Heat energy transferred in the form of waves is called_________.

Answer:

Confidence levels are expressed as a percentage (for example, a 95% confidence level). It means that should you repeat an experiment or survey over and over again, 95 percent of the time your results will match the results you get from a population (in other words, your statistics would be sound!). Confidence intervals are your results…usually numbers. For example, you survey a group of pet owners to see how many cans of dog food they purchase a year. You test your statistics at the 99 percent confidence level and get a confidence interval of (200,300). That means you think they buy between 200 and 300 cans a year. You’re super confident (99% is a very high level!) that your results are sound, statistically.

Confidence Interval For a Sample: Steps

Question:

A group of 10 foot surgery patients had a mean weight of 240 pounds. The sample standard deviation was 25 pounds. Find a confidence interval for a sample for the true mean weight of all foot surgery patients. Find a 95% CI.

Step 1: Subtract 1 from your sample size. 10 – 1 = 9. This gives you degrees of freedom, which you’ll need in step 3.

Step 2: Subtract the confidence level from 1, then divide by two.

(1 – .95) / 2 = .025

Step 3: Look up your answers to step 1 and 2 in the t-distribution table. For 9 degrees of freedom (df) and α = 0.025, my result is 2.262.

Step 4: Divide your sample standard deviation by the square root of your sample size.

25 / √(10) = 7.90569415

Step 5: Multiply step 3 by step 4.

2.262 × 7.90569415 = 17.8826802

Step 6: For the lower end of the range, subtract step 5 from the sample mean.

240 – 17.8826802 = 222.117

Step 7: For the upper end of the range, add step 5 to the sample mean.

240 + 17.8826802 = 257.883

That’s how to find the confidence interval for a sample, hope that helped!

ANSWER:

The best strategy for avoiding ATM fees is to use the ATMs that are within your bank’s account.

EXPLANATION:  

When ATMs from other banks are used, certain fees will be charged to balance the high amount of withdrawal and to compensate for the foreign exchange rate that is experienced by the banks. If you use ATMs within your bank account, no extra fees will be charged for any transactions or withdrawal of money.

The best strategy for avoiding ATM fees is to only C: use ATMs in your bank's network.

What's the best strategy for avoiding ATM fees?

When you use ATMs from your bank's network, you usually don't have to pay extra fees for taking out money. This means you can take out money without having to pay any extra fees.

If you only use ATMs near your home or ATMs you have used before, it doesn't always mean you won't have to pay fees. The fees you are charged depend on who owns the ATM and the network it is a part of, not just where it is located. Moreover, it may not always be convenient or possible to rely solely on ATMs for cash withdrawals.

Hence option C is correct.

Answer:

7/3 mi

Explanation:

1+3/4=7/4

3/4=1 so 1:3/4 as x:7/4

= then cross multiply

(3/4)x=7/4

x=7/4(4/3)

x=7/3

Answer:

The President and American Capitalism since 1945 describes the many ways presidential actions have affected the development of capitalism in the post–World War II era. Contributors show how, since Harry S. Truman took office in 1945, the American “Consumer-in-Chief ” has exerted a decisive hand as well as behind-the-scenes influence on the national economy. And, by extension, on the everyday lives of Americans.

The Employment Act of 1946 expanded presidential responsibility to foster prosperity and grow the economy. However, the details and consequences of the president’s budget often remain obscured because of the budget’s size and complexity, perpetuating an illusion that presidents matter less than markets. Essays in this volume highlight the impact of presidential decisions on labor, gender discrimination, affirmative action, poverty, student loans, and retirement planning. They examine how a president can influence the credit card economy, the rebuilding of postindustrial cities, growth in the energy sector and the software industry, and even advances in genetic engineering. They also look at how economic gains in one particular area can have ramifications in other areas. National defense strategies have led to the privatization of weapons acquisition and the development of the modern research university to create a defensive brain trust among citizens. Policies aimed at supporting competitive American businesses—for example, in the biotech field—also affect the environment.

This book is an important contribution to the history of capitalism, articulating how the president—by supporting policies that promote business growth in all sectors—has helped domestic companies expand internationally and added to a global image of the United States that is deeply intertwined with its leading corporations.

Answer:

50% and 50%

Explanation:

The graph shows that when the mixture of seeds planted contained 25% species X (and therefore 75% species Y, to make 100%), 50% of the seeds harvested were species X. If 50% of the seeds harvested were species X, the other 50% of the seeds harvested must have been species Y.
