What’s the surface area in square units if right I’ll mark brainleiest

Answers

Answer: 349 square units

============================================

Work Shown:

L = 5.5 = lengthW = 5 = widthH = 14 = height

SA = surface area of rectangular prism

SA = 2*(L*W + L*H + W*H)

SA = 2*(5.5*5 + 5.5*14 + 5*14)

SA = 2*(27.5 + 77 + 70)

SA = 2*(174.5)

SA = 349

The surface area is 349 square units.

A researcher wants to determine if college students typically drink more than 3 times per week. She collects data on 125 college students. From the sample, she finds that they drank an average of 3.5 times per week, with a standard deviation of 2.3 drinks. Use a 5% significance level for any testing. Based on the scenario above, which of the following is TRUE regarding the type of test that would need to be performed?

a. It is a two-tailed test.
b. It must be completed using the critical value approach.
c. It is a one-tailed test.
d. We reject the null and prove our claim.
e. We would need to estimate the significance level from the data.
f. Hypothesis testing cannot be performed on percentages.

Answers

Answer:

C: It is a one-tailed test.

Step-by-step explanation:

We are told the researcher wants to determine if college students typically drink more than 3 times per week.

This means the null hypothesis is;

H0: μ ≥ 3

this indicates that it's a one tailed test as the null hypothesis is only to the right side of 3 and thus just one tail.

This question will be solved using p-value approach since we are given population mean, sample mean, sample size and standard deviation.

We can't reject the null without finding out the p-value and seeing if it is less than the significance value given.

Hypothesis testing can be done done proportions or percentages.

Thus, the correct option is one-tailed test.

A game decreased in price by 1/6
After the reduction it was priced at £75.
What was the original price of the game?

Answers

Imagine you didn’t know what it was priced after the reduction. Use “y” as the original number since we don’t know: y times (1-1/6) = 75
it is 1 minus 1 over 6 since you aren’t finding the price after reduction. Your finding the original one which means you need to minus by one (6 over 6= 1) so u would do 1 - 1/6
So if you do it the other way round it would be 75 divided by 1 minus 1 over 6
Which gives us 90!!

The median is 6

Step-by-step explanation:

First put the numbers in order: 3,4,4,4,5,7,7,8,9,12

Here, the 5th & 6th terms are 5 &7

So, median = 5+7/2

=12/2

Answer:

Step-by-step explanation:

For funding out the median firstly we need to arrange the data in ascending or descending order . Here on arranging the given data in ascending order we have ,

3,4,4,4,5,7,7,8,9,12

The median is the middle most observation , in case of odd nos . And the mean of two middlemost observations in case of even nos . Here the number of data is even , and the two middlemost observations are 5 and 7 , so ,

=> Median = x₁ + x₂ / 2

=> Median = 5 + 7/2

=> Median = 12/2

=> Median = 6

Hence the median of the given data is 6 .

None of the above.

Answers

Answer:

Fails the true premises test and fails the proper form test

Explanation:

A valid argument must pass the true premises test and the proper form test.

True premises test checks to see if what the premises is saying is true about the world, example- pigs do not have wings and so the argument fails the true premises test. Proper form test assumes the premises is true and then checks to see if a valid conclusion was drawn based on the premises(even though it might fail the true premises test and may not be true about the world)
