Step-by-step explanation:
For this question, your friend is the point-slope form.
Point-slope form =
The only variables you replace are m = slope, y1 = y of a given point, and x1 = x of a given point.
First, we need to find the slope that is perpendicular to the equation
An equation that is perpendicular to another equation have to be negative reciprocals (negative inverse) of each other.
If the slope is 3, then the negative reciprocal of 3 is .
So, since the given slope is -3/4, the negative reciprocal is .
We will use the negative reciprocal as m since we are trying to find the equation of line that includes (-3, -3) and is perpendicular to the other equation.
We will use point slope form using the (-3, -3) points and negative reciprocal as m.
Now, we need to convert this into slope-intercept form. The reason why we need to do this is because y = mx + b, where b is the y-intercept. To do this, solve for y - or in other words, isolate y..
The y-intercept of the line is 1.
Answer:
The prevalence of flu for the past year, as indicated from the survey participants, was of 17%.
Step-by-step explanation:
Given the survey, the prevalence of the flu, as a percentage, is given by:
Number of individuals diagnosed with flu, multiplied by 100, and divided by the size of the sample.
In this question, we have that:
Sample of 25,000, and 4,250 of those had been diagnosed with the flu at some point in the past year. So, the prevalence of the flu is given by:
The prevalence of flu for the past year, as indicated from the survey participants, was of 17%.
