What is the approximate height of the hat?

2.93 centimeters, because height = square root of the difference of 16 and 7.4
4.84 centimeters, because height = square root of the sum of 16 and 7.4
17.63 centimeters, because height = square root of the sum of the squares of 16 and 7.4
14.19 centimeters, because height = square root of the difference of squares of 16 and 7.4

Option D.

Step-by-step explanation:

Pythagoras theorem says in a right angle triangle,

Hypotenuse² = Base² + height²

In this question given dimensions of the triangle are

Hypotenuse = 16 cm

and base = 7.4

Now from the formula

(16)² = (7.4)² + Height²

Height² = (16)² - (7.4)²

Height² = 256 - 54.76

Height = √(201.24)

           = 14.19 cm

Therefore, Option D. will be the answer.

step-by-step explanation:

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
