Answer: 30 minutes

Step-by-step explanation: First we can reduce the fraction 2/4 by dividing the numerator and the denominator by the greatest common factor of 2 and 4.

Since the factors of 2 are 1 and 2 and the factors of 4 are 1, 2, and 4, the greatest common factor of 2 and 4 is 2. So we divide the numerator and the denominator of 2/4 by 2 and we get the equivalent fraction 1/2.

Now we can change the question to say <em>1/2 of an hour is how many minutes?</em>

We know that 1 hour is equivalent to 60 minutes so half of 1 hour would be 30 minutes.

Therefore, 2/4 of an hour is 30 minutes.

Is the function given by, f(x)={3x-2 if x≤3 , 10-x if x&gt;3} continuous at x = 3?
Darya [45]
<h2>Answer:</h2>

yes

<h3>Step-by-step explanation:</h3>

This is a piecewise-defined function because it is defined by two or more equations over a specified domain is. The graph of this function is shown below. So this functions is continuous because its graph is a single unbroken curve. So the function is defined be the line 3x - 2 when x = 3 and the output here is y = 7

Check if given set of numbers 6,8,10 forms pythagorean triplet or not?​
kipiarov [429]

\LARGE{ \underline{ \tt{Required \: answer:}}}

We know that,

  • Pythagoras theoram is given by : p² + b² = h²

  • In a Pythagoras triplet, the longest side represents the hypotenuse of the triangle.

Then,

We should check that, whether the sum of squares of the smaller sides will be equal to the square of the third side or not. Then, we can determine the above easily.

Sum of squares of smaller sides:

= 6² + 8²

= 36 + 64

= 100

Square of longer side:

= 10²

= 100

Sum of squares of smaller sides = Square of longer side. Hence, 6,8,10 are Pythagorean triplets.

And we are done! :D

Drag each tile to the correct box. A data set that consists of many values can be summarized using the five-number summary. Arra
dimaraw [331]

Answer:

Minimum < Q1 < Median < Q3< Maximum

Step-by-step explanation:

Given

Minimum, Median, Maximum, Q3 and Q1

<em>See attachment for complete question</em>

Required

Order from least to greatest

In a dataset, the range is:

Range = Maximum - Minimum

This implies that, the minimum is the least and the maximum is the highest of the dataset

So, we have:

Minimum <         <              <           < Maximum

The median is the middle item; So, the above becomes

Minimum <         < Median <           < Maximum

In a dataset, the IQR is:

IQR = Q_3 - Q_1

This implies that:

Q_3 > Q_1

So, we have:

Minimum < Q1 < Median < Q3< Maximum

Mars2501 [29]

Answer:

Step-by-step explanation:

That means that the given expressions are equal.

100 - 2.5x = 100 + 2.5(5 - x)

100 - 2.5x = 100 + 12.5 - 2.5x

There is no solution to this.
