Out of a deck of 52, what is the probability you draw 4 cards and all four cards are DIAMOND cards? (You can see a deck of cards here.)
a
.0026
b
.00000015
c
.077
d
.25
This decimal value is the approximation of the fraction 11/4165
================================================================
Explanation:
There are 13 diamonds out of 52 total.
The probability of getting a diamond card is 13/52.
After selecting that diamond card and not putting it back, we have 13-1 = 12 diamonds left out of 52-1 = 51 left. The probability of getting another diamond is 12/51.
Then the probability of getting a third diamond is 11/50, and finally 10/49 represents the probability of getting a fourth diamond. Each time we need a new probability, we just subtract 1 from the numerator and denominator.
The numerators are: 13, 12, 11, 10
The denominators are: 52, 51, 50, 49
We'll multiply the four fractions to get our final answer
(13/52)*(12/51)*(11/50)*(10/49) = 0.00264105642257
This rounds to 0.0026 which is roughly a 0.26% chance
The answer as an exact fraction is 11/4165

Answer:
[tex]\boxed{\tt x=58^{\circ}}[/tex]
Step-by-step explanation:
From the given diagram, we see that ∠YOZ and ∠XOY are complementary angles.
Complementary angles: two angles with measures that add up to 90°.
[tex]\tt m\angle XOY+m\angle YOZ=90^{\circ}[/tex]
[tex]\tt \angle XOY+\angle YOZ=90^{\circ}[/tex]
[tex]\tt 32^{\circ}+x=90[/tex]
Subtract 32 from both sides:
[tex]\tt 32^{\circ}+x-32^{\circ}=90^{\circ}-32^{\circ}[/tex]
[tex]\tt x=58^{\circ}[/tex]

(7).Given f(x) =
[tex] \frac{1}{x ^{2} - 1} [/tex]
and g(x)=
[tex] \frac{x}{x + 2} [/tex]
where x & R.
Find the ;
(i). inverse of g(x) (ii). Expression
[tex] g{x} ^{ - 1} f{x}[/tex]
iii). Largest domain of f(x) and g(x) respectively.
Answer:
The inverse of g(x) is [tex]g^{-1}(x)=\frac{2x}{1-x}[/tex]
The domain of g(x) is (-∞,-2)U(-2,∞)
The domain of f(x) is (-∞,-1)U(-1,1)U(1,∞)
Step-by-step explanation:
Find the inverse of g(x).
[tex]y=\frac{x}{x+2}[/tex]
Solve for x
[tex]x=y(x+2)[/tex]
[tex]x=xy+2y[/tex]
[tex]x(1-y)=2y[/tex]
[tex]x=\frac{2y}{1-y}[/tex]
[tex]g^{-1}(x)=\frac{2x}{1-x}[/tex]
Find the domain of g(x)
[tex]g(x)=\frac{x}{x+2}[/tex]
Numerator and denominator have domain
(-∞,∞).
However, g(x) is undefined if the denominator is 0. Hence, x=-2 must be taken out of the domain. So, the domain of g(x) is
(-∞,-2)U(-2,∞).
Find the domain of f(x)
[tex]f(x)=\frac{1}{x^{2} -1}[/tex]
The numerator and denominator have the domain
(-∞,∞)
However, f(x) is undefined if the denominator is 0. This rules out +1 and -1. So, the domain of f(x) is
(-∞,-1)U(-1,1)U(1,∞)
I am not sure what you mean for (ii).

A customer in a store had two 50% off coupons. She tried to buy a purse with them, gave them to the cashier
and explained that the two 50% off coupons should mean that she gets the purse for free. The cashier
disagreed and refused to give the purse for free. What discount should two 50% off coupons actually give at the
store?
Answer:
Well, I think that the 50% coupons would give you only 50% off of your entire purchace. Not 100% off.

Step-by-step explanation:
A square piece of land is to be divided into 4 square quadrants of equal size. On a map, the entire piece of land measures 6 inches long on each side.
The scale of the map is inch = 20 feet. How much area will be included in each quadrant when the piece of land is divided?
A.43,200 ft2
B.27,000 ft2
C.14.400 ft2
D.10,800 ft2
Answer:
The scale of the map is inch = 20 feet.
This statement must be incorrect or the fraction of the inch is missing.
Because 6" long, at a scale of one inch = 20 feet, would only be 120 feet x 120 feet.
120 x 120 = 14,000 ft^2 and each of the four quadrants wouls only be 3600 ft^2.

Ms.Li spent $840 on a vacation. She spent 2/3 of the amount on a train ticket and 1/2 of the remaining amount on food. How much did she spend on the ticket and food together?
Answer:I would say that the answer is 700 is the answer is incorrect my apologies.
Step-by-step explanation: Ms.Li spent $840 on vacation, She spent 2/3 of the amount on a train ticket and 1/2 of the remaining amount on food. How much did she spend on ticket and food altogether= 840 2/3 = 560
840-560 = 280
half of 280 = 140
560+140 = 700

Help me with this please!!
Answer:
90 Degrees
Step-by-step explanation:
This is a very cool theorem. When the longest side of a triangle is the diameter of the circle, which in the picture you can see it is, the angle opposite to it is ALWAYS 90 degrees. Remember that the points have to be on the circle for this theoroem to work. I forget what the theoroems is called, but it is very helpful.

What is the surface area of the regular pyramid given below?
A. 280 units2
B. 329 units2
C. 189 units2
D. 140 units2
The surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²
Area of a PyramidFrom the question, we are to calculate the surface area of the regular pyramid
The surface area of the pyramid = Sum of area of the triangular faces + Area of the square base
∴ Surface area of the pyramid = [tex]4(\frac{1}{2}bh)+ b^{2}[/tex]
Surface area of the pyramid = 2bh + b²
Where b is the base
and h is the perpendicular height of each triangular faces
In the given diagram,
b = 7
h = 10
∴ Surface area of the pyramid = 2×7×10 + 7²
Surface area of the pyramid = 140 + 49
Surface area of the pyramid = 189 units²
Hence, the surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²
