Question C Please!!!!!

Answers

Answer 1

The explanatory variable is; A. square footage.

The correct scatter diagram of the data is: B. scatter diagram.

The linear correlation coefficient between square footage and asking price is 0.91.

How to determine the linear regression equation and correlation coefficient?

In this scenario, the square footage (x) would be plotted on the x-axis of the scatter plot while the selling price (y) would be plotted on the x-axis of the scatter plot.

By critically observing the scatter plot (see attachment) which models the relationship between the square footage (x) and the selling price (y), an equation for the linear regression is given by:

y = 13.762782 + 0.156710276x

Correlation coefficient, r = 0.904601208 ≈ 0.91.

In conclusion, there is a strong correlation between the data because the correlation coefficient (r) approximately equals to 1;

0.7<|r| ≤ 1   (strong correlation)

Answers

Answer:

A

Step-by-step explanation:

The opposite of an integer is the number on the opposite side of the number line with the same distance from zero. So, the integers that are opposites are 14 and -14, 17 and -17, 32 and -32, and 15 and -15. This is because these pairs have the same absolute value but different signs. For instance, the absolute value of 14 is 14, and the absolute value of -14 is also 14. Therefore, -14 is the opposite of 14. Similarly, -17 is the opposite of 17 and so on.

Mr. Cosgrove, a farmer, needs to build a new feed trough for his goats. The trough will be in the shape of a rectangular prism and hold approximately 20 gallons, or 4,620 cubic inches, of food. The height of the trough will be 6 inches so that the goats can access their food easily. Mr. Cosgrove decides to make the trough 8 times as long as it is wide so all his goats can eat at the same time.

Which equation can you use to find the width of the feed trough?

A.) 4,620w = 8 x w x 6
B.) 4,620 = 8w x w x 6

To the nearest tenth of an inch, how wide will the feed trough be?

___ inches wide

Answers

The correct equation to find that can be used to find the width of the feed  trough is (b) 4620 = 8w×w×6, and the width of the "feed-trough"  is 9.8 inches wide.

The "Volume" of "rectangular-prism" can be found using formula V = l×w×h, where V is = volume, l is = length, w is = width, and h is = height.

We know that the volume of the "feed-trough" is 4,620 cubic inches, and

The height is = 6 inches. Let us denote the width as "w" and the length as "8w" (because trough's length is 8 times the width),

So, the equation for the volume of the feed trough is:

⇒ 4620 = (8w) × (w) × (6),

So, the correct equation to find the width is Option (b) 4620 = (8w) × (w) × (6).

Simplifying further,

We get,

⇒ w² = 96.25,

⇒ w ≈ 9.8 inches (rounded to the nearest tenth)

Therefore, the width of the feed trough will be approximately 9.8 inches.

In the rhombus PQRS, if angle ∠ SPQ = 120° then ∠SPO is 30°

∠POS is 90° and ∠PSO is 60 degrees, ∠PO is 90° and ∠SO  is 150°

PQRS is a rhombus.

∠ SPQ = 120° and SP = 8.

We have to find angles,∠SPO = (180° - ∠SPQ) / 2

= (180° - 120°) / 2

= 30°

∠POS = 90°

Now we have to find angle PSO

∠PSO+∠SPO+∠POS =180

30+90+∠PSO=180

120+∠PSO=180

∠PSO=180-120

∠PSO=60 degrees

∠PO = 360° / 4 = 90°

∠SO = 180° - ∠POS = 180° - 30°

How is y=4(2)^x-3 translated from the graph of y=4(2)^x

Answers

The graph of y=4[tex](2)^{x}[/tex]-3 is the same as the graph of y=4[tex](2)^{x}[/tex] shifted downwards by 3 units.

The function y=4[tex](2)^{x}[/tex] is an exponential function with base 2 and vertical intercept at (0, 4).

To translate this function to the graph of y=4[tex](2)^{x}[/tex]-3, we need to shift the graph downwards by 3 units. This can be achieved by subtracting 3 from the original function as follows:

y = 4[tex](2)^{x}[/tex] - 3

Now, the vertical intercept of the new function y=4[tex](2)^{x}[/tex]-3 is at (0, 1), which is 3 units below the intercept of the original function.

Notice how the entire graph has shifted down by 3 units, while maintaining the same shape as the original exponential function y=4[tex](2)^{x}[/tex].

c) The NY Knicks won 35 games out of 65 games. What is the probability that they win the next game?

d) Find the experimental probability of a player on the New York Liberty being over 73 inches​

Answers

The probability that they win the next game and player on the New York Liberty being over 73 inches​ is 53% and 50%

We are given that;

Games= 35/35

Now,

We can use the past performance of the Knicks as an estimate of their probability of winning a game. They won 35 games out of 65 games, so their probability of winning a game is:

P(win) = 35/65 P(win) = 0.538

To find the experimental probability of a player being over 73 inches, we need to count how many players are over 73 inches and divide by the total number of players. There are six players who are over 73 inches, so the experimental probability is:

P(over 73 inches) = 6/12 P(over 73 inches) = 0.5

Therefore, by probability the answer will be 53% and 50%.

Jasica Parker would like to have ​$83,000 to buy a new car in 7 years. To accumulate $83,000 in 7 ​years, how much should she invest monthly in a sinking fund with 3% interest compounded​ monthly?

Answers

Jasica should invest $878.84 per month in a sinking fund with 3% interest compounded monthly to accumulate $83,000 in 7 years.

How much should Jasica invest monthly in a sinking fund with 3% interest?  

To determine how much Jasica should make in a sinking fund, we can use the formula for the future value of an annuity due:

FV = PMT x [tex](((1 + r/n)^nt[/tex] - 1) / (r/n))

Where:

FV = future value

PMT = monthly payment

r = interest rate (as a decimal)

n = number of compounding periods per year

t = number of years

In this issue, we are solving for PMT.

Given:

FV = $83,000,

r = 0.03 (3% expressed as a decimal),

n = 12 (monthly compounding),

t = 7 years.

Plugging in the values, we have:

$83,000 = PMT x [tex](((1 + 0.03/12)^(12*7)[/tex] - 1) / (0.03/12))

Simplifying:

$83,000 = PMT x (94.4523)

PMT = $83,000 / 94.4523

PMT = $878.84 (rounded to the nearest cent)

Therefore, Jasica should invest $878.84 per month in a sinking fund with 3% interest compounded monthly.

Answers

The probability that it weighs more than 51 pounds exactly 53 pounds.

Given that, mean weight of 50 pounds and a standard deviation of 0.5 pounds.

We need to find the probability that it weighs more than 51 pounds,

P(X = 53) = 0

z = (51 - 50) / 0.5 = 2.00

P(X > 51) = P(z > 2.00) = 0.0228

z1 = (49 - 50) / 0.5 = -2.00

z2 = (51 - 50) / 0.5 = 2.00

P(49 < X < 51) = P(-2.00 < z < 2.00) = P(z < 2.00) - P(z < -2.00) = 0.9772 - 0.0228 = 0.9544

Answers

The approximate shortest distance between the treasure chest and driftwood is 3.2 yards

The correct answer is an option (C)

From the attached figure of the coordinate plane,

the coordinates of the palm tree = (1, 2),

the coordinates of the  treasure chest = (5, 8)

and the coordinates of the driftwood = (8, 7)

We know that the distance formula between two points (x₁, y₁) and (x₂, y₂) is:

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

We need to find the distance between the treasure chest and driftwood.

Let (x₁, y₁) = (5, 8)

and (x₂, y₂) = (8, 7)

Using distance formula, the approximate shortest distance between the treasure chest and driftwood would be,

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(7 - 8 )² + (8 - 5)²]

d = √[(-1)² + (3)²]

d = √[1 + 9]

d = √(10)

d = 3.1622

d ≈ 3.2 yards

This is the required distance between the treasure chest and the driftwood.

Find the complete question below.

Gabriella needs 120 m of fence to surround a rectangular garden. The length of the garden is three times its width, W.

How wide is the fence?

Answers

Answer: The width of the garden/fence will be 15 m.

Step-by-step explanation: First, we have to understand that there will be two wide sides and two long sides, and in a rectangle, the long sides always equal each other and the wide sides equal each other as well. This means that one width and one length will equal 120/2=60.

In other words:

one length of the garden + one width of the garden = 60

Now that we know this, we move on to the "3 times" part of the question. For this step, it is easiest to imagine quarters of something, because 3/4 of something will always be 3 x 1/4 of something; The proportion for 3/4:1/4 will always be 3:1.

60 x 3/4 is equal to 45 and 60 x 1/4 is equal to 15.

To check our answer, L+W+L+W = 45+15+45+15 = 120.

This means each wide side is equal to 15.

b) Instead, they decide to borrow $50 million from a bank with a maturity of 5 years. If the interest rate is 8%, what is the monthly payment? What is the balance at the end of 28 months?

Answers

The bond price at 12% maturity is $435.42, at 10% maturity is $500.00, at 8% maturity is $607.28, and at 6% maturity is $748.65. The balance at the end of 28 months is approximately $41,097,019.67.

To determine the price of the bond at different yield to maturity rates, we need to use the bond pricing formula

Bond price = (Coupon payment / (1 + YTM)¹) + (Coupon payment / (1 + YTM)²) + ... + (Coupon payment + Face value) / (1 + YTM)ⁿ

Where Coupon payment = Annual coupon rate x Face value

YTM = Yield to maturity

n = Number of years to maturity x Number of coupon payments per year

Using $1,000 as the face value and an annual coupon rate of 10%, we have

At 12% yield to maturity

Coupon payment = 0.10 x $1,000 = $100

n = 20 x 2 = 40

Bond price = ($100 / (1 + 0.12)¹) + ($100 / (1 + 0.12)²) + ... + ($100 + $1,000) / (1 + 0.12)⁴⁰

Bond price = $435.42

At 10% yield to maturity

Coupon payment = 0.10 x $1,000 = $100

n = 20 x 2 = 40

Bond price = ($100 / (1 + 0.10)¹) + ($100 / (1 + 0.10)²) + ... + ($100 + $1,000) / (1 + 0.10)⁴⁰

Bond price = $500.00

At 8% yield to maturity

Coupon payment = 0.10 x $1,000 = $100

n = 20 x 2 = 40

Bond price = ($100 / (1 + 0.08)¹) + ($100 / (1 + 0.08)²) + ... + ($100 + $1,000) / (1 + 0.08)⁴⁰

Bond price = $607.28

At 6% yield to maturity

Coupon payment = 0.10 x $1,000 = $100

n = 20 x 2 = 40

Bond price = ($100 / (1 + 0.06)¹) + ($100 / (1 + 0.06)²) + ... + ($100 + $1,000) / (1 + 0.06)⁴⁰

Bond price = $748.65

To calculate the monthly payment and balance of the loan from the bank, we can use the formula for the monthly payment of an amortizing loan

P = (r × A) / (1 - (1 + r)⁻ⁿ)

where P is the monthly payment, r is the monthly interest rate (which is the annual interest rate divided by 12), A is the loan amount, and n is the total number of months in the loan.

First, we need to calculate the values of r, A, and n

r = 0.08 / 12 = 0.00667 (monthly interest rate)

A = $50,000,000 (loan amount)

n = 5 years × 12 months/year = 60 months (total number of months in the loan)

Now, we can plug these values into the formula to calculate the monthly payment

P = (0.00667 × $50,000,000) / (1 - (1 + 0.00667)⁻⁶⁰)

P ≈ $1,029,299.29

Therefore, the monthly payment on the loan is approximately $1,029,299.29.

To find the balance at the end of 28 months, we can use the formula for the remaining balance of an amortizing loan

B = (P * (1 - (1 + r)⁻ⁿ')) / r

where B is the remaining balance, r is the monthly interest rate, P is the monthly payment, and n' is the number of months remaining in the loan (which is equal to the total number of months minus the number of months already paid).

After 28 months, the number of months remaining in the loan is

n' = 60 - 28 = 32

We can now plug the values of P, r, and n' into the formula to find the balance

B = ($1,029,299.29 × (1 - (1 + 0.00667)⁻³²)) / 0.00667

B ≈ $41,097,019.67

Therefore, the balance at the end of 28 months is approximately $41,097,019.67.

Please help me with part (b) and (c) pleaseeee
thank youuu

Answers

The answers are explained in the solution.

Given are lines drawn in a coordinate plane, we need to identify the equations,

So, we have,

y = 2x – 4 = r

y = 2x + 4 = p

This is because these lines are parallel and have same slope, also the y-intercept is -4 and 4,

y = x = n

y = -x = s

This is also because, the line of y = x passes from origin.

b) We can use a translation to map the line p or r onto the line r or p.

c) We can use an axial symmetry in the y-axis to map the line n or s onto the line s or n.

d) The line s or n is mapped onto itself under central symmetry in the point (0, 0).

What is the Fundamental Counting Theorem?

The Fundamental Counting Theorem states that if there are m ways to do one thing and n ways to do another, then there are m x n ways to do both.

This can be extended to more than two events, where the number of ways to do all the events is the product of the number of ways to do each individual event, according to the equation presented as follows:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

The codes are composed as follows:

Two letters -> each with 22 options, as letters can be repeated.Three digits -> each with 8 options, as digits can also be repeated.

Thus the total number of codes is obtained as follows:

N = 22² x 8³

N = 247,808 coupon codes.

Read this passage from My Antonia.I can remember a score of these country girls who were in service in Black Hawk during the few years I lived there, and I can remember something unusual and engaging about each of them. Physically they were almost a race apart, and out-of-door work had given them a vigour which, when they got over their first shyness on coming to town, developed into a positive carriage and freedom of movement, and made them conspicuous among Black Hawk women.That was before the day of high-school athletics. Girls who had to walk more than half a mile to school were pitied. There was not a tennis-court in the town; physical exercise was thought rather inelegant for the daughters of well-to-do families. Some of the high-school girls were jolly and pretty, but they stayed indoors in winter because of the cold, and in summer because of the heat. When one danced with them, their bodies never moved inside their clothes; their muscles seemed to ask but one thingnot to be disturbed. I remember those girls merely as faces in the schoolroom, gay and rosy, or listless and dull, cut off below the shoulders, like cherubs, by the ink-smeared tops of the high desks that were surely put there to make us round-shouldered and hollow-chested.Which theme is best supported by the comparison in this passage? "Although there has long been terrorism in varied contexts, contemporary terrorism poses a new and ominous problem. . . . We have long considered how to protect citizens against invading armies, and this might be the arena that is most nearly analogous to protection against terrorists. But foreign terrorists are not so transparent as invading armies, and the issue of protecting ourselves against them necessarily involves judgments on how to distinguish them from peaceful citizens and alien residents. . . . For terrorists, who must in the nature of their purpose be secretive, . . . we may be able to discover them before they act only if we resort to invasive and substantial surveillance, infiltration, screening, and so forth, all of which might be misused against innocents far more often than they are well used against potential terrorists."Russell Hardin, political scientist, "Civil Liberties in the Era of Mass Terrorism," Journal of Ethics, 2004The purpose of the excerpt could best be used to support which of the following explanations for why policies used to combat terrorism were controversial?Some Americans sought to use new technologies to combat terrorism.Some Americans believed that terrorism had no effect on United States domestic policy.Some Americans saw Cold War policies as providing insight into how to prevent current terrorist actions.Some Americans worried that the freedoms of United States citizens might be violated by the efforts to stop terrorism.
