(6e−3f−4)⋅2=left parenthesis, 6, e, minus, 3, f, minus, 4, right parenthesis, dot, 2, equals
The final result of the expression (6e−3f−4)⋅2 is e3f−8.
The calculation is as follows: (6e−3f−4)⋅2 = (6e-3f-4)*2. In order to calculate this expression, it is necessary to use the Order of Operations. The Order of Operations is a set of rules that determine the order in which operations should be performed when evaluating an expression. First, any parentheses need to be evaluated. In this expression, there are parentheses surrounding 6e−3f−4. This means that any operations within the parentheses should be done first. Inside the parentheses, there is an exponent, e−3f, and a subtraction, 4. Exponents should be done first, so e−3f should be evaluated first. This is equivalent to e multiplied by e multiplied by e, multiplied by f, which is equal to e3f. Then, 4 should be subtracted from e3f, which is equal to e3f−4. After the parentheses have been evaluated, the remaining multiplication should be done. This is equivalent to (e3f−4)*2, which is equal to e3f−8.

What is subtraction?Subtraction is one of the four arithmetic operation along with addition, multiplication and division. Subtraction is an operation that represents removal of objects from a collection. For example, in the adjacent picture, there are 5 − 2 peaches, this means that 5 peaches with 2 taken away, resulting in a total of 3 peaches.
The frame is place in the Middle of the wall. The space left after the frame is hanged is calculated as 48inches - 17.5 inches = 30.5 inches.
Since the frame is at the middle of the wall , the space (x) at both sides is equal

Town L is 13 miles due south of town N. Town B is due east of town L and S 65° E from town N. How far is town L from town B? (Round your answer to the nearest whole number.)
The distance between Town L and Town B is 9 miles, calculated using the distance formula and Law of Sines.
First, let's calculate the distance between Town N and Town L. We know that Town L is 13 miles due south of Town N. We can calculate this distance using trigonometry. We can use the distance formula, \(d = sqrt((x2 - x1)^2 + (y2 - y1)^2)\), to calculate the distance. The x-coordinates for Town N and Town L are both 0, since Town L is due south of Town N. The y-coordinate for Town N is 0 and the y-coordinate for Town L is -13 miles. Plugging these values into the distance formula, we get
\(d = sqrt((0 - 0)^2 + (-13 - 0)^2) = 13 miles.\)
Now, let's calculate the distance between Town L and Town B. We know that Town B is due east of Town L and S 65° E from Town N. We can use the Law of Sines to calculate the angle between Town L and Town B.
The Law of Sines states that a/sin(A) = b/sin(B) = c/sin(C), where a, b, and c are the sides of a triangle and A, B, and C are the angles. We know that Town B is due east of Town L, so the angle between Town L and Town B is 90°. We also know that Town B is S 65° E from Town N, so the angle between Town N and Town B is 65°. Plugging these values into the Law of Sines, we get
13/sin(90) = x/sin(65), where x is the distance between Town L and Town B. Solving for x, we get
x = 13sin(65)/sin(90) = 8.9 miles.
Rounding to the nearest whole number, the distance between Town L and Town B is 9 miles.

if a student answers each question at random, what is the probability that they will answer at least 14 questions correctly?
the probability that a student, answering each question at random, will answer at least 14 questions correctly is approximately 0.0000039 rounded to seven decimal places.
To calculate the probability that a student, answering each question at random, will answer at least 14 questions correctly, we can use the binomial probability formula.
The probability of answering a question correctly by random chance is 1 out of 5, which can be expressed as 1/5 or 0.2.
Let's denote:
n = number of trials (number of questions) = 20
p = probability of success (probability of answering a question correctly) = 0.2
x = number of successful outcomes (number of questions answered correctly)
We want to calculate the probability of answering at least 14 questions correctly, which means we need to find the probability of getting 14, 15, 16, 17, 18, 19, or 20 questions correct.
Using the binomial probability formula, we can calculate the probability for each case and sum them up:
P(X ≥ 14) = P(X = 14) + P(X = 15) + P(X = 16) + P(X = 17) + P(X = 18) + P(X = 19) + P(X = 20)
P(X = k) = (n choose k) * \(p^k * (1 - p)^{(n - k)\)
Using this formula for each value of k and adding them up, we find:
P(X ≥ 14) ≈ 0.0000039
Therefore, the probability that a student, answering each question at random, will answer at least 14 questions correctly is approximately 0.0000039 rounded to seven decimal places.

Answer:
x = 11
z = 86
Step-by-step explanation:
8x + 6 and 10x-16 are vertical angles
Vertical angles are pairs of angles that are opposite each other and have the same vertex, or point of intersection. They are formed when two lines intersect at a point, and are always congruent, or of equal measure.
To solve this equation, we need to isolate the variable x on one side of the equation. To do this, we can start by subtracting 6 from both sides of the equation:
8x + 6 - 6 = 10x - 16 - 6
8x = 10x - 22
Now we can subtract 8x from both sides of the equation:
8x - 8x = 10x - 22 - 8x
0 = 2x - 22
To solve for x, we can add 22 to both sides of the equation:
0 + 22 = 2x - 22 + 22
22 = 2x
Finally, we can divide both sides of the equation by 2 to find the value of x: 22 / 2 = 2x / 2
x = 11
Therefore, the solution to the equation is x = 11.
Now that we have x, z is a supplementary angle to 8x + 6 (or you could do 10x - 16)
Supplementary angles are pairs of angles that add up to 180 degrees. They are formed when two lines intersect at a point, and the angles formed at the intersection are supplementary.
First plug in x, 8x + 6 = 8(11) + 6 = 88 + 6 = 94
180 - 94 = z
z = 86

We have,
Probability is a measure of how likely an event is to occur.
It is a way of quantifying uncertainty and making predictions based on incomplete information.
For example,
When we toss a fair coin, there are two possible outcomes: heads or tails. Since the coin is fair, each outcome has an equal chance of occurring, so the probability of getting heads is 1/2 or 50%, and the probability of getting tails is also 1/2 or 50%.
Another example of probability is when we roll a six-sided die.
There are six possible outcomes, each of which has an equal chance of occurring.
Therefore, the probability of rolling a specific number, say 4, is 1/6 or approximately 17%.

A line has a slope of
2/7 and passes through the point (7,0). Write its equation in slope-intercept form.
Answer: The slope-intercept form of the equation of a line is y = mx + b, where "m" is the slope and "b" is the y-intercept.
We know that the slope of the line is 2/7. We can also find the y-intercept by plugging in the coordinates of the given point (7,0) and solving for "b".
0 = (2/7) * 7 + b
0 = 2 + b
b = -2
So the equation of the line in slope-intercept form is:
y = (2/7)x - 2
Step-by-step explanation:
Answer: \(y=\frac{2}{7}x-7\)
Step-by-step explanation:
m=slope=2/7
point(7,0)
put into point-slope formula
\((y-y_{1})=m(x-x_{1)}\) where \((x_{1} ,y_{1)} =(0,7)\)
\(y-7=\frac{2}{7}(x-0)\) now put into slope- intercept(y=mx+b) form by simplifying, 0 goes away, and add 7 to both sides
\(y=\frac{2}{7}x-7\) b is your y-intercept, where it hits y-axis

The gross earnings are $225, federal taxes are $40.50, state taxes are $9, social security deduction is $15.86, total deductions are $65.36, and the net pay is $159.64.
The gross earnings are determined by multiplying the pay rate by the number of hours worked.
Federal taxes, state taxes, and social security deductions are calculated by applying the respective tax rates to the gross earnings.
Total deductions are the sum of federal taxes, state taxes, and social security deductions.
Net pay is obtained by subtracting the total deductions from the gross earnings.
To calculate the gross earnings, we multiply the pay rate of $7.50 by the number of hours worked, which is 30.
Therefore, the gross earnings are $7.50 * 30 = $225.
Next, we can calculate the federal taxes by applying the tax rate of 18% to the gross earnings.
The federal taxes amount to 18% * $225 = $40.50.
Similarly, the state taxes can be calculated by applying the tax rate of 4% to the gross earnings.
The state taxes amount to 4% * $225 = $9.
To determine the social security deduction, we apply the tax rate of 7.05% to the gross earnings.
The social security deduction amounts to 7.05% * $225 = $15.86.
The total deductions are the sum of the federal taxes, state taxes, and social security deduction.
Thus, the total deductions are $40.50 + $9 + $15.86 = $65.36.
Finally, to calculate the net pay, we subtract the total deductions from the gross earnings.
Therefore, the net pay is $225 - $65.36 = $159.64.
In conclusion, the gross earnings are $225, federal taxes are $40.50, state taxes are $9, social security deduction is $15.86, total deductions are $65.36, and the net pay is $159.64.

Are 90 degrees (clockwise) and -270 degrees (counter clockwise) coterminal? WHY or why not?
Yes, 90 degrees (clockwise) and -270 degrees (counterclockwise) are coterminal angles.
What are coterminal angles ?Two angles are coterminal if they share the same terminal side when drawn in standard position. In other words, coterminal angles differ by an integer multiple of 360 degrees.
To see if 90 degrees and -270 degrees are coterminal, we can add 360 degrees to the smaller angle (-270 degrees) and see if we get the other angle:
-270 + 360 = 90
Since we obtain 90 degrees after adding 360 degrees to -270 degrees, these two angles are coterminal. They share the same terminal side in standard position, even though their rotations have different directions (clockwise and counterclockwise).
