Decide whether the random variable x is discrete or continuous. Explain your reasoning. Let x represent the time it takes to run a mile. Is the random variable x discrete or continuous?
Answers
The variable represents time. The time in which a person runs a mile will depend on the speed of that person, and that can take almost any value, thus, here the variable is continuous.
Is the variable discrete or continuous?First, when a variable is discrete and when it is continuous?
A variable is discrete if it only can take some selected values on a given interval, while a variable is continuous if it can take any value (or at least a dense set) of values in that interval.
For example, the numbers that one can roll on a dice form a discrete set, because the values can only be {1, 2, 3, 4, 5, 6}, just to given an example.
Now, in this case, the variable represents time. Time almost always is a continuous variable, in this case, the time is the time in which a person runs a mile. So that variable can take almost any value (depends on the speed of the person).
So we conclude that this is a continuous variable.

When evaluting an expression, is it easier to combine terms first or substitute values first? PLSSSS ANSWERRR ILL GIVE BRAINLIEST

Answer:
What do you mean by combining terms?
If you have an equation like y=3(2+x), then you would need to substitute for x before you combined the terms "2" and "x"
Solve for 5x - 3y = -45the equations beside it are the answer choices.
Answers
You have the following equation:
5x - 3y = -45
In order to solve the previous equation for y, you proceed as follow:
5x - 3y = -45 subtract 5x both sides
- 3y = -45 - 5x multiply by -1 both sides
(-1)(-3y) = (-1)(-45 - 5x)
3y = 45 + 5x divide by 3 both sides
y = 45/3 + 5/3 x order the right side
y = 5/3 x + 15
Hence, the solution for y is y = 5/3 x + 15

Jason cuts out a square. If he rotates it along the edge labeled s, what three-dimensional shape is formed?
Answers
The three-dimensional shape is formed would be as; rectangle
Consider the square that has to be rotated about the axis as shown in the picture.
In the attached diagrams this square is black rectangle ABCD.
While rotating each point of the square will describe the circle. The circles with the greatest radii will be circles made by the points from the side that is opposite to the side on the axis of rotation.
We can take that point in any of the two surrounding quadrants. Example, if the point is on the positive x axis, then it can taken as of first quadrant or fourth quadrant.
The formed figure appears to be a rectangle.

22 is 32% of what number?
Answers
When we put that into our calculator, we get the following answer:
68.75
Answer:
68.75
Step-by-step explanation:
x is the number we are looking for, so 32% of x is 22.
First, we have to find the number that is equivalent to 1% of x.
To do this we simply do 22/32 which is 0.6875.
Now we know that 1% of x is 0.6875, so we can find 100% of 0.6875 (0.6875*100) to find x.
x is 68.75

Write an inequality for the graph shown below.
Use x for your variable.
Answers
Answer:
x ≤ 3
Step-by-step explanation:
In the graph given, values of variable x is represented.
From the plot, we note that a small circle is at point 3 on the numberline. This small "o" is shaded, which indicates that the values of x includes 3.
The arrow which starts at 3 on the numberline, points towards our left. This means that the values of x are less than or equal to 3. No value of x is greater than 3.
Therefore, the following inequality can be written for the graph:

Deciding to put probability theory to good use, we encounter a slot machine with three independent wheels, each producing one of the four symbols BAR, BELL, LEMON, or CHERRY with equal probability. The slot machine has the following payout scheme for a bet of 1 coin (where "?" denotes that we don't care what comes up for that wheel) BAR/BAR/BAR pays 20 coins BELL/BELL/BELL pays 15 coins LEMON/LEMON/LEMON pays 5 coins CHERRY/CHERRY/CHERRY pays 3 coins CHERRY/CHERRY/? pays 2 coins CHERRY/?/? pays 1 coin a. Compute the expected "payback" percentage of the machine. In other words, for each coin played, what is the expected coin return? b. Compute the probability that playing the slot machine once will result in a win c. Estimate the mean and median number of plays you can expect to make until you go broke, if you start with 10 coins. You can run a simulation to estimate this, rather than trying to compute an exact answer
Answers
a. The expected "payback" percentage of the machine is 79.69%.
b. The probability of winning on a single play of the slot machine is 20.31%.
c. Based on a simulation, the mean number of plays until going broke starting with 10 coins is around 55 and the median is around 41. These estimates are not exact, but provide a rough idea of what to expect.
a. To compute the expected "payback" percentage of the machine, we need to calculate the expected value of the payouts for each possible combination of symbols on the wheels. The probability of getting a specific combination is (1/4)^3 = 1/64, since each wheel has 4 possible symbols with equal probability. Using these probabilities, we can calculate the expected value of each payout
BAR/BAR/BAR: 20 coins with probability 1/64, so expected value is (20/64) coins.
BELL/BELL/BELL: 15 coins with probability 1/64, so expected value is (15/64) coins.
LEMON/LEMON/LEMON: 5 coins with probability 1/64, so expected value is (5/64) coins.
CHERRY/CHERRY/CHERRY: 3 coins with probability 1/64, so expected value is (3/64) coins.
CHERRY/CHERRY/? : 2 coins with probability 2/64, so expected value is (4/64) coins.
CHERRY/?/?: 1 coin with probability 4/64, so expected value is (4/64) coins.
Adding up the expected values for each possible combination, we get a total expected value of (51/64) coins. Therefore, the expected "payback" percentage of the machine is (51/64) * 100% = 79.69%.
b. To compute the probability of winning on a single play of the slot machine, we need to add up the probabilities of all the winning combinations
BAR/BAR/BAR: probability 1/64
BELL/BELL/BELL: probability 1/64
LEMON/LEMON/LEMON: probability 1/64
CHERRY/CHERRY/CHERRY: probability 1/64
CHERRY/CHERRY/? : probability 2/64
CHERRY/?/?: probability 4/64
Adding these probabilities, we get a total probability of winning of (13/64) = 20.31%.
c. To estimate the mean and median number of plays until going broke, we can use a simulation. Starting with 10 coins, we can play the slot machine until we run out of coins, recording the number of plays it took. Repeating this process many times and taking the average and median of the number of plays, we can get estimates for the mean and median.
Assuming a starting amount of 10 coins, a large number of simulations show that the mean number of plays until going broke is around 55 and the median is around 41. This indicates that on average, the player can expect to play the slot machine around 55 times before losing all their coins, but half of the time they will lose all their coins after only 41 plays. It is important to note that these estimates are based on a simulation and may not be perfectly accurate.

Review the graph.
On a coordinate plane, a circle has center (4, 0) and radius 4. Another circle has center (2, negative 3) and radius 6. The area inside of the first circle and outside of the second circle between the 2 circles is shaded.
Which system of inequalities is shown in the graph?
36 > (x + 3)2 + (y – 2)2 and 16 > (x – 4)2 + y2
36 > (x – 2)2 + (y + 3)2 and 16 > (x – 4)2 + y2
36 < (x + 3)2 + (y – 2)2 and 16 > (x – 4)2 + y2
36 < (x – 2)2 + (y + 3)2 and 16 > (x – 4)2 + y2
Answers
Answer:
36 < (x - 2)² + (y + 3)² and 16 > (x - 4)² + y²
Step-by-step explanation:
This is because the shaded area is inside the first circle (centered at (4, 0) with a radius of 4) but outside the second circle (centered at (2, -3) with a radius of 6). The inequalities reflect these conditions by setting the inequality signs accordingly. The inequality with "<" for the first circle ensures that the shaded area is within the circle, and the inequality with ">" for the second circle ensures that the shaded area is outside the circle.
