Answer:

Step-by-step explanation:

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

\(y=1+2x\implies y=\stackrel{\stackrel{m}{\downarrow }}{2}x+1\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill\)

\(\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{2\implies \cfrac{2}{1}} ~\hfill \stackrel{reciprocal}{\cfrac{1}{2}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{1}{2}}}\)

so we're really looking for the equation of a line whose slope is -1/2 and that it passes through (4 , -4)

\((\stackrel{x_1}{4}~,~\stackrel{y_1}{-4})\hspace{10em} \stackrel{slope}{m} ~=~ - \cfrac{1}{2} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-4)}=\stackrel{m}{- \cfrac{1}{2}}(x-\stackrel{x_1}{4}) \implies y +4= -\cfrac{1}{2} (x -4) \\\\\\ y+4=-\cfrac{1}{2}x+2\implies {\Large \begin{array}{llll} y=-\cfrac{1}{2}x-2 \end{array}}\)

The setting of the machine should be no more than 6.135 milliliters per can of paint to ensure that no more than 2.5% of the cans of paint will be unacceptable.

A continuous probability distribution known as the normal distribution is frequently used to simulate symmetric and bell-shaped real-world phenomena. The mean and the standard deviation are the two factors that define it. Because of its numerous characteristics and uses, the normal distribution is significant in statistics and data analysis. The assumption that the data are normally distributed or may be approximated by a normal distribution is made by many statistical tests and confidence ranges, for instance.

Let us suppose the amount of dye discharged = X.

Thus, X ~ N(μ, σ).

Now, for μ such that no more than 2.5%:

P(X > 6.4) ≤ 0.025

Using the z-score we have:

Z = (X - μ) / σ

P(X > 6.4) = P((X - μ) / σ > (6.4 - μ) / σ) = P(Z > (6.4 - μ) / σ)

(6.4 - μ) / 0.1342 > 1.96

μ < 6.4 - 1.96(0.1342) = 6.135

Hence, the setting of the machine should be no more than 6.135 milliliters per can of paint to ensure that no more than 2.5% of the cans of paint will be unacceptable.

The point where the lines carrying the elevations intersect is the orthocenter of a triangle.

A polygon with three edges and three vertices is called a triangle.

It is one of the fundamental geometric shapes.

The symbol for a triangle having vertices A, B, and C is ABC.

In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space).

In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle.

All triangles are enclosed in a single plane if all of the geometry is the Euclidean plane, however, this is no longer true in higher-dimensional Euclidean spaces.

The orthocenter of a triangle is the intersection of the lines that carry the elevations.

Therefore, the point where the lines carrying the elevations intersect is the orthocenter of a triangle.

The construction of a triangle is an integral part of bisecting an angle, and understanding the properties of triangles is crucial for any geometric construction.

To bisect an angle, we first draw a triangle with the angle to be bisected as one of its vertices. Then, we construct an angle with the same vertex, which is greater than half the angle we want to bisect. Next, we draw a circle with the vertex of the angle to be bisected as its center and passing through the other two vertices of the triangle. The point where the circle intersects the angle we drew earlier is our bisected angle.

Moreover, it is essential to understand the underlying geometric principles and concepts behind the construction. The use of technology should complement our understanding and facilitate the construction process rather than replace it. Therefore, it is recommended to have a sound understanding of the construction steps and the properties of triangles before using technology.

In conclusion, the construction of bisecting an angle using technology is an efficient and accurate method. Still, it is essential to have a solid understanding of the underlying geometric concepts and principles to ensure the correctness of the construction.

Answer:

The correct answer is:

It is a continuous random variable (C)

Step-by-step explanation:

Continuous Random Variables are variables that do not take on a distinct value. They take on values that are a range of different possibilities to infinity. In continuous random variables, the values cannot be counted. In this example, the time it takes for a light bulb to burn out can be any rational number which is greater than 0, up to infinity; for instance, it can be 24 hours, 24.5 hours, 30.8 hours, 51.2 hours etc. There is an infinite possibility of the time it takes for the bulb to burn out.

Discrete Random Variables are ones in which the variables take on distinct values and nothing in between. Here, the outcomes can be counted. For example if a coin is tossed, there are only two possibilities which can be the outcome and that is either head, or tail. The number of possible outcome is 2, and there is nothing inbetween head or tail.

Answer: -4

Step-by-step explanation:

the slope is -4 because when x goes down by 2, y goes down by -8, so the y intercept is -4 because when x=-1 y=0 so if you go down 4 and over 1, you get the point x=0 and y=-4

As from question asking the probability of A be the event "the outcome is a divisor of 4".

Annalise is correct because the outputs are closest when x = 1.35

Step-by-step explanation:

The solution to the equation 1/(x-1) = x² + 1 means the one x value that will make both sides equal. If we look at the table, notice how when x = 1.35, f(x) values are closest to each other for both equations, signifying that x = 1.35 is approximately the solution. Thus, Annalise is correct.

Answer:

it took her 54 mins to finish her walk.

Step-by-step explanation:

Given;

total distance walked by Katie, d = ⁵/₆

time taken to walk ¹/₆ mile = 10 mins

break time = 1 min

There are five ¹/₆ mile in the total distance which is ⁵/₆ miles.

Time for the first  ¹/₆ mile  = 10 mins +

                    break time = 1 min

Time for the second  ¹/₆ mile  = 10 mins +

                     break time = 1 min  

Time for the third  ¹/₆ mile  = 10 mins +

                     break time = 1 min  

Time for the fourth  ¹/₆ mile  = 10 mins +

                     break time = 1 min  

Time for the fifth  ¹/₆ mile  = 10 mins

Total time = 5 (10 mins)  + 4 (1 min)

                 = 50 mins + 4mins

                = 54 mins

Therefore, it took her 54 mins to finish her walk.

The postfix expression of "7+5-3*2(6*7)/4" is "7 5 + 3 2 * 6 7 * 2 * - 4 /". Evaluating the postfix expression gives the result of the expression. The prefix expression for the given infix expression is "/ - + 7 5 * 3 * 2 ( * 6 7 ) 4".

To convert the infix expression "7+5-3*2(6*7)/4" into postfix expression, we follow the rules of operator precedence and associativity. The postfix expression is obtained by placing operators after their operands.

The postfix expression for the given infix expression is:

"7 5 + 3 2 * 6 7 * 2 * - 4 /"

To evaluate the postfix expression, we use a stack data structure. We scan the postfix expression from left to right and perform the corresponding operations.

Starting with an empty stack, we encounter the operands "7" and "5". We push them onto the stack. Then we encounter the operator "+", so we pop the last two operands from the stack (5 and 7), perform the addition operation (7 + 5 = 12), and push the result back onto the stack.

We continue this process for the remaining operators and operands in the postfix expression. Finally, after evaluating the entire expression, the result left on the stack is the final answer.

To convert the infix expression into prefix expression, we follow similar rules but scan the expression from right to left. The prefix expression is obtained by placing operators before their operands.

The prefix expression for the given infix expression is:

"/ - + 7 5 * 3 * 2 ( * 6 7 ) 4"

Assuming the interest is compounded semiannually, the interest rate that would be required in order for Brenda to end up with $6,520.02 is 0.68 or 68%.

Mathematically, compound interest can be calculated by using this formula:

A(t) = P(1 + r/n)^{nt}

Where:

Substituting the given parameters into the compound interest formula, we have;

6,520.02 = 4,848(1 + r/2)^{2 × 6}

1.34488861386 = (1 + 0.5r)^{12}

1.34488861386 = (1.5r)^{12}

Taking the 12th root of both sides of the equation, we have:

1.02499998664 = 1.5r

r = 1.02499998664/1.5

r = 0.68 or 68%.
