Using it's concept, it is found that the prevalence of frequent multivitamin use is of 0.4523 = 45.23%.
<h3>What is the prevalence of a sample?</h3>
The prevalence of a sample is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, 588 out of 1300 women reported taking a multivitamin at least 4 times a week during the month before pregnant, hence the prevalence is given by:
p = 588/1300 = 0.4523 = 45.23%.

You can state the qurstion in an other way
how many integers between 1-100 has 3 in their prime compostion or how many many numbers can be written as 3*a where a is any number
the multiplication table of 3 shows that 3*33=99
which means that highest product below 100 is 3*33
so there are 33 numbers that are divisible by three
Let P(x,y) be a point on the parabola. The definition of a parabola is the squared distance from P to focus F(2,2) equals the squared distance to the directrix x=8.
squared distance from P(x,y) to focus F(2,2)
(x - 2)² + (y - 2)²
squared distance from P(x,y) to the directrix x=8.
(x-8)²
Those are equal in a parabola,
(x - 2)² + (y - 2)² = (x-8)²
x² - 4x + 4 + y² - 4y + 4 = x² - 16x + 64
y² - 4y - 46 = -12x
That's a sideways parabola,
x = -(y² - 4y - 46)/12
The slope of the first line is
.
To be perpendicular the slope of the second line must be the negative reciprocal of the first:
Use the slope-intercept formula:
Substitute known values:
