Answer:
264 transistors.
Step-by-step explanation:
By proportion the total number made if 16 are faulty is (35/2) * 16
= 280.
The number of good ones is 280 - 16
= 264 transistors.
Answer:
264 good ones
Step-by-step explanation:
2 in 35 are faulty = in a batch of 35, 2 will be faulty = there are 33 good for every 2 faulty ones there are
16 faulty have been made - to figure out how many batches there have been do 16/2=8
8 batches of 35, 8 × 35 = 280 total
280 total - 16 faulty = 264 good
OR do 8 batches × 33 good per batch = 264 good

Let's say that you are interested in opening an inverstment account that you will keep for at least 20 years. Compare the future values of that account using simple interest and compound interest if the interest rate is 2.6% and is compounded annually. Which type of interest (simple or compound) would you choose for your investment and why?
Answer:
over 20 years, the value of the compound interest account is about 10% moremy choice is the compound interest account because of its higher earningsStep-by-step explanation:
For principal amount P, the future value of the simple interest account will be ...
P(1 + rt) = P(1 + .026·20) = 1.52P
The future value of the compound interest account will be ...
P(1 +r)^t = P(1.026^20) ≈ 1.6708875P
The value of the compound interest account is about 10% greater after 20 years.
I would choose the compound interest account because it has a higher rate of return.
Which equation represents a circle with the same center as the circle shown but with a radius of 2 units?
Answer:
Option 2: (x-4)^2 + (x-5)^2 = 4
Step-by-step explanation:
The given circle's center is: (4,5)
And the radius is 4 units.
We are told in the question that the center will remain same only the radius will be changed.
The center is denoted by (h,k) = (4,5) and radius is 2
Standard equation of circle is:
(x-h)^2 + (y-k)^2 = r^2
So the equation of another circle with same center and radius of 2 units will be:
(x-4)^2 + (x-5)^2 = 2^2
(x-4)^2 + (x-5)^2 = 4
Hence option 2 is correct ..
Which Statements about Trapezoids and Rhombuses are true?

Option A & B are true about trapezoids and rhombuses.
What are trapezoids and Rhombuses?
A trapezoid is a polygon that has only one pair of parallel sides. These parallel sides are also called parallel bases of trapezoid. The other two sides of trapezoids are non-parallel and called legs of trapezoids.
A rhombus is a special case of a parallelogram. In a rhombus, opposite sides are parallel and the opposite angles are equal. Moreover, all the sides of a rhombus are equal in length, and the diagonals bisect each other at right angles. The rhombus is also called a diamond or rhombus diamond.
Now determine which statement is true about trapezoid and rhombuses
We have given,
Option A: Both shapes are 2-dimensional figures.
This option is true because both trapezoid and rhombuses are a type of quadrilateral and we know quadrilaterals are 2 dimensional figures.
Option B: The first shape has the same number of angles as the second shape.
Yes,this option is true because both the shapes are quadrilateral type and a quadrilateral is a closed polygon containing 4 sides and 4 vertices enclosing 4 angles.
Option C: Both shapes have all sides of equal length.
No,this is not true as rhombus has all sides of equal length but trapezoid has all sides of different length.

How many positive integers are there whose digits strictly increase from left to right?
There are 511 positive integers whose digits strictly increase from left to right.
To determine how many positive integers have digits that strictly increase from left to right, we need to consider combinations of digits. Since the digits must strictly increase, we cannot repeat any digit, and we can only use digits from 1 to 9.
Each number can be considered a unique combination of these digits, where the order of digits matters. For example, the digits {1, 2, 3} can only form the number 123. The total number of such combinations is given by the binomial coefficient C(9, k), where k is the number of digits.
For 1-digit numbers, the count is :C(9, 1) = 9For 2-digit numbers :C(9, 2) = 36For 3-digit numbers :C(9, 3) = 84And so on, up to 9-digit numbers which is :C(9, 9) = 1Summing these values, we get the total number of positive integers with strictly increasing digits :9 + 36 + 84 + 126 + 126 + 84 + 36 + 9 + 1 = 511Therefore, there are 511 positive integers whose digits strictly increase from left to right.You have recorded your car mileage and gasoline use for 5 weeks.

Tom and Shirley, working together can mow the lawn in 6 hours working alone Shirley takes three times as long as Tom how long does it take Tom to mow the lawn alone
Answer:
It would take Tom 8 hours alone
Step-by-step explanation:
We are looking at this basic equation:
Tom + Shirley = 8 hours
Tom takes x hours to cut the grass; this means that 1/x of the job gets done in 1 hour
It takes Shirley 3 times as long as Tom, so it takes her 3x hours to cut the grass; this means that 1/3x of the job gets done in 1 hour
If the total number of hours it takes them to do the job is 6 hours; this means that 1/6 of the job gets done in 1 hour
Looking back at the original basic equation, we will fill in our info:
[tex]\frac{1}{x}+\frac{1}{3x}=\frac{1}{6}[/tex]
We can solve for x by first finding the LCD and eliminating the denominators. The LCD is 6x, since all the denominators go into 6x evenly.
We will multiply the rational equation through by the LCD:
[tex]6x[\frac{1}{x}+\frac{1}{3x}=\frac{1}{6}][/tex]
Dividing each denominator into the LCD gives us:
6 + 2 = x so
x = 8
This means that it takes Tom 8 hours to do the job alone. It would take Shirley 24 hours alone. Ugh.
The time it would take Tom to mow the lawn alone is 3 hours
How to determine the value?From the information given;
Let Tom's working hours be x.
Let Shirley's working hours be y.
We have that;
Shirley and Tom work 6 hours together, this is expressed as;
x + y = 6
Given that Shirley work 3 hours alone, we have;
y = 3
Substitute the value of y as 3 in the equation
x + 3 = 6
x = 6 - 3
x = 3
Thus, the time it would take Tom to mow the lawn alone is 3 hours

Triangle ABC has coordinates A (0, 1) B (0, 2) and C (3,2). If Triangle ABC is equivalent to triangle EDF, what is the measure of DF?
3
3.2
4
4.4
Answer:
3
Step-by-step explanation:
Segment BC corresponds to segment DF. The length of BC is the distance between coordinates (0, 2) and (3, 2). These points are on the same horizontal line (y=2), so the distance between them is the difference of their x-coordinates: 3 - 0 = 3.
Answer:
DF = 3
Step-by-step explanation:
If ABC is equivalent to EDF, then DF is equivalent to BC, which form the following ordered pairs:
D = (0,2)
F = (3,2)
It can be seen that both pairs have the same value of "y" or second value, that is 2.
As a rule, when the points are located on the y-axis (of the ordinates) or on a line parallel to this axis, the distance between the points corresponds to the absolute value of the difference of their ordinates.
So,
DF = D(x) + F(x) = 0 + 3 = 3
If we apply the equation of the distance between two points we get the same result,
[tex]DF=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }=\sqrt{(3-0)^{2}+(2-2)^{2} }=\sqrt{(3)^{2}+(0)^{2} }=\sqrt{9+0 }=\sqrt{9}=3[/tex]

Write the standard form of the equation that is parallel to y = -6x + 5 and goes through point (4, 4).
6x + y = 28. The standard form of the equation that is parallel to y = -6x + 5 and goes through point (4, 4) is 6x + y = 28.
The equation is written in the slope-intercept form y = mx +b. So:
y = -6x + 5
The slope m = -6
Since the slopes of parallel lines are the same, we are looking for a slope line m = -6 and goes through point (4, 4).
With the slope-intercept form:
y = mx + b
Introducing the slope m = -6:
y = -6x + b
Introducing the point (4, 4):
4 = -6(4) + b
b = 4 + 6(4)
b= 24 + 4
b = 28
Then
y = -6x + 28
write the equation in standard form ax + by = c:
y = -6x + 28
6x + y = 28

Suppose that a single card is selected from a standard 52-card deck. What is the probability that the card drawn is a clubclub?
Now suppose that a single card is drawn from a standard 52-card deck, but it is told that the card is blackblack. What is the probability that the card drawn is a clubclub?
Answer:
The probability that the card drawn is a club is 0.25.
The probability that card drawn is a club, when it is given that the card is black is 0.5.
Step-by-step explanation:
In a standard deck of cards:
Total number of cards = 52
Total number of cards of each suit (club, spade,heart, diamond) = 13
The probability that the card drawn is a club is
[tex]P=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]P=\frac{^{13}C_1}{^{52}C_1}=\frac{13}{52}=0.25[/tex]
Therefore the probability that the card drawn is a club is 0.25.
Let A and B represents the following events:
A : Card is black
B : Card is a club
Total number of black cards = 26
[tex]P(A)=\frac{26}{52}=\frac{1}{2}=0.5[/tex]
From the above parts
[tex]P(B)=0.25[/tex]
Total number of black club cards = 13
[tex]P(A\cap B)=\frac{13}{52}=\frac{1}{4}=0.25[/tex]
We need to find the probability that card drawn is a club, when it is given that the card is black.
[tex]P(\frac{B}{A})=\frac{P(A\cap B)}{P(A)}[/tex]
[tex]P(\frac{B}{A})=\frac{0.25}{0.5}=0.5[/tex]
Therefore the probability that card drawn is a club, when it is given that the card is black is 0.5.

|a||b|cos(α + β)
|a||b|cos(α - β)
Answer:
axbx + ayby |a||b|(cosαcosβ + sinαsinβ) |a||b|cos(α - β)Step-by-step explanation:
The dot product is the sum of products of the corresponding coordinate values:
[tex]\text{\bf{a}$\cdot$\bf{b}}=a_{x}b_{x}+a_{y}b_{y}[/tex]
The value of this can also be written in terms of the magnitudes of the vectors and the angle θ between them:
|a|·|b|·cos(θ)
But the angle between the vectors is the same as the difference of their individual angles, θ = α - β, so this can also be written as ...
|a|·|b|·cos(α-β)
And the trig identity for the cosine of the difference of angles lets us write the above as ...
= |a|·|b|·(cos(α)cos(β) +sin(α)sin(β))

Find the area of a sector with a central angle of 170° and a radius of 17 millimeters. Round to the nearest tenth. Question 9 options: 857.5 mm2 100.9 mm2 428.7 mm2 25.2 mm2
Answer:
428.7 mm²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × [tex]\frac{170}{360}[/tex]
= π × 17² × [tex]\frac{17}{36}[/tex]
= 289π × [tex]\frac{17}{36}[/tex]
= [tex]\frac{289(17)\pi }{36}[/tex] ≈ 428.7 mm²
The area of a sector with a central angle of 170° and a radius of 17 mm is calculated using the sector area formula, resulting in approximately 428.7 mm², rounded to the nearest tenth.
To find the area of the sector, we use the formula [tex]\( \text{Area} = \frac{\text{Central Angle}}{360\°} \times \pi \times \text{Radius}^2 \)[/tex]. Substituting the given values, we get [tex]\( \text{Area} = \frac{170\°}{360\°} \times \pi \times 17^2 \)[/tex]. Simplifying, we have [tex]\( \text{Area} = \frac{17^2}{2} \times \pi \)[/tex]. Evaluating this expression, we find [tex]\( \text{Area} \approx 428.7 \)[/tex] mm². Therefore, the area of the sector, rounded to the nearest tenth, is approximately 428.7 mm². This calculation represents the portion of the circle enclosed by the given central angle and radius, providing the area of the sector.
Complete the square for 3x2 - 12x = 9.
Answer:
[tex] x=2 \pm \sqrt{7} [/tex]
Step-by-step explanation:
Given this form ax^2+bx=k, here are my steps for completing the square while answer your question:
First step: Divide both sides by what is in front of x^2. You want the coefficient of x^2 to be 1. To do this for your question, divided both sides by 3.
This gives us x^2-4x = 3.
Second step: We are ready to begin the completing the square process at this step. We are going to add (b/2)^2 on both sides. For this question b=-4.
So we will be adding (-4/2)^2 on both sides.
This gives us x^2-4x+(-4/2)^2=3+(-4/2)^2.
Third step: I like to simplified the things inside the square and I do not actually apply the square at this step. It makes a later step easier in my opinion.
So this step gives us x^2-4x+(-2)^2=3+(-2)^2.
Fourth step: I'm actually going to write the left hand side as a square. Just drag the things that are inside the squares down into ( )^2.
This is what I mean x^2-4x+(-2)^2=(x-2)^2.
So at the end of this step we have (x-2)^2=3+(-2)^2.
Fifth step: I'm going to simplify the right hand side.
This step gives us (x-2)^2=7
Sixth step: We are ready to square root both sides.
This gives us [tex] x-2=\pm \sqrt{7} [/tex]
Seveth step: Get x by itself like you normally would with a linear equation. My step here is just to add 2 on both sides.
Final answer: [tex] x=2 \pm \sqrt{7} [/tex]
[tex]3x^2-12x=9\\x^2-4x=3\\x^2-4x+4=7\\(x-2)^2=7\\x-2=\sqrt7 \vee x-2=-\sqrt7\\x=2+\sqrt7\vee x=2-\sqrt7[/tex]

A wholesaler requires a minimum of 4 items in each order from its retail customers. The manager of one retail store is considering ordering a certain number of sofas, x, and a certain number of pillows that come in pairs, y. Which graph represents the possible combinations of sofa and pillow orders the manager can have?
Answer:
It is the last graph: solid line, shaded area over the line x = 2 - x/2Explanation:
1) Set the algebraigic expression that represents the combinations of sofa and pillow orders:
Number of sofas: x (given)Number of pillows: 2y (given, since they come in pairs)Number of items = number of sofas + number of pillows = x + 2yMinimum of 4 items in each order (given) ⇒ x + 2y ≥ 42) Predict the graph of the inequality x + 2y ≥ 4
The border line is the equation x + 2y = 4You can choose two points to draw a lineChoose the axis-intercepst:x = 0 ⇒ 2y = 4 ⇒ y =4/2 ⇒ y = 2 ⇒ point (0,2)
y = 0 ⇒ x = 4 ⇒ point (4,0)
Then the lines goes through (0,2) and (4,0) ... [the four graphs meet this]
The shading area is above the line because when you solve for y you get y ≥ 2 - x/2, and the line is included because the "equal to" part of the symbol (≥ means greater than or equal to). To state that the line is included the graph uses a continous line instead of a dotted one.3) Conclusion:
That means that the correct graph is the last one: solid line, shaded area over the line y = 2 - x/2.
Note: a more detailed graph would include the fact that the items cannot be negative, i.e. x ≥ 0 and y ≥ 0, which would result in that the shaded area would be on the first quadrant.

b² = 2² +3² -2·2·3·cos(95°) ≈ 14.0459
b ≈ 3.74778
Then the law of sines can help you find angle A, the angle opposite the shortest side.
sin(A)/a = sin(B)/b
A = arcsin(a/b·sin(B)) = arcsin(2/3.74778·sin(95°)) ≈ 32.11°
A ≈ 32°
The smallest angle is about 32°.
$1000 is invested at 8%/a compounded daily for 10 years. What is the total interest earned?
Please help

btw, we could have used the compound formula just the same, by simply using a compounding cycle of 365, namely daily, assuming a year has 365 days.
If f(x) is the height, in cm, of a sunflower plant that is x days old, which of the following statements best describes the meaning of f(60) = 210?
A.) The height of the sunflower plant is 60 cm when it is 210 days old.
B.) The height of the sunflower plant is 210 cm when it is 60 days old.
C.) The height of the sunflower plant is 210 cm when it is 3.5 days old.
D.) The height of the sunflower plant is 60 cm when it is 3.5 days old.
Answer:
B
Step-by-step explanation:
We are given f(x) is height in cm while x is days old.
We are also given f(60)=210.
If you compare f(60) to f(x) you should see that x is 60 so we have the sunflower is 60 days old. Since f(60)=210, then you have the height of the sunflower is 210 cm tall.
Answer:
B.) The height of the sunflower plant is 210 cm when it is 60 days old.
Step-by-step explanation:
The vertex of this parabola Is at (-3,6) which of the following could be its equation
Step-by-step explanation:
the e standard form of parabola with vertex (h,k) is
y=a(x-h)²+k
here (h,k)=(-3,6)
so the answer to your question is
y=-3(x-(-3))²+6
y=-3(x+3)²+6
Answer:
Option D is correct.
Step-by-step explanation:
The vertex is (-3,6)
We will check which equation satisfies the given vertex.
A) y = -3(x-3)^2 - 6
if x = -3 then value of y should be 6
Checking:
y = -3(-3-3)^2 - 6
y = -3(-6)^2 - 6
y = -3(36) -6
y = -114
if x= -3, y ≠ 6
B) y = -3(x+3)^2 - 6
if x = -3 then value of y should be 6
Checking:
y = -3(-3+3)^2 - 6
y = -3(0)-6
y = -6
if x= -3, y ≠ 6
C) y = -3(x-3)^2 + 6
if x = -3 then value of y should be 6
Checking:
y = -3(-3-3)^2 + 6
y = -3(-6)^2 + 6
y = -3(36) + 6
y = -102
if x= -3, y ≠ 6
D) y = -3(x+3)^2 + 6
if x = -3 then value of y should be 6
Checking:
y = -3(-3+3)^2 + 6
y = -3(0)^2 + 6
y = 6
So, if x= -3, y =6 so, if the vertex of parabola is at (-3,6) the equation will be
y = -3(x+3)^2 + 6
So. Option D is correct.
