The shapes are the same, just one is sideways. They also have very similar measurements.
Step-by-step explanation:
Even so, when we check this we get:
(1 1/2 x 1 3/4) 7 = (3 x 1 3/4) 3 1/2
when simplified (solved) this is: 18 3/8 = 18 3/8
The probability that an egg on a production line is cracked is 0.01. Two eggs are selected at random from the production line. Find the probability that at least one egg is cracked. Write the entire decimal answer.
Answer:
[tex]P(X \geq 1)=1-P(X<1)= 1- P(X=0)[/tex]
[tex]P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801[/tex]
And replacing we got:
[tex] P(X \geq 1) = 1-0.9801 = 0.0199[/tex]
Step-by-step explanation:
Let X the random variable of interest "number of craked eggs", on this case we now that:
[tex]X \sim Binom(n=2, p=0.01)[/tex]
The probability mass function for the Binomial distribution is given as:
[tex]P(X)=(nCx)(p)^x (1-p)^{n-x}[/tex]
Where (nCx) means combinatory and it's given by this formula:
[tex]nCx=\frac{n!}{(n-x)! x!}[/tex]
And we want to find this probability:
[tex]P(x \geq 1)=1-P(X<1)= 1- P(X=0)[/tex]
And we can find the probability:
[tex]P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801[/tex]
And replacing we got:
[tex] P(X \geq 1) = 1-0.9801 = 0.0199[/tex]
4~ Please help. What is m∠LKE?
Answer:
the answer is 35 degrees
Step-by-step explanation:
The angle the diameter of a circle forms = 90 degrees
Therefore, angle ELK = 90 degrees
Sum of interior angles of a triangle = 180 degrees
Therefore, 55 deg + 90 deg + angle LKE = 180 deg
angle LKE = 180 - 145
LKE = 35 degrees

The volume of this cone is 376.8 cubic feet. What is the radius of this cone?
Use ≈ 3.14 and round your answer to the nearest hundredth
Height is 10ft
Answer:
The radius of the cone is 6 feets.
Step-by-step explanation:
We have,
Volume of the cone is 376.8 cubic feet
Height of the cone is 10 ft
It is required to find the radius of this cone. The formula of the volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]
r is radius of cone
[tex]r=\sqrt{\dfrac{3V}{\pi h}} \\\\r=\sqrt{\dfrac{3\times 376.8}{3.14\times 10}} \\\\r=6\ ft[/tex]
So, the radius of the cone is 6 feets.

Step-by-step explanation:
Divide both sides of the equation by c²
Factorise the polynomial x^3 - 5x^2 +2x +8, (x-4) is a factor.
Pllsss i need help ASAP! T^T
Answer:
x^3 - 5x^2 + 2x + 8
= (x^3 - 4x^2) - (x^2 - 4x) - (2x - 8)
= x^2(x - 4) - x(x - 4) - 2(x - 4)
= (x^2 - x - 2)(x - 4)
= [x(x - 2) + (x - 2)](x - 4)
= (x - 2)(x + 1)(x - 4)

Are they coterminal
Answer:
no
Step-by-step explanation:
To find coterminal angles for a given angle
add/ subtract 360° from it
Thus
135° + 360° = 495° or 135° - 360° = - 225°

what is the area of the parallelogram
A. 11in2
B. 22in2
C. 45in2
D. 60in2
Answer:
Step-by-step explanation:
Area of a parallelogram is base times height. So 15x4
It’s 60in^2
So D
Answer:
D. 60 inches^2
Step-by-step explanation:
The area of a parallelogram can be found using:
a=bh
We know that the height is 4 inches, and the base is 15 inches. Therefore, we can substitute 4 in for h and 15 in for b.
a=4*15
Multiply 4 and 15
a=60
Area is always units^2. We know the units are inches, therefore the area is:
60 inches^2, or choice D
The yearly cost in dollars, y, at a video game arcade based on total game tokens purchased, x, is y = y equals StartFraction 1 Over 10 EndFraction x plus 60.x + 60 for a member and y = y equals StartFraction 1 Over 5 EndFraction x. x for a nonmember. Explain how the graph of a nonmember’s yearly cost will differ from the graph of a member’s yearly cost.
Answer:
The members slope is flatter by half compared to the non-members slope. The graphs intersect at 600 tokens and $120. Until that point the cost for non-members is less than the cost for members. After 600 tokens the cost for members is less than the cost for non-members.
Step-by-step explanation:
I hope I have your equations correct:
Member:
y = 1/10x + 60
Non-Member:
y = 1/5x
The graph of a non-member yearly cost will have a slope of 1/5 and a y-intercept, of 0 while the graph of a member's yearly cost will have a slope of 1/10 and a y-intercept of 60 tokens.
How to solve graphs of straight lineAccording to the question;
For a member; y equals StartFraction 1 Over 10 EndFraction x plus 60.x + 60 for a member.For a member; y equals StartFraction 1 Over 10 EndFraction x plus 60.x + 60 for a member.For a non-member; y equals StartFraction 1 Over 5 EndFraction x.In essence; the mathematical equation for a member is;
y = (1/10)x + 60.For a non-member;
y = (1/5)x.Ultimately, the graph of a non-member yearly cost will have a slope of 1/5 and a y-intercept, of 0 while the graph of a member's yearly cost will have a slope of 1/10 and a y-intercept of 60 tokens.

Answer:
AB ≈ 7.83
Step-by-step explanation:
Using the sine ratio in the right triangle
sin50° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB }[/tex] = [tex]\frac{6}{AB}[/tex]
Multiply both sides by AB
AB × sin50° = 6 ( divide both sides by sin50° )

Quadrilateral ABCD is the result of a reflection of quadrilateral LMNO over the line. Which line segment in the image corresponds to NO in the pre-image? I want to say CD but not 100% sure. Only correct answers please. Very important. Working on it now
Answer:
CD
Step-by-step explanation:
Reflection is a rigid transformation which always create a congruent image of the original image or pre-image.If quadrilateral ABCD is the result of a reflection of quadrilateral LMNO over the line.
Then both the quadrilaterals are congruent.
To find the line segment in the image corresponds to NO in the pre-image, just check the order of the letters in the name of quadrilaterals.
Also, In reflection image and its pre-image are equidistant from the line of reflection
hence, CD is the line segment in the image corresponds to NO in the pre-image.

Answer:
incremental area
Step-by-step explanation:
Let width be representd by 'W'
Original Area = W × X
Original Area = WX
New width= W+10
New Area= X(W+10)
= WX + 10X
= Original Area + 10X
Here 10X is the incremental area
