Answer:

42 times.

Step-by-step explanation:

The number of total alphabet = 26 tiles

The number of vowels = 5

The number of consonant = 26 - 5 = 21

Sofia will randomly select 1 tile from the bag and without replacement select another tile from the bag.

The probability to select consonant at first time = 21/26

Total tiles after the first selection = 26 - 1 = 25

The probability to select vowels at second time = 5/25

The probability to select consonant and vowels = \frac{21}{26} *\frac{5}{25} =\frac{21}{130}

Sofia will draw two tiles from the bag 260 times.

The prediction for the number of times Sofia will select a consonant tile and a vowel tile = \frac{21}{130} *260=42 \ times

Michael pays his cell phone service provider $49.95 per month for 500 minutes. Any additional minutes used cost $0.15 each. In J
arsen [322]

y = total cost used.

x = additional minutes

y = $49.95 + $0.15x

$61.20 = $49.95 + $0.15x. Subtract the $49.95 from each side.

$11.25 = $0.15x. Divide each side by $0.15

75 = x.

Michael used 75 additional minutes.

What is the greatest common factor of 40 and 27?
Olenka [21]

To find the greatest common factor of 40 and 27, we can first start by making a list of factors for each number.

The factors of 27 are: 1, 3, 9, 27

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

When looking at these numbers, we can see that 1 is the greatest common factor of both 40 and 27.
