Is the triangle a right triangle? 4 6 7 Is this a right triangle?

Bingel [31]

Answer:

Step-by-step explanation:

Given :-

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.

Pythagoras Theorem :-

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 .

Sum of Squares of 4 and 6 :-

$:\implies$ 4² + 6²

$:\implies$ 24 + 36

$:\implies$ 60

Square of 7 :-

$:\implies$ 7²

$:\implies$ 49

And :-

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

Hence the triangle is not a right angle triangle.

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:

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
