A profit of $1.45 was earned on each bag of oranges sold. (See 13 bags.) Find the profit if all the bags were sold.
Solution:
If a profit of $1.45 was earned on each bag of oranges sold, then the profit, if all 13 bags were sold, would be:
13 x $1.45 = $18.85
so that, the correct answer is:
$18.85
The two points on the graph are given by the linear function f use the two points to find the equation that represents the linear function f. What is f(6)?
The function f(6) has a value of 1./3
How to determine the value of the linear equation?The graph that completes the question is added as an attachment
From the graph, we have the following points
(x, y) = (4, 1) and (1, 2)
We start by calculating the slope of the points using the following slope equation
Slope = (y₂ - y₁)/(x₂ - x₁)
Where x and y are defined above
So, we have
Slope = (2 - 1)/(1 - 4)
Evaluate
Slope = -1/3
At f(6), we have
x = 6
So, the point can be represented as (6, y)
Using the slope formula again, we have
Slope = (y₂ - y₁)/(x₂ - x₁)
Where
(x, y) = (4, 1) and (6, y)
This gives
Slope = (y - 1)/(6 - 4)
Evaluate
Slope = (y - 1)/2
So, we have
(y - 1)/2 = -1/3
Evaluate
y = -2/3 + 1
Evaluate
y = 1/3
Hence, the value of f(6) is 1/3

Find the indicated probability. Round to three decimal places.A machine has 6 identical components which function independently. The probability that a component will fail is 0.3. Themachine will stop working if more than two components fail. Find the probability that the machine will be working.
Answer: 74.43%
Let us first list down the probabilities of the machine working.
First is the probability that none of the components will fail. We can write this probability as:
[tex]P(0)=(1-0.3)^6[/tex]Next, the probability that one of the components will fail. This will give us:
[tex]P(1)=C^1_6(1-0.3)^5(0.3)[/tex]Then, the probability that 2 of the components will fail.
[tex]P(2)=C^2_6(1-0.3)^4(0.3)^2[/tex]Adding all of these probabilities and we will have:
[tex]P=(1-0.3)^6+C^1_6(1-0.3)^5(0.3)+C^2_6(1-0.3)^4(0.3)^2[/tex][tex]P=(0.7)^6+(6)(0.7)^5(0.3)+(15)(0.7)^4(0.3)^2[/tex][tex]P=0.74431\times100=74.43\%[/tex]Therefore, the probability that the machine will be working would be 74.43%.

vera wants to prove that any rectangle is also a parallelogram
We are given a rectangle ABCD
Recall that a rectangle is a quadrilateral in which all angles are right angles (90°)
Each pair of interior angles are supplementary. The two right angles add to a straight angle which means that the opposite sides of a rectangle are parallel.
In quadrilateral ABCD, if m∠A = m∠B = m∠C = m∠D = 90° then AB || DC and AD || BC
Hence, a rectangle is also a parallelogram.
Option B is the correct answer.
what is 84i?I'm learning about imaginary numbers but I need extra help
The imaginary number 'i" can be written in another form below:
[tex]i=\sqrt[]{-1}[/tex]Whenever we have the root of a negative number, we use the imaginary number 'i' to write it in an easier form.
For example:
[tex]\begin{gathered} \sqrt[]{-4}=\sqrt[]{-1\times4} \\ =\sqrt[]{-1}\times\sqrt[]{4} \\ =2\times\sqrt[]{-1} \\ =2\times i \\ =2i \end{gathered}[/tex]Therefore:

Answer: C(x) > a(x) , meaning c(X) has the greatest average rate of change over the given interval.
Explanations :
• The greatest average rate of change = slope
,• given by formula :
[tex]m\text{ = }\frac{y_2-y_1}{x_2-x_1}[/tex](a) For a(x),[tex]\begin{gathered} minitial\text{ = }\frac{-2+3\text{ }}{0+1\text{ }} \\ \text{ = 1/1} \\ \text{ = 1 } \end{gathered}[/tex][tex]\begin{gathered} m\text{ final = }\frac{13-6}{3-2} \\ \text{ = }7\text{ } \end{gathered}[/tex]• The average rate of change over the given interval = 7-1 = 6
(b) for b(x) , we have [tex]\begin{gathered} M\text{ initial = }\frac{3-1}{0+1} \\ \text{ = 2} \end{gathered}[/tex]and
[tex]\begin{gathered} m\text{ final = }\frac{9-7\text{ }}{3-2\text{ }} \\ \text{ = 2} \end{gathered}[/tex]• We can see that b(x) has constant average rate of change at 2 , therefore this will not be considered for this purpose of the exercise.
(c) for C(x) , we have [tex]\begin{gathered} M\text{ initial = }\frac{-1+2}{0+1} \\ \text{ = 1 } \end{gathered}[/tex]
and
[tex]\begin{gathered} m\text{ final = }\frac{13-5\text{ }}{3-2} \\ \text{ = }8\text{ } \end{gathered}[/tex]• The average rate of change over the given interval =, 8 -1 = 7
in conclusion , C(x) = 7 , whereas a(x) = 6 ,
Therfore C(x) > a(x)
Given sin 60degrees √ 3/2 find cos 60°
cos 60°
Step-by-step explanation:
if I understand you correctly, then you got
sin(60°) = sqrt(3/2)
and now we have to find cos(60°) based on that.
but : sin(60°) = sqrt(3/4) = sqrt(3)/2
I will continue with that.
one major observation with the trigonometric functions in a norm circle (radius = 1) is that sine and cosine are the legs of a right-angled triangle.
the radius at the angle is the Hypotenuse.
and so, Pythagoras applies
c² = a² + b²
c is the Hypotenuse, a and b are the legs.
so,
radius² = sin²(x) + cos²(x)
and because radius = 1
1² = 1 = sin²(x) + cos²(x)
in our case
1 = sin²(60) + cos²(60)
1 = (sqrt(3)/2)² + cos²(60) = 3/4 + cos²(60)
cos²(60) = 1 - 3/4 = 1/4
cos(60) = sqrt(1/4) = 1/2

On a particular production line the likelihood that a light bulb is defection is 5%. Ten light bulbs are randomly selected. What is the probability that at most 3 of the light bulbs will be defective
The probability that at most 3 of light bulbs will be defective will be 0.998.
Probability may be defined as an expression which may be used to determine the possibility of occurring of any event. The probability of happening an event surely is 1 and probability of not happening an event is zero. Since, 5 percent of bulbs are defective then
5% = 0.05 Now,
Non defective bulbs = 1 - 0.05 = 0.95
n = number of light bulbs = 7
We can calculate this using binomial distribution.
p(x) = ⁿCₓ × (pˣ)(1-p) ^n-x
Our question says at most 3 is defective, so it will be
(⁷C₀ × 0.05⁰ × 0.95⁷) + (⁷C₁ × 0.05¹ × 0.95⁶) + (⁷C₂ × 0.05² × 0.95⁵) + (⁷C₃ × 0.05³ × 0.95⁴)

2 |x - 4| - 8 = x
So, x - 4 = (x + 8)/2
= -(x + 8)/2
When,
x - 4 = (x + 8)/2
2x - 8 = x + 8 (Multiplying by 2)
2x - x = 8 + 8 (Adding 8 and subtracting x to both sides)
x = 16
When,
x - 4 = - (x + 8)/2
2x - 8 = -x - 8 (Multiplying by 2)
2x + x = -8 + 8 (Adding 8 and x to both sides)
3x = 0
x = 0
Hence, the solution is x = 16 and x = 0.
13. (3/4)x = 2x - 10
⇒ Subtract 2x from both sides.
-5x/4 = -10
Multiply both sides by 4/(-5).
