Using theoretical probability, the probability of selecting green ball is 3/11, not selecting green ball is 8/11, selecting orange ball is 6/11 and not selecting orange ball is 5/11.
In the given question,
A bag has 2 red, 3 green, and 6 orange balls.
So total number of balls = 2+3+6 = 11
We have to find the theoretical probability.
(a) We have to find the theoretical probability of selecting green ball.
P(G) = Total number of green balls/Total number of balls
P(G) = 3/11
Hence, the probability of selecting green ball is 3/11.
(b) Now we have to find the theoretical probability of not selecting green ball.
Except green ball there is having red and orange i.e.
Total remaining balls except green = 2+6 = 8
P(G) = Total number of balls except green balls/Total number of balls
P(G) = 8/11
Hence, the probability of not selecting green ball is 8/11.
(c) Now we have to find the theoretical probability of selecting orange ball.
P(G) = Total number of orange balls/Total number of balls
P(G) = 6/11
Hence, the probability of selecting green ball is 6/11.
(d) Now we have to find the theoretical probability of not selecting orange ball.
Except orange ball there is having red and green balls i.e.
Total remaining balls except orange = 2+3 = 5
P(G) = Total number of balls except orange balls/Total number of balls
P(G) = 5/11
Hence, the probability of not selecting orange ball is 5/11.

Terry needs 40 gal of a 40% acid solution. The only available acid solutions are 25% and 80% acid. How much of each should she mix together (to the nearest gallon)?
Terry should mix 29 gallons of the 25% acid solution and 11 gallons of the 80% acid solution
How to determine the amount of each acid to be mixed together?Given: 40% acid and 80% acid solutions
Terry needs 40 gal of a 40% acid solution
Let x represent the amount of the 25% acid solution required in gal
Thus, the amount of the 80% acid solution required will be (40-x) gal
The amount of acid in these solutions is 0.25x + 0.8(40-x)
Since Terry wants exactly 40% or 0.4 of 40 gallons i.e. 0.4×40 gallons
The amount of acid in these solutions will be:
0.25x + 0.8(40-x) = 0.4×40 Solve for x
0.25x + 32-0.8x = 16
0.8x-0.25x = 32-16
0.55x = 16
x = 16/0.55 = 29 gallons
40-x = 40 -29 = 11 gallons
Therefore, the amount of the 25% acid solution required is 29 gallons
and the amount of the 80% acid solution required is 11 gallons. So she should mix 29 gallons and 11 gallons respectively

first reach an altitude of 60 meters?
3.4 seconds
-8 seconds
2.2 seconds
13 seconds
The arrow first reach an altitude of 60 meters is 13 seconds.
A General Rule for Solving Equations
Simplify each side of the equation by removing parentheses and combining like terms.Use addition or subtraction to isolate the variable term on one side of the equation.Use multiplication or division to solve for the variable.Finding the value of the given equation's unknown variables is a step in the equation-solving process.The value of the variable satisfies the requirement that the two expressions are equal. When a linear equation has one variable, there is only one solution; when there are two variables, there are two solutions. A quadratic equation's solution yields two roots. To solve an equation, a variety of techniques and steps are used.h (t) = -2.1t² +32t-0.03 ---(i)
The arrow first reach an altitude of 60 meters:
h(t) = 60 -- (ii)
Equate the (i) and (ii)
60 = -2.1t² +32t-0.03
2.1t² - 32t + 0.03 + 60 = 0

e. Explain why time is not a function of height in the bouncing ball experiment.
The value of velocity is [tex]v = 7.67\frac{m}{s}[/tex].
The coefficient of restitution is the ratio of the final to initial speed between two bodies after the collision. While a value of 1 indicates a perfectly elastic collision, a value of 0 indicates a perfectly inelastic collision.
The first option is
We can find the displacement by using the area under the graph, which is equal to the displacement. The area of the triangle can be found using the formula below.
[tex]Area = \frac{1}{2} . base . length[/tex]
[tex]Area = 0.5m.50m.50. = 1250 m^{3}[/tex]
The other option is
We use the conservation of energy. So, we equate the potential energy and the kinetic energy.
[tex]E_{pot} = E_{kin}\\ \\ m.g.h = \frac{1}{2}.m.v^{2}[/tex]
The mass is cancelled out in the above equation, and we re-arrange with respect to velocity.
[tex]v^{2} = 2.g.h\\ \\v = \sqrt{2.9.81\frac{m}{s^{2} }.3m } = 7.67\frac{m}{s}[/tex]
Hence the answer is the value of velocity is [tex]v = 7.67\frac{m}{s}[/tex].

A ABC has a right angle at C, BC = 9.2 centimeters, and mA = 63°.
What is CA?
In the right-angled triangle ABC, CA is 4.2cm.
What is a right-angled triangle? How to identify it?
Any angle that is a right angle or has one of its interior angles equal to 90 degrees is considered to be in a right-angled triangle. This triangle is also known as the right triangle or the 90-degree triangle for this reason. Trigonometry heavily utilizes the right triangle. In this article, let's learn more about this triangle.
By applying Pythagoras' theorem, one can determine whether a triangle has a right angle. If the squares of the triangle's two shorter sides equal the square of the hypotenuse, a right angle is present.
Solution explained:
A/Q, we have
BC = 9.2cm and m∠A = 63°
Using the tangent ratio formula (ratio of a side that is not the hypotenuse to a side that is near to an angle), we get
[tex]tanA = \frac{BC}{CA}[/tex]
tan 63° = [tex]\frac{9.2}{CA}[/tex]
CA = [tex]\frac{9.2}{1.96}[/tex] (tan 63° = 1.96)
CA = 4.687 ≅ 4.7cm
