The relative frequency for the class with lower class limit 31 is 8.57%.

<h3>How to calculate the frequency?</h3>

It should be noted that the lowrr class frequency is 31 in this case.

Therefore, the relative frequency for the class with lower class limit 31 will be:

= 3/(6+4+4+9+3+9) × 100

= 3/35 × 100

= 8.57%

Therefore, the relative frequency for the class with lower class limit 31 is 8.57%.

Answer:

  it has 10 times the value

Step-by-step explanation:

In a base-10 number system, each digit to the left has a value 10 times the one to its right.

  3 in the thousands place has a value of 3000

  3 in the hundreds place has a value of 300

The digits values are related by a factor of 3000/300 = 10. The digit in the thousands place has 10 times the value of the digit in the hundreds place.

Problem Set
Artemon [7]

Answer:

3 < x < 13

Step-by-step explanation:

<u>Triangle Inequality Theorem</u>

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Let x be the length of the unknown side.

Therefore, x will either be the longest side or one of the shorter sides.

Therefore:

   x < 5 + 8

⇒ x < 13

And:

   8 < 5 + x

⇒ 3 < x

So the range of possible values of the third side is <u>greater than 3</u> and <u>less than 13</u>:   3 < x < 13
