Digitalis is a technology company that makes high-end computer processors. Their newest processor, the luteA, is going to be sold directly to the public. The processor is to be sold for $4500 , making Digitalis a profit of $383 . Unfortunately there was a manufacturing flaw, and some of these luteA processors are defective and cannot be repaired. On these defective processors, Digitalis is going to give the customer a full refund. Suppose that for each luteA there is an 11% chance that it is defective and an 89% chance that it is not defective. If Digitalis knows it will sell many of these processors, should it expect to make or lose money from selling them? How much?




To answer, take into account the profit earned on each processor and the expected value of the amount refunded due to the processor being defective.

Answer:

x = 45

Step-by-step explanation:

The sum of the angles of a triangle is 180

80+55+x = 180

135 +x = 180

Subtract 135 from each side

x = 180-135

x =45

Answer:

45

Step-by-step explanation:

combining the a and b lengths gives you 135 then subtract by 180 and you get 45.

Answer:

F, y-axis

Step-by-step explanation:

If point E's y-coordinate is 0, it is located somewhere on the y-axis (meaning F is correct). If point E's x-coordinate is 0, it cannot be on the x-axis (meaning E is incorrect). When a point is on the y-axis, it does not fall into any quadrant (meaning A, B, C, and D are incorrect).

Answer:

B) -7x + 7y = -49

Step-by-step explanation:

This is a y=x plot/line shifted by 7 units.

This can also be verified plugging in the values of x=0,y=-7 and x=7,y=0. The only equation which satisfies these points in Equation B. These points have been chosen as they're the intercepts of this plot.

Answer:

-7x+7y=-49

Step by step Explanation:

This can be verified by giving x=0 and y= -7; x=7 and y=0. The second equation only assures this. Therefore the second equation is correct.

Answer:

A

Step-by-step explanation:

360 - 150 = 210

210 / 3 = 70

but hat doesn't really help..

so lets do this,

add each one of the groups up, if one adds up to 210, its the right one.

A = 210

B = 190

C = 255

D = 255

First, find the total distance between A and B.

3 + 21 = 24 units

Second, divide by 8.

24 / 8 = 3

Third, multiply by 3.

3 * 3 = 9

Therefore, the answer is 3.

Best of Luck!

Answer:

D 6

Step-by-step explanation:

First, we find the distance between points A and B.

AB = |a - b| = |-3 - 21| = |-24| = 24

The distance from A to B is 24.

Now we need 3/8 of that distance.

3/8 of 24 = 3/8 * 24 = 3/8 * 24/1 = 72/8 = 9

Point Q is 9 units to the right of point A.

-3 + 9 = 6

Answer: D 6

Answer:

Look at the figure and take note of the types of three-dimensional figures that make it up. Find the volume of each figure. Add the volumes to find the total volume.

Step-by-step explanation:

The volume of the composite figure is solved

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.

The volume of a prism is the product of its base area and height

Volume of Prism = B x h

where B = base area of prism

h = height of prism

Given data ,

If a composite figure is made up of a rectangular prism and a triangular prism, you can find the volume of the rectangular prism by multiplying its length, width, and height. Then, you can find the volume of the triangular prism by multiplying its base, height, and 1/2. Finally, you can add the volumes of both prisms to get the total volume of the composite figure.

Similarly, if a composite figure is made up of two rectangular prisms, you can find the volume of each prism by multiplying its length, width, and height. Then, you can add the volumes of both prisms to get the total volume of the composite figure.

Answer:

I believe 1 3/4

Step-by-step explanation:

Find the area of the circle:

Area = PI x r^2

Area = 3.14 x 9^2

Area = 3.14 x 81

Area = 254.34 square cm

Now multiply the area of the circle by the shaded portion which is the fraction of the degree over 360 degrees:

254.34 x 80/360 = 20,347.2/360 = 56.52

The shaded area is 56.52 square cm.

Area of circle formula: A = πr²

A = π(9)²

A = 81π

A = 254.34cm²

The ratio of degrees in the shaded region to total degrees in a circle:

80/360 = 40/180 = 20/90 = 10/45 = 2/9

Multiply:

254.34/1 * 2/9

508.68/9

56.52

Therefore, the area of the shaded region is 56.52cm²

Answer:

y = 90°

Step-by-step explanation:

y + x = 110° because the sum of two interior angles is equal to an interior angle

x + 70° = y ➡ y - x = 70°

y + x = 110°

y - x = 70° add two equations

2y = 180° (x eliminated -x)

y = 90°

Answer:

(0,-21)

Step-by-step explanation:

The x value of a y intercept is always 0

So we can plug in 0 to the equation to solve for the y intercept

(2*0-3)(3*0+7)

-3*7= -21

y intercept: (0,-21)

Answer:

-21

Step-by-step explanation:

f(x)=(2x-3)(3x+7)

The y intercept is when x=0

f(0) = (0-3) (0+7)

     -3*7

    -21

The y intercept is -21

Answer:

Courthouse' Area= 5027

Larry is correct.

Step-by-step explanation:

Answer:

Zero is even (not odd, not neutral)

Zero is neither positive nor negative (the only number with this property)

Zero is an integer (and must be considered when question limits choices to integers)

Zero is a multiple of all numbers (x*0 = 0, so a multiple of any x)

Step-by-step explanation:

Any number to the power of 0 is equal to 1. 0 is neither positive nor negative. 0 is neither prime nor composite. If you add two numbers and the sum is zero, we call the two numbers additive inverses or opposites of each other.

Opens upward since a is positive(meaning it has a minimum vertex)

Y-int: (0,0)

Step-by-step explanation:

y=[tex]x^{2}[/tex]+7x

In order to find, the y-intercept, x has to be 0, so plug in 0 for x

y=[tex]0^{2}[/tex]+7(0)

y=0

So the y intercept: (0,0)

The equation form a parabola that opens up and the y intercept is at y = 0. a = 1, b = 7 and c = 0

A quadratic function is in the form:

y = ax² + bx + c

Given that:

y = x² + 7x, hence:

a = 1, b = 7 and c = 0

The equation form a parabola that opens up and the y intercept is at y = 0.

Answer:

Because you are looking for square inches of wrapping paper, you are looking for the surface area of the box. A three-dimensional box has a top and bottom that are the same size, a front and back that are the same size, and 2 sides that are the same size...or SA = 2(top/bottom area) + 2(front/back area) + 2(side/side area). Our equation fills in nicely like this:

SA = 2(6 * 14) + 2(6 * 8) + 2(14 * 8)

SA = 2(84) + 2(48) + 2(112)

SA = 168 + 96 + 224

SA = 488 square inches of paper to wrap the box.
