A recent study of 200 nurses found that of 125 female nurses 56 held bachelor's degrees; of the males 34 held bachelor's. If a n

bonufazy [111]

Need to develop a contingency table (often used for calculating probabilities when the focus is on conditional probability).

The nurse is either M or F.
The nurse either has a BS degree or does not.

Since there are 125 female nurses, and 56 of those held bachelors degrees, that leaves (125-56), or 69, who did not hold bachelors degrees. Complete this table. I found that there are 75 male nurses and 125 female nurses. Note that 75 and 125 add up to 200 (which is the given number of nurses).

Find the slope of the line satisfying the given condition. Through (3,-6) and (-9,-1)

inessss [21]

Answer:

C) -5/12

Step-by-step explanation:

To find the slope of a line with given points, you divide the difference of y-coordinates by the difference of the x-coordinates of those same 2 points.

x's:-9-3=-12

y's:-1-(-6)=5

Then, you put the answer of the y's in the numerator, and x's in the denominator, giving you 5/-12, but you can't have a negative in the denominator, moving it up to become -5/12 as the slope.

A triangle has vertices at (-1,5), (4,2), and (0,0). What is the perimeter of the triangle

yan [13]

The perimeter of the triangle is 15.4 units.

Step-by-step explanation:

The triangle has vertices at (-1,5), (4,2), and (0,0).

To find the perimeter of the triangle, you need to find the distance of the three points which is the length of the three sides of the triangle.

Let us consider the points as A (-1,5) and B (4,2) and C (0,0).

The distance formula is given by :

⇒ $\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }$
