Answer:
Option d.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
79 percent of adults age 18 years and older in the United States use the Internet.
This means that 
98% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
Which of the following should be used to find the sample size (n) needed?
We have to find n for which 
So the equation is:
Option d.
Answer:
Move right 6 units and up 4 units
Step-by-step explanation:
Quadratic Equation: f(x) = a(bx - h)² + k
<em>a</em> = vertical stretch/shrink
<em>b</em> = horizontal stretch/shrink
<em>h</em> = horizontal movement left/right
<em>k</em> = vertical movement up/down
Slope (m) = y2-y1 / x2-x1
m = 7 - 4 / 0 + 5
m = 3 / 5
In short, Your Answer would be 3/5
Hope this helps!
The function is Count.
There are many functions available on a database to do aggregated calculations. So they can be referred as aggregate functions. The aggregate functions available are:
- count: To get the the number of rows with a specified criteria.
- sum: To get the sum of values on the selected cells.
- max: To get the maximum value within a selected range of data.
- min: To get the minimum value within a selected range of data.
- avg: To get the average of the selected data.
As the field name referred here is 'lastname', the appropriate aggregate function would be count.
