It depends on how many sides it has
If it has 2 then 50 percent
If it has 4 then 25 percent
If it has 5 then 20 percent
You divide the amount of sides by 100
x / 100 = percent
Example 2 / 100 = 50.

Answer:
x = -1, y = -4
Step-by-step explanation:
Let's solve our system of equations by substitution.
y = 5x + 9y = −x + 3
Step: Solve = 5x + 9 for y:
y = 5x + 9
Step: Substitute 5x + 9 for y in y = −x + 3:
y = −x + 3
5x + 9 = −x + 3
5x + 9 + x = −x + 3 + x (Add x to both sides)
6x + 9 = 3
6x + 9 + −9 = 3 + −9 (Add -9 to both sides)
6x = −6
6x/ 6 = −6/6(Divide both sides by 6)
x = −1
Step: Substitute −1 for x in y = 5x + 9:
y = 5x + 9
y = (5)(−1) + 9
y = 4(Simplify both sides of the equation)
So our answers are y = -4 and x = -1.
Answer:
The probability that all the six people will test negative for the antibody is 0.9472.
The probability that the test comes back positive for at least one of the six people is 0.0528
Step-by-step explanation:
Consider the provided information.
probability that antibody is present will be effective is 99.1% and not present is 99.1% of the time.
Part (A)What is the probability that the test comes back negative for all six people?
Let P(X)= P(Antibody not present)
We want test comes back negative for all six that means antibody is present for all six. Thus X=0
The probability that all the six people will test negative for the antibody is 0.9472.
Part (B) What is the probability that the test comes back positive for at least one of the six people?
Hence, the probability that the test comes back positive for at least one of the six people is 0.0528
That question mark is filled in with the y-intercept. The y-intercept is where the graph goes through the y-axis. Our graph goes through the y-axis at 1, so the equation is y = 4x + 1
Answer:
A to B for y: -6
A to B for x: 2
Step-by-step explanation:
to figure out y, you subtract the first “y” from the second “y”
0-6= -6
to figure out x, you subtract the first “x” from the second “x”
3-1=2
