How do you do these questions and explanations please?

Answers

Step-by-step explanation:

1. Standard error is SE = σ / √n.  As n increases, SE decreases.

2. Degrees of freedom is d = n − 1.  As n increases, d increases.

3. The t statistic is t = (x − μ) / SE.  As SE decreases, t increases.

4. As n increases, t* decreases and approaches z*.

5. As the t statistic increases, the P-value decreases.

6. Margin of error is t* times SE.  As n increases, MoE decreases.

7. The width of the confidence interval is 2 MoE.  As MoE decreases, the width of the confidence interval decreases.

Over the past few years, there has been a strong positive correlation between the annual consumption of diet soda drinks and the number of traffic accidents.


(a) Do you think increasing consumption of diet soda drinks causes traffic accidents? Explain your answer.


No. A strong correlation implies causation.

No. A strong correlation does not imply causation.

Yes. A strong correlation does not imply causation.

Yes. A strong correlation implies causation.



(b) What lurking variables might be causing the increase in one or both of the variables? Explain your answer.

Answers

Answer:No. A strong correlation does not imply causation.

Step-by-step explanation:

Cause and effect relationship is not explained by correlations. A cause and effect relationship can only be established by carrying out carefully controlled experiments.

Hence, a strong correlation between the the intake of soda and accidents does not necessarily imply that soda intake causes accident.

A lurking variable in this study may be the speed of the drivers. A lurking variable is not controlled but significantly impacts results obtained from the study.

Since the speed of the drivers is not strictly controlled, it may just be a lurking variable.

If x^(y)=5^(x-y) then dy/dx=​

Answers

First, rewrite

[tex]x^y=e^{\ln x^y}=e^{y\ln x}[/tex]

[tex]5^{x-y}=e^{\ln5^{x-y}} = e^{\ln(5)(x-y)}[/tex]

Now, differentiate both sides using the chain rule:

[tex]\dfrac{\mathrm d\left(e^{y\ln x}\right)}{\mathrm dx}=\dfrac{\mathrm d\left(e^{\ln(5)(x-y)}\right)}{\mathrm dx}[/tex]

[tex]e^{y\ln x}\dfrac{\mathrm d(y\ln x)}{\mathrm dx}=e^{\ln(5)(x-y)}\dfrac{\mathrm d(\ln(5)(x-y))}{\mathrm dx}[/tex]

[tex]x^y\left(\dfrac{\mathrm dy}{\mathrm dx}\ln x+y\dfrac{\mathrm d(\ln x)}{\mathrm dx}\right)=\ln(5)5^{x-y}\left(\dfrac{\mathrm d(x)}{\mathrm dx}-\dfrac{\mathrm dy}{\mathrm dx}\right)[/tex]

[tex]x^y\left(\ln x\dfrac{\mathrm dy}{\mathrm dx}+\dfrac yx\right)=\ln(5)5^{x-y}\left(1-\dfrac{\mathrm dy}{\mathrm dx}\right)[/tex]

[tex]\left(x^y\ln x+\ln(5)5^{x-y}\right)\dfrac{\mathrm dy}{\mathrm dx}=\ln(5)5^{x-y}-yx^{y-1}[/tex]

[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\ln(5)5^{x-y}-yx^{y-1}}{x^y\ln x+\ln(5)5^{x-y}}[/tex]

For his long distance phone service, Aldo pays a $7 monthly fee plus 7 cents per minute. Last month, aldo's long distance bill was 20.86. For how many minutes was aldo billed

Answers

Answer:

198

Step-by-step explanation:

Bill costs 20.86

monthly fee plus cost per minute = 20.86

7 + (20.86-7) = 20.86

7+13.86=20.86

7+1386cents = 20.86

Minutes Aldo was billed = 1386÷7=198

A large hamburger (e.g., Whopper®) sandwich contains 628 kcal and 36 grams of fat. Approximately what percentage of the total energy is contributed by fat?

Answers

Answer:

Step-by-step explanation:

Total energy of the sandwich = 628kcal

Mass of fat contained = 36grams

Convert gram to kcal

1gram = 9kcal

36 grams = x

x = 36×9

x = 324kcal

Hence the fat contains 324kcal

%fat contained = fat(in kcal)/total calorie × 100%

%fat contained = 324/628 × 100%

%fat contained = 1/2 × 100%

%fat contained = 50%

Hence approximately 50% of the total energy is contributed by fat.

what is the value of the discriminat?

Answers

Answer:

The Discriminant is 25

Step-by-step explanation:

For this case, the discriminant will be given by

b ^ 2 - 4 * a * c

Where

b = 7

a = 3

c = 2

substituting

b ^ 2 - 4 * a * c = (7) ^ 2 - 4 * (3) * (2) = 25

Therefore the value of the discriminant is 25.

Help me three questions please really easy I promise answer Melanie needs 5,000 chocolates for an event. So far, she has bought 2cases of 1,125 chocolates each. How many more does she need? This activity is important because any business that offers multiple product lines to multiple market segments is faced with the task of making the product/market decisions and prioritizing those decisions. Products and market segments that are growing quickly and are very profitable should get more attention and resources than a product and market segment that does not show as much potential. Once a marketing manager creates a market-product grid, they must select which segments to target. To do this, the marketing manager should use several criteria in assessing the different segments. Those criteria include: market size, expected growth, competitive position, cost of reaching the segment, and the compatibility with the organization's objectives and resources. The goal of this exercise is to demonstrate your understanding of the market-product development process by analyzing a gift shop's markets and products. Read the case below and then answer the questions that follow as you consider its markets and product offerings. A small local gift shop recently marked its 25th anniversary of being in business. Over that time, the owners have continually changed the products sold in its store to reflect changes in the market. From the early days of selling small gift-type items such as figurines and collectibles, the store now offers a more eclectic mix of merchandise that includes Vera Bradley purses and inexpensive jewelry, as well as items that could be classified as "gift-type" products and merchandise that is best described as "collectibles." However, the demographics of the store's market, as well as the needs of that market, seem to be changing. There has been an influx of younger customers (20s and 30s) into the area, which has brought the average age of the area down by 9.8 years. This rapidly growing segment doesn't seem interested in buying the same collectibles that their parents bought. Many older residents (60s and 70s) have been leaving the area for retirement. The older customers are still buying the collectibles, but are also buying gifts for children and grandchildren for holidays and special occasions. Indeed, while sales of merchandise aimed at the younger customers have grown 30 percent, sales to the older crowd have been flat. And the younger group has now passed the older segment in terms of the size of the population. While there are other stores in the area selling similar merchandise, this gift shop has managed to get an exclusive on the Vera Bradley line, which has been popular with the younger customers. The owners of the gift shop are considering which market segment should be the focus of their attention and limited resources. This is an especially critical decision because of the limited space in the store and the need to add fixtures for carrying some of the collectible items that are coming on the market. Based on the limited information in the case, which market segment is larger? a) the over-80 segment b) all segments are the same size c) the 60s and 70s segment d) the 20s and 30s segment Plz hellpppgive an example from everyday life that shows the difference between taking responsibility and blaming yourself and explain why the latter takes power away plz help me!!
