I'm A Bit Confused On This Math Problem Could Someone Help Me Please? Thanks If You Do! :D

Answers

Answer 1

Answer:

Step-by-step explanation:

Alright so let me try and explain this as best as I can:

So the graph isn't linear because the graph shows a parabola (a boomerang kind of shape that happens if you use an exponent somewhere in a y=mx+b formula if I remember correctly) and not a straight line. Linear graphs cannot curve, and this one does. Not sure why it it would be a function though. Assuming the answer chosen is correct, my best guess as to why it might be a function is because it continues to go in the same direction forever, there is a predictable amount of change between each point and you can follow a formula to find every point on the graph.

I really hope this helps a little!

The area of a circle is 64π cm2, and the area of a sector of the circle is 32π cm2. What is the degree measure of that sector? (Just type the number of degrees. )

Answers

The degree measure of the sector is θ = 180°

We know that the area of a sector is nothing but the area inside the section of the circle created by two radii and an arc.

The formula for the area of a sector of the circle is:

area of a sector = [tex]\frac{\theta}{360} \times \pi \times r^2[/tex]

where θ is the central angle measure in degrees

And πr² is the area of the circle

Here, the area of a sector of the circle A = 32π cm²

and the area of a circle (πr²) =  64π cm²

Using above formula of the area of a sector of the circle,

[tex]A=\frac{\theta}{360} \times \pi \times r^2\\\\32\pi=\frac{\theta}{360} \times \pi \times r^2\\\\32\pi=\frac{\theta}{360} \times 64\times \pi\\\\\theta=\frac{360}{2}\\\\ \theta=180^{\circ}[/tex]

Therefore, the central angle associated to that sector is 180°

Write two expressions that could be used to determine what 340 increased by 19% is​

Answers

The new value = 340 + (19% × 340)

The actual change = The new value - 340

"Information available from the question"

340 increased by 19%

To write in mathematically:

The value of the percentage increase = 19% × 340

The new value = 340 + The value of the percentage increase

The new value = 340 + The value of the percentage increase

= 340 + (19% × 340)

= 340 + 19% × 340

= (1 + 19%) × 340

= (100% + 19%) × 340

= 119% × 340

= 119 ÷ 100 × 340

= 119 × 340 ÷ 100

= 40,460 ÷ 100

= 404.6

The actual change = The new value - 340

                              = 404.6 - 340

a bag contains 8 red marbles, 8 white marbles, and 10 blue marbles. you draw 5 marbles out at random, without replacement. what is the probability that all the marbles are red?

Answers

The probability of all 5 marbles being red is (8/26) x (7/25) x (6/24) x (5/23) x (4/22) = 0.000766.

This can also be written as P(RRRRR) = 8/26 x 7/25 x 6/24 x 5/23 x 4/22. This probability is very small, as the chances of randomly selecting only red marbles from the bag is low.

This calculation is based on the formula for combinations, which states that the probability of selecting r items from a group of n items is nCr x Pr, where nCr is the number of combinations of selecting r items from n items and Pr is the probability of selecting a specific item. In this case, n = 26 and r = 5, so the number of combinations of selecting 5 items from 26 items is 26C5. This is equal to 8x7x6x5x4/5x4x3x2x1, or 8x7x6x5x4/120. The probability of selecting a specific item is 1/26, as there are 26 items in the bag. Therefore, P(RRRRR) = 8/26 x 7/25 x 6/24 x 5/23 x 4/22.

a radio tower is located 275 feet from a building. from a window in the building, a person determines that the angle of elevation to the top of the tower is and that the angle of depression to the bottom of the tower is . how tall is the tower?

Answers

The height of the tower is equal to the length of the side opposite the angle of elevation plus the length of the side opposite the angle of depression.

The angle of elevation and angle of depression in this problem can be used to solve for the height of the tower.

Since the angle of elevation is the angle from the window to the top of the tower and the angle of depression is the angle from the window to the bottom of the tower, the height of the tower can be determined by finding the length of the side opposite the angle of elevation and adding it to the length of the side opposite the angle of depression.

Using trigonometry, we can solve for the two lengths using the sine and cosine functions. The sine of the angle of elevation is equal to the length of the side opposite the angle divided by the hypotenuse. The hypotenuse is the distance from the window to the tower, which is known to be 275 feet. Therefore, we can solve for the side opposite the angle of elevation by multiplying the sine of the angle of elevation by 275. The cosine of the angle of depression is equal to the length of the side opposite the angle divided by the hypotenuse. We can solve for the side opposite the angle of depression in the same way.

Once the two lengths are calculated, we can add them together to find the height of the tower.The height of the tower is equal to the length of the side opposite the angle of elevation plus the length of the side opposite the angle of depression.

Answers

By using the equation of the line of best fit, the​ number of minutes Nikki would need to listen to the radio is equal to 63.275 minutes.

How to determine the​ number of minutes Nikki would need to listen to the radio?

In order to determine the​ number of minutes Nikki would need to listen to the radio, we would have to substitute the value representing the number of commercials (y) into the linear equation and then evaluate as follows;

y = 0.338x − 1.387

When the value of y = 20 commercials, the number of minutes (x) in feet is given by;

20 = 0.338x − 1.387

By rearranging and collecting like terms, we have the following:

0.338x = 20 + 1.387

0.338x = 21.387

Number of minutes (x) = 21.387/0.338

Answers

On average, a player can expect to lose $0.50 for every ticket they play in the Daily 3 lottery. Therefore, the Daily 3 lottery game is not a good investment, as the expected value is negative, and players are likely to lose money in the long run.

How to find the expected value?

To find the expected value of the Daily 3 lottery game, we need to calculate the probability of winning and the expected payout for winning.

The probability of winning the Daily 3 game with a single ticket is 1/1000, since there are 1000 possible 3-digit number combinations and only one of them is the winning combination.

The expected payout for winning is $500, since this is the prize for matching the winning digits in the correct order.

To calculate the expected value, we can use the formula:

Expected Value = (Probability of Winning) x (Payout for Winning) - (Cost of Playing)

Plugging in the values we found, we get:

Expected Value = (1/1000) x ($500) - ($1)

= $0.50 - $1

= -$0.50

This means that, on average, a player can expect to lose $0.50 for every ticket they play in the Daily 3 lottery. Therefore, the Daily 3 lottery game is not a good investment, as the expected value is negative, and players are likely to lose money in the long run.

What is the Pythagorean theorem?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. The theorem can be used to determine how steep mountains or slopes are. To calculate the distance between an observer and a location on the ground when the observer is looking down from a tower or structure. It is mostly utilized in the construction industry.

Given, Jill and Jessica are bike riding at the park. Jill rides her bike around the two edges of the rectangular park while Jessica takes the shortcut

Given the length of the Rectangular park = 100m

The width of the park =  60m

Thus jill ride total = 60 + 100

Jill ride total = 160m

Jessica took a shortcut since she rides diagonally.

From the Pythagorean theorem:

hypotaneus² = base² + height²

Thus,

total distance Jessica covers = √(60² + 100²)

total distance Jessica covers = √3600 + 10000

total distance Jessica covers = √13600

total distance Jessica covers = 116.61

Difference between their distances = 160 - 116.61

The vector equation for the line of intersection of the planes x+4y-4z=-3 and x + z = 5 is r = <5, -2, 0> + t <-1, 5/4, 1>

The equations of the planes are:

x + 4y - 4z = -3                    ..............(1)

and x + z = 5                      .............(2)

Subtract equation (2) from equation (1),

( x + 4y - 4z + 3) - (x + z - 5 ) = 0

4y - 5z + 8 = 0

we can rewrite is as,

4y = 5z - 8

y = 5/4 z - 8/4

y = 5/4 z - 2                  ...............(3)

Here, we don't have enough equations to uniquely solve for either y or z. So, we set z = t, where t can be any real number.

The variable t is the free parameter for the parametrization of the line.

Substitute z = t in equation (3) we get,

y = 5/4 t - 2        

From equation (2),

x = 5 - z

For z = t,

x = 5 - t

Thus, the parametrization of the line would be,

Lucia and Danna both recently purchased fitness watches. The watches count the number of steps they walk in a day. At lunchtime, Lucia has 5445 steps and Danna has 4995 steps. Lucia averages 800 steps per hour and Danna averages 900 steps per hour.

A. Write and solve a system of linear equations that represent the total number of steps each person takes.
B. Interpret the meaning of the solution in terms of the problem situation.

Answers

The system of linear equations is y = 800x + 5445, and y = 900x + 4995. The solution is 4.50. This states that the number of steps taken by Danna and Lucia will be equal after 4.50 hours.

What is system of linear equation?

The set of two or more linear equations containing the same variables is known as a system of linear equations in mathematics. In this case, linear equations are first-order equations, where the maximum power of the variable is 1. One, two, or three variables may be present in a linear equation.

Let us suppose the number of hours = x.

Let us suppose the total number of steps = y.

Given that, Lucia has 5445 steps and Lucia averages 800 steps per hour.

For Lucia the linear equation is:

y = 800x + 5445

For Danna, Danna has 4995 steps and Danna averages 900 steps per hour.

For Danna the linear equation is:

y = 900x + 4995

The system of linear equations is:

y = 800x + 5445 (equation 1)

y = 900x + 4995 (equation 2)

Substitute the value of y of equation 1 in equation 2:

800x + 5445 = 900x + 4995

5445 - 4995 = 900x - 800x

450 = 100x

x= 4.50

B. The solution of the linear equation is 4.50. This states that the number of steps taken by Danna and Lucia will be equal after 4.50 hours.

A local news story claims that 53% of high school

males agree with the statement "I am ok with a girl

playing on the football team because there is not a

football team for girls. " To investigate this claim, an SRS

of 100 males from a large local high school is selected.

In the sample, 38 males agreed with the statement. We

used technology to simulate choosing 240 SRSs of size

n = 100 from a population of males where 53% agreed

with the statement. The dotplot shows p = the sample

proportion of males who agree with the statement for

each of the 240 samples.

Find the mean and standard deivation of the sampling

distribution.

Answers

The mean  is 24 and standard deviation is 10 of the sampling distribution.

The term in math called standard deviation is defined as the standard deviation of the sampling distribution is also known as the standard error and it is inversely proportional to the sample size in which is as the sample size increases the standard deviation of the sample means decreases.

Here we know that the value of n is 100 and the number of samples 240.

Agreed count = 38.

Here we have to assuming the expected population standard deviation to be 10, and a population size of 100, the study would require a sample size of 24 to estimate a mean with 53% confidence and a precision of 1.5.

Then the standard deviation is 10.

In right triangle ABC, ZC is a right angle, m ZA = 52, AC = 10. 01, and AB = c.

sin 52° 0. 788

cos 52° 0. 616

tan 52° 1. 280

What is the measurement of AB?

If necessary, round your answer to two decimal places, like this: 42. 53

Answers

The length of side AB rounded to two decimal places is 16.25.

In a right angle triangle, the side on the base of the angle in question is divided by the hypotenuse. In this case, we can use the cosine ratio to find the length of AB.

We are provided with the following information,

C is the right angle, C= 90°

A= 52°

AC = 10. 01

sin 52° = 0. 788

cos 52° = 0. 616

tan 52° = 1. 280

Now,

since angle C is the right angle, AB is the hypotenuse.

Therefore, with respect to Angle A, AC will be the base and BC will be the perpendicular.

We know, cos x= base/hypotenuse

In this case, cos A = AC / AB

cos 52° = 10. 01/ AB

AB = 10. 01 / 0. 616

AB = 16.25

If you invest $10,000 in a bank which one is a better investment? A) 9% compounded monthly b) 9. 3% compounded annually

Answers

If you invest $10000 in a bank , then the better investment plan is (a) 9% compounded monthly .

The amount to be invested in bank is = $10000  ;

the formula to calculate the final amount by compounding is given as :

A = P(1 + r/n)^(nt)   ;

Where: (A) = final amount , (P) = initial amount ,

⇒ r is interest rate (in decimal form) , n is number of times the interest is compounded per year and

⇒ t is number of years investment is made

(a) the rate of interest is 9% compounded monthly ;

in this case n = 12  , because there are 12 months in 1 year ;

So , Amount = 10000(1 + 0.09/12)^(12×t)

Amount = 10000 × (1.0075)^(12×t)  

Suppose t = 1 ;

we get , Amount = 10000 × (1.0075)¹² ≈  10938 .

(b) the rate of interest is 9% compounded annually ;

in this case n = 1  , because compounded annually ;

So , Amount = 10000 × (1 + 0.09)^(1×t)

Amount = 10000 × (1.09)^t  

Suppose t = 1 ; we get , Amount = 10000 × (1.09)¹ ≈ 10900 ;

On comparing both the interest value we observe that ,

the monthly compounding returns more value than compounding annually  .

Joshua goes to a store an buys an item that costs x dollars. He has a coupon for 5% off, and then a 6% tax is added to the discounted price. Write an expression in terms of x that represents the total amount that Joshua paid at the register

Answers

The expression representing the total amount paid by Joshua at the register is 1.007x dollars.

We have,

To represent the total amount that Joshua paid at the register, we need to account for the following steps:

- Applying the 5% discount to the original price x:

Discount = 5% of x = 0.05x

Calculating the price after the discount:

Price after discount = x - Discount = x - 0.05x = 0.95 x

Adding the 6% tax to the discounted price:

Tax = 6% of the discounted price = 0.06 x (0.95x)

The expression for the total amount that Joshua paid at the register:

Total amount paid

= Price after discount + Tax

= 0.95 x + 0.06 (0.95 * x)

Simplifying the expression:

Total amount paid = 0.95x + 0.057x

Total amount paid = 1.007x

Thus,

The expression representing the total amount paid by Joshua at the register is 1.007x dollars.
