Answer:
Step-by-step explanation:
The radius of a circle is independent of the location of its center, and circles are always similar. Here, therefore, the circles are similar; their shapes are exactly the same. Only the radii differ from one another. The radius of Circle A is 3 and that of Circle B is 9; thus the radii differ by a factor of 3.
The solutions to the given quadratic equation are as follows:
x = 1.10, x = 10.9.
<h3>What is a quadratic function?</h3>
A quadratic function is given according to the following rule:
The solutions are:
In which:
For this problem, the equation in item D is:
-x² + 12x - 12 = 0
x² - 12x + 12 = 0
Hence the coefficients are:
a = 1, b = -12, c = 12.
Then the solutions to the equation are found as follows:
- Delta = (-12)² - 4 x 1 x 12 = 96
- x1 = 0.5(12 + sqrt(96)) = 10.9
- x2 = 0.5(12 - sqrt(96)) = 1.10
The solutions are:
x = 1.10, x = 10.9.

Answer:
Systematic Sampling
Step-by-step explanation:
Systematic sampling is one of the types of probability sampling method. It is an advanced form of simple random sampling. In this form, from the population of members, sample members are selected randomly. In this random selection, a starting point is fixed. The sample is created when the members are selected from the fixed intervals.
In the given excerpt, systematic sampling method has been used. Here, the sample has been created by selecting every third listed phone member. The interval has been created between in the sample size.
Answer:
C) 6/8+3/4
Step-by-step explanation:
1 16/32 = 1.5
6/8 = 0.75
3/4 = 0.75
0.75+0.75 = 1.5
