Step-by-step explanation:
Which of the following expressions are equal to -8/11 - 3/4 - 1/4
In the expressions that we are given, we can note that there is a negative in all of them. This means that we can factor out the negative.
With the negative factored out, it will look like this: [tex]-(\frac{8}{11} + \frac{3}{4} + \frac{1}{4} )[/tex]
The reasoning for this is because you distribute the negative to each term. For example 8/11 is a term, and so is 3/4, and 1/4. So our first answer is D.
Another way we can do this is by combining like terms. We see that in the denominator for -3/4 and -1/4 they both share 4. We can combine it so it becomes -4/4 or -1. It would be E.
The third way we can do this is by rewriting it. Answer A rewrites it so that it is + -, effectively just -. This allows us to treat the equation as if it were the original one.
Hopefully this helps you out, brainliest would help me out.

Part 1
In airline applications, failure of a component can result in catastrophe. As a result, many airline components utilize something called triple modular redundancy. This means that a critical component has two backup components that may be utilized should the initial component fail. Suppose a certain critical airline component has a probability of failure of 0.0056 and the system that utilizes the component is part of a triple modular redundancy.
(a) Assuming each component's failure/success is independent of the others, what is the probability all three components fail, resulting in disaster for the flight?
(b) What is the probability at least one of the components does not fail?
The probability that all three components fail is 1.756 × 10⁻⁷. The probability of at least one of the components does not fail 0.9999998244.
What is a Probability?Probability is the likelihood for an event to occur. In a given statistical distribution, the probability explains the range of values and probabilities that a randomized variable could have.
From the given information;
Assuming each component's failure/success is independent of the others: the probability that all three components fail is:
P(three components fail) = (0.0056)^3
P(three components fail) = 1.756 × 10⁻⁷
The probability that at least one does not fail is:
P(at least one does not fail) = 1 - P(all three components fail)
P(at least one does not fail) = 1 - 1.756 × 10⁻⁷
P(at least one does not fail) = 0.9999998244

determine whether each pair of lines is perpendicular parallel or neither
Answer:
1st set of equations - parallel
2nd set - perpendicular
3rd set - neither
Step-by-step explanation:
First set:
simplify the equation for line 1 by dividing by -4: y = 0.5x + 1
simplify the equation for line 1 by dividing by -6: y = 0.5x - 1.5
Both have the same slope: 0.5 so the lines are parallel.
Second set:
simplify the equation for line 1 by dividing by 3: y = -2/3x + 4
simplify the equation for line 1 by dividing by -4: y = 3/2x - 7/4
-2/3 * 3/2 = -1, so the lines are perpendicular
Third set
simplify the equation for line 1 by dividing by 1/2: y = -2x+4
simplify the equation for line 1 by dividing by 2: y = -1/4x +2
-2x+4=-0.25x+2
-2x+0.25x=2-4
-1.75x=-2
x=1.14
y=-2(1.14)+4 = 1.7143. So there is an intersection point
The pair of lines 2x - 4y = -4 & 3x - 6y = 9, 2x + 3y = 12 & and 6x - 4y = 7, and x + (1/2)y = 2 & (1/2)x + 2y = 4 will be parallel lines, perpendicular lines, and neither parallel nor perpendicular, respectively.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The pair of lines is given as,
2x - 4y = -4 ⇒ y = (1/2)x + 1
3x - 6y = 9 ⇒ y = (1/2)x - 3/2
The pair of lines are parallel to each other because the slope is equal.
2x + 3y = 12 ⇒ y = -(2/3)x + 4
6x - 4y = 7 ⇒ y = (3/2) x - 7/4
The pair of lines are parallel to each other because the product of slopes is -1.
x + (1/2)y = 2 ⇒ 2x + y = 4
(1/2)x + 2y = 4 ⇒ 2x + 4y = 8
The pair of lines are neither parallel nor perpendicular to each other.

Answer:
The answer is either 30 degrees or 36 degrees.
You need a protractor to measure it.
Most probably, the answer is 30 degrees.
BUT PLEASE MEASURE THE ANGLE WITH A PROTRACTOR!
Answer:
d. 60°
Step-by-step explanation:
Since the clock is a full circle, it has a degree span of 360°.
∴ every 5-min interval on the clock
= 360° ÷ 12 five min intervals
= 30°
∴ acute angle formed by clock in figure

[tex]\textsf{Let }\:u=\sin (2x) \implies \dfrac{\text{d}u}{\text{d}x}=2 \cos (2x)[/tex]
[tex]\textsf{Let }\:\dfrac{\text{d}v}{\text{d}x}=-e^{-2x} \implies v=\dfrac{1}{2}e^{-2x}[/tex]
Substituting the defined parts into the formula:
[tex]\begin{aligned}\implies \displaystyle -\int e^{-2x}\sin(2x)\:\text{d}x & =\dfrac{1}{2}e^{-2x}\sin (2x)- \int \dfrac{1}{2}e^{-2x} \cdot 2 \cos (2x)\:\text{d}x\\\\& =\dfrac{1}{2}e^{-2x}\sin (2x)- \int e^{-2x} \cos (2x)\:\text{d}x\end{aligned}[/tex]
[tex]\displaystyle \textsf{For }\:-\int e^{-2x} \cos (2x)\:\text{d}x \quad \textsf{integrate by parts}:[/tex]

Therefore:
[tex]\implies \displaystyle -\int e^{-2x}\sin(2x)\:\text{d}x =\dfrac{1}{2}e^{-2x}\sin (2x) +\dfrac{1}{2}e^{-2x}\cos(2x)+ \int e^{-2x} \sin(2x)\:\text{d}x[/tex]

Divide both sides by 2:
[tex]\implies \displaystyle -\int e^{-2x}\sin(2x)\:\text{d}x =\dfrac{1}{4}e^{-2x}\sin (2x) +\dfrac{1}{4}e^{-2x}\cos(2x)+\text{C}[/tex]
Rewrite in the same format as the given integral:
[tex]\displaystyle \implies - \int \dfrac{\sin(2x)}{e^{2x}}\: \text{d}x=\dfrac{\sin(2x)}{4e^{2x}}+\dfrac{\cos(2x)}{4e^{2x}}+\text{C}[/tex]

The changes in account balances for Elder Company for 2021 are as follows:
Assets $ 480,000 debit
Common stock 250,000 credit
Liabilities 160,000 credit
Paid-in capital—excess of par 30,000 credit
Assuming the only changes in retained earnings in 2021 were for net income and a $50,000 dividend, what was net income for 2021?
The changes in account balances for Elder Company for 2021 are net income will be $160000
We have given debt common stock = $680000
Credit liabilities = 350000
Credit paid in capital = 190000
And an excess of par 30,000 credit Assuming the only changes in retained earnings
So 680000 = 350000+190000+30000+ retained earning
What is the net income?Net income is an entity's income minus the cost of goods sold, expenses, depreciation and amortization, interest, and taxes for an accounting period.
So retained earning = $110000
Dividend paid = $50000
So Net income = dividend paid + retained earning
Net income = $110000+$50000
Net income = $160000

Om42 = 50°
Om42 = 120°
Om22 130°
Answer:
Option 2angle 2 = 7x + 1 ( vertically opposite angles)
7x + 1 + 18x + 4 = 180° ( forming linear pair).
7x + 18x + 4 +1 = 180°
25x + 5 = 180°
25x = 180 - 5
25x = 175
x = 7°
angle 2 = 7(7)+ 1
= 50°
The measure of angle ∠2 of the parallel lines is ∠2 = 50°
What are angles in parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line. The intersecting line is known as transversal line.
We can conclude three factors determining parallel lines ,
Alternate angles are equal
Corresponding angles are equal
Co-interior angles add up to 180°
Given data ,
Let the parallel lines be b and c
Now , the measure of ∠1 + ∠2 = 180° ( angles on the same line )
And , the measure of ∠2 = ( 7x + 1 )° ( alternate angles are equal )
So , ( 7x + 1 ) + ( 18x + 4 ) = 180° ( angles on the same line )
On simplifying , we get
25x + 5 = 180
25x = 175
x = 7
So , the measure of angle ∠2 = ( 7 ( 7 ) + 1 )
The measure of angle ∠2 = 50°
Hence , the angle is ∠2 = 50°

How to evaluate the piece wise function?The function is given as:

To calculate g(-0.5), we make use of the domain -1.5 < x ≤ -0.5
At this domain;
g(x) = -1
So, the value of g(-0.5) is
g(-0.5) = -1
To calculate g(0.3), we make use of the domain -0.5 < x 0.5
At this domain;
g(x) = 0
So, the value of g(0.3) is
g(0.3) = 0
To calculate g(0.5), we make use of the domain 0.5 ≤ x 1.5
At this domain;
g(x) = 1
So, the value of g(0.5) is
