Option B. 5 and one-third units. The value of a in triangle XYZ is 5 and two-thirds units. This is found using the Pythagorean theorem twice and solving for a.

To find the value of a, we can use the Pythagorean theorem in triangles WZY and WYX as follows:

In triangle WZY:

[tex]c^2 = 3^2 + (a + 4)^2[/tex]

In triangle WYX:

[tex]b^2 = 4^2 + a^2[/tex]

Since angle ZWX is a right angle, we can use the Pythagorean theorem in triangle ZWX as follows:

[tex]ZWX^2 = ZW^2 + WX^2[/tex]

We know that ZW = c and WX = b, so we have:

[tex]a^2 + b^2 = c^2[/tex]

Substituting[tex]c^2[/tex] in terms of a and simplifying, we get:

[tex]a^2 + b^2 = 25 + (a + 4)^2[/tex]

Expanding and simplifying, we get:

[tex]a^2 + b^2 = a^2 + 8a + 41[/tex]

Subtracting [tex]a^2[/tex] from both sides, we get:

[tex]b^2 = 8a + 41[/tex]

Substituting [tex]b^2[/tex] in terms of a in the equation [tex]a^2 + b^2 = c^2[/tex], we get:

[tex]a^2 + 8a + 41 = c^2[/tex]

Substituting[tex]c^2[/tex] in terms of a from the equation for triangle WZY, we get:

[tex]a^2 + 8a + 41 = 9 + (a + 4)^2/16[/tex]

Expanding and simplifying, we get:

[tex]16a^2 + 128a + 656 = 9a^2 + 50a + 97[/tex]

Simplifying further, we get:

[tex]7a^2 + 78a - 559 = 0[/tex]

Using the quadratic formula, we get:

[tex]a = (-78 ± sqrt(78^2 + 4(7)(559))) / 14[/tex]

a = (-78 ± sqrt(49379)) / 14

Since a represents a length in a triangle, it must be positive. Therefore, we have:

a = (sqrt(49379) - 78) / 14 ≈ 6.67

The snow that will be gotten daily of the line plot is redistributed equally will be 1/2.

A line plot, also known as a line graph, is a type of graph that displays information as a series of data points connected by straight lines. Line plots are often used to show how a particular variable changes over time or to compare two or more variables.

To create a line plot, you typically need to have a set of data points that represent the variable you want to graph. You then plot each data point on a graph, with the x-axis representing time or some other variable, and the y-axis representing the value of the variable you're graphing.

The snow that will be gotten daily of the line plot is redistributed equally will be:

The probability of each event is: P(A) = 0.34 P(B) = 0.66 P(C) = 0.89

What is Probability ?

Probability can be defined as ratio of number of favourable outcomes and total number of outcomes.

To find the cdf F(x) of X, we can use the following formula:

F(x) = P(X ≤ x) = ∑ P(X = k) for k ≤ x

So we have:

F(0) = P(X ≤ 0) = P(X = 0) = 0.11

F(1) = P(X ≤ 1) = P(X = 0) + P(X = 1) = 0.11 + 0.23 = 0.34

F(2) = P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.11 + 0.23 + 0.25 = 0.59

F(3) = P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.11 + 0.23 + 0.25 + 0.3 = 0.89

F(4) = P(X ≤ 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.11 + 0.23 + 0.25 + 0.3 + 0.35 = 1

So the cdf F(x) of X is:

F(x) = 0 for x < 0

F(x) = 0.11 for 0 ≤ x < 1

F(x) = 0.34 for 1 ≤ x < 2

F(x) = 0.59 for 2 ≤ x < 3

F(x) = 0.89 for 3 ≤ x < 4

F(x) = 1 for x ≥ 4

b. To calculate the probability of the events A = {fewer than two lines are in use}, B = {at least two lines are in use}, C = {between one and five lines, inclusive, are in use}, we can use the cdf F(x) that we just found.

P(A) = P(X < 2) = F(1) = 0.34

P(B) = P(X ≥ 2) = 1 - P(X < 2) = 1 - F(1) = 1 - 0.34 = 0.66

P(C) = P(1 ≤ X ≤ 5) = F(5) - F(0) = 1 - 0.11 = 0.89

Therefore, the probability of each event is: P(A) = 0.34 P(B) = 0.66 P(C) = 0.89

The transformation of the function G(x) in the form of y = +A| x - C| + D is -

y = 0.5| x + 1| + 0.5

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

To write the transformation of the function G(x) = 0.5|x+1| in the form y = +A |x - C| + D, we need to find the values of A, C, and D.

First, let's rewrite the given function in the form of |x - C| -

G(x) = 0.5 | x + 1| = 0.5| x - (-1)|

Comparing with the standard form y = A | x - C| + D, we have -

A = 0.5, C = -1

To find the value of D, we need to substitute a point on the graph of G(x) into the function and solve for D.

Let's use the point (-2, 1) -

G(-2) = 0.5|-2+1| = 0.5

So, we get D = 0.5.

Therefore, the transformation of the function is y = 0.5| x + 1| + 0.5.

How to find  total area under the normal distribution curve?

To find the total area under the normal distribution curve, we can use the standard normal distribution table or a calculator with a normal distribution function. We need to find the areas to the left and right of the given z-scores and add them together.

First, we can find the area to the left of z = -2.15 using the standard normal distribution table or a calculator with a normal distribution function. The area to the left of z = -2.15 is the same as the cumulative probability of a standard normal distribution with a z-score of -2.15. Using a standard normal distribution table or a calculator, we find this area to be 0.0158.

Next, we can find the area to the right of z = 1.62 using the standard normal distribution table or a calculator with a normal distribution function. The area to the right of z = 1.62 is the same as the complement of the cumulative probability of a standard normal distribution with a z-score of 1.62. Using a standard normal distribution table or a calculator, we find the complement to be 0.0526. Therefore, the area to the right of z = 1.62 is 1 - 0.0526 = 0.9474.

Finally, we can add the area to the left of z = -2.15 and the area to the right of z = 1.62 to find the total area under the normal distribution curve:

S = area to the left of z = -2.15 + area to the right of z = 1.62

S = 0.0158 + 0.9474

S = 0.9632

Therefore, the total area under the normal distribution curve is 0.9632.

Answer:

Let's call the three-digit number whose digits are all the same "n". We know that n must be between 111 and 999, inclusive.

Now let's consider a three-digit number x. We can write x as:

makefile

Copy code

x = 100a + 10b + c

where a, b, and c are the hundreds, tens, and one's digits of x, respectively. The sum of the digits of x is:

CSS

Copy code

a + b + c

If we subtract this sum from x, we get:

CSS

Copy code

100a + 10b + c - (a + b + c) = 99a + 9b

We want this to be equal to n, which means:

Copy code

99a + 9b = n

We know that n has three identical digits, so we can write:

makefile

Copy code

n = 111p

where p is a digit between 1 and 9. Substituting this into the equation above, we get:

CSS

Copy code

99a + 9b = 111p

11a + b = 37p

Since a and b are digits between 0 and 9, we can see that 37p must be between 0 and 99. The possible values of p are therefore 1, 2, and 3.

If p = 1, then 37p = 37, and we need to find two digits a and b such that 11a + b = 37. This gives us the solutions (a, b) = (3, 4) and (a, b) = (4, 3), which correspond to the numbers 343 and 434.

If p = 2, then 37p = 74, and we need to find two digits a and b such that 11a + b = 74. There are no such solutions since the largest possible value of 11a + b is 99.

If p = 3, then 37p = 111, and we need to find two digits a and b such that 11a + b = 111. This gives us the solution (a, b) = (10, 1), which corresponds to the number 1001. However, 1001 is not a three-digit number, so it does not count.

Therefore, the only two three-digit numbers that satisfy the conditions of the problem are 343 and 434. There are 2 such numbers.

Step-by-step explanation:

The piecewise function for f(x) is f(x) = x - 2, x ≥ 2; -x + 2, x < 2, So the correct answer is option C.

In mathematics, a function is a rule that assigns each element of a set (called the domain) to a unique element of another set (called the range). Functions are a fundamental concept in mathematics and are used to describe relationships between variables, as well as to model and solve a wide range of mathematical problems.

A function is typically denoted using a letter such as "f", and is defined by an equation or formula that specifies how the input (or domain) values are transformed into output (or range) values. For example, the function "f(x) = 2x + 1" assigns each input value "x" to an output value equal to twice the input value plus one.

The absolute value function f(x) = |x - 2| can be written as a piecewise function by separating it into two cases:

Case 1: x - 2 ≥ 0 or x ≥ 2

In this case, the expression inside the absolute value bars becomes x - 2, so f(x) = x - 2.

Case 2: x - 2 < 0 or x < 2

In this case, the expression inside the absolute value bars becomes -(x - 2) = -x + 2, so f(x) = -x + 2.

Therefore, the piecewise function for f(x) is:

f(x) =

x - 2, x ≥ 2

-x + 2, x < 2

So the correct answer is option C.
