A single card is drawn from a standard deck of cards. Find the probability if the given information is known about the chosen card. (Enter the probability as a fraction.) P(queen|black)
Answer:
[tex]\frac{1}{13}[/tex]
Step-by-step explanation:
Given: A single card is drawn from a standard deck of cards.
To find: P(queen | black)
Solution:
Probability refers to chances of occurrence of any event.
Use the formula: P(A | B) = P(A∩B) ÷ P(B)
Let A denotes the event that the card drawn is queen.
Let B denotes the event that the card drawn is black.
Total number of cards = 52
Probability = Number of favorable outcomes ÷ Total number of possible outcomes
P(queen ∩ black) = P(card drawn is black and queen)
= [tex]\frac{2}{52}=\frac{1}{26}[/tex]
P(black) [tex]=\frac{26}{52}=\frac{1}{2}[/tex]
Therefore,
P(queen | black) = P(queen ∩ black) ÷ P(black)
= [tex]\frac{\frac{1}{26} }{\frac{1}{2} }=\frac{2}{26}=\frac{1}{13}[/tex]

answer the question in the pic below (math)
Answer:
46.95 in.²
Step-by-step explanation:
Surface area of the kaleidoscope = surface area of a triangular prism = 2(BA) + P*H
Base area (B) = 2(½*bh) = 2(½*1.5*1.3) = 1.95 in.²
Perimeter of base (P) = 1.5 + 1.5 + 1.5 = 4.5 in.
Height of prism (H) = 10 in.
Plug in the values
Surface area = 1.95 + 4.5*10 = 46.95 in.²
Is this correct?
Answer:
B
Step-by-step explanation:
Yes.
Providing FI is a straight line, then FGH + HGI = 180. The angles are supplementary.
If one of them is 89 then the other one must be 180 - 89 = 91
B is the correct answer.
Find the inverse of g(n) = - 3 - 1
Og-1 (n) = -(n-3)-1
9
9-1 (n) = In
g-1 (n) = (n + 1)3 + 3
Og-1 (n) = 3+n3
Answer:
[tex]g'(n) = -\frac{n+1}{3}[/tex]
Step-by-step explanation:
Given
[tex]g(n) = -3n - 1[/tex]
Required
Determine the inverse
[tex]g(n) = -3n - 1[/tex]
Replace g(n) with y
[tex]y = -3n - 1[/tex]
Swap positions of x and y
[tex]n = -3y - 1[/tex]
Make y the subject
[tex]3y = -n - 1[/tex]
[tex]3y = -(n + 1)[/tex]
[tex]y = -\frac{n+1}{3}[/tex]
Replace y with g'(n)
[tex]g'(n) = -\frac{n+1}{3}[/tex]

A crew of highway workers paved 9 mile in 20 minutes. If they work at the same rate, what portion of a mile
Will they pave in one hour?
A-1/150
B-2/45
C-2/5
D-5/2
-2/45.
Step-by-step explanation:
9 times 3 gives you 27 miles a hour. We are not done though. Now we have to find the portion of a mile they pave in one hour would be -2/45, which is B.

. A uniform distribution is having the following shape ___.
A. bell-shaped C. bimodal
B. rectangular D. triangular
Answer:
B. rectangular
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
In this case, the shape of the distribution is rectangular, as each outcome has the same probability of happening. So the correct answer is given by option B.

The volume of a cube is 125 inches cubed. What is the length of each side?
Answer:
5
Step-by-step explanation:
Explanation: All the edges of a cube have the same length, and the volume of a cube is the length of an edge taken to the third power. So the length of the edge of a cube with a volume of 125 is 5.

Find the measure of line segment AB.
Answer:
Measurement of AB = 8.6 units (Approx.)
Step-by-step explanation:
Given:
Coordinate of point A = (3 , 9)
Coordinate of point B = (8 , 2)
Find:
Measurement of AB
Computation:
Distance = √(X1 - X2)² + (Y1 - Y2)²
Measurement of AB = √(3 - 8)² + (9 - 2)²
Measurement of AB = √25 + 49
Measurement of AB = √74
Measurement of AB = 8.6 units (Approx.)

Find the numerical answer to the summation given below.
75
Σ(6η + 10)
n=0
Answer:
[tex]17860[/tex]
Step-by-step explanation:
To answer this, let's recall a few properties of summations:
[tex]\sum_{i=0}^{n}(a_i+b_i)=\sum_{i=0}^{n}a_i+\sum_{i=0}^{n}b_i\\\\ \sum_{i=0}^{n}(c*a_i)=c*\sum_{i=0}^{n}(a_i)\\\\ \sum_{i=0}^{n}(c)=(n+1)*c[/tex]
With these in mind, we can rewrite the given summation as follows:
[tex]\sum_{n=0}^{75}(6n+10)=\sum_{n=0}^{75}6n+\sum_{n=0}^{75}10=6*\sum_{n=0}^{75}n+76*10\\\\ =6*\frac{75*76}{2} +760=3*75*76+760=17860[/tex]
