The answer is C: 3 books, 2.5 weeks.
Answer:
The probability is ![\frac{5}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B9%7D)
Step-by-step explanation:
The total number of students are 200.
number of full timers is 110 and number of part timers is 90.
number of male students is 90 and number of female students is 110.
Let the probability of part timers be P(B).
P(B) =
= ![\frac{9}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B20%7D)
Let the probability of female part timers be P(A)
P(A) = ![\frac{50}{200} = \frac{5}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B200%7D%20%3D%20%5Cfrac%7B5%7D%7B20%7D)
now, the final probability is
= ![\frac{P(A)}{P(B)}](https://tex.z-dn.net/?f=%5Cfrac%7BP%28A%29%7D%7BP%28B%29%7D)
=
Answer:
Look below
Step-by-step explanation:
Ok, you got a Quadrilateral with the side lengths 6, 9, 9, 12
The shortest of B is 2
Find the scale factor of the A to B
6 -> 2
6/2 = 3
Scale factor is 3
Now divide all the sides by scale factor
6/3, 9/3, 9/3, 12/3 = 2, 3, 3, 4
Add them all together to get the perimeter
2+3+3+4 = 12
Perimeter of B is 12
we are supposed to find
Which of these properties is enough to prove that a given parallelogram is also a Rectangle?
As we know from the theorem, if the diagonals of a parallelogram are congruent then the parallelogram is a rectangle.
The other options The diagonals bisect each other is not sufficient because in parallelogram diagonals always gets bisected , parallelogram becomes rectangles only if both the diagonals are of same length.
In a parallelogram The opposite angles and opposite sides are always equal.
Hence the correct option is
The diagonals are congruent.
Around 4.5π. This can be determined by the volume of a sphere formula.
