(HELP ASAP) A bag contains lettered tiles. The theoretical probability of choosing a vowel is 30%. The bag contains 42 consonants. How many tiles are in the bag?

I'm not so sure but my answer is 54 or 55

Step-by-step explanation:

The probability of choosing a vowel is 30%, and there are 42 consonants, so we would set up an equation like this:

42 times 30% (0.30) = 12.6 (rounded to 12)

So we have 12 vowel and 42 consonants in the bag, the total tiles would be:

12+42= 54

* But in case your teacher rounded up to 13 (vowels), the answer should be 55. But the probability rounded up to 13 is very low.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
