For given ratio of orange juice and pineapple juice i.e. 5/6, proportion used to find the amount of orange juice, j, that is needed to add to 21 L of pineapple juice will be 5 over 6 equals j over 21 i.e. 5/6=j/21.
What exactly is a ratio?
Fractions are commonly used to describe ratios and proportions. A ratio is demonstrated when a fraction is expressed as a:b, whereas a percentage indicates that two ratios are equal. a and b can be any two numbers in this situation. The ratio and proportion are two fundamental ideas that lay the groundwork for comprehending other concepts in mathematics and science.
We use the concept of ratio and proportion in our daily lives, such as in business when dealing with money or in cooking.
As a result, when b is larger than zero, the ratio, such as a:b, defines the relationship between two variables. For example, the 2:4 ratio is expressed as 2:4 = 1:2.
Now,
Given that In recipe ratio of orange juice / pineapple juice =5/6
then to make a recipe with 21 L of pineapple juice, the orange juice (j)
needed will be
5/6=j/21
j=17.5 L
hence,
proportion used to find the amount of orange juice, j will be 5 over 6 equals j over 21 i.e. 5/6=j/21.

A magician shuffles a standard deck of playing cards and allows an audience member to pull out a card, look at it, and replace it in the deck. Three additional people do the same. Find the probability that of the 4 cards drawn, at least 1 is a face card. (Round your answer to one decimal place.
The probability that at least 1 of the 4 cards drawn is a face card is 0.6.
How to find probability of 4 cards drawn?A typical deck contains 52 cards in total. There are 51 cards left in the deck after the first spectator draws a card. The replacement card leaves 52 cards in total, which is the same as before. The number of cards remains 52 for all four draws since each succeeding audience member will draw a card and replace it.
Finding the likelihood that none of the four cards are face cards and subtracting it from one will give us the chance that at least one of the four cards is a face card.
A deck of cards has 12 face cards (4 jacks, 4 queens, and 4 kings). Consequently, the likelihood that a single draw will not provide a face card is:
P(not a face card)=(52 - 12)/(52)=(40/(52)=(10/13).
The likelihood that none of the four draws will produce a face card is:
P(no face cards are present) = (10/13)4 = 0.432
As a result, the likelihood that at least 1 of the four cards revealed is a face card is as follows:
P(none are face cards) = 1 - P(at least one is a face card) = 1 - 0.432 = 0.568
The chance, rounded to one decimal place, is roughly 0.6.
Consequently, there is a 0.6 percent chance that at least one of the four cards will be a face card.

The figure below is dilated by a factor of 4 centered at the origin. Plot the resulting image
The resulting image of the dilated figure has vertices at (-8, -4), (8, -8), and (4, 8).
What is dilation?Resizing an item uses a transformation called dilation. Dilation is used to enlarge or shorten the structures. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. The initial form should be stretched or contracted during dilatation.
To dilate the given figure by a factor of 4 centered at the origin, we need to multiply the coordinates of each vertex by 4.
The new coordinates of B will be:
x-coordinate: 4 x (-2) = -8
y-coordinate: 4 x (-1) = -4
So the new vertex B' is (-8, -4).
The new coordinates of C will be:
x-coordinate: 4 x (2) = 8
y-coordinate: 4 x (-2) = -8
So the new vertex C' is (8, -8).
The new coordinates of D will be:

The short-run total cost is TC is wL + rK and short-run average cost curve is TC/Q. The SMC is 4.01 and the SMC curve intersects the SAC curve at its lowest or minimum points because the average cost is a weighted average of the marginal cost and the fixed cost.
What is the firm short-run total cost curve and short-run average cost curve functionA. To calculate the firm’s short-run total cost curve, we need to calculate the total cost at each level of output. The short-run total cost can be represented as follows:
TC = wL + rK,
where w is the wage rate, L is the labor used, r is the interest rate, and K is the capital used. In this case, w = $4 and r = $1.
To calculate the short-run average cost curve, we need to divide the total cost by the level of output:
SAC = TC / Q
Where Q is the level of output.
B. The short-run marginal cost function can be calculated as the change in total cost for a small change in the level of output:
SMC = dTC / dQ
At a level of output of 25, the labor used is L = 25 / 2 = 12.5. The total cost can be calculated as follows:
TC = 4 * 12.5 + 1 * 100 = 50 + 100 = 150
So, the short-run average cost is SAC = 150 / 25 = $6 and the short-run marginal cost is SMC = dTC / dQ. To calculate the derivative, we need to use the production function given:
Q = 2 * sqrt(KL)
Taking the derivative with respect to L, we get:
dQ / dL = (1 / (2 * sqrt(KL))) * 2K = K / (sqrt(KL))
Substituting the values, we get:
SMC = 4 + (1 / (sqrt(100 * 12.5)))
At a level of output of 200, the labor used is L = 200 / 2 = 100. The total cost can be calculated as follows:
TC = 4 * 100 + 1 * 100 = 400
So, the short-run average cost is SAC = 400 / 200 = $2 and the short-run marginal cost is SMC = dTC / dQ. To calculate the derivative, we need to use the production function given:
Q = 2 * sqrt(KL)
Taking the derivative with respect to L, we get:
dQ / dL = (1 / (2 * sqrt(KL))) * 2K = K / (sqrt(KL))
Substituting the values, we get:
SMC = 4 + (1 / (sqrt(100 * 100)))
SMC = 4.01
C. To draw the graph for the SAC and SMC, we need to calculate the SAC and SMC for different levels of output. We can then plot the SAC and SMC against the level of output to obtain the graphs.
D. The SMC curve intersects the SAC curve at its lowest or minimum points because the average cost is a weighted average of the marginal cost and the fixed cost. When the level of output is low, the marginal cost is high and the fixed cost is a large portion of the total cost. As the level of output increases, the marginal cost decreases and the fixed cost becomes a smaller portion of the total cost. As a result, the average cost decreases and reaches a minimum at the point where the marginal cost intersects the average cost.

What do you mean by SRS (Simple Random Sample)?Simple Random Sample (SRS) is a statistical technique for selecting a sample from a population, where each individual or item in the population has an equal chance of being selected for the sample. In other words, a simple random sample is a representative subset of a population where every individual or item in the population has an equal chance of being selected for the sample.
To take a simple random sample, each individual in the population is assigned a unique number, and then random numbers are generated to select the required number of individuals for the sample. This method ensures that the sample is not biased towards any particular subset of the population, and that the sample is representative of the whole population.

four times the sum of the three consecutive even intergers is 240 more than six times the smallest integer.
Answer:
Step-by-step explanation:
Let's call the smallest of the three consecutive even integers "x". Since they are consecutive and even, we know that the next two integers must be "x + 2" and "x + 4".
Now we can set up the equation for the problem:
4 * (x + (x + 2) + (x + 4)) = 240 + 6x
Expanding the parentheses on the left side:
4 * (3x + 6) = 240 + 6x
Simplifying the left side:
12x + 24 = 240 + 6x
Subtracting 6x from both sides:
6x + 24 = 240
Subtracting 24 from both sides:
6x = 216
Dividing both sides by 6:
x = 36
So the smallest of the three consecutive even integers is 36, and the others are 38 and 40.

Grayson would need to invest approximately $10,994 to the nearest dollar for the value of the account to reach $15,000 in 5 years.
What is continuously compounded interest?
Continuous compounded interest indicates that an account balance is constantly earning interest and reinvesting that money so that it, too, earns interest.
The formula for continuous compounding is given by:
[tex]A = Pe^{rt}[/tex]
where A is the amount in the account after t years, P is the principal amount (the amount invested), r is the annual interest rate, and e is the base of the natural logarithm.
We want to find P when A = $15,000, r = 0.04, and t = 5 years.
Substituting these values into the formula, we get:
[tex]15000 =Pe^{0.04*5}[/tex]
Simplifying the right-hand side, we get:
[tex]15000 =Pe^{0.2}[/tex]
Dividing both sides by e^(0.2), we get:
[tex]P= \frac{15000}{e^{0.2}}[/tex]

How to find the sum of the infinite geometric series?Since we have the expression for the sum of the infinite geometric series
[tex]\[ \sum_{n=0}^{\infty} 6(0.75)^{n} \][/tex]
STEP 1:
The first term of the infinite geometric series is 6. Thus, a1 = 6.
STEP 2:
The common ratio of the infinite geometric series is 0.75. Thus, r = 0.75
STEP 3:
The common ratio is less than one.
Because Sn = a/(1 - r) is the formula we use when the common ratio is less than 1.
STEP 4:
Sn = a/(1 - r)
Sn = 6/(1 - 0.75) = 24

the equation of a curve is given by
y=x^3/3+7x^2/2+10x+d, where d is a
constant. Find the possible values of d
when the x-axis is tangent to the curve
v=x^3/3+7x^2/2+10x+d.
Answer: A tangent to the x-axis means that the y-coordinate of the point of tangency is 0. So, we can find the possible values of d by setting y = 0 and solving for x:
0 = x^3/3 + 7x^2/2 + 10x + d
This is a cubic equation, so it can be solved using various methods such as factoring, completing the square, or using a numerical method such as the Newton-Raphson method. If the equation can be factored or the method used is numerical, there might be multiple possible values of d. If the method used is completing the square, there would be only one possible value of d.
However, without a specific method, it's not possible to find the exact value(s) of d. The possible values of d will depend on the specific solution method used to solve the equation.

For the given set, first calculate the number of subsets for the set, then calculate the number of proper subsets.
{10, 15, 14, 20, 11}
...
Step-by-step explanation:
A set is a collection of distinct elements, and a subset is a collection of elements taken from a larger set. In this case, the set is {10, 15, 14, 20, 11}.
To calculate the number of subsets, we can use the formula for the number of subsets of a set with n elements, which is 2^n. So, the number of subsets of the set {10, 15, 14, 20, 11} is 2^5 = 32.
To calculate the number of proper subsets, we need to exclude the empty set (Ø) and the set itself from the total number of subsets. So, the number of proper subsets is 32 - 2 = 30.
Therefore, there are 32 subsets and 30 proper subsets of the set {10, 15, 14, 20, 11}.
