The required probability that the marble is not yellow and not blue is 7/12. Option C is correct.
Given that,
A marble is drawn at random from a bag containing 2 blue marbles, 3 yellow marbles, and 7 orange marbles.
Probability can be defined as the ratio of favorable events to the total number of outcomes.
Here,
blue = 2
yellow = 3
orange = 7
The probability that the marble is not yellow and not blue,
= 1 - 2/12 - 3/12
= [12 - 2 - 3] / 12
= 7/12
Thus, the required probability that the marble is not yellow and not blue is 7/12. Option C is correct.

Step-by-step explanation:
Answer:
I think its b) y=2x-3
Step-by-step explanation:
The answers are all in slope-intercept form: y= mx+b. In slope-intercept form m represents the slope and b represents the y-intercept. (Its confusing, I know).
The slope here is 2/1 or 2. Considering rise/run we can see that the line goes up (rise) two (2) points and over (run) one (1).
Now we have y= 2x+b, we just need the y-intercept.
Looking at the y-axis, the line crosses at (0, -3). So the y-intercept is -3!
That gives us y=2x-3

find the length of the third side to the nearest 10th
Answer:
9.5
Step-by-step explanation:
Using the pythagorean theorem a^2+b^2=c^2, we can say that 3^2+b^2=10^2.
Simplify and you get 9+b^2=100. Subtract 9 from both sides and you get b^2=91. When you take the square root you get 9.53939... round to the nearest tenth and the missing side is 9.5.

The value of the trigonometric relation cot ( sin⁻¹ ( -1 ) ) = 0
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the trigonometric relation be represented as A
Now , the value of A is
A = cot ( sin⁻¹ ( -1 ) ) be equation (1)
On simplifying , we get
The value of ( sin⁻¹ ( -1 ) ) = -π/2
where sin (-θ) = -sin (θ)
So , A = cot ( -π/2 )
From the trigonometric relations ,
cot (-θ) = -cot (θ)
cot ( -π/2 ) = 0
Hence , the trigonometric relation is solved

Step-by-step explanation:
The name of the federal agency that regulates the investment industry is SEC. Therefore, option A is the correct answer.
What is the federal agency?Federal agencies are specialized government institutions created for a particular function, such as resource management, financial regulation of specific sectors, or matters of national security. Although a presidential order may also be used to establish these organisations at first, legislative action is usually required to establish them.
The Securities and Exchange Commission (SEC) was founded as an independent federal agency by the Securities Exchange Act of 1934. The Securities and Exchange Commission (SEC) is one of the most wide and powerful bodies, enforcing Securities legislation in the United States controlling the bulk of the securities business. In addition to other electronic securities markets and enterprises, it oversees stock exchanges, options markets, and options exchanges in the United States. It also regulates financial advisers who are not governed by the government.

Your math teacher asks you to calculate the height of the goal post on the football field. You and a partner gather the measurements shown. Find the height of the goal post, rounded to the nearest tenth of a foot.
Answer: The height of the goalpost is 41.6 feet (to the nearest tenth of a foot)
Step-by-step explanation: The figure shows an observer looking up at a goalpost at an angle of elevation of 61 degrees. The observer is 20 feet away from the base of the goalpost and he is standing 5.5 feet from the ground. This means the total height of the goalpost shall be an addition of the observer's height plus the calculated length of the portion of the goalpost as indicated by the right angled triangle.
We now have a right angled triangle, with one of the other two angles measuring 61 degrees and this shall be the reference angle. The side facing the reference angle is the opposite and is yet unknown. Also, the length from his position to the base of the goalpost is the adjacent (the side that lies between the right angle and one of the other two sides. To calculate the height,
Tan 61 = opposite/adjacent
Tan 61 = opposite/20
Tan 61 x 20 = opposite
1.8041 x 20 = opposite
36.082 = opposite.
Remember that the entire length of the goalpost includes the height of the observer (which is 5.5 ft). The height of the goalpost therefore is
Height = 5.5 + 36.082
Height = 41.582
The height of the goalpost rounded to the nearest tenth of a foot is
41.6 feet
The height of the goal post rounded to the nearest tenth is 41.6 ft
The situation forms a right angle triangle .
Properties of a right angled triangle:One of its angle is equals to 90 degreesThe sides and angle can be found using trigonometric ratios.The height of the goal post is the height of the person plus the height of the triangle formed.
Therefore, lets find the height of the triangle formed using trigonometric ratios,
tan 61° = opposite / adjacent
tan 61° = h / 20
cross multiply
h = 20 tan 61
h = 20 × 1.80404775527
h = 36.0809551054
Therefore,
height of the goal post = 36.0809551054 + 5.5 = 41.5809551054
height of the goal post ≈ 41.6 ft

racer had a bag of marbles he had 7 blue marbles 5 green marbles 5 red marbles and 1 yellow marble whta is the probrability of choosing a blue marble? i need the answer in fraction pls
The probability of choosing a blue marble is 7/18.
To find the probability of choosing a blue marble, we use the formula:
Probability = Number of favorable outcomes / Total number of possible outcomes
In this case, the number of favorable outcomes is 7 (because there are 7 blue marbles) and the total number of possible outcomes is 18 (because there are 7 blue marbles + 5 green marbles + 5 red marbles + 1 yellow marble). So the probability of choosing a blue marble is 7/18.
