Answers

Answer 1

The correlation coefficient measures the relationship between the two variables

The correlation coefficient is 0.234

How to determine the correlation coefficient

The formula of correlation coefficient is:

[tex]r = \frac{1}{n - 1} * \sum{(\frac{x - \bar x}{\sigma_x})*(\frac{y - \bar y}{\sigma_y})[/tex]

Using the dataset from the complete question, we have:

[tex]r = \frac{1}{5 - 1} * 0.9375[/tex]

Evaluate the difference

[tex]r = \frac{1}{4} * 0.9375[/tex]

Evaluate the quotient

[tex]r = 0.234375[/tex]

Approximate

[tex]r = 0.234[/tex]

Hence, the correlation coefficient is 0.234

A family is purchasing a house and needs to finance a $195,000 mortgage from the bank with an annual percentage rate (APR) of 5.3%. The family is financing it over 30 vears and making monthly payments. What would their monthly payment be?​

Answers

Answer:

  a) payment: $1082.84

  b) interest: $194,822.40

Step-by-step explanation:

The monthly payment on the mortgage can be found using the given formula with the given values of principal (P=195000), interest rate (r=0.053), and time period (t=30). The value of n is 12, corresponding to the number of months in a year.

a)

The monthly payment is ...

  [tex]k=\left(1+\dfrac{r}{n}\right)^{nt}=\left(1+\dfrac{0.053}{12}\right)^{12\cdot30}\approx 4.88661119\\\\\text{monthly payment}=\dfrac{P\cdot\dfrac{r}{n}\cdot k}{k-1}=\dfrac{195000\cdot0.0044166667\cdot4.88661119}{4.88661119-1}\\\\\boxed{\text{monthly payment}=\$1082.84}[/tex]

__

b)

The interest owed is the difference between the total of monthly payments and the principal of the loan:

  interest owed = (360)(1082.84) -195000 = 194,822.40

The interest owed over 30 years is $194,822.40.

Basic theorems on similarity of triangles

Theorem 1 :- SSS Similarity

When all the three sides of one triangle are in proportion to the other three sides of the another triangle then those 2 triangles are similar by SSS similarity .

Theorem 2 :- AA similarity

When the two corresponding angles of one triangle are congruent to other two corresponding angles of another triangle then both the triangles are similar by AA Similarity .

Theorem 3 :- SAS similarity

When the two sides of one triangle are in proportion to the other two sides of another triangle and the one of the angles of both the triangles that lie between two corresponding sides are equal then both the triangles are similar by SAS similarity.

Theorem 4 :- AAA similarity

When all the three angles of one triangle are equal to other three angles of another triangle then both the triangles are similar by AAA similarity.

Let's Begin :-

Here, We have given statement that

" If an angle of one triangle is congruent to an angle of another triangle and the corresponding sides including those angles are in proportion, then the two triangles are similar . "

From above theorem, we can conclude that

Both the triangles are similar by SAS similarity

Hence, Option C is correct

[tex]\bold{\huge{\underline{ Solution \: 2 }}}[/tex]

The given statement is proved by using Pythagorean theorem.

Pythagorean theorem states that the square of hypotenuse that is longest side is equal to the sum of the squares of base and perpendicular height that is the smallest sides of the given triangle.

That is,

(5x7) + (5x9) = 5x (7+?

Answers

Answer:

9

Step-by-step explanation:

this is because it is 9 and it could be 9

Answer:

First let's find what (5x7) + (5x9) equals;

(5x7) + (5x9)

35 + 45

= 80

Now 80 has to equal to;

5 x (7 + y) ( where 'y' is our unknown number)

So we set up the equation:-

80 = 5 x (7 + y)

80 = 35 + 5y

-35      -35

45 = 5y

/5    /5

9 = y

Let's double check:

80 = 5 x (7 + y)

80 = 5 x (7 + 9)

80 = 35 + 45

80 = 80, we are correct.

Step-by-step explanation:

Given equation:

7y - 4 = 9y + 13 - 4y

Collect like terms:

7y - 4 = 9y - 4y + 13

Combine like terms:

7y - 4 = 5y + 13

Subtract 5y from both sides:

2y - 4 = 13

Add 4 to both sides:

2y = 17

Divide both sides by 2:

y = 17/2

How many whale sharks would a researcher need to measure so that 90% confidence level would have a margin of error of 0.25

Margin of error is used to determine by what value there is deviation from the real value. Margin of error (E) is given by:

[tex]E=Z_\frac{\alpha}{2} *\frac{standard\ deviation}{\sqrt{sample\ size} }[/tex]

The 90% confidence level have a z score of 1.645. Hence for E = 0.25, standard deviation = 5.7 feet, hence:

5.16 Identify hypotheses, Part II: Write the null and alternative hypotheses in words and then symbols for each of the following situations. (a) Since 2008, chain restaurants in California have been required to display calorie counts of each menu item. Prior to menus displaying calorie counts, the average calorie intake of diners at a restaurant was 1100 calories. After calorie counts started to be displayed on menus, a nutritionist collected data on the number of calories consumed at this restaurant from a random sample of diners. Do these data provide convincing evidence of a difference in the average calorie intake of a diners at this restaurant?

Answers

Answer:

H₀: µ = 1100 vs. Hₐ: µ ≠ 1100.

Step-by-step explanation:

A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.  

It is a hypothesis of no difference.

It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.

For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.

Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.

The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.

It is also known as the research hypothesis and is denoted by Hₐ.

In this case the hypothesis can be defined as follows:

Null hypothesis:

H₀: The average calorie intake of a diner at this restaurant is 1100, i.e. µ = 1100.

Alternate hypothesis:

Hₐ: The average calorie intake of a diner at this restaurant is different from 1100, i.e. µ ≠ 1100.

Lets follow a bills journey to become law. The Bill Begins Laws begin as ideas. These ideas may come from a Representativeor from a citizen like you. Citizens who have ideas for laws can contact their Representatives to discuss their ideas. If the Representatives agree, they research the ideas and write them into bills. The Bill Is Proposed When a Representative has written a bill, the bill needs a sponsor. The Representative talks with other Representatives about the bill in hopes of getting their support for it. Once a bill has a sponsor and the support of some of the Representatives, it is ready to be introduced.
