Answer:
Step-by-step explanation:
Total number of people, n = 30
number of white people = 17
number of non white people = 13
number of selected person which are white = 12
So, the number of ways to select the 12 white people out of 17 white people
=
the number of ways to select 12 white people out of total 30 people
So, the probability to select 12 white people out of 30 people is
9/10 = z/8
cross multiply
9/10(10)(8) = z/8(8)(10)
9(8) = z(10)
72 = 10z
Isolate the z, divide 10 from both sides
72/10 = 10z/10
z = 72/10
z = 7.2
7.2, or D) is your answer
hope this helps
Answer:
-3 x 1 ??
Step-by-step explanation:
y is where line x and line y meet (i think ??). They want y - 3. y is vertical, and negative is down from the x-y intersection. So go down 3 spots to -3. ??
Go to the x-y intersection again. This time they want 1/2 (x + 2). So at positive 2 on the x line. 1/2 of that is at positive 1 on the x line.
??
Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.
