You sell 600 shares of AVG Technologies (AVG). You purchased the stock at $2.99 per share and sold it at $0.88 per share. What was the percent decrease in the stock? Round to the nearest whole percent.
71%
29%
42%
24%
Answer:
71%
Step-by-step explanation:
To calculate the percent decrease in the stock, we can use the following formula:
Percent decrease = ((Original value - New value) / Original value) * 100
Given:
Original value (purchase price) = $2.99 per share
New value (selling price) = $0.88 per share
Plugging in the values into the formula:
Percent decrease = ((2.99 - 0.88) / 2.99) * 100
Percent decrease = (2.11 / 2.99) * 100
Percent decrease = 70.57%
Rounding to the nearest whole percent, the correct answer is 71%.

What is a linear equation in mathematics?
A linear equation in algebra is one that only contains a constant and a first-order (direct) element, such as y = mx b, where m is the pitch and b is the y-intercept.
Sometimes the following is referred to as a "direct equation of two variables," where y and x are the variables. Direct equations are those in which all of the variables are powers of one. In one example with just one variable, layoff b = 0, where a and b are real numbers and x is the variable, is used.
2000 = $602
2003 = $651
= 651 - 602/602 * 100

D. 1/6
The probability that the point land in square S will be 5/6.
What is probability?
Probability is a branch of mathematics in which the chances of experiments occurring are calculated. It is by means of a probability, for example, that we can know from the chance of getting heads or tails in the launch of a coin to the chance of error in research.
The probability that the point does not land in triangle T is equal to subtract the area of triangle T from the area of rectangle and divided the result by the the area of rectangle
so, Find out the area of rectangle
A = (6)(4)
= 24 unit²
Find out the area of triangle T
A = 1/2(2)(4)
= 4 unit²
The probability is equal to
P = (24-4) / 24

This means x is between or including 3 to 80 . a) Find the marginal profit function. b) Find the Critical value c) If they need to sell at least 300 bikes but not more than 8000 bikes, find the maximum profit, the number of bikes that must be sold to reach the maximum profit. Be sure to show a table with the values you should check to find the Maximum. (Hint 3≤x≤80 )
According to the given data the maximum profit is $780,000 when 6,500 bikes are sold.
What is marginal profit function?The marginal profit function represents the rate at which the profit changes as the number of units sold changes. It is the derivative of the profit function with respect to the number of units sold. The marginal profit function is important in business because it helps companies to determine the optimal level of production that maximizes profit. The critical value of the marginal profit function (when it equals zero) indicates the point where the profit function changes from increasing to decreasing, or vice versa, which can help companies to identify the optimal production level that maximizes profit.
According to the given information:a) To find the marginal profit function, we need to take the derivative of the profit function with respect to x:
P'(x) = -4x + 260
b) To find the critical value, we need to set the marginal profit function equal to zero and solve for x:
-4x + 260 = 0
x = 65
Therefore, the critical value is x = 65.
c) To find the maximum profit, we need to evaluate the profit function at the endpoints of the given interval (3 and 80) as well as at the critical value (65), and then compare the values to see which one is the largest. We can use a table to organize the values:
x P(x)
3 190
65 7800
80 2600
Therefore, the maximum profit is $780,000, which occurs when 6,500 bikes are sold (since each x represents 100 bikes).

The solution to the equation ln {A} = .552 is A = e[tex]^{0.552}[/tex] = 2.7. In order to calculate eˣ for both sides of the equation ln {A}=.552, one must first understand what the equation signifies.
What is logarithmic equation?A logarithmic equation is an equation involving logarithms of different variables. Logarithmic equations are used to solve various types of problems. It uses the logarithmic properties of multiplication and division to simplify the equation.
This equation is a logarithmic equation, in which ln (natural logarithm) is used to represent a number's exponential value.
This means that the equation is actually stating that A is equal to e raised to the power of 0.552 (e[tex]^{0.552}[/tex] ).
In order to solve for A, one must use the basic rule of logarithms: for any logarithmic equation of the form ln {A} = B, A = e^B.
Therefore, the solution to the equation ln {A} = .552 is
A = e[tex]^{0.552}[/tex] .
This equation can be solved using basic algebra, as e[tex]^{0.552}[/tex] can be replaced with an equivalent expression.
The equation can be rewritten as A = (e[tex]^{0.5}[/tex])(e[tex]^{0.052}[/tex]).
The value of e[tex]^{0.5}[/tex] can be calculated using a calculator, and can be rounded to the nearest tenth.
The value of e[tex]^{0.052}[/tex] can then be calculated, which can also be rounded to the nearest tenth.
Adding the two values together will give the solution to the equation, which is A = 2.7.
Therefore, the solution to the equation ln {A} = .552 is
A = e[tex]^{0.552}[/tex]
= 2.7.

Complete this statement given that g(x) = -f(x): "This graph of function g is graph (C) because the graph of function g is the result of a reflection applied to the graph of function f."
The graph of function g is a reflection of the graph of function f across the x-axis because of the negative sign in front of f(x) in the definition of g(x) = -f(x). This reflection results in a vertical flip of the graph. When a function is multiplied by a negative value, it gets reflected across the x-axis. The "C" option in the dropdown menu indicates a reflection across the x-axis.
The transformation applied to the graph of function f to get the graph of function g is a reflection, and it occurs due to the negative sign (-) in front of f(x) in the definition of g(x) = -f(x).

2. Victoria deposits $1500 into each of two savings accounts. • Account A earns 3.5% annual simple interest. • Account B earns 3.5% interest compounded annually. Victoria does not make any additional deposits or withdrawals into either account. Which amount is closest to the difference between the interest Victoria would earn in Account B and the interest she would earn in Account A at the end of 4 years?
the amount closest to the difference between the interest Victoria would earn in Account B and the interest she would earn in Account A at the end of 4 years is $22.32.
What is compound interest?
The interest on savings that is computed on both the initial principal and the interest accrued over time is known as compound interest. Compound interest is computed by multiplying the starting principal amount by one and the annual interest rate is raised to the number of compound periods minus one. The final step is to deduct the initial loan principal from the calculated value.
Using the formula for compound interest, we can find the amount at the end of 4 years in Account B:
[tex]A = P * (1 + r/n)^{(nt) = $1500 * (1 + 0.035/1)^{(14) = $1732.32[/tex]
The interest earned in Account B over 4 years is the difference between the amount at the end of the period and the principal:
I = A - P = $1732.32 - $1500 = $232.32
Therefore, the difference between the interest Victoria would earn in Account B and the interest she would earn in Account A at the end of 4 years is approximate:
$232.32 - $210 = $22.32
Therefore, the amount closest to the difference between the interest Victoria would earn in Account B and the interest she would earn in Account A at the end of 4 years is $22.32.

3. Find the equation of a circle with the endpoints of the diameter at (0, 8) and (0,-2)
Step-by-step explanation:
remember, the general equation for a circle is
(x - h)² + (y - k)² = r²
r is the radius, (h, k) is the center point of the circle.
the line (0, 8) to (0, -2) is a diameter, so, the center of the circle is the midpoint between both points.
remember, the midpoint between 2 points (x1, y1) and (x2, y2) is
((x1+x2)/2, (y1+y2)/2)
in our case :
((0+0)/2, (8-2)/2) = (0, 3)
the distance from the center point to the endpoint is e.g
(0, 3) to (0,8) = 8-3 = 5.
and that is the radius.
the equation of the circle is therefore :
(x - 0)² + (y - 3)² = 5²
x² + (y - 3)² = 25
The tree diagram represents the sample space for the repeated experiment of a coin being tossed 4 times.
Determine P(at least 2 talls).
The probability of getting at least 2 tails in 4 coin tosses is 11/16 or approximately 0.6875.
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
According to given information:To determine P(at least 2 tails), we need to add up the probabilities of all the outcomes in the sample space that have at least 2 tails.
Looking at the tree diagram, we can see that there are 11 outcomes that have at least 2 tails:
TTTT TTTH TTHT TTHH THTT THHT THTH HTTT HTTH HTHT HHTT
The probability of each outcome can be found by multiplying the probabilities along the branches that lead to that outcome. Since the coin is fair, the probability of getting heads or tails on any given toss is 1/2.
So for example, the probability of the outcome TTHH is (1/2) x (1/2) x (1/2) x (1/2) = 1/16.
We can find the probability of getting at least 2 tails by adding up the probabilities of the 11 outcomes listed above:
P(at least 2 tails) = [tex](1/2)^4[/tex] + 4 x [tex](1/2)^3[/tex] x (1/2) + 6 x [tex](1/2)^2[/tex] x [tex](1/2)^2[/tex]
P(at least 2 tails) = 1/16 + 4/16 + 6/16 = 11/16
Therefore, the probability of getting at least 2 tails in 4 coin tosses is 11/16 or approximately 0.6875.
