What is ProbabilityThe likelihood that something will occur is known as the probability. Because we don't know how something will turn out, we might talk about the probability of one result or the potential for several outcomes. The study of events that fit into a probability distribution is known as statistics. The best example for understanding probability is flipping a coin:
There are two possible outcomes—heads or tails.
Given;Number of purple marble=16
Number of blue marble=12
Number of white marble=14
Number of brown marble=6
The Probability is =[tex]\frac{12+14+6}{16+12+14+6}[/tex] × [tex]\frac{14}{16+12+14+6}[/tex]

show that T<0,2> (0,1). Is T<0,2> (x,y) = D3 (x,y) a true statement for any point (x,y)? Why or why not.
Answer:
To show that T<0,2> (0,1), we need to evaluate the transformation T at the point (0,1) and check if the result is in the range of T.
T<0,2> (0,1) means that the transformation T takes the point (0,1) in the input space to a point in the output space that has coordinates (0,2).
Let's evaluate T at (0,1):
T<0,2> (0,1) = D3(0,1) + (0,1)
= (0+0, 3+1)
= (0, 4)
The output point (0,4) is not equal to (0,2), which means that T<0,2> (0,1) is false. Therefore, T<0,2> does not map the point (0,1) to (0,2).
To determine if T<0,2> (x,y) = D3 (x,y) is a true statement for any point (x,y), we need to check if the transformation T always equals the function D3.
T<0,2> (x,y) = (x, 3+y)
D3(x,y) = (x,y,3)
Since T and D3 have different ranges (T has a range of R^2 and D3 has a range of R^3), the statement T<0,2> (x,y) = D3(x,y) is not true for any point (x,y).
Therefore, we cannot equate T<0,2> and D3, and the statement T<0,2> (x,y) = D3 (x,y) is false for any point (x,y).

Using the p-value given, are the results significant at a 1% level? p-value = 0. 802
No, the result is not significant at 1 percent level for the p-value of 0.802.
Results are significant at a certain level,
Compare the p-value to the significance level (known as alpha).
The significance level is typically set at 0.05 or 0.01.
Here, the p-value is 0.802, which is much larger than 0.01.
This implies here we cannot reject the null hypothesis at a 1% significance level.
Or , the result is not statistically significant at a 1% level.
If the significance level was 5% that is equal to 0.05.
The result would not be significant at 5% level either.
If the significance level was 10% which is equal to 0.10.
Then the result would be significant as the p-value is less than 0.10.
Therefore, for the given p-value 0.802 result is not significant at 1%.

How do find volume of a solid that is a cylinder with a hemispherical hole cut from the top of it with the shaded rim 3 inches thick height is 12 in and part of hemisphere is a triangle with hypotenuse side 10 in
The volume of the solid is 284π/3 cubic inches.
To find the volume of the solid, we need to break it down into simpler shapes and then calculate their volumes separately.
The solid is made up of a cylinder and a hemispherical hole cut from the top of it. Let's first calculate the volume of the cylinder. The height of the cylinder is given as 12 inches and the radius can be calculated as half of the hypotenuse of the triangle (which is 10 inches). Therefore, the radius of the cylinder is 5 inches.
The formula for the volume of a cylinder is Vcylinder = πr^2h, where r is the radius and h is the height. Substituting the values, we get:
Vcylinder = π(5^2)(12) = 300π cubic inches
Now, let's calculate the volume of the hemispherical hole. The rim of the hole is 3 inches thick, which means the radius of the hole is (5 - 3) = 2 inches. The volume of a hemisphere is given by the formula Vhemisphere = (2/3)πr^3.
Substituting the values, we get:
Vhemisphere = (2/3)π(2^3) = 16π/3 cubic inches
Now, the volume of the solid can be found by subtracting the volume of the hemispherical hole from the volume of the cylinder:
Vsolid = Vcylinder - Vhemisphere
Vsolid = 300π - 16π/3
Vsolid = 284π/3 cubic inches
Therefore, the volume of the solid is 284π/3 cubic inches.

Suppose sin θ = - 3/5, sin ɸ = 20/29 Moreover, suppose θ is in Quadrant IV and ɸ is in Quadrant l. Find the following. sin(θ + ɸ) = ____ cos(θ + ɸ) = ____
sin(θ + ɸ) = 17/145 and cos(θ + ɸ) = 144/145.
Suppose sin θ = -3/5, sin ɸ = 20/29. Moreover, suppose θ is in Quadrant IV and ɸ is in Quadrant l. We can find sin(θ + ɸ) and cos(θ + ɸ) by using the following formulas: sin(θ + ɸ) = sin θ cos ɸ + cos θ sin ɸ and cos(θ + ɸ) = cos θ cos ɸ - sin θ sin ɸ.
First, we need to find cos θ and cos ɸ. Since θ is in Quadrant IV, cos θ is positive. We can use the Pythagorean identity, sin² θ + cos² θ = 1, to find cos θ:
cos² θ = 1 - sin² θ
cos² θ = 1 - (-3/5)²
cos² θ = 1 - 9/25
cos² θ = 16/25
cos θ = √(16/25)
cos θ = 4/5
Similarly, since ɸ is in Quadrant l, cos ɸ is also positive. We can use the Pythagorean identity to find cos ɸ:
cos² ɸ = 1 - sin² ɸ
cos² ɸ = 1 - (20/29)²
cos² ɸ = 1 - 400/841
cos² ɸ = 441/841
cos ɸ = √(441/841)
cos ɸ = 21/29
Now we can plug in the values of sin θ, sin ɸ, cos θ, and cos ɸ into the formulas for sin(θ + ɸ) and cos(θ + ɸ):
sin(θ + ɸ) = sin θ cos ɸ + cos θ sin ɸ
sin(θ + ɸ) = (-3/5)(21/29) + (4/5)(20/29)
sin(θ + ɸ) = -63/145 + 80/145
sin(θ + ɸ) = 17/145
cos(θ + ɸ) = cos θ cos ɸ - sin θ sin ɸ
cos(θ + ɸ) = (4/5)(21/29) - (-3/5)(20/29)
cos(θ + ɸ) = 84/145 + 60/145
cos(θ + ɸ) = 144/145
Therefore, sin(θ + ɸ) = 17/145 and cos(θ + ɸ) = 144/145.

If the coordinates of point I are (9, 12), what is the value of cos(G), sin(G), and tan(G) for triangle GHI? Explain your reasoning.
Answer:
cos G = 3/5
sin G = 4/5
tan G = 4/3
Step-by-step explanation:
I(9, 12)
GH = 9
HI = 12
(GI)² = 9² + 12²
GI = 15
For <G:
opp = HI = 12
adj = GH = 9
hyp = GI = 15
cos G = adj/hyp = 9/15 = 3/5
sin G = opp/hyp = 12/15 = 4/5
tan G = opp/adj = 12/9 = 4/3
Step-by-step explanation:
remember the triangle in a circle, when you learned about sine, cosine and the other trigonometric functions ?
this looked the same way, just that the circle was the norm-circle with radius 1.
here, now, the radius is larger, so every function line is also multiplied by the actual radius.
but the principles are the same.
sine is the up/down leg of the right-angled triangle.
cosine is the left/right leg.
tangent is sine/cosine.
I = (9, 12)
so, Pythagoras gives us the radius (line GI) :
GI² = GH² + HI² = 9² + 12² = 81 + 144 = 225
GI = sqrt(225) = 15
sin(G) × GI = HI
sin(G) × 15 = 12
sin(G) = 12/15 = 4/5 = 0.8
cos(G) × GI = GH
cos(G) × 15 = 9
cos(G) = 9/15 = 3/5 = 0.6
tan(G) = sin(G)/cos(G) = 4/5 / 3/5 = (4×5)/(5×3) =

Use either method to simplify the complex fraction. ((1)/(f^(3))-(1)/(a^(3)))/((1)/(f^(2))-(1)/(a^(2)))
To simplify the complex fraction ((1)/(f^(3))-(1)/(a^(3)))/((1)/(f^(2))-(1)/(a^(2))), we can use the common denominator method.
Step 1: Find the common denominator for the numerator and denominator of the complex fraction. The common denominator for the numerator is (f^(3))(a^(3)) and the common denominator for the denominator is (f^(2))(a^(2)).
Step 2: Multiply each term in the numerator and denominator by the common denominator to get rid of the fractions.
Numerator: ((1)(a^(3))-(1)(f^(3)))/(f^(3))(a^(3))
Denominator: ((1)(a^(2))-(1)(f^(2)))/(f^(2))(a^(2))
Step 3: Simplify the numerator and denominator by combining like terms.
Numerator: (a^(3)-f^(3))/(f^(3))(a^(3))
Denominator: (a^(2)-f^(2))/(f^(2))(a^(2))
Step 4: Divide the numerator and denominator by the common factor (f^(2))(a^(2)).
Simplified fraction: (a-f)/(f^(1))(a^(1))
Step 5: Simplify the final fraction by canceling out the common factors.
Final answer: (a-f)/(fa)
Therefore, the simplified complex fraction is (a-f)/(fa).

elizabeth buys a package of 360 marbles. she gives away 216 of the marbles. what percent of the marbles did elizabeth give away?
Answer:
Elizabeth gave away 216 marbles out of a total of 360 marbles.
To find the percentage of marbles that Elizabeth gave away, we can use the formula:
percentage = (part/whole) x 100%
where "part" is the number of marbles Elizabeth gave away, and "whole" is the total number of marbles.
So, plugging in the values we have:
percentage = (216/360) x 100%
percentage = 0.6 x 100%
percentage = 60%
Therefore, Elizabeth gave away 60% of the marbles.
