which of the following can be a Pythagorean triplets?:
a) 2cm 2cm ,4cm b) 5cm, 12cm ,13cm c) 3cm ,5cm ,6cm d) 7cm, 4cm 5 cm.
need full solution
or I'll report
As we know that,
Pythagoras triplet
1) a² + b² = c²
Let
[tex]\sf \: {2}^{2} + {2}^{2} = {4}^{2}[/tex]
[tex]\sf \: 4 + 4 = 16[/tex]
8 ≠ 16Hence, A can't be Pythagoras triplet2) a² + b² = c²
[tex]\sf \:5 {}^{2} + {12}^{2} = {13}^{2}[/tex]
[tex]\sf \: 25 + 144 = 169[/tex]
169 = 169Therefore, B can be Pythagoras triplet3)a² + b² = c²
[tex]\sf {3}^{2} + {5}^{2} = {6}^{2}[/tex]
[tex]\sf 9 + 25 = 36[/tex]
34 ≠ 36Hence, C can't be Pythagoras triplet4) a² + b² = c²
[tex]\sf {5}^{2} + {4}^{2} = {7}^{2}[/tex]
[tex]\sf \: 25 + 16 = 49[/tex]
41 ≠ 49Hence, D can't be Pythagoras tripletTherefore :-Only B can be Pythagoras triplet.

A study of the career paths of hotel general managers sent questionnaires to an SRS of 160 hotels belonging to major U.S. hotel chains. There were 114 responses. The average time these 114 general managers had spent with their current company was 11.78 years. Give a 99%; confidence interval for the mean number of years general managers of major-chain hotels have spent with their current company. (Take it as known that the standard deviation of time with the company for all general managers is 3.2 years.)
Answer:
The 99% confidence interval for the mean number of years general managers of major-chain hotels have spent with their current company is between 11.01 years and 12.55 years.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.99}{2} = 0.005[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.005 = 0.995[/tex], so [tex]z = 2.575[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 2.575*\frac{3.2}{\sqrt{114}} = 0.77[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 11.78 - 0.77 = 11.01 years
The upper end of the interval is the sample mean added to M. So it is 11.78 + 0.77 = 12.55 years
The 99% confidence interval for the mean number of years general managers of major-chain hotels have spent with their current company is between 11.01 years and 12.55 years.
Find the point-slope equation of the line using the point (3, 5) and slope 3/2
Answer:
y=3/2x+5
Step-by-step explanation:
so the points are 3,5 and y=mx+b is point slope form.
y = m which is slope and b is y int. so it turns out to be y=3/2x+5.

Given:
The given table represents the ingredient need to make 4 muffins.
To find:
The amount of flour needed to make 12 muffins.
Solution:
We have, the data for 4 muffins.
From the given table it is clear that,
Flour need for 4 muffins = 250 g
Flour need for 1 muffins = [tex]\dfrac{250}{4}[/tex] g
Flour need for 12 muffins = [tex]\dfrac{250}{4}\times 12[/tex] g
= [tex]250\times 3[/tex] g
= [tex]750[/tex] g
So, 750 g flour is need to make 12 muffins.
Therefore, the correct option is D.
Answer: 750
Step-by-step explanation: If The recipe for four muffins calls for 250g of flour if you multiply 250 by 3 get the answer wich is 750

The roof top would be 0. At 12 seconds the ball is at -225.6, which would be the ground so the building would be 225.6 meters tall.

Shana wants to use all 62 feet of the fencing she has to make a rectangular run for her dog. She decides to make the length of the run 20 feet. She writes and solves the equation 2 l plus 2 w equals 62 to find the width of the run.
Which statements are true of the solution? Check all that apply.
The value of w is 10 feet.
The value of w can be zero.
The value of w cannot be a negative number.
Substitution is used to replace the variable l with a value of 20.
The subtraction property of equality is used to isolate the term with the variable w.
Answer:
The answers you guys are looking for are C, D, and E
Step-by-step explanation:
I dont have one. :)
The true statements include
(c) The value of w cannot be a negative number.(d) Substitution is used to replace the variable l with a value of 20.(e) The subtraction property of equality is used to isolate the term with the variable w.How to determine the true statements?The equation is given as:
2l + 2w = 62
Where:
l = 20
Substitute l = 20
2 * 20 + 2w = 62
Evaluate
40 + 2w = 62
Subtract 40 from both sides
2w = 22
Divide both sides by 2
w = 11
The above computation means that the true statements include (c), (d) and (e)

IMAX Movie Prices. There were 322 people at a recent showing of the IMAX 3D movie "300". Admission was $8.75 each for adults and $6.00 each for children. Receipts totaled $2531.50. How many adults and how many children attended?
Answer:
218 adults and 104 children attended.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=322 (1)
8.75x+6y=2531.50 (2), where:
x is the number of adults
y is the number of children
First, you can solve for x in (1):
x=322-y (3)
Then, you can replace (3) in (2) and solve for y:
8.75(322-y)+6y=2531.50
2817.5-8.75y+6y=2531.50
2817.5-2531.50=8.75y-6y
286=2.75y
y=286/2.75
y=104
Finally, you can replace the value of y in (3) to find x:
x=322-104
x=218
According to this, the answer is that 218 adults and 104 children attended.
