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%.

Answer:
Q = 3
Step-by-step explanation:
3 * P + 7 * Q + 15 * R = 102
7Q = 102 - 3P - 15R
Q = (102 - 3P - 15R)/7
Try P = 2; R = 3
Q = 51/7 not an integer
Try P = 2; R = 5
Q = 21/7 = 3
Solution: P = 2; Q = 3; R = 5
Answer: Q = 3
Answer:
The lower quartile of Class A is greater than the lower quartile of Class B.
Class A has a Greater number of lower quartiles then Class B as the imagie shows. Class A has 65-75 while class B has 70-75.
Answer:
Step-by-step explanation:
The square in the middle has a length and width of 3, so multiply. <u>9</u>.
All of the triangles have a base of 3 and a height of 2. The area equation for triangles is
So base*height is 6. Divide that by 2 or multiply by 1/2.
You get 3. There are 4 triangles, so multiply <em>that</em> by 4. <u>12</u>.
Add 12 and 9 together, and you get:
I hope this helps!
Answer: y = 3x - 2
the equation is y = ax + b (a ≠ 0)
see in the picture, the line passes through (0;-2) and (2;4)
because the line passes through (0;-2) => b = -2
the line passes through (2;4) => 2a + b = 4
have: b = -2
2a + b = 4
⇔ a = 3
b = -2
=> the equation is y = 3x - 2
