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 = 
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 =

Step-by-step explanation:
confidence interval using a two sample t test between percents This can be used to compare percentages drawn from two independent samples in this case employees. It is used to compare two sub groups from a single sample example the population on the planet
Without the instructions, I can only assume that you are to "expand the given expression."
Following order of operations rules requires that (3x-2)^2 and -6(2x-1.5) be evaluated first.
(3x-2)^2 = 9x^2 - 12x + 4 and -6(2x-1.5) = -12x + 9
Then we have 9x^2 - (9x^2 - 12x + 4) -12x + 9
the 9x^2 terms cancel, leaving us with 12x - 4 - 12x + 9 = 5 (answer)
Hello!
To solve an algebraic equation, you must isolate the variable on one side. We’ll begin by restating the given equation:
12 + 12n = -48
Now subtract 12 from both sides of the equation:
12n = -60
Divide both sides by 12:
n = -5
We have now proven that “n” is equal to (-5).
I hope this helps!
