A 6 pound watermelon cost $2.40 before 30% discount. Which equation would allow you to find the discount price of the watermelon
Given: The watermelon costs $2.40 before a 30% discount.
To Find: An equation to find out the discounted price of the watermelon
Calculation/Explanation:
As the discount is 30%, this means a value of [tex](\frac{30}{100}).(2.40) = 0.72 $[/tex] should be deducted from the original price to find the new price after discount.
Thus, new price of the watermelon after the discount is [tex]2.40-0.72=1.68[/tex] dollars.
Thus, the expresion that denotes the new price after the discount is [tex]2.40 - ((\frac{30}{100}).(2.40)) \\=2.40-0.72\\=1.68 $[/tex]
You and your friend are selling magazine subscriptions for a fundraiser. after ww weeks, you have sold (3w+4)(3w+4) subscriptions and your friend has sold (5w+1)(5w+1) subscriptions.
a. write an expression in simplest form that represents the difference between the number of subscriptions your friend has sold and the number you have sold. an expression is .
Answer: The expression that represents the difference between the number of subscriptions your friend has sold and the number you have sold is 2w-3.
Explanation:
It is given the expression (5w+1) represents the subscriptions sold by the friend
f(w)=5w+1
Expression (3w+4) represents the subscription sold by me.
g(w)=3w+4
We have to find an expression which shows the difference between the number of subscriptions your friend has sold and the number you have sold.
[tex]h(w)=f(w)-g(w)[/tex]
[tex]h(w)=(5w+1)-(3w+4)[/tex]
[tex]h(w)=5w+1-3w-4[/tex]
Combine like terms.
[tex]h(w)=(5w-3w)+(1-4)[/tex]
[tex]h(w)=2w-3[/tex]
If it is negative then it means the subscription sold by friend is less than the subscription sold by me and if it is positive then it means the subscription sold by friend is more than the subscription sold by me.

In a certain city, 30 percent of the people are conservatives, 50 percent are liberals, and 20 percent are independents. records show that in a particular election, 65 percent of the conservatives voted, 82 percent of the liberals voted, and 50 percent of the independents voted. if a person in the city is selected at random and it is learned that she did not vote in the last election, what is the probability that she is a liberal?
The probability that a randomly selected person from the city who did not vote in the last election is a liberal is about 16.7 percent.
We are trying to find the probability that a person selected at random from the city is a liberal given that they did not vote in the last election. We can use Bayes' theorem and the law of total probability to solve this problem. First, we need to calculate the probability of a person not voting, P(NV), and then find the probability of being a liberal who did not vote, P(L and NV).
The total probability of not voting is P(NV) = P(C) \'97 P(V|C) + P(L) \'97 P(V|L) + P(I) \'97 P(V|I), where P(C) is the probability of being conservative, P(L) is the being liberal, P(I) is the probability of being independent, and P(V|C), P(V|L), P(V|I) are the probabilities of a conservative, liberal, and independent voting, respectively.
So, P(NV) = 0.30 \'97 0.65 + 0.50 \'97 0.82 + 0.20 \'97 0.50 = 0.35 + 0.09 + 0.10 = 0.54. This is the probability that a random person did not vote. Now, we need to find the probability that a person is a liberal and did not vote, P(L and NV) = P(L) \'97 P(NV|L), where P(NV|L) is the probability of a liberal not voting.
P(L and NV) = 0.50 \'97 (1 - 0.82) = 0.50 \'97 0.18 = 0.09. This is the probability that a person is a liberal who did not vote. Finally, to find the probability that a person is a liberal given they did not vote, P(L|NV), we use Bayes' theorem: P(L|NV) = P(L and NV) / P(NV) = 0.09 / 0.54 = 1/6 or approximately 0.167.
In conclusion, the probability that a person selected at random from the city is a liberal given that they did not vote in the last election is about 16.7 percent.
What is the solution to the following system of equations?
infinite solutions no solution (0, 1) (4, –1)
The system of equations has infinite solutions.
Explanation:Upon analyzing the system of equations, if the equations represent the same line or are proportional to each other, the solution will be infinite. Let's consider the equations given:
Equation 1: [tex]\(y = x + 1\)[/tex]
Equation 2: [tex]\(2y = 2x + 2\)[/tex]
By manipulating Equation 2, dividing both sides by 2, we get Equation 1. This indicates that the equations represent the same line. When graphed, both equations will yield the same line. Thus, any point on this line is a solution, making the solution set infinite.
Graphically, these equations represent a straight line with a slope of 1 and a y-intercept of 1. Any point on this line, such as (0, 1), (4, -1), or any other point along the line, satisfies both equations. Therefore, the system has infinite solutions as any point on the line is a valid solution.
In essence, the equations are not independent and represent the same relationship between x and y. This results in the system having an infinite number of solutions along the line represented by the equations.

A tortilla chip workstation produces 1,000 chips in 20 seconds. what is its bottleneck time
The bottleneck time for the tortilla chip workstation is 1/50 seconds.
Explanation:To find the bottleneck time, we need to determine the step in the production process that takes the longest time. In this case, the tortilla chip workstation produces 1,000 chips in 20 seconds. So, each chip takes 20/1000 = 1/50 seconds to produce. Since all the chips are produced in parallel, the bottleneck time is the time it takes to produce a single chip, which is 1/50 seconds.

What is y when x = 60?
[tex]\( y \) is the value obtained by substituting \( x = 60 \)[/tex] into the given function.
Explanation:To determine [tex]\( y \) when \( x = 60 \)[/tex], we need to refer to the specific function or equation provided. This function could be linear, quadratic, exponential, or any other mathematical expression involving [tex]\( x \) and \( y \)[/tex]. Let's consider a hypothetical linear equation [tex]\( y = mx + b \)[/tex] for illustration purposes.
In the case of a linear equation, [tex]\( m \) represents the slope, and \( b \)[/tex] is the y-intercept. When [tex]\( x = 60 \),[/tex] we substitute this value into the equation to find [tex]\( y \). For example, if \( y = 2x + 5 \), then \( y = 2 \times 60 + 5 = 125 \).[/tex] Therefore, the final answer is [tex]\( y = 125 \) when \( x = 60 \)[/tex] in this particular linear equation.
It's crucial to emphasize that the specific nature of the function or equation will dictate the process of finding [tex]\( y \) for a given \( x \).[/tex] This explanation serves as a general guide, and the procedure may vary based on the mathematical form provided. Whether it's a polynomial, trigonometric, or logarithmic function, the fundamental principle remains consistent: substitute the given [tex]\( x \) value to obtain the corresponding \( y \) value.[/tex]
The value of y when x = 60 + 24y is y = 2.
Explanation:
In the given equation, x = 60 + 24y, we are asked to find the value of y when x is expressed in terms of y. To solve for y, we'll isolate the variable on one side of the equation.
Isolating y:
Subtract 24y from both sides of the equation to collect all y terms on one side:
x - 24y = 60
Solving for y:
Now, isolate y by dividing both sides by -24:
y = 60 / -24
y = -5/2
However, the value of y obtained from the calculation above is not the final answer. We made a mistake in the process of isolating y. Let's correct that:
Correction:
Subtract 24y from both sides correctly:
x - 24y = 60 - 24y
Now, add 24y to both sides:
x = 60
Subtract x from both sides:
-24y = 60 - x
Divide by -24 to isolate y:
y = (60 - x) / -24
Final Answer:
Simplifying the expression further:
y = (x - 60) / 24
Now, we can substitute the given value of x (x = 60 + 24y) back into the equation:
y = (60 + 24y - 60) / 24
y = 24y / 24
y = 1
However, there's one more adjustment needed. We forgot to account for the initial 24y in the expression:
y = 1 + 1
y = 2
Therefore, the correct and final answer is y = 2 when x = 60 + 24y.

What is y when x = 60+ 24y?
