Answer:
The slope of the line y = 3x - 1 is 3 , y intercept is -1
The slope of the line y = -6x - 10 is - 6 and y intercept is -10
Step-by-step explanation:
y = mx + b where m = slope and b = y intercept
So
The slope of the line y = 3x - 1 is 3 , y intercept is -1
The slope of the line y = -6x - 10 is - 6 and y intercept is -10
The answer is c.) 2%. Since the question is talking about false negatives, meaning the chance that the results are false, then we take a look at the 98% which represents the chance of giving an accurate result for the people who are not infected meaning for those who are positive. Thus, the answer is 2% because this is the remaining percentage if 100-98%.
Answer:
Stratified sampling
Step-by-step explanation:
The is a type of sampling in which the population of interest is divided into subpopulations and then each subpopulation is randomly sampled.
In this case study, instead of just doing a random sampling of all students, the research divided the population of all students into subpopulations which includes freshmen, sophomores, juniors and seniors and then she makes a random sampling of each of these subpopulations.
Answer:
$7,359.65
Step-by-step explanation:
The computation of the amount that to be deposited is shown below:
Here we have to calculate the present value
As we know that
Present value = future value ÷(1+ rate of interest)^years
where,
rate of interest = 12.2% ÷ 4 = 3.05%
And, the years is = 5 × 4 = 20
Now the present value is
= $13,422 ÷ (1+ 3.05%)^20
= $7,359.65
