Answer:
0.9552
Step-by-step explanation:
Probability of making home can be made by either of the options :-
Prob (Reach through flight) : 1 - prob (flight not cancelled) = 1 - 0.28 = 0.72Prob (Reach through car) : prob (flight cancelled & car seat is available) = 0.28 x 0.84 = 0.2352So, probability of making out at home : Reach through flight or car = 0.72 + 0.2352 = 9.9552
Final answer:
The probability of making it home for the holidays can be calculated using conditional probability. The probability of the flight being canceled is 28 percent, and the probability of Walter having a seat in his car is 84 percent. The probability of making it home is approximately 60.48 percent.
Explanation:
The probability of making it home for the holidays can be calculated using the concept of conditional probability. The probability of the flight being canceled is given as 28 percent, which means there is a 72 percent chance that the flight is not canceled. The probability of Walter having a seat in his car is given as 84 percent. To calculate the probability of making it home, we need to calculate the probability of both events happening.
The probability of the flight not being canceled is 72 percent (0.72) and the probability of Walter having a seat is 84 percent (0.84). To find the probability of both events happening, we multiply the probabilities: 0.72 * 0.84 = 0.6048 or approximately 60.48 percent. So, there is a 60.48 percent probability of making it home for the holidays.

16. Find the mean, median, and range.
Mean =
Median
Range -
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.

Myriad Solutions, Inc., issued 10% bonds, dated January 1, with a face amount of $320 million on January 1, 2013 for $283,294,720. The bonds mature on December 31, 2022 (10 years). For bonds of similar risk and maturity the market yield is 12%. Interest is paid semiannually on June 30 and December 31.
a. What would be the net amount of the liability Myriad would report in its balance sheet at December 31, 2018? 2.
b. What would be the amount related to the bonds that Myriad would report in its income statement for the year ended December 31, 2018?
c. What would be the amount(s) related to the bonds that Myriad would report in its statement of cash flows for the year ended December 31, 2018?
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.
Explanation: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.
In a science fair project, Emily conducted an experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 296 trials, the touch therapists were correct 143 times.
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?
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].

Suppose 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.
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.
Explanation: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.

What is the point-slope form of a line with slope 2/5 that contains the point (-3, 6)?
O A. y-6= -2/5(x+3)
O B. y+6 = 2/5(x+3)
O C. y-6 = 2/5(x+3)
O D.y-3 = 2/5(x+3)
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.

-2x-8y= -32 slope intercept form
Answer:
y = -1/4x +4
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
-2x-8y = -32
Add 2x to each side
-2x+2x-8y =2x -32
-8y = 2x-32
Divide each side by -8
-8y/-8 = 2x/-8 -32/-8
y = -1/4x +4

If sally walked 1/2 mile in 1/4 hour, how fast was she walking measured in miles per hour
2 mile per hour
Step-by-step explanation:
I use the equation :
[tex] \frac{ \frac{1}{2} }{ \frac{1}{4} } = \frac{x}{1} \\ x = \frac{ \frac{1}{2} \times 1}{ \frac{1}{4} } \\ x = \frac{ \frac{1}{2} }{ \frac{1}{4} } \\ x = \frac{1}{2} \times \frac{4}{2} \\ x = \frac{4}{2} \\ x = 2 \: mile[/tex]
So, she walked 2 mile per hour

Write 2 ones and 5 hundredths as a decimal
Answer:
2.05
Step-by-step explanation:
Look at this chart
2 ones and 5 hundredths can be written as 2.05 in decimal form.
What are decimals?Decimals are values that utilize a dot known as the decimal point to distinguish between the whole number portion and the fractional portion. This dot acts as a separator marking the boundary, between these two parts of a number. The fractional section of a decimal can be expressed in units such as tenths, hundredths, thousandths and forth.
In this case the digit 2 signifies the number element of the value while 0.05 represents its fractional component. The presence of the point ensures a division, between these two segments, one being whole and the other being fractional.
