Subtract the sum of -52 and - 638 from the sum of - 29 and 303 the value is
The solution of the expression is 964.
To start solving this problem, let's find the sum of -29 and 303. The sum of two numbers is the result when you add them together. So,
-29 + 303 = 274
The sum of -29 and 303 is 274.
Now, let's find the sum of -52 and -638. To add two negative numbers, you just add their absolute values and put a negative sign in front of the result. So,
-52 + (-638) = -690
The sum of -52 and -638 is -690.
Finally, the problem asks us to subtract the sum of -52 and -638 from the sum of -29 and 303. To subtract one sum from another, we just subtract the second sum from the first. So,
( -29 + 303 ) - ( -52 + -638 )
We can simplify the expression by rearranging the terms:
274 - (-690)
When we subtract a negative number, it's the same as adding its absolute value. So,
274 + 690 = 964

Mary needs $9000 in 9 years. What amount can she deposit in a sinking fund at the end of each quarter at 4% interest compounded quarterly so she will have her $9000?
Please serious answers only
Mary needs to deposit $282.44 at the end of each quarter into a sinking fund that earns 4% interest compounded quarterly in order to have $9,000 in 9 years.
what is deposit ?
In the context of finance, a "deposit" refers to the act of placing money or funds into a bank account, investment account, or other financial account. A deposit can also refer to the initial payment made to secure or initiate a purchase
In the given question,
To calculate the sinking fund payment that Mary needs to make at the end of each quarter, we can use the formula for the future value of an annuity:
FV = PMT x [(1 + r/n)ⁿᵇ - 1]/(r/n)
Where:
FV = future value (the amount Mary needs to accumulate, which is $9,000 in this case)
PMT = payment per period (what Mary needs to find)
r = annual interest rate (4% in this case)
n = number of compounding periods per year (4, since interest is compounded quarterly)
t = number of years (9 in this case)
Substituting these values into the formula, we get:
$9,000 = PMT x [(1 + 0.04/4)³⁶ - 1]/(0.04/4)
Simplifying and solving for PMT, we get:
PMT = $9,000 / [(1.01³⁶ - 1)/0.01]
PMT = $9,000 / 31.8422
PMT = $282.44 (rounded to the nearest cent)
Therefore, Mary needs to deposit $282.44 at the end of each quarter into a sinking fund that earns 4% interest compounded quarterly in order to have $9,000 in 9 years.

cara computes the mean and variance for the set 87, 46, 90, 78, and 89. she finds the mean to be 78. her steps for finding the variance are shown below. what is the first error cara made in computing the variance?
If Cara's calculation of the sum of the squared differences i.e. 1370 from the mean is incorrect, that would be the first error she made in computing the variance.
As the steps for finding the variance are not provided, it is difficult to determine the first error Cara made.
However, the formula for calculating the variance is:
Variance = (sum of the squared differences from the mean) / (number of observations)
The first error Cara may have made is in calculating the sum of the squared differences from the mean.
The correct steps to find the variance are:
Find the mean:
Mean = (87 + 46 + 90 + 78 + 89) / 5 = 78
Calculate the differences from the mean for each observation:
87 - 78 = 9
46 - 78 = -32
90 - 78 = 12
78 - 78 = 0
89 - 78 = 11
Square each difference:
[tex]9^2 = 81[/tex]
[tex](-32)^2 = 1024[/tex]
[tex]12^2 = 144[/tex]
[tex]0^2 = 0[/tex]
[tex]11^2 = 121[/tex]
Find the sum of the squared differences:
81 + 1024 + 144 + 0 + 121 = 1370
Divide the sum of squared differences by the number of observations:
Variance = 1370 / 5 = 274.

Nadia is on a 3-ft ladder and sling shots a rubber band toward her friend. The
rubber band, f(x), can be represented by f(x) = -x² + 4x + 3 where x represents the horizontal distance traveled by the rubber band in feet. Write and solve an equation to find the horizontal distance traveled by the rubber band if its height is 0.75 feet.
The horizontal distance traveled by the rubber band is 4.5 feet
How to write and solve an equation to find the horizontal distance traveled by the rubber band?To write and solve an equation to find the horizontal distance traveled by the rubber band if its height is 0.75 feet, substitute f(x) = 0.75 feet into the equation representing the rubber band and solve for x. That is:
f(x) = -x² + 4x + 3
0.75 = -x² + 4x + 3
x² - 4x - 3 + 0.75 = 0
x² - 4x - 2.25 = 0
(x - 9/2)(x + 1/2) = 0 (factorize)
x = 9/2 or x = -1/2
x = 4.5 or x = -0.5
Since distance cannot be negative.
Thus, x = 4.5 feet

a region is bounded by two concentric circles, as shown by the shaded region in the figure above. the radius of the outer circle, r , is increasing at a constant rate of 2 inches per second. the radius of the inner circle, r , is decreasing at a constant rate of 1 inch per second. what is the rate of change, in square inches per second, of the area of the region at the instant when r is 4 inches and r is 3 inches? responses
The rate of change of the area is 20π square inches per second.
How to calculate area of the shaded region?The area of the shaded region can be calculated as the difference between the areas of the outer circle and the inner circle:
A = πr^2 - πr'^2
where r is the radius of the outer circle, r' is the radius of the inner circle, and π is the constant pi.
To find the rate of change of the area, we can take the derivative of both sides of the equation with respect to time t:
dA/dt = d/dt (πr^2) - d/dt (πr'^2)
Using the chain rule, we can express the derivatives in terms of the rates of change of the radii:
dA/dt = 2πr (dr/dt) - 2πr' (dr'/dt)
Substituting the given values at the instant when r=4 inches and r'=3 inches, we have:
dA/dt = 2π(4)(2) - 2π(3)(-1) = 20π
Therefore, the rate of change of the area is 20π square inches per second.

D. Scale vertically by 1/2, reflect over the x-axis, then translate up 1.
The correct answer is option B. Translate 1 to the left, scale vertically by 1/2, then reflect over the y-axis.
What does term "transformation of a graph" means?The process of modifying the shape, location, or features of a graph is often referred to as graph transformation. Graphs are visual representations of mathematical functions or data point connections, often represented on a coordinate plane.
Translations, reflections, rotations, dilations, and other changes to the look of a graph are examples of graph transformations.
For the given problem, Transformation to get the desired result can be carried out as:
Translate '1' to the left: The transformation "x + 1" in "-k(x + 1)" shifts the graph horizontally to the left by 1 unit.Scale vertically by '1/2' : The 1/2 factor in "-k(x + 1)" vertically scales the graph, compressing it vertically.Reflect over the y-axis: The minus sign before "k" in "-k(x + 1)" reflects the graph over the y-axis, flipping it horizontally.Hence, to convert the graph of "y = k(x)" to the graph of "y = -k(x + 1)," the correct sequence of transformations is to translate 1 unit to the left, scale vertically by 1/2, and then reflect across the y-axis, which is option B.

The value of x after executing the last statement is still 10.
After executing the last statement, the value of x is still 10. The snippet of code declares an integer variable x and a pointer variable y that points to the address of x. Then, y is incremented by 1 (which means it now points to the next memory location after x). Finally, the value 100 is assigned to the memory location pointed to by y, which is actually beyond the memory allocated for variable x. This can lead to unexpected behavior, but since the value of x is never modified directly, its value remains unchanged at 10.

Spinner divided evenly into eight sections with three colored blue, one red, two purple, and two yellow. Determine the theoretical probability of the spinner not landing on red, P. 0.125 0.250 0.675 0.875
The theoretical probability of the spinner not landing on red is 0.875.
How to determine the theoretical probability of the spinner not landing on redThe total number of sections on the spinner is 8, out of which only one section is red. Therefore, the probability of the spinner landing on red is:
P(Red) = 1/8
The probability of the spinner not landing on red would be the probability of landing on any other section, which is:
P(Not Red) = 1 - P(Red) = 1 - 1/8 = 7/8
Therefore, the theoretical probability of the spinner not landing on red is 7/8 or 0.875 in decimal form.

$0. 55
$0. 40
$0. 60
$0. 30
The game owner should charge option (a) $0.55 to make it a fair game
To determine how much the game owner should charge to make it a fair game, we need to calculate the average value of each package. We can do this by finding the total value of all the packages and dividing it by the total number of packages.
The total value of the 30 packages worth $.65 each is:
30 x $.65 = $19.50
The total value of the 10 packages worth $.60 each is:
10 x $.60 = $6.00
The total value of the 15 packages worth $.30 each is:
15 x $.30 = $4.50
The total value of all the packages is
$19.50 + $6.00 + $4.50 = $30.00
The total number of packages is
30 + 10 + 15 = 55
The average value of each package is

survey of small businesses with websites found that the average amount spent on a site was $11,000 per year with a standard deviation of $3,000. given a sample of 40 businesses, what is the margin of error if you are to assume a 95% confidence level? (round your answer to two decimal places.)
The margin of error for the 95% confidence level is approximately $873.15.
To calculate the error bars for the 95% confidence level, we need to find the critical value of the z-score from the standard normal distribution table.
Accepting a 95% certainty level, the importance level (α) is 0.05, which implies the certainty level is 1-α = 0.95.
On the off chance that we see the z-score at the 95% certainty level on the standard typical conveyance table, we get an esteem of 1.96.
Then you can use the formula for Tolerance (E).
error bar (E) = z * (standard deviation / sqrt(n))
where:
z = critical value in the standard normal distribution table
standard deviation = $3,000
n=40
Substitute the obtained value.
Error Bar (E) = 1.96 * ($3,000 / sqrt(40))
≈ $873.15
Therefore, the margin of error for the 95% confidence level is approximately $873.15.
