Use The Scatter Plot To Answer The Question.A Scatter Plot With Points At (negative 16, Negative 7),

Answers

Answer 1

Using linear regression, the function that best fits the data in the scatter-plot is given by:

f(x) = 1/2x + 1.

How to find the equation of linear regression?

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator. These points are given on a table or in a scatter plot in the context of the problem.

The scatter-plot in this problem contains these following points:

(-16, -7), (-9, -5), (-3, -3), (1, 2), (5, 4), (8, 3) and (14,6).

Inserting these points into a calculator, the equation is given by:

f(x) = 0.46835x + 1.

Approximating the slope to 1/2 considering the given options, the function is given by:

f(x) = 1/2x + 1.

Terrell arranges x roses at $3.50 each with 10 carnations at $2.25 each. He makes a bouquet of flowers that averages $3.00 per flower. Choose an equation to model the situation.

Answers

Answer:
3.5x+22.5/x+10= 3
Step-by-step explanation:
Given,
The number of roses = x,
Price of each rose = $ 3.50,
So, the total price of roses = 3.5x dollars,
Now, the number of carnations = 10,
The cost of each carnation = $2.25,
So, the total cost of all carnations = 10 × 2.25 = $ 22.5,
Thus, the total cost of a bouquet of flowers = ( 3.5x + 22.5 ) dollars,
Also, the total numbers of flower = x + 10,
Hence, the average cost flowers =

According to the question,
The average cost of flowers = $ 3.00

Korey is planning to open a comic book store. His store will cost $12,500 to open and will come with an $8,000 total annual operational cost. If his store makes $12,000 in profit during the first year, and profits increase by 6% each year from then, how long will it take for Korey to see an overall profit in his business (where total profits exceed total expenses)? A = P (1 + r) superscript t

Answers

It will take 3 years for Korey to see an overall profit in his business.

What is a percentage?

A percentage is a number or ratio that represents a fraction of 100. 

We have,

Cost of the store to open = $12500

Cost of the operational cost = $8000

Profit store makes each year = $12000

Profit increase each year = 6%

Profit = Income - Total cost

First-year:

Profit = 12000 - (12500 + 8000) = -8500

There is no profit in the first year.

2nd year:

Profit = 2 x (12000 + 6% of 12000) - (12500 + 2 x 8000)

         = 25440 - 28500

         = -3060

There is no profit in the second year.

Third-year:

Profit =  3 x (12000 + 6% of 12000) - (12500 + 3 x 8000)

         =  38160 - 36500

         = 1660

We see that there is a profit of 1600 in the third year.

Thus,

It will take 3 years for Korey to see an overall profit in his business.

An airplane flies with a constant speed of 804 miles per hour. How far can it travel in 3 hours?

Answers

The distance covered by the aeroplane moving with constant speed is 2412 miles in 3 hours.

What is meant by the speed of the body?The distance moved per unit of time is referred to as speed. It is the rate at which an object moves. The magnitude of a velocity vector is represented by the scalar quantity speed. It lacks a sense of direction. A higher speed indicates that an object moves faster. Lower speed indicates that it is moving more slowly. It has zero speed if it is not moving at all.The formula: is the most common method to count the constant speed of an object traveling in a straight line.

The formula for speed is;

Speed = distance/ time

s = d/t

For the given question,

An air plane flies with a constant speed of 804 miles per hour.

speed 's' =  804 mi / hour.

Time 't' = 3 hours.

Put the values in formula.

804 = d/3

d = 804×3

d = 2412 miles

Thus, the distance covered by the aeroplane moving with constant speed is 2412 miles in 3 hours.

Answers

The value of x from given linear equation is -4.

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

For example, 2x+3=8 is a linear equation having a single variable in it.

Given that x + 16 + x = – 3 x – 4

To find the value of x solving the given linear equation

x + 16 + x = – 3 x – 4

⇒ 2x + 16 = -3x - 4

⇒ 2x + 3x = -4 -16

⇒ 5x = -20

⇒ x = -20/5

If a location on a graph has an indegree of 5 and an outdegree of 10 what is the total degree?

Answers

The total degree when the indegree is 5 and the outdegree of 10 is 15.

The number of head ends next to a vertex is referred to as the vertex's indegree, and the number of the tail ends next to a vertex is referred to as the vertex's outdegree (called branching factor in trees).

The location on a graph has an indegree of 5 and an outdegree of 10.

The sum of the indegree and the outdegree is the total degree of the vertex. The indegree is written as deg−(x) and the outdegree is written as deg+(x).

The total degree will be:

= indegree + outdegree

= deg⁻(x) + deg⁺(x)

= 5 + 10

= 15

The total degree is the sum of in and outdegree is 15.

From 1969 through 1977, there were 24 teams in Major League Baseball, and only 4 made the playoffs
each year. Now, there are 30 teams, and 10 make the playoffs. Find the ratio of teams making the
playoffs to those not making the playoffs in 1969 and today.

Answers

The 1969 Major League Baseball season was contested from April 7 to October 16, 1969. It included the third Major League Baseball expansion of the decade, with the Kansas City Royals, Montreal Expos, San Diego Padres, and Seattle Pilots each beginning play this season. The season was also celebrated as the 100th anniversary of professional baseball, honoring the first professional touring baseball team, the Cincinnati Red Stockings of 1869.

This was the first season of the "Divisional Era". With each league expanding from 10 teams to 12 teams, both leagues were divided into two six-team divisions. Teams continued to play 162-game schedules, in place since 1962, by now playing the other five teams in their own division 18 times each (90 games) and playing the six teams in their league's other division 12 times each (72 games). The winners of each division would advance to the postseason and face each other in a League Championship Series, then a best-of-five series, to determine the pennant winners that would face each other in the World Series.

The Baltimore Orioles won the AL East with an MLB-best 109–53 record, and then defeated the AL West champion Minnesota Twins in three games in the first American League Championship Series. The New York Mets won the NL East division with an NL-best 100–62 record, and then defeated the NL West champion Atlanta Braves in three games in the first National League Championship Series. The "Miracle Mets", having joined the league in 1962, were the first expansion team to win a pennant.

The upstart Mets went on to upset the heavily favored Orioles in the World Series, four games to one, in what is considered one of the greatest upsets in World Series history.[1]

When x < 0, we get

y > 1, as absolute value always give positive value

When x = 1, then we get
