Evan invested $2500 in the stock market.
Four months later, the value of the
investment dropped to $2248. Find the
average monthly change in the value of
the investment.
Answer:
63
Step-by-step explanation:
Value dropped = 2500 - 2248 = 252
divide 252 across 4 months
252/4 = 63
The average monthly change in the value of the investment is $63.
Given that, Evan invested $2500 in the stock market. Four months later, the value of the investment dropped to $2248.
What is the investment?Investment definition is an asset acquired or invested in to build wealth and save money from the hard earned income or appreciation. Investment meaning is primarily to obtain an additional source of income or gain profit from the investment over a specific period of time.
Now, change in investment is
2500-2248 = 252
The average monthly change
= 252/4
= 63
Hence, the average monthly change in the value of the investment is $63.

Thomas records the masses of several rocks as 7.40 g, 7.85 g, 7.60 g, and 7.40 g. what is the mode of thomas’s data set? 0.45 7.40 7.55 7.60
By observation or by inspection, 7.40 appears the most, thus mode.
What Is the Mode?The value that appears most frequently in a data set is called the mode. One mode, several modes, or none at all may be present in a set of data. The mean, or average of a set, and the median, or middle value in a set, are two more common measurements of central tendency.
Data can be disseminated in statistics in a number of different ways. The traditional normal (bell-curve) distribution is the one that is referenced the most. The midpoint of this distribution, as well as some others, coincides with the peak frequency of observed values and is where the mean (average) value is located.
The mean, median, and mode all have the same values for such a distribution. This indicates that this value—the one that appears the most frequently in the data—is the average value, the middle value, and the mode.
When analyzing categorical data, such as automobile models or soda taste varieties, where a mathematical average median value based on ordering cannot be computed, mode is most helpful as a gauge of central tendency.

Does this graph show
a function? Explain how you know.
O A. Yes; the graph passes the vertical line test.
• B. Yes; there are no y values that have more than one x-value.
O C. No; the graph fails the vertical line test.
O D. No; there are y values that have more than one x-value.
PLEASE HURRY
The answer is option C, No; the graph fails the vertical line test.
The graph given doesn't show a function.
The method that is used to determine whether a given graph is a function or not is called the vertical line test. In this test, a vertical line is drawn at an arbitrary point x. If this line touches the given graph at more than 2-points, then the given graph is not a function.
In the given graph, if we draw a vertical line for any x > -1, then this vertical line touches the graph at more than two points.
In other words, for any value x > -1, the corresponding value of y is not unique.
So, the answer is option C, No; the graph fails the vertical line test.

Miranda simplified the expression 5x+9y-4. She says the answer is 10xy.
What error did Miranda make while combining like terms?
What should her answer be?
Miranda made error by combining unlike terms, She added 5x and 9y then subtracted 4 from the answer. Answer is already in simplified form, it cannot be simplified further.
What are like and unlike terms?Like terms are ones whose exponent power and variables are the same. These variables' coefficients could differ. Terms that are comparable to one another are known as algebraic terms. As an illustration, consider the algebraic statement 8y + 2y, where y is the same variable as in the expression but has different coefficients.
Terms that have variables and exponents that differ from one another are said to be unlike terms. In contrast to terms, an expression is known to obtain when the coefficient, variables (in this case, two variables), and exponent powers (if any) are all distinct. Contrary to algebraic terms, the algebraic formula 3x + 9y is known as, where x and y are two separate variables with different coefficients.

select the correct answer. what is the slope of the line that goes through the points (-4,2) and (8,5)?
A. "-4"
B. "-1/4"
C. 1/4
D. 4
Answer: The slope of the line that goes through the points is = ¼
Step-by-step explanation:
Define Slope:
The slope is a numerical value that describes the steepness of a line and is usually determined by calculating the ratio of the vertical distance to the horizontal distance (rise over run) between two points.
The slope of the line that goes through the points (-4,2) and (8,5).
Let, X1=-4
Y1=2
X2=8
Y2=5
We can use m=(y2-y1) / (x2-x1)
replace with x1, y1 and x2, y2 values in this equation
We can write: m=[(5-2) / (8-(-4))]
Solve it: M= 3/12
M=1/4
So, the slope of the line that goes through the points is = ¼.

The figure below shows an image of Pac-Man from the classic video game. The "mouth" of Pac-Man forms a central angle of 55.0° in a circle with radius 4.00 millimeters.
Using the length of the perimeter of the Pacman is: 29.29 mm.
How to Find the Length of an Arc?Length of an arc = ∅/360 × 2πr
The length of the perimeter of the Pacman = length of the larger arc formed + 2r
∅ = 360 - 55 = 305°
r = 4.00 mm
The length of the perimeter of the Pacman = ∅/360 × 2πr + 2r
Substitute
The length of the perimeter of the Pacman = 305/360 × 2π(4.00) + 2(4.00)
The length of the perimeter of the Pacman = 21.29 + 8.00
The length of the perimeter of the Pacman = 29.29 mm
Therefore, using the length of the perimeter of the Pacman is: 29.29 mm.

simplify the equation 12-2/6+4
i need help asap !!!!
Answer:
47 / 3 ( Or 1 if you typed it wrong)
Step-by-step explanation:
When simplifying an equation like this, we always want to do our multiplication and division before addition and subtraction.
So for the first step, let's simplify the expression down to only addition and subtraction...
12 - 2 / 6 + 4 =
12 - (2 / 6) + 4 =
12 - 1/3 + 4
Now we can combine everything together from left to right...
(12 - 1/3) + 4 =
35/3 + 4 =
47 / 3
However...
If the original equation was:
[tex]\frac{12-2}{6+4}[/tex]
Then you would just simplify the top and bottom separately before dividing the two numbers, treating the fraction as parentheses.
So...
(12 - 2) = 10
(6 + 4) = 10
And since 10 / 10 = 1
The answer to the fraction simplification is 1.
The solution of the expression would be 47/3.
Given that,
The expression is,
[tex]12 - \dfrac{2}{6} + 4[/tex]
Now simplify the expression by applying the BODMAS rule,
[tex]12 - \dfrac{2}{6} + 4[/tex]
[tex]12 - \dfrac{1}{3} + 4[/tex]
[tex]16 - \dfrac{1}{3}[/tex]
[tex]\dfrac{(48 - 1)}{3}[/tex]
[tex]\dfrac{47}{3}[/tex]
Therefore, the solution of the expression is 47/3.

Miguel is asked to solve the problem below and wants to convert the values to the same form. Which form would you encourage Miguel to choose?

No answer text provided.
Since 5/6 is a repeating decimal, Miguel should convert the decimal -0.6 to a fraction and multiply the fractions.
Since 5/6 is a repeating decimal, Miguel should convert the fraction 5/6 to a decimal and multiply decimals.
Since 5/6 is a terminating decimal, Miguel should convert 5/6 to a decimal and multiply the decimals.
the correct option is:
"Since 5/6 is a repeating decimal, Miguel should convert the decimal -0.6 to a fraction and multiply the fractions."
Which form would you encourage Miguel to choose?
Miguel wants to do the product below:
-0.6*(5/6)
And he know that to do it, he should convert both numbers to the same form, only that he does not know if he should transform the decimal number into a fraction or the fraction into a decimal.
It is always easier to work with fractions, so the blind answer is to go with the fraction, but let's see why this is the best option.
5/6 written as a decimal will give:
5/6 = 0.833....
It is a repeating decimal number, so taking the exact product would be impossible to do by hand if we used both numbers in decimal form.
While -0.6 written as a fraction is really trivial, just multiply it and divide it by 10, it becomes:
-0.6 = -6/10
Then the product is:
(-6/10)*(5/6) = -5/10 = -1/2
Then the correct option is:
"Since 5/6 is a repeating decimal, Miguel should convert the decimal -0.6 to a fraction and multiply the fractions."

The first three terms of the number sequence are 1, 1/8, and 1/27. And the tenth term of this sequence is 1/1000.
We have been given the nth value of a number sequence that is,
aₙ = n⁻³
We can find the terms by replacing n with required values.
Thus the first term , a₁ = (1)⁻³

Second term, a₂ = (2)⁻³
= 1/8
Third term, a₃ = (3)⁻³
= 1/27
Tenth term, a₁₀ = (10)⁻³
