Demetri solved this problem using his calculator.
17×0.25=

His answer was 42.5. Which of the following is a mental check Demetri can use to determine that his answer is not reasonable?
A.
When a number is multiplied by 0.25, the decimal point in the answer should be moved 2 places to the right instead of 1 place to the left.
B.
Multiplying by 0.25 is the same as multiplying by 4, so his answer should be close to 16 multiplied by 4.
C.
Multiplying by 0.25 is the same as dividing by 4, so his answer should be close to 16 divided by 4.
D.
When a number is multiplied by 0.25, the decimal point in the answer should be moved 1 place to the right instead of 1 place to the left.

Suppose corn chips cost 32.5 cents per ounce. What would a bag of chips cost if it contained 19 oz? Round your answer to the nearest cent, if
necessary

Answers

Answer:

$6.18 :)

Step-by-step explanation:

617.5 cents would a bag of chips cost if it contained [tex]19[/tex] oz.

What is unitary method?

Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

According to question,

Corn chips costs =  [tex]32.5[/tex] cents per ounce.

A bag of chips of [tex]19[/tex] oz costs = 32.5 * 19

                                               = 617.5 cents

Hence, 617.5 cents would a bag of chips cost if it contained [tex]19[/tex] oz.

Four fundamental factors affect the cost of money: (1) the return that borrowers expect to earn on their investments, (2) the preference of savers to spend their income in the current period rather than delay their consumption until some future period, (3) the risks associated with the investment, and (4) expected inflation. Consider the following statements that address these factors, and indicate which you think are true.
Statement 1: All things being equal, savers and investors expect to receive some amount of maturity premium as compensation for their deferred consumption.
Statement 2: Historical inflation rates, as opposed to expected future rates of inflation, should be used when calculating an investment’s nominal risk-free rate of return.
Statement 3: An investment that can provide a 10% return should attract more investment capital than an otherwise identical investment that can only provide a 6% return.
Statement 4: The inflation premium used to calculate the nominal interest rate on a five-year security should be equal to the rate of inflation expected in year 5 of the investment.
The true statements are:_______.
a. 1, 2, 3, and 4
b. 2 and 4
c. 1, 2, and 3
d. 1 and 3

Answers

Answer:

The true statements are 1 and 3

Step-by-step explanation:

Statement 1 -

All things being equal ,the savers and investors expect to receive some amount of maturity premium as compensation for their deferred consumption.

Statement 3 -

An investment that can provide a 10% return should attract more investment capital than an otherwise identical investment that can only provide a 6% return.

It is true because the return is higher than the return of identical investment  therefore the higher returns will attract more investment.

Statement 2-

It is a false statement.

Historical inflation rates should not be used when calculating an investment’s nominal risk-free rate of return

But the real risk free rate and  inflation premium is the part of prevailing interest rates that results from lenders compensating for expected inflation should be used

Statement 4-

It is a false statement.

The inflation premium used to calculate the nominal interest rate on a five-year security should not be equal to the rate of inflation expected in year 5 of the investment.

∴ we get

Statement 1 and 3 are true.

According to Inc, 79% of job seekers used social media in their job search in 2018. Many believe this number is inflated by the proportion of 22- to 30-year-old job seekers who use social media in their job search. Suppose a survey of 22- to 30-year-old job seekers showed that 308 of the 370 respondents use social media in their job search. In addition, 281 of the 370 respondents indicated they have electronically submitted a resume to an employer.
A) Conduct a hypothesis test to determine if the results of the survey justify concluding the proportion of 22- to 30-year-old job seekers who use social media in their job search exceeds the proportion of the population that use social media in their job search. Use α = 0.05.
1) State the null and alternative hypothesis.
2) Find the value of the test statistic.
3) Find the p-value.
B) Conduct a hypothesis test to determine if the results of the survey justify concluding that more than 70% of 22- to 30-year-old job seekers have electronically submitted a resume to an employer. Using α = 0.05, what is your conclusion?
1) State the null and alternative hypothesis.
2) Find the value of the test statistic.
3) Find the p-value.

Answers

Answer:

A) i) Null hypothesis; p ≤ 0.79

Alternative hypothesis; p > 0.79

ii) test statistic = 2

iii) P-value = 0.02275

B) i) Null hypothesis; p ≤ 0.70

Alternative hypothesis; p > 0.70

ii) test statistic = 2.5

iii) P-value = 0.00621

Step-by-step explanation:

A) We are given;

Population proportion; p = 79% = 0.79

308 of the 370 respondents use social media in their job search. Thus;

Sample proportion; p^ = 308/370 = 0.8324

Let's state the hypotheses;

Null hypothesis; p ≤ 0.79

Alternative hypothesis; p > 0.79

Formula for the test statistic is;

z = (p^ - p)/√(p(1 - p)/n)

z = (0.8324 - 0.79)/√(0.79(1 - 0.79)/370)

z = 0.0424/0.021175

z = 2

From online p-value from z-score calculator attached and using; z = 2; significance value = 0.05; and one tailed distribution, we have;

P-value = 0.02275

B) similar to answer A above, Population proportion; p = 70% = 0.70

But 281 of the 370 respondents use social media in their job search. Thus;

Null hypothesis; p ≤ 0.70

Alternative hypothesis; p > 0.70

Also; Sample proportion; p^ = 281/370 = 0.7595

Formula for the test statistic is;

z = (p^ - p)/√(p(1 - p)/n)

z = (0.7595 - 0.70)/√(0.70(1 - 0.70)/370)

z = 0.0595/0.023824

z = 2.5

From online p-value from z-score calculator attached and using; z = 2.5; significance value = 0.05; and one tailed distribution, we have;

P-value = 0.00621
