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:

\frac{4250*100}{25000} = 17

The prevalence of flu for the past year, as indicated from the survey participants, was of 17%.

A car travels 87 miles north and 114 miles west. what is the magnitude of the cars resultant vector
anyanavicka [17]

The magnitude of the resultant vector is 27 miles

<h3>How to determine the vector magnitude</h3>

Resultant vector = Distance of A - Distance of B

This is so because of the opposite direction of the car's movement

A = 87 miles

B = 114 miles

Resultant vector = 114 - 87

Resultant vector = 27 miles

Thus, the magnitude of the resultant vector is 27 miles
