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.

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:

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    

Answer:the two equations that model the situation are

x + y = 48

3x + 2y = 15

Step-by-step explanation:

Let x represent the total number of hours that Derek worked.

Let y represent the total number of hours that Donnie worked.

Derek and Donnie mow 15 lawns over two 2 days. There are 24 hours in a day. Therefore, the number of hours in 2 days would be 2 × 24 = 48 hours. Therefore

x + y = 48 - - - - - - - - - -1

If Derek mows 3 lawns per hour and Donnie mows 2 lawns per hour, it means that

3x + 2y = 15 - - - - - - - - - 2

Answer:

True

Step-by-step explanation:

Sample size selection is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is important in any empirical statistical study in which the goal is to make inferences about a population from a sample. The actual sample size used in a study is determined based on the time money and technical cost of data collection, and the need to have sufficient statistical accuracy.

Finding a balance between acceptable error and research cost gives rise to concepts like Confidence Interval and Margin of Error.

Answer:

The question is incomplete, this is the complete question.;

There are five nickels, five dimes and five quarters in your pocket. You randomly pick three coins and place them on the counter the first coin is a nickel, the second is a dime and the third is a quarter.find the probability of this occurring.

The answer to the question is;

the probability of this occurring is 1/27

Step-by-step explanation:

Let n(N) =5 ( the number of nickels)

n(D) =5 ( the number of dimes) and

n(Q) = 5 ( the number of quarters)

P(N)= 5/15=1/3 (prob of picking a nickel)

P(D) =5/15=1/3 (prob of picking a dime)

P(Q) = 5/15= 1/3 (prob of picking a quatre)

The probability of picking the three= P(N)×P(D)×P(Q)

= 1/3×1/3×1/3

= 1/27

Answer:

His conclusion was incorrect.

Step-by-step explanation:

Since, slope of a line passes through [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is,

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Thus, the slope between (-1, 4) and (0, 0),

[tex]m_1=\frac{0-4}{0+1}=-4[/tex]

Also, the slope between (2, 7) and (3, 3),

[tex]m_2=\frac{3-7}{3-2}=\frac{-4}{1}=-4[/tex]

Now,

There are two cases possible,

Case 1 : line passes through (-1, 4) and (0, 0) is parallel to line passes through (2, 7) and (3, 3)

Case 2 : (-1, 4), (0, 0), (2, 7) and (3, 3) are on the same line

Hence, we can not say that they are on same line only after getting same slope.

i.e. his conclusion was incorrect.

Answer:

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

Step-by-step explanation:

Answer:

0

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.

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.

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.
