Answer:
Option C.
Step-by-step explanation:
If a vertical line intersects the x-axis at point (c,0), then the equation of line is x=c.
From the given figure it is clear that it is a vertical line and it intersects the x-axis at (-1,0). There are infinite values of y at x=-1.
So, the equation of given line is
Therefore, the correct option is C.

Answer:
No
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they can tell the difference between Coke and pepsi, or they cannot. The probability that a person has o telling the difference between Coke and pepsi is independent from each other. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to the normal distribution if

and

In this problem, we have that:

First condition




Second condition




Multiplying by -1


p cannot be at the at the same time greather than 2/3 and lesser than 1/3. So we cannot assume that the sampling distribution of the proportion of people that correctly chose Pepsi is normal.
Answer:
The length of one side of the square is 3.
Step-by-step explanation:
The perimeter of any given shape is all of the sides added together. So, the perimeter of the triangle is 5x + 4x + 3x. Added together, 12x.
The perimeter of the square is (x + 2)*4. Distributed, it's 4x + 8. Since we know they're equal, set it up like this:
12x = 4x + 8
You then find that x = 1. Plug that into one side of the square, x + 2, to get 3.
Hello!
The degrees in a circle add to 360°
Since WZ is a diameter the angles on one side of the line add to 180°
We know that the angles to the right of WZ add to 180 and the angle of XW is 63.
We add these to get ZWX
180 + 63 = 243
The answer is 243°
Hope this helps!
