Answer:
Step-by-step explanation:
The probability will be number of Yellows divided by the total number of Marbles
Here there are 3 yellows and 11 marbles in total
The probability is
3/11
Don't mention it
The given equation is (1/2)a + (2/3) b = 50
and b = 30
Substituting the given value of b is above the equation we get
Therefore, a = 60 and b = 30 is a solution of the given equation.

<h3>
Z score</h3>
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where x is the raw score, μ is the mean and σ is the standard deviation.
Given that μ = 12.01, σ = 0.89, hence:
For x = 10.98:
z = (10.98 - 12.01)/0.89 = -1.16
The associated z score for filling to 10.98 oz. is -1.16.

Answer:
(4+7i)(4-7i).
This is because you FOIL it to get:
16 + 28i - 28i -49i^2.
That equals to 16 - 49i^2, which equals to:
16 + 49
65, which is a real number.
