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]

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)
Answers
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]

Four buses carrying 153 high school students arrive to Montreal. The buses carry, respectively, 36, 46, 32, and 39 students. One of the students is randomly selected. Let X denote the number of students that were on the bus carrying this randomly selected student. One of the 4 bus drivers is also randomly selected. Let Y denote the number of students on his bus. Compute the expectations and variances of X and Y: E(X)
Answers
Answer:
E(X) = 38.9346
Var(X) = 25.588
E(Y) = 38.25
Var(Y) = 26.1875
Step-by-step explanation:
Given - Four buses carrying 153 high school students arrive to Montreal. The buses carry, respectively, 36, 46, 32, and 39 students. One of the students is randomly selected.One of the 4 bus drivers is also randomly selected.
To find - Compute the expectations and variances of X and Y.
Proof -
Let us assume that,
X be The number of students that were on the bus carrying this randomly selected student.
Y denote the number of students on his bus.
Now,
E(X) = [tex]\frac{36(36) + 46(46) + 32(32) + 39(39)}{153}[/tex]
= [tex]\frac{5957}{153}[/tex]
= 38.9346
⇒E(X) = 38.9346
Now,
E(Y) = [tex]\frac{36 + 46 + 32 + 39}{4}[/tex]
= [tex]\frac{153}{4}[/tex]
= 38.25
⇒E(Y) = 38.25
Now,
Var(X) = [tex]\frac{36(36 - 38.9346)^{2} + 46(46 - 38.9346)^{2} + 32(32 - 38.9346)^{2} + 39(39 - 38.9346)^{2}}{153}[/tex]
= [tex]\frac{310.0276 + 2296.3144 + 1308.5091 + 0.1668}{153}[/tex]
= [tex]\frac{3915.0179}{153}[/tex]
= 25.588
⇒Var(X) = 25.588
Now,
Var(Y) = E(Y²) - [E(Y)]²
= [tex]\frac{36^{2} + 46^{2} + 32^{2} + 39^{2} }{4} - (38.25)^{2}[/tex]
= [tex]\frac{5957}{4} - 1463.0625[/tex]
= 1489.25 - 1463.0625
= 26.1875
⇒Var(Y) = 26.1875

Answers
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
