A distribution is given as X~ U(0, 12).What is the theoretical mean?
The theoretical mean of the uniform distribution between 0 and 12 is given as follows:
6.
What is the uniform probability distribution?It is a distribution with two bounds, given by a and b, in which each possible outcome is equally as likely.
The bounds for this problem are given as follows:
a = 0 and b = 12.
As each outcome is equally as likely, the mean of the distribution is equals to the mean of the bounds, hence:

An office block has five floors (ground, 1, 2, 3 and 4), all connected by a lift. When it goes up
to any floor (except 4), the probability that after it has stopped it will continue to rise is 3/4.
When it goes down to any floor (except the ground floor), the probability that after it has
stopped it will continue to go down is 1/4. The lift stops at any floor it passes.
The lift is currently at the first floor having just descended. Calculate the probability of
these events.
a Its second stop is the third floor.
b Its third stop is the fourth floor.
c Its fourth stop is the first floor.
Answer:
Step-by-step explanation:
a) The second stop is the third floor:
The first stop is the first floor, so the probability of going up from the first floor is 3/4.
The next stop is the third floor, so the probability of going up from the second floor (which is the first floor in this scenario) to the third floor is 3/4.
The probability of both events happening is the product of the individual probabilities: (3/4) * (3/4) = 9/16.
b) The third stop is the fourth floor:
The first stop is the first floor, so the probability of going up from the first floor is 3/4.
The next stop is the third floor, so the probability of going up from the first floor to the third floor is 3/4.
The next stop is the fourth floor, so the probability of going down from the third floor to the fourth floor is 1/4.
The probability of all three events happening is the product of the individual probabilities: (3/4) * (3/4) * (1/4) = 3/16.
c) The fourth stop is the first floor:
The first stop is the first floor, so the probability of going up from the first floor is 3/4.
The next stop is the third floor, so the probability of going up from the first floor to the third floor is 3/4.
The next stop is the fourth floor, so the probability of going down from the third floor to the fourth floor is 1/4.
The next stop is the first floor, so the probability of going down from the fourth floor to the first floor is 3/4.
The probability of all four events happening is the product of the individual probabilities: (3/4) * (3/4) * (1/4) * (3/4) = 9/64.
Would sorting the tiles with positive coefficients and tiles with negative coefficients together help to simplify an expression that involves all tiles? Explain.
Yes, it is possible to make an expression including all tiles simpler by grouping together the tiles with negative coefficients and the tiles with negative coefficients.
Negative coefficients: What are they?Simply put, negative coefficients are coefficients with negative values. A negative coefficient can be anything like -8 in the term -8z or -11 in the term -11xy. The result of multiplying the variables by the integer is negative.
What happens to a negative exponent's coefficient?A negative exponent signifies a very small number: The decimal in the coefficient is shifted eleven positions to the left as a result. A decimal number must also be moved in order to be expressed in scientific notation.

Write an equation for the function graphed
Answer:
y = |x - 3| - 1
Step-by-step explanation:
The vertex of the absolute value function graphed is (3, -1). The formula for absolute value is y = a |x - h| + k, where (h, k) is the vertex. The a stretches the graph, although this graph isn't stretched. So a is 1, which is the same as multiplying by 1. Plugging 3 as h and -1 as k into the formula results in y = |x - 3| - 1.

Write a couple of paragraphs describing how you can determine the values of x that a) make
the rational function 0, and b) the values of x where the rational function is undefined:
f(x) = x²-2x+1
4x+5
The required paragraphs regarding with given expression f(x) = x²-2x+1/4x+5 have been explained later in the section.
A rational expression is a fraction in which the numerator and denominator are polynomials.
Here,
a) To determine the values of x that make the rational function f(x) equal to 0, we need to solve the equation:
x² - 2x + 1 = 0
Next, we can factor the quadratic on the left-hand side of the equation:
(x - 1)(x - 1) = 0
The quadratic is a perfect square, and we can see that it is equal to 0 when x = 1. So, the value of x that makes the rational function 0 is x = 1.
b) To determine the values of x where the rational function f(x) is undefined, we need to look for values of x that would make the denominator, 4x+5, equal to 0. If the denominator is equal to 0, then we would be dividing by 0, which is undefined.
So, we set the denominator equal to 0,
4x + 5 = 0
4x = -5
x = -5/4
Therefore, the value of x where the rational function is undefined is x = -5/4.

What is an absolute value inequality?
The non-negative value of a real number x without regard to its sign is known as its absolute value or modulus in mathematics and is indicated by the symbol |x|.
An expression using absolute functions and inequality signs is known as an absolute value inequality. One example of an absolute value inequality with a larger than symbol is the statement |x + 3| > 1.
1) length x = 4.2 cm with a tolerance of 0.01 cm
Absolute value inequality is:
|x - 4.2| ≤ 0.01
This can be written as:
x - 4.2 ≤ 0.01x ≤ 4.21
x - 4.2 ≥ - 0.01x ≥ 4.19
2) length x = 3.5 cm with a tolerance of 0.2 cm
Absolute value inequality is:
|x - 3.5| ≤ 0.2
This can be written as:
x - 3.5 ≤ 0.2x ≤ 3.7
x - 3.5 ≥ - 0.2x ≥ 3.3

The table lists several points on a polar graph.
θ 0 pi over 6 pi over 3 pi over 2 2 pi over 3 5 pi over 6 π
r 4 2 −2 −4 −2 2 4
Which of the following graphs is represented by the table?
Answer:
r = 4 cos(2θ)
See the attached image for a graph.
Step-by-step explanation:
The points given by the table are in the graph of a cosine rose with 4 petals whose amplitudes are 4.
For the equation r = a cos(nθ), a is the amplitude of the petals (4), and n is half the number of petals, as there are an even number of petals (4/2 = 2).
Hence,
r = 4 cos(2θ)
Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower
class limits, and the upper class limits.
minimum = 10, maximum = 68, 7 classes
The class width is ?
The lower class limits are ?
The upper class limits are ?
Answer:
Step-by-step explanation:
213232131123123123123123
1. To find the class width, we first need to find the range of the data, which is the difference between the maximum and minimum values: 68 - 10 = 58. Then, we divide the range by the number of classes to get the class width: 58 / 7 = 8.29. However, we will round up to the nearest whole number, so the class width is 9.
2. The lower class limits are 10, 19, 28, 37, 46, 55, and 64, since we add the class width to the lower limit of each previous class to find the lower limit of the next class.
3. The upper class limits are 18, 27, 36, 45, 54, 63, and 68, since we add the class width to the lower limit of each class to find the upper limit of that class.

If a truck carrying 3 tons of wheat unloads 1, 000 pounds, what is the weight of the
wheat still in the truck?
Answer: the weight of the wheat still in the truck is 5000 pounds.
Step-by-step explanation:
Here are the steps to calculate the weight of the wheat still in the truck:
Convert the weight of the unloaded wheat to tons. To convert from pounds to tons, divide by 2,000:
1000 lbs / 2000 lbs/ton = 0.5 tons
Subtract the weight of the unloaded wheat from the original weight:
3 tons - 0.5 tons = 2.5 tons
Convert the answer back to pounds:
2.5 tons * 2000 lbs/ton = 5000 lbs
Therefore, the weight of the wheat still in the truck is 5000 pounds.
