Is the triangle a right triangle?<br> 4 6 7<br> Is this a right triangle?
Bingel [31]

Answer:

No

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

  • A triangle with some side measure .
  • The sides are 4 ,6,7.

And we need to tell whether it is a right angled triangle or not . It will be a right angled triangle if it follows the Pythagoras Theorem.

<u>Pythagoras</u><u> Theorem</u><u> </u><u>:</u><u>-</u><u> </u>

  • In right angle triangle the sum of squares of the two smallest sides is equal to the square of the largest side .

Here the two smallest sides are 4 & 6 .

<u>Sum </u><u>of </u><u>Squares </u><u>of </u><u>4</u><u> </u><u>and </u><u>6</u><u> </u><u>:</u><u>-</u><u> </u>

:\implies 4² + 6²

:\implies 24 + 36

:\implies 60

<u>Square</u><u> </u><u>of </u><u>7</u><u> </u><u>:</u><u>-</u><u> </u>

:\implies 7²

:\implies 49

<u>And </u><u>:</u><u>-</u><u> </u>

  • They aren't equal. So the triangle is not a right angled triangle .

<u>Hence </u><u>the triangle is not a right angle triangle</u><u>.</u>

For a population with a mean of 45 and standard version of 10, what is the standard error of the dustribution of sample means fo
Luden [163]

Answer:

5

Step-by-step explanation:

The formula for Standard Error =

Standard deviation /√n

Where

n = Random number of samples

From the above question,

Standard deviation = 10

n = 4

Hence, Standard Error is calculated as:

= 10/√4

= 10/2

= 5

Therefore, the Standard error = 5
