<u>Answer:</u>

5.65 cm

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

We are given that the length of each leg of an isosceles right triangle is 4 cm and we are to find the length of the hypotenuse.

For this, we will use the Pythagoras Theorem:

a ^ 2 = b ^ 2 + c ^ 2

where a is the hypotenuse.

a ^ 2 = 4 ^ 2 + 4 ^ 2

\sqrt { a ^ 2} = \sqrt { 3 2 }

a = 5 . 6 5

Therefore, the length of the hypotenuse is 5.65 cm.

Answer:

hypotenuse = 4√2

Step-by-step explanation:

It is given that, the  length of each leg of an isosceles right triangle is 4 cm

<u>To find the hypotenuse</u>

From the given information we get the given triangle is a right triangle with angles 45°, 45° and 90°

Therefore the side are in the ration 1 : 1 : √2

Here two legs are give

leg1 : leg2 : hypotenuse = 4 : 4 : 4√2

Therefore hypotenuse = 4√2

Finger [1]

Using it's concept, it is found that there is a 0.183 = 18.3% probability that the person has completed a bachelor's degree and no more.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Researching this problem on the internet, it is found that 529 + 1054 = 1583 out of 1911 + 6730 = 8641 people aged 40 or older have completed a bachelor's degree and no more, hence the probability is given by:

p = 1583/8641 = 0.183.
