Samples of emissions from three suppliers are classified for conformance to air-quality specifications. The results from 100 samples are summarized as follows:
Conforms
Yes No
1 22 8
Supplier 2 25 5
3 30 10
Let A denote the event that a sample is from supplier 1, and let B denote the event that a sample from any supplier conforms to specifications. If a disk is selected at random, determine the following probabilities. Input your answers in the fractional form (do not simplify).
a. P(A)=0.3
b. P(B)=0.77
c. P(A Intersection B) =0.22
d. P(A U B)=0.85
Answer:
[tex]P(A) = \frac{30}{100}[/tex]
[tex]P(B) = \frac{77}{100}[/tex]
[tex]P(A\ n\ B) = \frac{22}{100}[/tex]
[tex]P(A\ u\ B) = \frac{85}{100}[/tex]
Step-by-step explanation:
Given
See attachment for proper format of table
[tex]n = 100[/tex] --- Sample
A = Supplier 1
B = Conforms to specification
Solving (a): P(A)
Here, we only consider data in sample 1 row.
In this row:
[tex]Yes = 22[/tex] and [tex]No = 8[/tex]
So, we have:
[tex]n(A) = Yes + No[/tex]
[tex]n(A) = 22 + 8[/tex]
[tex]n(A) = 30[/tex]
P(A) is then calculated as:
[tex]P(A) = \frac{n(A)}{Sample}[/tex]
[tex]P(A) = \frac{30}{100}[/tex]
Solving (b): P(B)
Here, we only consider data in the Yes column.
In this column:
[tex](1) = 22[/tex] [tex](2) = 25[/tex] and [tex](3) = 30[/tex]
So, we have:
[tex]n(B) = (1) + (2) + (3)[/tex]
[tex]n(B) = 22 + 25 + 30[/tex]
[tex]n(B) = 77[/tex]
P(B) is then calculated as:
[tex]P(B) = \frac{n(B)}{Sample}[/tex]
[tex]P(B) = \frac{77}{100}[/tex]
Solving (c): P(A n B)
Here, we only consider the similar cell in the yes column and sample 1 row.
This cell is: [Supplier 1][Yes]
And it is represented with; n(A n B)
So, we have:
[tex]n(A\ n\ B) = 22[/tex]
The probability is then calculated as:
[tex]P(A\ n\ B) = \frac{n(A\ n\ B)}{Sample}[/tex]
[tex]P(A\ n\ B) = \frac{22}{100}[/tex]
Solving (d): P(A u B)
This is calculated as:
[tex]P(A\ u\ B) = P(A) + P(B) - P(A\ n\ B)[/tex]
This gives:
[tex]P(A\ u\ B) = \frac{30}{100} + \frac{77}{100} - \frac{22}{100}[/tex]
Take LCM
[tex]P(A\ u\ B) = \frac{30+77-22}{100}[/tex]
[tex]P(A\ u\ B) = \frac{85}{100}[/tex]

-2x + 6
X+ 12
y + 23

y =
Answer:
x = -2
y = -5
Step-by-step explanation:
Properties of a Parallelogram
Two pairs of opposite sides are parallel. Two pairs of opposite sides are equal in length. Two pairs of opposite angles are equal in measureThe diagonals bisect each other. Adjacent angles are supplementary. Each diagonal divides the quadrilateral into two congruent triangles.Each diagonal is divided into two measures expressed with variables. Since diagonals bisect each other:
y + 23 = -4y - 2. And
-2x + 6 = x + 12
Solve the first equation. Adding 4y:
5y + 23 = - 2
Subtracting 23:
5y = -25
Dividing by 5:
y = -5
Solve the second equation. Subtracting x and 6:
-3x = 6
Dividing by -3:
x = -2
Solution:
x = -2
y = -5

Answer:
x = 45
135°
Step-by-step explanation:
180 - 45 = 135
3x = 135
3x/3 = 135/3
x = 45
Answer:
45 degrees
Step-by-step explanation:
Since 45 and 3x are on a straight line together, they add up to 180 degrees. This means you can have the equation
45 + 3x = 180
subtract 45 from both sides
3x = 135
x = 45 degrees

Answer:
x = -1 and x = 11
Step-by-step explanation:

x + 1 = 0
x = -1
x - 11 = 0
x = 11
Amarosa Logistics purchased a new pick-up for the office employees to use for $28,000.00. The vehicle is expected to last for
10 years with a residual value of 56,250,00. For tax purposes, it is assumed that the depreciation is linear and the pickup's
value can be determined by the equation
p(t) = -21755 + 28,000,
where x is the number of years since the pick-up was purchased. What is the depreciated value of the pick-up after 3 years?
A $25,825.00
B. $21,475,00
C. $15,225.00
D 519,300.00
Answer:
I think B but I am not sure.
The depreciated value of the pick-up after 3 years is $15,225
Given that Amarosa Logistics purchased a new pick-up for the office employees to use for $28,000.00.
The vehicle is expected to last for 10 years with a residual value of 56,250,00.
The depreciation is linear and the pickup's value can be determined by the equation
p(t) = -21755t + 28,000
To find the depreciated value of the pick-up after 3 years
Plug in t as 3
p(t) = -21755(3)+ 28,000
=$15,225
Hence, $15,225 is the depreciated value of the pick-up after 3 years

find the perimeter of a isosceles right triangle having area of 200 CM square
Answer:
The perimeter of the isosceles right triangle is 68.28 cm.
Step-by-step explanation:
Given;
area of the isosceles right triangle, A = 200 cm²
let the two equal sides of the triangle = base (b) and height (h)
Area of the isosceles right triangle is calculated as;
[tex]A= \frac{1}{2} bh \\\\But, b = h\\\\A = \frac{1}{2} b^2\\\\200 = \frac{1}{2} b^2\\\\400 = b^2\\\\\sqrt{400} = b\\\\20 \ cm = b[/tex]
let the hypotenuse side of the isosceles right triangle = c
c² = b² + h²
c² = 20² + 20²
c² = 800
c = √800
c = 28.28 cm
The perimeter of the isosceles right triangle is calculated as;
P = b + h + c
P = 20 cm + 20 cm + 28.28 cm
P = 68.28 cm
Therefore, the perimeter of the isosceles right triangle is 68.28 cm.

The distance, y, in miles, traveled by a car for a certain amount of time, x, in hours, is shown in the graph below: A graph titled Motion of a Car is shown with Time in hours labeled on x-axis and Distance from Starting Point in miles labeled on y-axis. The scale on the x-axis shows the numbers 1, 2, 3, 4, 5, 6, and the scale on the y-axis shows the numbers 0, 13, 26, 39, 52, 65, 78. There are three straight lines in the graph. The first line joins ordered pair 0, 0 with 2, 26. The second straight line joins 2, 26 and 3,26 and the third straight line joins ordered pair 3,26 with the ordered pair 5,52. Which of the following best describes the motion of the car shown? (1 point) It travels for 2 hours, then stops for 3 hours, and finally travels again for 2 hours. It travels for 2 hours, then stops for 3 hours, and finally travels again for 5 hours. It travels for 2 hours, then stops for 1 hour, and finally travels again for 5 hours. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.
Answer:
The correct answer is the last choice. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.
Step-by-step explanation:
In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.
In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words, it didn't move.
In the last segment, it moved up again for 2 hours.
It travels for 2 hours, then stops for 1 hour, and finally travels again for 5 hours. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.
What is a simple definition of distance?Distance is the total movement of an object without any regard for direction. We can define distance as how much ground an object has covered despite its starting or ending point.
What is the scientific term for distance?Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

I WILL MARK BRAINLIEST PLEASE FIND ANGLE DAB ITS DUE AT 12 PLEASE HELP I WILL MARK BRAINLIEST
Answer: 65°
Explanation:
We are given that angle ACB is 40° and angle CAB is 25°.
Since the two triangles are congruent to each other, the angle of CAB is equal to the angle ACD- of which both are 25°
Similarily, angle ACB is equal to angle CAD- 40°
Knowing that angle CAB is 25° and angle CAD is 40°, simply add the two together to compute angle DAB:
25°+40°=65°
Thus, angle DAB is 65°

Carmen's water bottle holds 1 8/10 liters of water. Jorge's water bottle holds 2 2/5 liters of water. Jorge says his bottle holds about 1/2 liter more of water than Carmen's. Estimate if this is true or not. What is the actual difference?
Step-by-step explanation:
Carmen's water bottle = 1.8 litres ≈ 2 litres
Jorge's water bottle = 2[tex]\frac{2}{5}[/tex] = 2.4 litres ≈ 2 litres
Therefore, from estimate, Jorge's water bottle does not hold half litre more of water than Carmen's.
Actual difference = 2.4 - 1.8 = 0.6 litres
