The letter tiles shown below are in a bag. Without looking I am going to draw one tile
Nitella [24]

The probability of writing a vowel is 0.5 (option b)

<h3>How to calculate the probability in this situation?</h3>

Probability is a way of measuring the certainty of occurrence of a specific event. Probability is measured from 1 to 0, with numbers closer to 1 referring to a higher chance and numbers closer to 0 referring to a lower chance.

According to the above, to calculate the probability we must perform the following operations:

  • Calculate how many vowels and how many consonants are there in total? In the series of letters there are 3 vowels and 3 consonants.
  • Later, we divide the number of vowels by the total number of letters to find the probability.

  • 3 vowels ÷ 6 letters = 0.5 odds

Note: This question is incomplete because some information is missing. Here is the complete information

  • The letter tiles shown below are in a bag. Without looking I am going to draw one tile. What are my chances of drawing a vowel?
  • O,I,S,P,L,A

A.0.3

b.0.5

C.3

D.0.05

Find the missing lengths:<br> LO=5 and OK=4, find OH and KH.
hodyreva [135]

Answer:

The length of KH is 6 units and OH is 6.3 units.

Step-by-step explanation:

Given the figure with lengths LO=5 and OK=4. we have to find the length of  OH and KH.

In ΔLOH

By Pythagoras theorem

LH^2=LO^2+OH^2\\\\LH^2=5^2+OH^2 → (1)

In ΔKOH,

KH^2=OH^2+OK^2\\\\KH^2=OH^2+4^2  → (2)

In ΔKHL,

KL^2=LH^2+KH^2

Using eq (1) and (2), we get

KL^2=5^2+OH^2+OH^2+4^2

9^2=25+2OH^2+16

⇒ 2OH^2=81-25-16=40

⇒ OH=\sqrt{20}=6.324\sim6.3units.

Put the above value in eq 2, we get

KH^2=20+4^2=36

⇒ KH=6 units.
