number of movies on which Nakeisha's songs were played. Define the variables that you use to write the system. Please help this is due tonight!!!

Answers

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

How to determine the numbers of commercials and movies?

The variables we will use are:

x = number of commercial.y = number of movies.

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

Then the value of x is:

x = y + 2 = 5 + 2 = 7

Find the equation of a line that passes through the point (5,3) and has a gradient of 2. Leave your answer in the form y = m x + c

Answers

The equation of the line in slope intercept form is y = 2x - 7..

How to find the equation of a line?

The equation of a line can be represented in slope intercept form as follows;

y = mx + b

where

m = slopeb = y-intercept

Therefore, the equation of the line that passes through  (5,3) and has a gradient of 2 can be found as follows;

m = 2

let's find the y-intercept using (5, 3)

3 = 2(5) + b

b = 3 - 10

b = -7

Therefore, the equation of the line is y = 2x - 7.

A cellphone provider has the business objective of wanting to determine the proportion of subscribers who would upgrade to a new cellphone with improved features if it were made available at a substantially reduced cost. Data are collected from a random sample of 500 subscribers. The results indicate that 110 of the subscribers would upgrade to a new cellphone at a reduced cost. Reducing the price will be profitable if at least 20% of the subscribers would upgrade. Complete parts​ (a) and​ (b) below

b. What is the test​ statistic?

Answers

The test statistic, using the z-distribution, is given as follows:

z = 1.12.

What are the hypothesis tested?

At the null hypothesis, it is tested if there is not enough evidence that the proportion is greater than 20%, that is:

[tex]H_0: p \leq 0.2[/tex]

At the alternative hypothesis, it is tested if there is evidence that the proportion is greater than 20%, that is:

[tex]H_0: p > 0.2[/tex]

What is the test statistic?

The test statistic is given by the equation presented as follows:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which the variables of the equation are listed as follows:

[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.

In the context of this problem, the values of these parameters are given as follows:

[tex]p = 0.2, n = 500, \overline{p} = \frac{110}{500} = 0.22[/tex]

Hence the test statistic is given as follows:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.22 - 0.2}{\sqrt{\frac{0.2(0.8)}{500}}}[/tex]

z = 1.12.

Pleaseeee help me. I'm stuck on a math question.

Answers

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.

You flip three coins eight times. Are you guaranteed to get three heads at least once

Answers

When one flip three coins eight times, there no guarantee to get three heads at least once as the probability is low.

What is probability?

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:

= P(head)³

= 1/2 × 1/2 × 1/2

= 1/8

Therefore, the probability is low and the heads aren't guaranteed.
