Much as you would like it to be D, it isn't. D has its center at (3,4). You must change the sign on both numbers inside the brackets.
You need something that looks like (x + 3)^2 + (y + 4)^2. So it could be A or B. How do you know which? The graph should give you an answer, then we'll talk about it. The red circle is A the blue circle is B. Which one is correct?
The answer to that is that the center is 5 units away from the origin. The radius of this circle is the sqrt(25) = 5 units away from the center. The blue one has a radius of sqrt(5) which is something over 2. It is not enough. So what's the answer?
Answer:
The z value is - 2.88
Step-by-step explanation:
The formula of the z-score of a population is z = (x¯ - μ)/(σ/)
The given in the problem is:
- μ = 121
- σ = 21
- x¯ = 112.35
- n = 49
Let us substitute all of these values in the rule above
Simplify up and down
z = - 2.883333
Round it to 2 decimal places
∴ z = - 2.88
The z value is - 2.88
Answer: The dimensions of rectangle are 32 feet and 16 feet.
Step-by-step explanation:
Let the width of rectangle be 'x'.
Let the length of rectangle be '2x'.
Perimeter of fence = 96 feet
As we know the formula for "Perimeter":
Hence, the length of rectangle is 2x=2×16 = 32 feet and width is 16 feet.
Therefore, the dimensions of rectangle are 32 feet and 16 feet.
