Answer:
Since it is a to-scale model,
the ratio of the wingspan to the length of both the airplanes must be equal
wingspan1 = 200 ft wingspan2 = 30 cm
length1 = 240 ft length2 = x cm
wingspan1 / length1 = wingspan2/length2
replacing the variables
200 / 240 = 30 / x
x = 30 * 240/200
x = 36 cm
Therefore, the length of Emma's airplane is 36 cm

one card is drawn from a pack of 52cards each of the 52 cards being equally likely to be drawn. what is the probability that the card drawn is a king?
The probability of drawing a king from a standard deck of 52 cards is 1/13.
In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.
To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).
The total number of possible outcomes is 52 because there are 52 cards in the deck.
The favorable outcomes, in this case, are the four kings.
Therefore, the probability of drawing a king is given by:
Probability = (Number of favorable outcomes) / (Number of possible outcomes)
= 4 / 52
= 1 / 13
Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.
This means that out of every 13 cards drawn, on average, one of them will be a king.
It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.
Each draw is independent, and the probability of drawing a king is constant.

A recipe for 10 servings of raspberry sorbet calls for 2 cups of water, 1ż cups of granulated sugar, and 4 cups of
frozen raspberries, thawed. How many gallons of water would the recipe call for if a school made 320 servings for
students to eat at lunch?
O 4 gallons
O 8 gallons
O 40 gallons
O 80 gallons
its 4 gallons.
Answer:
\(\huge\boxed{\sf 320\ servings = 4\ gallons}\)
Step-by-step explanation:
1 gallon = 16 cups (STANDARD)
For 10 servings:
10 servings = 2 cups of water
10 servings = 2 / 16 gallons
10 servings = 0.125 gallons
For 320 servings:
10 servings = 0.125 gallons
Multiply both sides by 32
10 * 32 servings = 0.125 * 32 gallons
320 servings = 4 gallons
\(\rule[225]{225}{2}\)

Tristan has a pickup truck that could carry 6/7 -cord of firewood. Find the number of trips needed to carry 54 cords of wood.
Tristan needs 63 trips to carry 54 cords of wood.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b, will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given,
1 pick up ⇔ 6/7 cord of wood
Multiply by 54 on both sides
54 pick up ⇔ (6/7)54 cords of wood
Multiply by 7/6 on both sides
54(7/6) pick up ⇔ 54 cords of wood
63 pick up ⇔ 54 cords of wood
Hence for 54 cords of wood Tristan need 63 trips.

In a large population of students, 60% feel like they can do better in their math class. In a random sample of 5 students, what is the probability that at least 2 students feel like they can do better in their math class?
0.0870
0.2304
0.3174
0.6826
0.9130
The probability that at least 2 students feel like they can do better in their math class is E. 0.9130.
How to calculate the probabilityTo find the probability that at least 2 students feel like they can do better, we need to calculate P(X >= 2). This can be done using the cumulative distribution function (CDF) of the binomial distribution:
P(X >= 2) = 1 - P(X < 2) = 1 - P(X = 0) - P(X = 1)
Using the binomial probability formula, we can calculate:
P(X = 0) = (5 choose 0) * 0.6^0 * 0.4^5 = 0.01024
P(X = 1) = (5 choose 1) * 0.6^1 * 0.4^4 = 0.07680
Therefore,
P(X >= 2) = 1 - 0.01024 - 0.07680 = 0.91296
Rounding this to four decimal places, we get: 0.9130
Therefore, the answer is option E: 0.9130.

Determine the volume of the shaded region?
Answer:
volume of shaded region = 112.94 \(cm^{3}\)
Step-by-step explanation:
Volume of a cylinder = \(\pi r^{2}h\)
volume = 22/7 * \(2.5^{2}\) * 14.6
volume = 286.67 \(cm^{3}\) approx
volume of sphere = \(\frac{4}{3} \pi r^{3}\)
volume = \(\frac{4}{3} *\frac{22}{7}*2.4^{3}\)
volume= 57.91 \(cm^{3}\) approx
No, of sphere = 3
Volume of 3 sphere = 3 * 57.91
=173.73 \(cm^{3}\)
Now , volume of shaded region = volume of cylinder - total volume of sphere
volume of shaded region = 286.67 - 173.73
=112.94 \(cm^{3}\)
Find the solution for a 2x2 matrix A:
[4 4
0 1] to the nth power = [ ]
Answer:
Step-by-step explanation:
Answer:
A^n = [4^n 4^n
0 1]
Step-by-step explanation:
To find the solution for the 2x2 matrix A:
[4 4
0 1] to the nth power = [ ]
We can use matrix multiplication to raise A to the nth power. Let's start with n = 1:
A^1 = [4 4
0 1]
Now, let's solve for A^2 by multiplying A^1 by A:
A^2 = A x A^1
= [4 4 [4 4
0 1] 0 1]
= [16 16
0 1]
Next, let's solve for A^3:
A^3 = A x A^2
= [4 4 [16 16
0 1] 0 1]
= [64 64
0 1]
We can see a pattern emerging:
A^1 = [4 4
0 1]
A^2 = [16 16
0 1]
A^3 = [64 64
0 1]
We can generalize this pattern as follows:
A^n = [4^n 4^n
0 1]
Therefore, the solution for the 2x2 matrix A raised to the nth power is:
A^n = [4^n 4^n
0 1]

What would be the first step when solving using the substitution method?
2x + 3y = -12
x = 3y + 3
The first step of substitution method for given system is put x = 3y +3 in place of x into the equation 2x+3y=-12 .
What is the method of substitution for system of equation in two variables ?The system of the equations in two variables x and y consists of two equation of the form a₁ x + b₁ y = c₁
and a₂ x + b₂ y = c₂
where a₁, a₂, b₁, b₂ , c₁, c₂ are constants
For substitution method, first expression of one variable is found from one equation and then put this expression in another equation to create a linear equation in second variable. Solve the linear equation in one variable for second variable and then put the value of second variable in first equation to solve for first variable
Given system of equations is :
2x + 3y = -12 .....(1)
x = 3y + 3 .....(2)
So the first step will be take expression for one variable from one equation and put it into another equation.
Take x = 3y +3 which is an expression for x from equation (2),
Then put it into equation (1)
⇒ 2 (3y +3 ) + 3 y = -12 , This is the first step of substitution method for this variable

They wrote the model `n=40\cdot1.5^{t}` , where `n` is the total number of squirrels and `t` is the number of years since the biologists started counting. How many squirrels do the biologists predict there will be `2` years after they started counting
The number of squirrels that the biologists predict there will be 2 years after they started counting will be 43 squirrels.
How to illustrate the information?It should be noted that a function is used to show the relationship between the variables.
It should be noted that the function that's given is illustrated as:
n = 40 + 1.5t
In this case, it should be noted that t = 2 years.
Therefore, the number of squirrels that the biologists predict there will be 3 years after they started counting will be:
n = 40 + 1.5t
n = 40 + 1.5(2)
n = 40 + 4
n = 43

4 to the 3 power, x 4 to the 4th power, divide by 4 to the 9th power
Answer:
We can simplify the expression as follows:
4^3 * 4^4 / 4^9
First, we can simplify the terms in the numerator by adding the exponents of 4:
4^3 * 4^4 = 4^(3+4) = 4^7
Now, we can substitute this value in the expression:
4^7 / 4^9
To divide powers with the same base, we can subtract their exponents:
4^(7-9) = 4^(-2)
Therefore, the simplified expression is:
4^3 * 4^4 / 4^9 = 4^(-2)
So, the final answer is 1/16 or 0.0625.
A is the average of numbers x and y. find the value of y in terms of A and x
First we need to get the formula for calculating the average of two numbers which is easy because it is (x + y) / 2
So, the equation will be A = (x + y) / 2
Now all we have to do is get 'y' on one side and the rest of the equation on the opposite side and we will have our solution!
A = (x + y) / 2
A * 2 = (x + y) / 2 * 2 # This will get rid of the number 2 on the right hand side
A * 2 = x + y
A * 2 - x = x + y - x # Subtract the variable 'x' from each side.
A * 2 - x = y
And we can flip it around using the reflexive property of equality!
The answer is:
y = A * 2 - x
Hope this helps!
