Answer:
h(2) = -48
Step-by-step explanation:
Given that,
[tex]h(x)=-3(4)^x[/tex]
We need to find the value of h(2).
Put x = 2 in the given expression i.e.
[tex]h(2)=-3(4)^2\\\\=-3\times 16\\\\=-48[/tex]
So, the value of h(2) is -48.

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.

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
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]
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]

Y=hx+s solve for the equation for h
Answer:
h=y/x
Step-by-step explanation:
Let's solve for h.
y=hx
Step 1: Flip the equation.
hx=y
Step 2: Divide both sides by x.
hx/x=y/x
h=y/x
Answer:
h = [tex]\frac{y - s}{x}[/tex]Step-by-step explanation:
Subtract s
Y - s = hx
divide by x
h = (y - s)/x

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.)

. 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.
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)
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
