P(Q) = 12/17
P(R) = 3/8
If Q and Rare independent events, find the PQ and R).
Answer:
9/34

P(QnR) = P(Q) * P(R)
= 12/17 * 3/8
= 9/34
A cylinder has a height of 6 meters and a radius of 3 meters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
169.56 m³
Step-by-step explanation:
» Concepts
The volume of a cylinder is how much space there is inside the cylinder. The formula to find the volume is πr²h, where r = radius and h = height. Once you get the volume, you have to add <unit>³.
» Application
We are given the radius as three meters and the height as six meters; we also have to use π as 3.14. Now, we just have to plug in these values into the aforementioned formula.

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 60% pure antifreeze. The company wants to obtain 240 gallons of mixture that contains 15% pure antifreeze . How many gallons of water and how many gallons of the premium antifreeze solutin must be mixed?
An equation is formed of two equal expressions. The amount of premium antifreeze and the water that should be mixed are 60 gallons and 180 gallons, respectively.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the amount of premium anti-freeze solution mixed be represented by x, while the amount of water mixed be represented by y.
Since the total mixture should be 240 gallons, therefore,
x + y = 240
Solving for y,
y = 240 - x
Given the percentage of pure antifreeze, the mixture should contain is 15%. Therefore, we can write,
60%x + 0%y = 15%(240)
0.60x = 0.15(240)
x = 60 gallons
Now substitute the value of x in the first equation,
y = 240 - 60 = 180 gallons
Hence, the amount of premium antifreeze and the water that should be mixed are 60 gallons and 180 gallons, respectively.

Answer:
128 cubes can fit in.
Step-by-step explanation:
We are given: Volume of rectangular prism = 2 units³ and Cube with edge = 1/4 unit
We must find: The number of cubes that can fill the prism
Firstly, find the volume of 1 cube:
Volume = 1/4 x 1/4 x 1/4
Volume = 1/64 units³
Next find the number of cubes that can go into the prism:
Number of cubes = 2 ÷ 1/64
Number of cubes = 128
Therefore 128 cubes can fit in.
There is a 2 kg book lying on a table. A 64 N force is applied to the book at a 120° angle from horizontal and moves the book 3 meters in the horizontal direction. How much work was done?
Answer:
156.32 joules
Step-by-step explanation:
In this case, we know the force of 64 N and the distance of 3 m. We also know that there is a 120°angle between the angle of the direction of applied force and the direction of motion. So plugging these values into our handy equation yields:
W = 64(3)cos(120)= 156.32 Joules
So the 64 N force at a 120° angle did 156.32 joules of work moving the book 3 meters.

A balloon artist claims the probability a randomly selected balloon pops while being molded is 0.10 and that balloons pop independent of other balloons. Part A. If we select a random sample of 3 balloons, what’s the probability that all of them pop while being molded?
Work Shown:
(0.10)^3 = (0.10)*(0.10)*(0.10) = 0.001
Answer:
0.001
Step-by-step explanation:
This can be modeled as a binomial distribution as:
There is a fixed number (n) of trialsEach trial is either a success or failureAll trials are independentThe probability of success (p) is the same in each trialThe variable is the total number of successes in the n trialsLet "success" be the balloon popping.
⇒ trials (n) = 3
⇒ probability of success (p) = 0.10
To find the probability that all 3 of the balloons pop, use the binomial distribution with x = 3:
[tex]\begin{aligned} \displaystyle P(X=x) & =\binom{n}{x} \cdot p^x \cdot (1-p)^{n-x}\\\\\implies P(X=3) & =\binom{3}{3} \cdot 0.1^3 \cdot (1-0.1)^{3-3}\\ & = 1 \cdot 0.001 \cdot 1\\ & =0.001 \end{aligned}[/tex]

Let us first consider how many sides this figure has:
⇒ it has 6 sides
Now to find the supposed sum of all the angles added up together for a hexagon, must use:
⇒ [tex]Formula =(n-2)*180[/tex]
n: # of sidesLet's plug in the number of sides:
[tex]Sum_.of_.angles=(6-2)*180=720[/tex]
Therefore all the angles of a hexagon must equal 720 degrees:
[tex]x + 90 + 110+160+90+140=720\\x + 590=720\\x = 130[/tex]
The value of x is 130.
Answer: 130

Answer:
4. A. y = -3x - 2
5. B. ¹/₃
Step-by-step explanation:
General form of a linear equation: y = mx + b
(where m is the slope and b is the y-intercept)
Question 4
From inspection of the graph, the y-intercept is at y = -2
The slope is the change in y divided by the change in x, so we can see that for every change of 1 x-value, the y-value decreases by 3 units.
Therefore, the slope is -3
So the equation of the line is y = -3x - 2
Question 5
Referring to the general form of the linear equation quoted above,
for equation y = ¹/₃x + 4
slope = ¹/₃y-intercept = 4What is the factored form of the expression x^2-2x-15?
Answer:

Step-by-step explanation:

True or false? The graph represents a function
Answer:
B. False
Step-by-step explanation:
To determine if a graph represents a function, you can use the vertical line test. A graph is a function if no vertical line intersects the graph at more than one point. In this graph, a line can intersect the graph at more than one point, therefore, it is not a function.
