Answer: (7,3)

Step-by-step explanation:

The coordinates of point B(7, 3).

The formula below gives the coordinates of the point A(x, y), which internally splits the line segment between the points P([tex]x_1[/tex],  [tex]y_1[/tex]) and Q([tex]x_2[/tex], [tex]y_2[/tex]) in the ratio [tex]m_1[/tex]: [tex]m_2[/tex],

A (x, y) = [tex]((m_1 x_2 + m_2 x_1) / ( m_1 + m_2), \;\; (m_1 y_2 + m_2 y_1) / ( m_1 + m_2)[/tex]

Given:

Point A is (-7, 5) and point M is at (0, 4).

and, Point M is the midpoint of point A and Point B.

A (x, y) = [tex](m_1 x_2 + m_2 x_1) / ( m_1 + m_2)[/tex]

So, x= [tex](m_1 x_2 + m_2 x_1) / ( m_1 + m_2)[/tex]

0 = ( 1 x [tex]x_2[/tex] + 1 x (-7)) / (1 + 1)

0 = [tex]x_2[/tex] - 7

[tex]x_2[/tex] =7

and, y= [tex](m_1 y_2 + m_2 y_1) / ( m_1 + m_2)[/tex]

4= ( 1 x [tex]y_2[/tex] + 1 x 5)/ 2

8 = [tex]y_2[/tex] + 5

[tex]y_2[/tex] = 3

Hence, the coordinates of B(7, 3).

Answer:

(i) The student who weighed the rock 20 times.

Step-by-step explanation:

The margin of error of a confidence interval is:

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which z is related to the confidence level, [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

From the equation above, the larger the size of the sample, the lower the margin is, that is, the narrower the interval is.

In this question:

A student weighed the rock 20 times and other the 5. From above, the one who weighed the rock 20 times will have the more precise interval.

So the correct answer is:

Answer:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

Answer:

4x-5y =5

Step-by-step explanation:

First we need to find the slope of the line

m = (y2-y1)/(x2-x1)

   = (0-10)/(0- -8)

   = -10/(0+8)

   -10/8  

   -5/4

We want a line with a perpendicular slope

That line will have a negative reciprocal slope

-1 (-5/4)

4/5

We have the slope and a point

y= mx+b is the slope intercept form of a line

y = 4/5x+b

Substitute the point into the equation

3 = 4/5(5)+b

3 =4+b

b = -1

The equation of the line is y = 4/5x-1

Multiply each  side by 5 to get rid of the fractions

5y = 4x -5

Subtract 4x from each side

-4x+5y = -5

Multiply each side by -1

4x-5y =5

Answer:

4x - 5y = 5

Step-by-step explanation:

Slope of the given line:

(-10-0)/(8-0)

-10/8

-5/4

Slope of the Perpendicular line

4/5

y = ⅘x + c

3 = (4/5)(5) + c

3 = 4 + c

c = -1

y = (4/5)x - 1

5y = 4x - 5

4x - 5y = 5

Answer:

a. $ 285,349,947

b.  $ 34,055,227

c. $ 283,294,720 and $ 32,000,000

Step-by-step explanation:

We have the following data as of Jan. 1, 2013:

Cash 283,294,720

Discount on Bonds Payable 36,705,280

Bonds Payable 320,000,000

Now for the date of June 30, 2013, we do the following calculations:

320,000,000 x 10% x 2 = $ 16,000,000 cash payment

interest expense:

283,294,720 carrying value x 6% market rate = 16,997,683

to calculate depreciation:

16,997,683 - 16,000,000 = $ 997,683 discount amortization

Now for the new carrying value of bonds, we do the following:

283,294,720 + 997,683 = 284,292,403

As of Dec. 31, 2013, we have to:

320,000,000 x 10% x 2 = $ 16,000,000 cash payment

interest expense:

284,292,403 carrying value x 6% market rate = 17,057,544

to calculate depreciation:

17,057,544 - 16,000,000 = $ 1,057,544 discount amortization

Now for the new carrying value of bonds, we do the following:

284,292,403 + 1,057,544 = 285,349,947

Answering the questions:

a. The bonds would be listed at their current carrying value, $ 285,349,947

b. Interest Expense : 16,997,683 + 17,057,544 = $ 34,055,227

c. The $ 283,294,720 cash received from the sale of bonds would be added to cash flows under financing activities. The $ 32,000,000 in interest payments would be subtracted from cash flows under operating activities.

The net amount of liability, amount in income statement, and cash outflows related to Myriad Solutions, Inc.’s bonds are all calculated based on semiannual interest payments and the amortization of the discount over the life of the bonds. The carrying value of the bonds increases each year, and the interest expense and cash payments are reported in the financial statements.

To determine the net amount of the liability Myriad Solutions, Inc. would report in its balance sheet at December 31, 2018, we need to calculate the carrying value of the bonds five years after issuance. Assuming the bonds were issued at a discount because the market rate of 12% was higher than the coupon rate of 10%, the discount is being amortized over the life of the bonds. This means the liability in the balance sheet is increasing every year until it reaches the face value at maturity.

The amount related to the bonds that Myriad would report in its income statement for the year ended December 31, 2018, includes the interest expense. Since the interest is paid semiannually, there would be two interest payments in 2018. Each payment would be a portion of the annual 10% coupon rate on the face value of $320 million, adjusted for any amortization of the bond discount over the reporting period.

For the statement of cash flows for the year ended December 31, 2018, Myriad would report the actual cash paid out as interest payments on the bonds. This would total the semiannual payments made on June 30 and December 31, which would be 10% of the $320 million face value divided by two, reflecting that interest is paid semiannually.

Answer:

68% of buyers paid between $147,700 and $152,300.

Step-by-step explanation:

We are given that prices of a certain model of a new home are normally distributed with a mean of $150,000.

Use the 68-95-99.7 rule to find the percentage of buyers who paid between $147,700 and $152,300 if the standard deviation is $2300.

Let X = prices of a certain model of a new home

SO, X ~ Normal([tex]\mu=150,000 ,\sigma=2,300[/tex])

The z score probability distribution for normal distribution is given by;

                             Z  =  [tex]\frac{X-\mu}{\sigma}[/tex]  ~ N(0,1)

where, [tex]\mu[/tex] = population mean price = $150,000

            [tex]\sigma[/tex] = standard deviation = $2,300

Now, according to 68-95-99.7 rule;

Around 68% of the values in a normal distribution lies between [tex]\mu-\sigma[/tex] and [tex]\mu-\sigma[/tex].

Around 95% of the values occur between [tex]\mu-2\sigma[/tex] and [tex]\mu+2\sigma[/tex] .

Around 99.7% of the values occur between [tex]\mu-3\sigma[/tex] and [tex]\mu+3\sigma[/tex].

So, firstly we will find the z scores for both the values given;

         Z  =  [tex]\frac{X-\mu}{\sigma}[/tex]  =  [tex]\frac{147,700-150,000}{2,300}[/tex]  = -1

         Z  =  [tex]\frac{X-\mu}{\sigma}[/tex]  =  [tex]\frac{152,300-150,000}{2,300}[/tex]  = 1

This indicates that we are in the category of between [tex]\mu-\sigma[/tex] and [tex]\mu-\sigma[/tex].

SO, this represents that percentage of buyers who paid between $147,700 and $152,300 is 68%.

Approximately 95% of the buyers paid between $147,700 and $152,300.

To find the percentage of buyers who paid between $147,700 and $152,300, we can use the 68-95-99.7 rule for normal distributions. According to this rule, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

The mean of the prices is $150,000 and the standard deviation is $2,300. The difference between $147,700 and $152,300 is $4,600, which is 2 standard deviations away from the mean. Therefore, we can expect approximately 95% of buyers to have paid between $147,700 and $152,300.

So, approximately 95% of the buyers paid between $147,700 and $152,300.

Answer:

a 0.5

b 0.4831

c 0.4354 < P < 0.53008

Step-by-step explanation:

Given that :

Probability (P) of a head or a tail when a coin is being tossed or flipped = 1/2 = 0.5

Sample size (n) = 296

Selected sample (X) = 143

a) Given that Emily used a coin toss to select either her right hand or her left hand, what proportion of correct responses would be expected if the touch therapists made random guesses?

The  proportion of correct responses that would be expected if the touch therapists made random guesses is 0.5

b) Using Emily's sample results, what is the best point estimate of the therapists' success rate?

Point estimate [tex](p') = \frac{X}{n}[/tex]

= [tex](p') = \frac{143}{296}[/tex]

= 0.4831

c) Using Emily's sample results, construct a 90% confidence interval estimate of the proportion of correct responses made by touch therapists.

The [tex]Z_c[/tex] for 90% is 1.645

Using the formula P" -E < P < P" + E

where E = margin of error :  [tex]Z_c * \sqrt{\frac{P(1-P)}{n} }[/tex]

[tex]=1.645 * \sqrt{\frac{0.4831(0.5169)}{296} }[/tex]

[tex]=1.645 * \sqrt{\frac{0.2497}{296} }[/tex]

[tex]=1.645*0.029[/tex]

= 0.0477

∴ P" -E < P < P" + E

= 0.4831 - 0.0477 < P < 0.4831 + 0.0477

= 0.4354 < P < 0.53008

Answer:

The proportion of correct responses would be in between [tex](0.4345)<P<(0.53008)[/tex]

Step-by-step explanation:

Given information:

Sample size [tex](n)=296[/tex]

Selected sample [tex](x) =143[/tex]

Probability of head or tail will be 0.5 because a coin is tossed.

So the proportion of correct responses if the therapist made random decision will be 0.5.

Now with the help of sample result:

Point estimate:

[tex](p)'=x/n\\(p')=143/296\\(p')=0.4831[/tex]

Now, if we take confidence level of 90%

Then, [tex]Z=1.645[/tex]

As,

[tex](P"-E)<(P)<(P"+E)[/tex]

Where , E is the margin of error.

[tex]E=Z \times \sqrt \frac{P(1-P)}{n} \\E=1.654 \times \sqrt \frac{(0.4831 \times0.5169}{296} \\E=1.645\times 0.029\\E=0.0477[/tex]

Therefore:

[tex](P"-E)<(P)<(P"+E)[/tex]

[tex](0.4831-0.0477)<P<(0.4831+0.0477)\\(0.4345)<P<(0.53008)[/tex]

Hence, the proportion of correct responses would be in between [tex](0.4345)<P<(0.53008)[/tex].

The correct student is Dean.

To determine which student is correct, let's analyze the information given in the box plots for both classes:

For Mr. Yan's class, the box plot shows:

- Minimum value (lower whisker): 1

- Maximum value (upper whisker): 9

- Lower quartile (Q1): 2

- Median (Q2): 4

- Upper quartile (Q3): 7

- Interquartile range (IQR): Q3 - Q1 = 7 - 2 = 5

For Mrs. Gonzalez's class, the box plot shows:

- Minimum value (lower whisker): 1

- Maximum value (upper whisker): 9

- Lower quartile (Q1): 4

- Median (Q2): 5.5

- Upper quartile (Q3): 7

- Interquartile range (IQR): Q3 - Q1 = 7 - 4 = 3

Now let's evaluate each student's statement:

- Nadine: The medians are the same because both sets of data have the same minimum and maximum values. This statement is incorrect because the medians are different. Mr. Yan's class has a median of 4, while Mrs. Gonzalez's class has a median of 5.5.

- Kendrick: Mr. Yana's class has a greater median because the box in that box plot is larger. This statement is incorrect because the size of the box does not determine the median. The median is the value that divides the data into two equal halves, and it is indicated by the line inside the box.

- Tahara: Mrs. Gonzalez's class has a greater median because the line inside that box is located at a greater value. This statement is correct. The median for Mrs. Gonzalez's class is 5.5, which is greater than the median for Mr. Yan's class, which is 4.

- Dean: The medians are both 7 because the upper quartile for the sets of data is 7. This statement is incorrect because the median is not determined by the upper quartile but by the value that separates the higher half from the lower half of a data sample.

Therefore, the only correct statement is made by Tahara, who correctly identifies that Mrs. Gonzalez's class has a greater median because the line inside the box is located at a greater value (5.5) compared to Mr. Yan's class (4).

Answer:

y -6 = 2/5(x+3)

Step-by-step explanation:

The point slope form of an equation is

y -y1 = m(x-x1)

where m is the slope and (x1,y1) is the point

y -6 = 2/5(x- -3)

y -6 = 2/5(x+3)

C.) y - 6 = 2/5(x + 3)

The original point slope equation is the following

[tex]y - y_1 = m(x-x_1)[/tex]

When you plug in negative point values into this equation, the sign changes from '-' to '+'. This is how you can determine which equation accurately represents the line.
