When Digitalis knows that it'll sell many of the processors, it's expected to make money since there's a higher probability that it's not defective.
How to illustrate the probability?Since the processor is sold for $3300 and a profit of $429 is made, the selling price will be:
= $3300 - $429
= $2871
In this case, there's a 13% chance that it's defective and 87% that's it's not defective. Therefore, it's expected to make money since there's a higher probability that it's not defective.

Answer:
d. 0.771.
Step-by-step explanation:
This probability is equal to the area other than the green triangle divided by the total area of backyard.
Total area = 120^2 = 14400
Area of green triangle = 1/2 * 120 * 55 = 3300
So area of the part of yard not covered by the triangle = 14400 - 3300
and the required probability = (14400 - 3300) / 14400
= 0.771.
Answer:
d. 0.771
Step-by-step explanation:
What is probability?
Probability is the likelihood of the occurrence of something.
In simpler terms we can say probability = # of favorable outcomes / total # of outcomes.
Understanding the question
Here we have a square and a triangle inside of the square and we want to find the probability that a tennis ball thrown inside of the square will not land inside of the triangle.
So we have # of favorable outcomes as the area of the outside of the triangle but inside of the square ( so area of square - area of triangle ) and we have total # of outcomes as the total area of the square including the triangle
Finding the areas
Area of square
Area of square = (side length)²
the square shown has a given side length of 120ft
So area = 120² = 120 × 120 = 14400
Area of triangle
Area of a triangle = (base length × height) / 2
Here the base length is shared with the side length of the square menaing the base length of the triangle = 120 and the given height of the triangle is 55 feet
So area would = ( 120 × 55 ) / 2 = 3300
Finding the probability
Again we want to find the probability that a ball thrown in the square will not land in the triangle
This can be calculated using the probability formula we created earlier
probability = ( area of square - area of triangle ) / area of square
we have area of square = 14400 and area of triangle = 3300
so probability = (14400 - 3300) / 14400
==> subtract 3300 from 14400
probability = 11100 / 14400 = 0.771 ( rounded )
And we are done!

Suppose there is a simple index of two stocks, stock A and stock B. Stock A opens on Monday with 10,000 shares at $5.50 per share. Stock B opens on Monday with 8000 shares at $6.25 per share. Stock A opens on Tuesday at $5.80 per share, and stock B opens on Tuesday at $6.65 per share. Both stocks have the same number of shares that they opened with on Monday. What is the rate of change of this simple index over 1 day?
A. 5.6%
B. 5.9%
C. -5.6%
D. -5.9%
Answer:
sorry but I do know that it is A or B hope this helps.
The rate of change of the given simple index over 1 day is -0.9%.
What is rate of change?When something has a constant rate of change, one quantity changes in relation to the other.
Given that;
Stock A opens on Monday with 10000 shares at $5.50 per share.
Stock B opens on Monday with 8000 shares at $6.25 per share.
Stock A opens on Tuesday at $5.80 per share, and stock B opens on Tuesday at $6.65 per share.
Total value of the simple index at Monday is;
= (10000×5.50) + (8000×6.25)
= 55,000 + 50,000
= 105,000
The total value of the simple index at Tuesday is;
= (10000×5.80) + (8000×6.65)
= 58,000 + 53,200
= 111,200
The rate of change of this simple index over 1 day is;
= (111,200-105,000)/(10000-8000) -1
= 6,200/2000 - 1
= 3.1 - 1
= 2.1
Hence, the rate of change of the given simple index over 1 day is -0.9%.

b. 55.722
Step-by-step explanation:
1850/3320
I assume that you know what the question is asking to solve for.
The net profit margin for Korey's Comics is 42.5%.
Option A is the correct answer.
What is a profit?Profit is the difference between the selling price and the cost price.
We have,
Net profit margin is calculated by dividing net income by net sales and multiplying the result by 100 to get a percentage.
Net Profit Margin = (Net Income / Net Sales) x 100%
Substituting the given values.
Net Profit Margin = (1,850 / 4,350) x 100%
Net Profit Margin = 0.425 x 100%
Net Profit Margin = 42.5%
Therefore,
The net profit margin for Korey's Comics is 42.5%.

A) The function f is defined by : f(x) = x2+ax+b
a and b are constants.
It is known that: f(0) = 7 and f(-2) = 17
Find the values of a and b.
B) Use the values of a and b to solve this equation: f(x) = 35
x = __ or x = __?
Answer:
A. a = -3 and b = 7.
B. x = -4 or x = 7.
Step-by-step explanation:
A)
f(0) = 0^2 + a(0) + b = 7
So b = 7.
f(-2) = (-2)^2- 2a + 7 = 17
4 - 2a = 17 - 7
4 - 2a = 10
-2a = 10 - 4 = 6
-2a = 6/-2
a = -3.
B)
Substituting a = -3 and b = 7 we get:-
x^2 - 3x + 7 = 35
x^2 - 3x - 28 = 0
(x - 7)(x + 4) = 0
x - 7 = 0 or x + 4 = 0
x = -4 or x = 7.

What is the surface area of the triangular prism shown?
Answer:
The first step that we are going to do is to solve the area of the top rectangle. We are given a width of 15 cm and a length of 25 cm so we can just multiply them against each other to get the area.
[tex]Area = l * w[/tex]
[tex]Area = 25\ cm * 15\ cm[/tex]
[tex]Area = 375\ cm^2[/tex]
The second side that we are going to solve for is the bottom rectangle. We are given a width of 12 cm and a length of 25 cm so lets just multiply them against each other to get the area.
[tex]Area = l * w[/tex]
[tex]Area = 25\ cm * 12\ cm[/tex]
[tex]Area = 300\ cm^2[/tex]
The next area that we are going to determine is the back rectangle which has a width of 9 cm and a length of 25 cm so lets just multiply them against each other to get the area.
[tex]Area = l * w[/tex]
[tex]Area = 25\ cm * 9\ cm[/tex]
[tex]Area = 225\ cm^2[/tex]
The final area that we have to determine are the side triangles. After determining the area of one triangle we will have to multiply it by 2 to get the area for both of the triangles. We are given a base of 12 cm and a height of 9 cm so lets just use the formula to find the area.
[tex]Area = \frac{1}{2}* b*h[/tex]
[tex]Area = \frac{1}{2}* 12\ cm*9\ cm[/tex]
[tex]Area = 54\ cm^2[/tex]
Multiply it by two to get the area for both of the triangles.
[tex]Area = 54\ cm^2 * 2[/tex]
[tex]Area = 108\ cm^2[/tex]
Finally, we are onto the last part which is to add up all of the areas and get the surface area after we combine everything.
[tex]Area_{total}=375\ cm^2 + 300\ cm^2 + 225\ cm^2 + 108\ cm^2[/tex]
[tex]Area_{total}=1008\ cm^2[/tex]
Therefore, our final answer is option B, 1008 [tex]cm^2[/tex]

What is combination?This is the number of ways in which x objects can be selected out of n objects. It is given mathematically as ⁿCₓ = n!/x!(n - x)!
The number of different combo mealsNow, given that the customer can choose among 5 drinks, 4 main dishes, and 5 sides.
There are ⁵C₁ ways of choosing the drinks.
So, ⁵C₁ = 5!/1!(5 - 1)!
= 5!/1!/4!
= 5
There are ⁴C₁ ways of choosing the main dishes.
So, ⁴C₁ = 4!/1!(4 - 1)!
= 4!/1!/3!
= 4
There are ⁵C₁ ways of choosing the sides.
So, ⁵C₁ = 5!/1!(5 - 1)!
= 5!/1!/4!
= 5
So, total number of ways of choosing the combo meals is
⁵C₁ × ⁴C₁ × ⁵C₁ = 5 × 4 × 5
