Student researchers investigated whether balsa wood is less elastic after it has been immersed in water. They took 60 pieces of balsa wood and randomly assigned half to be immersed in water and the other half not to be. They measured the elasticity by seeing how far (in inches) the piece of wood would project a dime into the air.

​Does the p-value obtained using the theory-based method (p < 0.0001) agree with that obtained using the randomization/simulation-based method (p < 0.0001)?

Answers

Answer 1
i actually dont know this
Answer 2

Yes, they are quite similar. the p-value obtained using the theory-based method (p < 0.0001) agree with that obtained using the randomization/simulation - based method (p < 0.0001)

P- value is the probability of obtaining a value of test statistic more extreme in the direction of alternative hypothesis than the observed one. In easy words if p -value < level of significance we reject H0 in favor of H1.

Here:

p-value < 0.0001 => we reject H0.

If the statistical software renders a p value of 0.000 it means that the value is very low, with many "0" before any other digit.

So the interpretation would be that the results are significant, same as in the case of other values below the selected threshold for significance.

Therefore, yes they are quite similar.

Given :

Outcome 0 1 2 3 4 5 6 7 8 9

Number of Trials 4 2 5 3 2 6 6 3 6 3

The experimental probability of obtaining an odd number :

Odd outcomes are : 1, 3, 5, 7, 9

Total number of trials = Σ(4 2 5 3 2 6 6 3 6 3) = 40

Total number of odd outcomes = (2+3+6+3+3) = 17

If a rectangular prism has a length of 3 1/2 in and a width of 9 in and a height of 3 1/2, what would the surface area be?

Answers

The surface area is 150.5 in

Answer:

The surface area of this rectangular prism is 150.5 [tex]inches^{2}[/tex].

Step-by-step explanation:

The formula for finding the surface area of a rectangular prism is this :

A=2(wl + hl + hw)

l = 3.5, w = 9, h = 3.5

Now we substitute those values in and solve for A.

A = 2 · ( 9 · 3.5 + 3.5 · 3.5 + 3.5 ·9) = 150.5

The surface area of this rectangular prism is 150.5 [tex]inches^{2}[/tex].

x²-10xy + 16y²-z² + 6yz​

Answers

Answer:

(x - 8y + z)(x - 2y - z)

Step-by-step explanation:

Factorize :

x²-10xy + 16y²-z² + 6yz​

Solution:

x²-10xy + 16y²-z² + 6yz​

Firstly, make sure that all the terms are arranged in a well ordered manner:

x²-10xy + 16y²-z² + 6yz​

Secondly, split the term (16y²) common to both equation:

(x²-10xy + 25y²) - 9y² -z² + 6yz​

Thirdly, factorize both terms:

(x - 5y)² - 1(z² - 6yz + 9y²)

Factorizing the second term:

(x - 5y)² - (z - 3y)²

Using the difference of two squares, that is A² - B² = (A + B)(A - B):

(x - 5y)² - (z - 3y)² = [(x - 5y) + (z - 3y)][(x - 5y) - (z - 3y)]

= [x - 5y + z - 3y][x - 5y - z + 3y]

= (x - 8y + z)(x - 2y - z)

[tex]\frac{9\pi}{4} - 2\pi = \frac{9\pi}{4} - \frac{8\pi}{4} = \frac{\pi}{4}[/tex]

Thus, the sine and cosine are:

Given:

Leila is arranging 11 cans of food in a row on a shelf. She has 4 cans of corn, 1 can of peas, and 6 cans of beets.

To find:

The distinct orders can the cans be arranged if two cans of the same food are considered identical.

Solution:

Total number of cans = 11

Cans of corn = 4

Cans of Peas = 1

Cans of beets = 6

We need to find divide total possible arrangements (11!) by the repeating arrangements (1!, 4!, 6!) to find the distinct orders can the cans be arranged if two cans of the same food are considered identical.

[tex]\text{Distinct order}=\dfrac{11!}{1!4!6!}[/tex]

[tex]\text{Distinct order}=\dfrac{11\times 10\times 9\times 8\times 7\times 6!}{1\times (4\times 3\times 2\times 1)\times 6!}[/tex]

[tex]\text{Distinct order}=\dfrac{55440}{24}[/tex]

Mr. Ahmed sold his motorcycle to Mr. Saad at a loss of 28%. Mr.Saad spent Rs.1680 on its repairs and sold the motorcycle to Mr. Faiz for Rs.35910, thereby making a profit of 12.5%. Find the cost price of the motorcycle for Mr. Ahmed.

Answers

Answer:

Rs. 42000

Step-by-step explanation:

Let us assume that Mr. Ahmed bought the bicycle for Rs. x, and sold it for Rs. y to Mr. Saad. Since he made a loss of 28%, hence:

y = x - 0.28x = 0.72x

Mr. Saad spent Rs.1680 on its repairs, therefore the total cost price of the motorcycle = 0.72x + 1680

He then sold it for Rs.35910 making a profit of 12.5%. Therefore:

0.72x + 1680 + [0.125(0.72x + 1680)] = 35910

0.81x + 1890 = 35910

0.81x = 34020

x = Rs. 42000

Therefore the cost price of the motorcycle for Mr. Ahmed is Rs. 42000

On a given test with a maximum possible score of 100 points, the vast majority of the 259 students in a class scored either a perfect score or a zero, with only one student scoring within 10 points of the mean. Could we say that the test scores are normally distributed? Explain your answer.

Answers

Answer:

no, in a normal distribution mode=median=mean. So while in theory, the median and the mean can be the same, the mode is not.

Step-by-step explanation:

Based on the maximum possible score, the scores by the student, and the deviation, we cannot say that the test scores are normally distributed.

What makes a distribution normal?

In a normal distribution, the mean, mode and median have to be equal thanks to the bell-shaped nature of the distribution.

In this case, the median will be the score of the single student who is 10 points off the mean.

The mean will be affected by the extreme values of zero and a perfect score, and the mode will either be zero or 100.

The mean, mode, and median are therefore not the same so this isn't a normal distribution.

What is the distance between [(3 + 4i) + (2 - 3i)] and (9 - 2i)?

Answers

Answer:

5

Step-by-step explanation:

(3 + 4i) + (2 - 3i) = 3 + 4i + 2 - 3i = 5 + i

distance between (5 + i) and (9 - 2i) is the difference between them. and difference means subtraction.

(9 - 2i) - (5 + i) = 9 - 2i - 5 - i = 4 - 3i

and since we are looking for a distance, we are looking for the absolute value of that subtraction.

after all, we could have done the subtraction also in the other direction

(5 + i) - (9 - 2i) = -4 + 3i

and this must be the same distance.

|(-4 + 3i)| = |(4 - 3i)|

and that is done by calculating the distance of any of these 2 points from (0,0) on the coordinate grid of complex numbers.

|(a +bi)| = sqrt(a² + b²)

in our case here

distance = sqrt(4² + (-3)²) = sqrt(16 + 9) = sqrt(25) = 5

as you can easily see, this is (as expected) the same for the result of the subtraction in the other direction :

sqrt((-4)² + 3²) = sqrt(16+9) = sqrt(25) = 5
