8. In a word game, you choose a tile from a bag, replace it, and then choose another. If there are 28 vowels and 12 consonants,
sasho [114]

Answer:

The probability that you will choose a consonant and then a vowel is 0.21....

Step-by-step explanation:

Total no of tiles = 28 + 12 = 40

First you should choose a consonant = 12/40

Second you should choose a vowel = 28/40

So the probability you choose a consonant and then a vowel:

= 12/40 * 28/40

=336/1600

=0.21

So the probability that you will choose a consonant and then a vowel is 0.21....

Please help ASAP it is due today
Dmitrij [34]

Answer:

Step-by-step explanation:

What we know

total sum of angles = 540 deg

3/2 b cam also be written as 1.5b degrees.

So 1.5b + (b+45) + (2b - 90) +90 = 540

Step 1 -- get rid of parenthesis

         1.5b + b + 45 +2b -90 +90 =540

Step 2 -- combine the like expressions

         4.5b + 45 = 540

Step 3 -- subtract 45 from both the sides

         4.5b = 495

Step 4 -- divide 4.5 from both the sides

         b = 110  ----- not the right answer

Thats not right okay im sorry

but i guess if it is not 110 it should be 100, 90 etc.

90 = b is correct
