20 PTS! What are the different shapes of a data set? Explain left and right skew and how this affects the mean of a data set.

Thanks, any help is much appreciated! :)

Answers

Answer 1
There are many shapes data sets could show. One example would be a symmetric data set. In this case both sides of the picture would look almost exactly or could be exactly (rarely) alike. In this case the mean could be used as a measure of center.

When the data is skewed right or left, the pictorial representation of the data will show less data points on the side where it is skewed and more data on the opposite side. The tail will be longer on the right if it is skewed right and vice versa.

In data that is skewed right, the mean will be greater than the median and if the data is skewed left, the mean will be less than the median. Tje mean is not the measure of center when the data is skewed.

What is the correct expression of 34,000 x 96,000 using scientific notation?

Answers

3.264 x 109 i got taught this in 5th grade

For this case we have the following product:

[tex] 34000 * 96000
[/tex]

We can rewrite both numbers using scientific notation.

We have then:

[tex] (3,4 * 10 ^ 4) * (9,6 * 10 ^ 4)
[/tex]

Then, we can rewrite the expression as follows:

[tex] (3,4 * 9,6) * (10 ^ 4 * 10 ^ 4)
[/tex]

Same basis, the exponents are added:

[tex] (3,4 * 9,6) * 10 ^ 8
[/tex]

Multiplying the expression within the parenthesis we have:

[tex] (32.64) * 10 ^ 8
[/tex]

Rewriting the left term as scientific notation we have:

[tex] (3,264 * 10 ^ 1) * 10 ^ 8
[/tex]

Finally we have:

[tex] 3,264 * 10 ^ 9 [/tex]

Answer:

the correct expression of 34,000 x 96,000 using scientific notation is:

The number of huckleberries picked during a huckleberry contest are normally distributed with a mean of 300 and a standard deviation of 53. Jill picked 276 huckleberries in the contest.

What percent of huckleberry pickers picked less than Jill?

Round your answer to the nearest whole number.

Answers

The z-score is given by:
z=(x-μ)/σ
where:
μ is the mean
σ is the standard deviation
from the question:
x=276
μ=300
σ=53
substituting the value in our formula we get:
z=(276-300)/53
z=-0.453
the probability associated with this z-score is 0.3264~32.64%
thus the percentage pickers that picked less than Jill is 32.64%~33%

Answer:

Answers

The answers are A and E I believe.

Option A and option E are true, Colleen has the most money in her bank account and Colleen's balance is further from zero dollars than Toby's balance.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given that Colleen has a bank account balance of $16.43.

Toby has a bank account balance of –$10.21.

Yosef has a bank account balance of $8.98.

Colleen has the most money in her bank account is true because $16.43 is greater than $8.98.

So the statement in A is true.

Colleen's balance is further from zero dollars than Toby's balance is also true.

Toby has more money than Colleen is false.

Yosef has less money than Toby is uncertain.

Hence, Option A and option E are true, Colleen has the most money in her bank account and Colleen's balance is further from zero dollars than Toby's balance.

Jeremy 7 years older than Esmeralda in 3 years the sum of their ages will be 57 how old is Jeremy now

Answers

Right now, Jeremy is 29 years old. Esmeralda is currently 22. 
First, define your variables.
J = Jeremy's age
E = Esmeralda's age

Next, create your equations.
J = E + 7
J + 3 + E + 3 = 57 which simplifies to J + E = 51

Now because J is defined in terms of E, substitute E as J into the second equation. E + 7 + E = 51
Next, 2E = 44
E = 22

Now, substitute the value of E into the original equation to find J. J = E + 7. J = 22 + 7. J = 29

Next check by substituting into the second equation. J + E = 51. 22 + 29 = 51.

Jeremy's age: 29
Esmeralda's: 22

Yi and Sue play a game. They start with the number $42000$. Yi divides by a prime number, then passes the quotient to Sue. Then Sue divides this quotient by a prime number and passes the result back to Yi, and they continue taking turns in this way.

For example, Yi could start by dividing $42000$ by $3$. In this case, he would pass Sue the number $14000$. Then Sue could divide by $7$ and pass Yi the number $2000$, and so on.

The players are not allowed to produce a quotient that isn't an integer. Eventually, someone is forced to produce a quotient of $1$, and that player loses. For example, if a player receives the number $3$, then the only prime number (s)he can possibly divide by is $3$, and this forces that player to lose.

Who must win this game, and why? Explain your reasoning in complete sentences. (Don't just show one example of how the game could go. Instead, explain why the same player must always win, no matter what strategy either player tries to use!)

Answers

42000 = 2^4*3*5^3*7, so has 9 prime factors

The player who plays 9th will lose. If only 2 people are playing, that is the person who takes the first turn. The second player in a 2-person game with this starting number will always win.

Suppose 6000 is placed in an account that pays 3% interest compounded each year. Assumed that no withdrawals are made from the account .

Find the amount at the end of one year ?

Find the amount in the account at the end of two year .

Answers

Find the amount at the end of one year? $6180
Find the amount in the account at the end of two year. $6365.4

Final answer:

With a principal amount of $6000 and a 3% annual interest rate compounded yearly, the account balance at the end of one year will be $6180, and at the end of two years, it will be $6365.40.

Explanation:

To calculate the amount of money in an account with compounded interest, we can use the formula [tex]A = P(1 + r/n)^{(nt)[/tex], where A is the amount of money accumulated after n years, including interest, P is the principal amount, r is the annual interest rate (decimal), n is the number of times the interest is compounded per year, and t is the time the money is invested for in years.

For the student's case, with $6000 placed in an account at 3% interest compounded each year with no withdrawals:

To find the amount at the end of one year, we calculate it as [tex]A = 6000(1 + 0.03/1)^{(1\times 1)[/tex], which equals $6000 × 1.03 = $6180.To find the amount at the end of two years, [tex]A = 6000(1 + 0.03/1)^{(1\times 2)[/tex], giving us $6000 × 1.03² = $6365.40.

As such, after one year, the student would have $6180, and after two years, the balance would be $6365.40.

5n + 3 = 2(n + 2) + 3n

-Show All Work!-

Answers

Simplifying
5n + 3 = 2(n + 2) + 3n

Reorder the terms:
3 + 5n = 2(n + 2) + 3n

Reorder the terms:
3 + 5n = 2(2 + n) + 3n
3 + 5n = (2 * 2 + n * 2) + 3n
3 + 5n = (4 + 2n) + 3n

Combine like terms: 2n + 3n = 5n
3 + 5n = 4 + 5n

Add '-5n' to each side of the equation.
3 + 5n + -5n = 4 + 5n + -5n

Combine like terms: 5n + -5n = 0
3 + 0 = 4 + 5n + -5n
3 = 4 + 5n + -5n

Combine like terms: 5n + -5n = 0
3 = 4 + 0
3 = 4

Solving
3 = 4
The left and right sides are not equal, therefore there is no solution.

Answers

[tex] \left \{ {{ \frac{3}{8}x+ \frac{1}{3}y = \frac{17}{14} } \atop {x+7y=8}} \right. [/tex]

To solve this system by substitution, first isolate x in the second equation.

[tex]x+7y=8[/tex]
[tex]x+7y-7y=8-7y[/tex]
[tex]x=8-7y[/tex]

Now, plug this expression ([tex]8-7y[/tex]) for x in the top equation to solve for y.

[tex] \frac{3}{8} (8-7y)+ \frac{1}{3} y= \frac{17}{14} [/tex]

[tex]72-55y=17[/tex]
[tex]-55y=17-72[/tex]

[tex]y=1[/tex]

Now that you have y, plug it into the second equation and solve for x.

[tex]x+7y=8[/tex]
[tex]x+7(1)=8[/tex]
[tex]x+7=8[/tex]
[tex]x=1[/tex]

Last step is to plug your x- and y-values in to both equations to check your work.

[tex] \frac{3}{8} * \frac{3}{3} = \frac{9}{24} ; \frac{1}{3} * \frac{8}{8} = \frac{8}{24} [/tex]

Johan takes out a 20-year mortgage at 4% to buy a house. When he looks at investing in 20-year, fixed-rate Treasuries, which of the following rates is most likely closest to the coupons on the Treasuries? Select the best answer from the choices provided. 2.2% 7.8% 3.9% 9.2%

Answers

Given that Johan takes-out a 20 year mortgage at 4% to buy a house. If he looks at investing in 20-year, fixed rate Treasuries, the most likely closest to the coupons of the treasuries is 3.8%, this is because any other rates apart from this will lead to an arbitrage opportunity. This means that if the percentage of the coupons are high, Johan may invest his proceeds from mortgage to treasuries and earn risk free interest. The right rate is 3.9%

Answer:

3.9%

Step-by-step explanation:

Investing in treasuries is often seeing as a risk free investment since it is sure that they will pay, but the rates are too low, when banks and other finnance corporations set up their mortages and other kinds of large loans interests rates they set them up higher than the fixed rate treasuries since otherwise it´d just be a better deal to put that money on treasuries than lending it to people.

Explain how you would solve a triangles given two sides and the included angle?

Answers

Final answer:

To solve a triangle given two sides and included angle, use the law of cosines. This law is expressed as a² = b² + c² - 2bc cos(A), where a, b, c are the lengths of the sides, and A is the included angle.

Explanation:

To solve a triangle given two sides and the included angle, you would use the Law of Cosines. This law is used when you're given two sides and the included angle in a triangle (often abbreviated as SAS). The law states,

a² = b² + c² - 2bc cos(A)

where a, b, and c are the lengths of the sides of the triangle, and A is the included angle. So, in this case, if you're given sides b and c and included angle A, you would substitute these values into the formula to find side a.

For instance, if side b is 3 units, side c is 4 units, and angle A is 60 degrees, we would substitute these values into our formula like so:  a² = 3² + 4² - 2(3)(4) cos(60).
