You draw one card from a 52 card deck. Then the card is replaced in the deck and the deck is shuffled, and your draw again. Find the probability of drawing a five each time.
Answers
Answer:
1/169Step-by-step explanation:
There are 4 five's in the deck.
Probability of drawing a five is:
P (5) = 4/52 = 1/13Since the card is replaced, it has same probability the second time.
So the probability of drawing a five twice is:

What was the difference, in feet, of their starting heights? Do not include units in your answer.
Answers
After 5 sec will be the same seconds of the elevator.
The two elevators will reach the same floor at the same time if they are both going at a constant speed. If one elevator is going faster than the other, it will reach the bottom first and vice versa.
Given that, elevator A speed = 27-21/3-1=6/2=3
Elevator B speed = 23-19/3-1=4/2=2
suppose x second After will be the Elevator be at the same height
when at 1 second, Elevator A is 27, Elevator B is 23
so Elevator A start at height (27+3), Elevator B start at 23+2
30-3x=25-2x
-3x+2x=25-30
-x=-5
x=5
Hence, after 5 sec will be the same seconds of the elevator.

What is x and what is y
Answers
The value of x is 3.6 and the value of y is 13.35.
We are given the equations that:
15 x - 26 = 28°
12 x + 1 = (4 y - 9)°
Now,
15 x - 26 = 28°
Add 26 to both the sides:
15 x = 28 + 26
15 x = 54
Divide both sides by 15, we get that:
x = 54 / 15
x = 3.6
Now, we have:
12 x + 1 = (4 y - 9)°
Substitute x = 3.6
12 (3.6) + 1 = 4 y - 9
43.2 + 1 = 4 y - 9
44.2 = 4 y - 9
4 y = 44.2 + 9
4 y = 53.2
y = 53.2 / 4

Therefore, we get the value of x as 3.6 and the value of y as 13.35.

How to find the coordinates of the image of a triangle
In this problem we find the locations of the three vertices of a triangle, which is modified by a non-rigid transformation rule, that is, a transformation that does not conserve the original form of the triangle. If we know that A(x, y) = (7, 6), B(x, y) = (- 3, 5) and C(x, y) = (- 4, 9), then the vertices of the image of the triangle are, respectively:
A'(x, y) = (2 · 7, 6 - 3)
A'(x, y) = (14, 3)
B'(x, y) = (2 · (- 3), 5 - 3)
B'(x, y) = (- 6, 2)
C'(x, y) = (2 · (- 4), 9 - 3)

9. If there are 5 points on a paper such that no three points are on a straight line, then how many
lines can be drawn through them?
a. 4
cb-s
C. 8
d. 10
Answers
The number of lines drawn through the 3 collinear points is 10, so the correct option is option d) 10.
It is said that there are 5 points such that no three points out of them are lying in a straight line. This refers to the points being collinear.
Collinear points are associated with three or more different points that do lie on the same straight line and thus, non-collinear points will be defined as points that do not lie on the same straight line.
This means that the points that are non-collinear cannot be connected together via a single line as they are not lying in the same line.
For non-collinearity, not more than two points should be lying in the same straight line.
This is what is given in the question which says that no 3 points can lie on the same line joined through a straight line.
However it is not necessary that the points that are non-collinear will also not lie on the same plane, that is, exhibit the coplanar property.
So hence, non-collinear points are independent of the coplanarity property which means that points that cannot lie on the same line can lie on the same plane.
This is the case given here as it is said that the 5 points that are non-collinear in nature, however, do lie on the same plane which is a single paper. They are coplanar as they lie on the same plane of the paper.
A solution is required to be derived where the 5 points need to be connected so that the above conditions are to be satisfied.
The points must be placed in such a way that no 3 points are collinear but they all must lie on the same plane.
This means that 1 or 2 points are allowed to lie on the same line. Thus, if a figure can be drawn out of these conditions it will form a star-shaped figure enclosed inside a pentagon. (Figure attached at the end)
The number of lines that can be drawn through them satisfying the condition is to be found out. So all the possible pairs are connected via straight lines drawn.
As it can be seen in the figure below if there are 5 points A, B, C, D, and E such that no three points lie on the same line there are 10 lines that are possible that can be drawn connecting them.
The pairs are however considered distinctly which means that either of the lines AB or BA must be taken for example. Both are not to be taken as they represent the same straight-line pair.
So the number of possible connections in the setup given below (from the figure) is 10 namely AB, BC, AE, CA, CD, DE, CE, DA, DB, and BE.
Thus, the number of lines that can be drawn through the 5 points such that no 3 points are collinear is 10.

Regarding the given problem;
The pool has a volume of 256 yd³.
Convert the yd³ volume to gallons.
201.976 gallons are in 1 yd³.
As a result, multiply both sides by 256 to get the total volume, which is 256 yd³.
201.976 yd³ are equal to 256 gallons.
