Answer:

At 20 miles both companies cost will be same.

Step-by-step explanation:

Let Number of miles be 'x'.

Given:

Quick movers charges $50 a day and $0.50 per mile .

So we can say Total charge is equal to sum of per day charge plus number of miles multiplied by cost of per mile.

framing in equation form we get;

Quick movers charges = [tex]50+0.5x[/tex]

Also Given:

ABC movers charges $45 a day and $0.75 per mile .

So we can say Total charge is equal to sum of per day charge plus number of miles multiplied by cost of per mile.

framing in equation form we get;

ABC movers charges = [tex]45+0.75x[/tex]

We need to find the number of miles at which both companies cost are are same.

Solving to find the same we get;

[tex]50+0.5x=45+0.75x[/tex]

Combining like terms we get;

[tex]0.75x-0.5x=50-45\\\\0.25x=5[/tex]

By Division property of equality we will divide both side by 0.25 we get;

[tex]\frac{0.25x}{0.25} =\frac{5}{0.25} \\\\x= 20 \ miles[/tex]

Hence at 20 miles both companies cost will be same.

Final answer:

By setting up an equation to equate the charges of Quick Movers and ABC Movers, it is determined that at 20 miles, the costs for both companies will be the same.

Explanation:

To find at how many miles the cost for both Quick Movers and ABC Movers is the same, we set up an equation where the cost of each company is equal. Quick Movers charges $50 a day plus $0.50 per mile, and ABC Movers charges $45 a day plus $0.75 per mile. Let's use m to represent the miles.

The equation based on the costs given will be:

50 + 0.50m = 45 + 0.75m

To solve the equation, we first bring all the m terms to one side and the constants to the other:

0.50m - 0.75m = 45 - 50

This simplifies to:

-0.25m = -5

Dividing both sides by -0.25, we find:

m = 20

Therefore, the cost for both companies is the same at 20 miles.

Answer:

Step-by-step explanation:

Injective functions or One to one functions are functions in each one element of A set is is mapped to another element of B set

1) Let's start by listing supposition and their respective Reasons

Suppose:

[tex]g\circ f[/tex] is injective then [tex]f:A\rightarrow B[/tex] is also injective.

Reason: Given

2) Since we are dealing with injective (one to one) functions,  we can rightly proceed:

[tex]f(x)=f(y) \:such \:as\: x,y \in A[/tex]

[tex]g(f(x))=g(f(y))[/tex]

Given the fact that [tex]g\circ f[/tex]

[tex]x=y[/tex]

Then we can say that since [tex]g\circ f[/tex]  f: A is an injective too ("one to one" ) function.

Answer:

a) has the same probability of being selected

Step-by-step explanation:

A simple random sampling means that each possible sample of size n has the same probability of being selected.

Then your answer is:

a) has the same probability of being selected

The definition of a simple random sampling method implies that each possible sample of a given size has an equally likely chance of being selected. Hence, option a. 'has the same chance of being selected' is the correct answer.

The simple random sampling method is a statistical method used to select individual samples from a large population where each sample is given an equal chance of being selected. In a simple random sampling of size n from a finite population of size N, each possible sample of size n would have the same probability of being selected. Therefore, the correct answer is a. has the same probability of being selected.

It is crucial to note that the probability of a sample being selected is not dependent on its size (n) nor the total size of the population (N), as options b, c, and d suggest. Instead, it is determined solely by the sampling method, i.e., simple random sampling.

Answer:

The age of Sleepy is 1 .

Then the age of Scoopy is 9.

The age of Doc would be 45.

Step-by-step explanation:

We have to find the ages of all the three people based on the given equations.

Let the age of Sleepy be  x. Since Scoopy is 8 years older than Sleepy, the age of Scoopy would be (x+8).

Also Doc is 5 times as old as Scoopy so his age is 5(x+8).

Now the sum of the ages of all three is 55.

Writing equation for this,

x + x + 8 + 5(x+8) = 55

7x + 48 = 55

7x = 7

x = 1

So the age of Sleepy is 1 .Then the age of Scoopy is 9.

The age of Doc would be 45.

By solving the linear equations given by the problem, it is found that Scoopy is 10 years old, Sleepy is 2 years old, and Doc is 50 years old.

This problem is a system of linear equations, a topic in the field of mathematics. The task is to find out the age of Sleepy, Scoopy, and Doc. Let's denote Scoopy's age as 'S', Sleepy's age as 'S - 8' (since Sleepy is eight years younger than Scoopy), and Doc's age as '5S' (since Doc is 5 times as old as Scoopy). The equations can be written as below:

It is known that the sum of their ages is 55, which gives us our second equation:

S + (S - 8) + 5S = 55

By solving this equation, we find that S = 10. So Scoopy is 10 years old. Accordingly, Sleepy is 10 - 8 = 2 years old and Doc is 5 * 10 = 50 years old.

Answer:

A =    441  in²  

Step-by-step explanation:

An isosceles right triangle is a triangle with two equals sides (the legs ). In this particular case the base of the triangle will be the length of one side and at the same time the height of the triangle will be the other leg.  Hypotenuse as always is the opposite side to the right angle.

The area of a triangle is

A =  (1/2) * b* h

If we are going to compute the area of such triangle we have to find the length of one side That will be the base of the triangle and at the same time that will be the height of the triangle.

In any right triangle  hypotenuse is:

H²  = L₁²  +  L₂²    (1)

As was explain before  in this particular case  L₁  = L₂

Then

H²  =  L₁² +  L₁²    ⇒    H²  =  2 L₁²        H  =  √2 * L₁      ⇒   L₁  =  42/√2  

Then area of the  

A = (1/2)* ( 42/√2) *   ( 42/√2 )    ⇒     A = 1/4 * (42)²  

A =    441  in²

Step-by-step explanation:

Slope of a line which passes through two points (x1,y1) and (x2,y2) is given by:

\frac{y2-y1}{x2-x1}

(x1,y1) = (-3,2)

(x2,y2) = (1,2)

Substituting the values in the equation to determine the slope of the line:

= \frac{2-2}{1-(-3)}

= \frac{0}{4}

=0

So the slope of the given line is 0.

This is intuitively evident as well as the y coordinates of the two given points are the same.

Okay so this picture is basically the answer for anyone who needs it...

Step-by-step explanation:

Final answer:

Using the Central Limit Theorem, the probability that the stock's price will exceed $105 on the 10th day is calculated to be approximately 13.14%, assuming that the daily change of the stock price is a random variable with a mean of 0 and a variance of 2 and starting from a stock price of $100.

Explanation:

The question is asking to calculate the probability that a company's stock price will exceed $105 on the 10th day, given that the stock price today is $100 and that the daily change of price is a random variable with a mean of 0 and a variance of 2. To answer this, we can use the Central Limit Theorem (CLT) since we have a sum of independent and identically distributed random variables. According to the CLT, the sum of these random variables (or the stock price on the 10th day) will approximate a normal distribution as the number of days increases. For the 10th day, the expected price is the initial price (which is $100) plus 10 times the expected daily change (10*0 = 0), so the expected price is still $100. The variance of the sum of the daily changes is 10 times the variance of a single day (10*2), which equals 20, and the standard deviation is the square root of the variance, which is approximately 4.47.

We are trying to find the probability that the stock price is greater than $105. To do this, we convert the stock price into a z-score using the formula:

z = (X - μ) / σ

where X is the stock price we are interested in ($105), μ is the mean of the stock price on the 10th day ($100), and σ is the standard deviation (approximately 4.47). So we have:

z = (105 - 100) / 4.47 = 1.12

Using standard normal distribution tables or a calculator, we find that the probability of a z-score being greater than 1.12 is approximately 0.1314 (or 13.14%). Therefore, the probability that the stock's price will exceed $105 on the 10th day is about 13.14%.

Answer: Second triangle.

Step-by-step explanation:

For this exercise you need to use the Pythagorean Theorem. Based on it, you know that in a right triangle:

[tex]a^2=b^2+c^2[/tex]

Where "a" is the hypotenuse of the right triangle and "b" and "c" are the legs.

In this case you can identify that the legs of the first triangle and the legs of the second triangle are equal. These are:

[tex]b=7\\c=3.3[/tex]

Knowing their values, you can substitute them into the Pythagorean Theorem and solve for "a":

[tex]a^2=(7)^2+(3.3)^2\\\\a=\sqrt{(7)^2+(3.3)^2}\\\\a=7.738[/tex]

Therefore, you can conclude that the triangle that is closest to being a right triangle is the second one.

Total Number of Coconuts which fell from tree are 14.

Step-by-step explanation:

Given:

Some coconuts fall out of a tree.

Mercy is greedy and takes half,

Joe grabs what he can, and gets five more than Frank.

Frank gets one coconut.

We need to find Total number of coconuts fell from tree.

Number of Coconuts franks has = 1

Now Given that Joe grabs what he can, and gets five more than Frank.

Number of Coconuts Joe has = Number of Coconuts franks has + 5 = 1 + 5 = 6

Also Given Mercy is greedy and takes half.

It means mercy took half of coconuts and rest half were took by Frank and Joe

Hence Number of Coconuts Mercy has = Number of Coconuts franks has +  Number of Coconuts Joe has = 6 + 1 = 7

Now Total Number of Coconuts is equal to sum of Number of Coconuts Mercy has and Number of Coconuts Joe has and Number of Coconuts frank has.

Total Number of Coconuts = 7 + 1 + 6 = 14

Hence Total Number of Coconuts which fell from tree are 14.

Answer:

(2, 2)

Step-by-step explanation:

According to the distance formula, the distance between two points is:

d² = (x₂ − x₁)² + (y₂ − y₁)²

If one point is (x, y) and the other point is (1, 4), then:

d² = (x − 1)² + (y − 4)²

We know y² = 2x, so x = ½ y².  Substituting:

d² = (½ y² − 1)² + (y − 4)²

The minimum distance is when dd/dy equals 0.  We can either simplify first by distributing, or we can immediately take the derivative using chain rule.

If we distribute and then take the derivative:

d² = ¼ y⁴ − y² + 1 + y² − 8y + 16

d² = ¼ y⁴ − 8y + 17

2d dd/dy = y³ − 8

If we use chain rule instead without distributing:

2d dd/dy = 2(½ y² − 1) (y) + 2(y − 4)

2d dd/dy = y³ − 2y + 2y − 8

2d dd/dy = y³ − 8

Setting dd/dy equal to 0:

0 = y³ − 8

y = 2

x = ½ y²

x = 2

(2, 2) is the point on the parabola closest to (1, 4).
