Step-by-step explanation:
(2+m)/2 = 5
2(2+m)/2 = 5 x 2
2+m = 10
m = 10 - 2
m = 8
(-6+n)/2 = 0
2(-6+n)/2 = 2 x 0
-6 + n = 0
n = 6
(-8+x)/2 = -3
2(-8+x)/2 = -3 * 2
-8 + x = -6
x = -6 + 8
x = 2
(-2+y)/2 = 6
2(-2+y)/2 = 6 * 2
-2 + y = 12
y = 12 + 2

Freud is not a stage theorist
Freud is a stage theorist
Freud is a stage theorist. Sigmund Freud, the renowned Austrian neurologist and psychoanalyst, is widely recognized as one of the pioneers in the field of psychoanalysis.
He proposed a developmental theory that included psychosexual stages of development. According to Freud, human development progresses through distinct stages, each characterized by a specific focus on different erogenous zones. These stages include the oral stage, stage, phallic stage, latency stage, and genital stage. Freud believed that the way individuals navigate these stages influences their personality and psychological well-being in adulthood.
Although Freud's stage theory has been critiqued and modified over time, his ideas regarding the importance of early childhood experiences and unconscious processes have had a profound impact on psychology and continue to shape our understanding of human development.

[-/2 Points] DETAILS HARMATHAP12 12.4.006. MY NOTES Find the cost of producing 30 units (to the nearest dollar). $ 3 PRACTICE ANOTHER Cost, revenue, and profit are in dollars and x is the number of units. If the marginal cost for producing a product is MC = 86-4e-0.01x, with a fixed cost of $8,200, find the total cost function. C(x) #
The cost function for producing x units is C(x) = 0.01x^2 - 86x + 8,200.
To find the total cost function, we need to calculate the sum of the fixed cost and the marginal cost multiplied by the number of units produced. The fixed cost is given as $8,200.
The marginal cost function is MC = 86 - 4e^(-0.01x). This equation represents the additional cost incurred for producing each additional unit. It is a decreasing exponential function, which means that as the number of units produced increases, the marginal cost decreases.
To obtain the total cost function, we multiply the marginal cost by the number of units produced and add it to the fixed cost:
C(x) = 86x - 4e^(-0.01x) * x + 8,200.
Simplifying the equation, we get:
C(x) = 86x - 0.04x * e^(-0.01x) + 8,200.
This equation represents the total cost of producing x units, taking into account both the fixed cost and the varying marginal cost based on the number of units produced.
Learn more about the calculation of the total cost function in economics and how it incorporates fixed costs and marginal costs to determine the overall cost of production. #SPJ11
The total cost function is C(x) = 8200 + 86x - 4e^(-0.01x).
The total cost function is determined by adding the fixed cost of $8,200 to the marginal cost of producing x units. The marginal cost function is given as MC = 86 - 4e^(-0.01x). The term "MC" represents the marginal cost, which is the additional cost incurred for producing one additional unit. The formula for marginal cost indicates that the cost decreases exponentially as the number of units increases. The term "e" represents Euler's number (approximately 2.71828), and the exponent in the formula ensures the exponential decrease in cost.
To find the total cost, we add the fixed cost of $8,200 to the marginal cost. This gives us the total cost function C(x) = 8200 + 86x - 4e^(-0.01x). This equation allows us to calculate the total cost for any given number of units produced.

Answer:
3⁰ = 1
x⁰ = 1
Step-by-step explanation:
You want powers of 3 filled in your table from an exponent of 4 down to an exponent of 0.
Powers of 33⁴ = 3·3·3·3 = 81 . . . . . . 3 is a factor 4 times
3³ = 3·3·3 = 27 . . . . . . . 3 is a factor 3 times
Each row of the table has 3 being a factor of 3^x one fewer times, so each value of 3^x is 1/3 of the previous value.
The last two rows of the table are ...
3¹ = 3
3⁰ = 1
See the attachment for the whole table.
In general, the meaning of x⁰ is ...
x⁰ = 1

Additional comment
In algebra, 0⁰ = 1 is the usual definition. In some contexts (mathematical analysis, calculus), it may be "undefined."

measurement for the length of the 6th leaf?
A) 13.1 cm
B) 13.3 cm
C) 13.4 cm
D) 13.7 cm
The mean measurement is the average value of the leaves
The possible measurement of the 6th leaf is 13.3
How to determine the possible value of the 6th sampleThe dataset is given as:
14.2, 13.8, 12.6, 13.4 and 11.5
Sort the data elements
11.5, 12.6, 13.4, 13.8 and 14.2
Calculate the mean
\(\bar x = \frac{11.5 + 12.6 + 13.4 + 13.8 + 14.2}{5}\)
\(\bar x = \frac{65.5}{5}\)
\(\bar x = 13.1\)
So the mean is 13.1 and the median is 13.4
For the mean to increase, the 6th dataset must be greater than 13.1.
For the median to decrease, the 6th dataset must be less than 13.4
From the list of given options, the element that satisfy the above highlights is 13.3

Step-by-step explanation:
the measure of ∠1 is 50 degrees. what is the measure of ∠6 ?
If the measure of angle 1 is 50° then the measure of angle 2 is 30°.
We know that line l ∥ line m and line p is the transversal.
Let's label the diagram as follows.
Now, by the vertically opposite angles theorem,
we have angle 1 = ∠TPQ = 50°
now ∠P and ∠Q form interior angles,
Hence, by the interior angles theorem, we have
∠P + ∠Q = 180°
The sum of the interior angles of the angles formed by the transversal is 180°.
50° + ∠Q = 180°
subtracting 50° on both sides we get,
∠Q = 180° - 50°
∠Q = 30°
Hence, the measure of angle 2 is 30°.

Rolling a 3 or rolling an odd number on a six sided die. Is it mutually exclusive or non-mutually exclusive? Give one reason.
Answer:
Non-mutually exclusive
Step-by-step explanation:
both events can happen simultaneously... 3 is an odd number, events A and B have a common outcome.
It would be mutually exclusive if event A was rolling a 4 and event B was rolling an odd number.
===================================================
Explanation:
Ask yourself "is it possible to get a 3 and an odd number at the same time?"
The answer is "yes, because 3 is an odd number"
This is why they are non-mutually exclusive.
Mutually exclusive events cannot happen at the same time. In terms of a venn diagram, mutually exclusive events would be represented by two circles that do not overlap. The overlapping region is where the two events happen at the same time. An example of mutually exclusive events would be flipping a single coin to land on heads and tails at the same time.

Lucia draws a square and plots the center of the square, She claims that any rotation about

Which statement best describes Lucia's claim?
A. Lucia's claim is correct since any rotation that carries a square onto itself is a multiple of 45°,
B. Lucia's claim is correct since any rotation that is a multiple of 45° carries a square onto itself
C. Lucia's claim is incorrect since not all rotations that carry a square onto itself are multiples of 45,
D. Lucia's claim is incorrect since not all rotations that are multiples of 45° carry a square onto itself
Answer:
The 2 si right
Step-by-step explanation:
We want to study the symmetry of a square and which rotations carry the square into itself.
We will see that the correct option is the last one:
Not all rotations of multiples of 45° carry the square into itself.
Here we have the claim:
" any rotation about the center of the square that is a multiple of 45° will carry the square onto itself"
And we want to see if this is true or not.
What we can try to do, is find a counterexample to see if this is false.
Let's draw a square, then make a point in the center of it, and draw a segment between the center and the right side.
Now rotate that segment around the center of the square (and along with it, the whole square) by 45°.
(note that 45° is a multiple of 45°).
Doing this, you will see that this rotation does not rotate the square into itself.
So the correct option is D, not all rotations of 45° rotate the square into itself. While rotations of 90°, 180°, 270°, etc... will map the square into itself, we just found an example of a rotation of a multiple of 45° that does not do it.

The given function is f(x) = x^2 + 8x - 6.
2: Apply the power rule.
Differentiate each term of the function separately.
The derivative of x^2 is 2x.
The derivative of 8x is 8.
The derivative of -6 is 0 (constant term).

Combine the derivatives obtained in step 2.
So, f'(x) = 2x + 8.
4: Evaluate f'(1), f'(2), and f'(3).
Substitute x = 1, 2, and 3 into the derived equation to identify the respective values.
f'(1) = 2(1) + 8 = 10.

nicotine patches are often used to help smokers quit. does adding antidepressants to the nicotine patches help? a randomized double-blind experiment assigned 230 to receive a patch that includes the antidepression drug bupropion and 246 smokers who wanted to stop to receive regular nicotine patches. after a year, 98 in the patch
We reject the null hypothesis and conclude that adding bupropion to nicotine patches is associated with a higher quit rate than using regular nicotine patches alone.
However, note that this conclusion is based on a hypothetical quit rate for the bupropion patch group, and the actual quit rate may be different.
To determine whether adding antidepressants to nicotine patches helps smokers quit, we can compare the quit rates of the two groups using statistical analysis.
Let p1 be the quit rate for the group receiving the patch with bupropion and p2 be the quit rate for the group receiving regular nicotine patches.
The null hypothesis is that there is no difference in quit rates between the two groups: p1 - p2 = 0.
The alternative hypothesis is that the quit rate for the group receiving the patch with bupropion is higher:
p1 > p2.
We can use a one-tailed z-test to test this hypothesis, since we are interested in whether the quit rate for the bupropion patch group is higher than the regular patch group.
The test statistic is:
\(z = (p1 - p2) / \sqrt{(p*(1-p)*(1/n1 + 1/n2))}\)
where p = (x1 + x2) / (n1 + n2) is the pooled proportion of smokers who quit, x1 and x2 are the number of smokers who quit in each group, and n1 and n2 are the sample sizes.
From the given information, we know that 98 out of 246 smokers who received regular nicotine patches quit after a year, so x2 = 98 and n2 = 246.
We don't have information about the number of smokers who quit in the bupropion patch group, so we will assume a hypothetical quit rate of 60%, or x1 = 0.6*230 = 138 and n1 = 230.
The pooled proportion is:
p = (x1 + x2) / (n1 + n2) = (138 + 98) / (230 + 246) = 0.415
The standard error of the difference in proportions is:
\(SE = \sqrt{(p*(1-p)(1/n1 + 1/n2)}\)
\(= \sqrt{(0.415(1-0.415)*(1/230 + 1/246)}\)
≈ 0.053.
The z-score is:
z = (p1 - p2) / SE
= (0.6 - 98/246) / 0.053
≈ -6.22
Using a standard normal distribution table or calculator, we can find that the p-value is very small, much smaller than the conventional alpha level of 0.05.

D) the proportion of data items with values more than the upper limit of each class
A cumulative relative frequency distribution shows option (A) the proportion of data items with values less than the upper limit of each class
A cumulative relative frequency distribution shows the proportion of data items with values less than or equal to the upper limit of each class. It provides a cumulative summary of the data distribution by adding up the frequencies or proportions of all preceding classes.
To construct a cumulative relative frequency distribution, you start with the lowest class and calculate the relative frequency (proportion) of data items in that class. Then, for each subsequent class, you add the relative frequency of that class to the cumulative relative frequency from the previous class. This cumulative value represents the proportion of data items with values less than or equal to the upper limit of the current class.
In essence, a cumulative relative frequency distribution allows you to track the accumulation of data values as you move through the classes, giving insights into the overall distribution and the proportion of data items falling below specific values.
