3. The equation 4x + 16y = 36 is a true equation for a particular
1 answer:
Answer:
See below.
Step-by-step explanation:
We know that the equation is a true equation for a particular value of x.
Now, let's see what happens if we divide everything by 4. In other words:
Divide:
So, we get .
When we divided everything by 4, we used the division property of equality. Under this property, the equation remains the same even if we divided since we did the <em>same thing to both sides of the equation. </em>
Therefore, is also true for the same value of x because it is just a simplified version of
.

the 12 in the numerator (top) and the 12 in the denominator (bottom) cross out so you are left with 50.
Answer: 50
Let's first denote:
F - a favorable response
F' - an unfavorable response
S - successful
We know that:
So, from the conditional probability, we can calculate:
