1 Mickey Mantle = 3 Babe Ruth

melisa1 [442]

Answer:

F. Lou Gehrig

Step-by-step explanation:

1 Mickey Mantle = 3 Babe Ruth , therefore:

Mickey Mantle>Babe Ruth

2 Lou Gehrig = 8 Ted Williams , therefore:

Lou Gehrig>Ted Williams

4 Mickey Mantle = 6 Hank Aaron , therefore:

Mickey Mantle>Hank Aaron

4 Ted Williams = 12 Hank Aaron, therefore:

Ted Williams>Hank Aaron

If:

4 Mickey Mantle = 6 Hank Aaron

Then multiplying by 2:

8 Mickey Mantle = 12 Hank Aaron
Recall: 4 Ted Williams = 12 Hank Aaron

Then comparing:

4 Ted Williams=8 Mickey Mantle which means Ted Williams>Mickey Mantle

Now, we can attempt to order them:

Mickey Mantle>Babe Ruth

Lou Gehrig>Ted Williams

Mickey Mantle>Hank Aaron

Ted Williams>Hank Aaron

Ted Williams>Mickey Mantle

Lou Gehrig>Ted Williams>Mickey Mantle>(Hank Aaron and Babe Ruth)

We can see that since Lou Gehrig>Ted Williams, then the Lou Gehrig's card is the most valuable.

Answer:

a. Identify the population of interest in this study.

all the population of the country

b. Identify the sample for the study.

50 adults (the ones that were surveyed)

c. Identify the parameter of interest in the study.

the parameter of interest is the people that believe that coffee shops are overpriced

d. Find and interpret a 95% confidence interval for the parameter of interest.

z score for a 95% confidence level = 1.96

margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579

95% confidence level interval:

0.4 - 0.13579 = 0.26421

0.4 + 0.13579 = 0.53579

95% confidence interval (0.26421 , 0.53579)

aleksandr82 [10.1K]

Answer: $\$1100$

Step-by-step explanation:

Given

Principal amount is $P=\$4000$

Rate of interest $R=5\%$

Time period $T=5\ yr\ \text{and}\ \text{6 months}\equiv 5.5\ yr$

We know, Simple interest is

$\Rightarrow S.I.=\dfrac{P\times R\times T}{100}$

Putting values

$\Rightarrow S.I.=\dfrac{4000\times 5\times 5.5}{100}=\$1100$

Sara gets $\$1100$ after 5 years and 6 months
