ANSWER
EXPLANATION
The boundary line passes through (-2,2) and (0,-2).
The slope of this line is
The y-intercept is , c=-2.
The slope-intercept form of this line is given by;
We substitute values to obtain;
Since the lower half-plane is shaded the required inequality is
Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 12² = 13², so
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x = = 5
Both the sample can be used to make inferences about the population.
The correct option is D.
Given
Jason and Yolanda both drew a simple random sample from a non-normally distributed population of 25,000.
Jason’s sample consisted of 0.24% of the population, while Yolanda’s sample consisted of 0.32% of the population.
<h3>Percentage;</h3>A percentage is a number or ratio that can be expressed as a fraction of 100.
According to the question
Total number of population = 25000
Percent of a sample of Jason = 0.24%
Percent of the sample of Yolanda's = 0.32%
So, the number of the population according to Jason's sample is given by;
The number of the population according to Yolanda's sample is given by;
Hence, Both the sample can be used to make inferences about the population
