A shipment of inexpensive digital watches, including that are defective, is sent to a department store. The receiving department selects 10 at random for testing and rejects the whole shipment if 1 or more in the sample are found defective. What is the probability that the shipment will be rejected?.
0.8926 percent of the time, the shipment will be rejected.
What is Probability?The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
According to the given information:A delivery of 50 cheap digital watches, 10 of which are flawed.
A digital watch's likelihood of malfunctioning
P = 10/50
= 0.2
Size of sample: n = 10
Additionally, if they find one or more samples to be defective, they reject the entire cargo.
Making use of the binomial probability formula:
[tex]P(x)={ }^{n} C_{x} p^{x}(1-p)^{n-x}[/tex]
The random variable x should stand in for the quantity of defective watches.
The chance that the delivery will be refused is:
[tex]P(x \geq 1)=1-P(0)[/tex]
= [tex]1-{ }^{10} C_{0}(0.2)^{0}(0.8)^{10}[/tex]
= 1 - (0.8)[tex]^{10}[/tex]
= 0.8926
As a result, 0.8926 percent of the time, the shipment will be rejected.

Using the online tool, find two different combinations of radius and height that produce two cylinders with nearly the same volume. Record the
dimensions and volumes of the two cylinders below.
The radii and the heights of the two cylinders are
Cylinder 1: Height = 6 and Radius = 5Cylinder 2: Height = 10 and Radius = 3.87How to determine the combinations of radius and height?The volume of a cylinder is
V = πr²h
When the volumes of two cylinders are almost equal, then it means that:
V1 ≈ V2
This gives
πr²h ≈ πR²H
Divide both sides by π
r²h ≈ R²H
Assume that r = 5 and h = 6
So, we have:
5² * 6 ≈ R²H
Evaluate the product
150 ≈ R²H
Assume H = 10
So, we have:
150 ≈ R² * 10
Divide by 10
R² ≈ 15
Take the square root of both sides
R ≈ 3.87
Hence, the radii and the heights of the two cylinders are
Cylinder 1
Height = 6 and Radius = 5
Cylinder 2
Height = 10 and Radius = 3.87

Formula for the Slope: (y2 - y1) / (x2 - x1)
You can use any two points to find the slope, as long as those two points are on the line.
Point 1 = (-2, 8)
Point 2 = (0, 0)
Slope = (0 - 8) / (0 - - 2)
Slope = -8 / 2
Slope = -4
Hope this helps!
Answer:
-4
Step-by-step explanation:
The formula to find the slope is (change in y)/(change in x). In other words, rise over run.
If we look at the data, we can see that the x and y value changes.
x value: -3 --> -2 --> -1 --> 0 --> 1
y value: 12 --> 8 --> 4 --> 0 --> -4
When y changed from 12 to 8, the x changed from -3 to -2.
y: 12 --> 8
x: -3 --> -2
There was a difference of -4 in the y and a difference of 1 in the x.
At the top, I wrote that the slope was (change in y)/(change in x)
With -4 and 1 we found, we can say that the slope is -4/1.
If we simplify this answer, we end up with -4.
So -4 is the slope of the data.
Which congruence postulate or theorem is stated below?

What are Congruent Triangles?Triangles that are referred to as congruent triangles are triangles that have corresponding congruent sides and corresponding congruent angles.
What is the Angle-angle-side Congruence Theorem (AAS)?According to the angle-angle-side congruence theorem (AAS) two triangles are congruent if two angles and a non-included side of one triangle are congruent to two corresponding angles and a non-included side of the other are congruent to each other.
For example, in triangles GUM and RED given in the image attached below, we have the following:
∠G ≅ ∠R [a pair of congruent angles]
∠M ≅ ∠D [a pair of congruent angles]
GU ≅ RD [a pair of non-included congruent side]

of
(A) 12
(B) 16
(C) 20
(D) 25
(E) 36
Answer:
C 20
Step-by-step explanation:
we need the distance between both points, then, as this is the side of a square, we square it and get the area of the square.
the distance we get via Pythagoras (the distance is the Hypotenuse of a right-angled triangle with the coordinate differences in x and y being the legs) :
distance² = (-1 -3)² + (1 - -1)² = (-4)² + 2² = 16+4 = 20
distance = sqrt(20)
the area of the square is the side², so again distance², and therefore the area is 20.

They are both 6.9 miles apart after one hour if they both hike 4 miles/hour
The correct option is (B)
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
According to the given information:Miranda and Cyndi start hiking from the same point. Miranda hikes at a heading of 270° or due west, and Cyndi hikes at a heading of 30°
From the isosceles triangle:h = 4sin30

Zhang is constructing a loading ramp (BA) that is 4-feet high (AC). The back of the base (BC) must be 12.8 ft. How long must the entire base (BD) be?
Proportion : __________________
Front of base: __________
Total base: __________
The front of the base is 1.25 ft and the total base is 14.05 ft.
How to find the side of a right triangle?A right triangle has one of its angles as 90 degrees. The side of a right angle triangle can be found using trigonometric ratios.
The sides CD and BD can be found using similar triangle principle.
In similar triangles, corresponding sides are always in the same ratio.
Therefore, the following proportion can be established as follows;
[tex]\frac{BC}{AC}=\frac{AC}{CD}[/tex]
Hence,
[tex]\frac{12.8}{4}=\frac{4}{CD}[/tex]
cross multiply
4 × 4 = 12.8 CD
16 = 12.8CD
divide both sides by 12.8
CD = 16 / 12.8
CD = 1.25 ft
BD = 1.25 + 12.8 = 14.05 ft
Therefore, the front of the base is 1.25 ft and the total base is 14.05 ft.
