A ski gondola carries skiers to the top of a mountain. Assume that the total weights of adult skiers (including their equipment) are normally distributed with a mean of 200 lb and a standard deviation of 40 lb. Further assume that the gondola can carry a maximum of 25 skiers and has a maximum load limit of 5,000 lb. If the gondola is full, it will be overloaded if the mean total weight of the skiers exceeds 5,000 lb / 25 skiers = 200 lb/skier. If the gondola is filled with 25 randomly selected skiers, what is the probability that it will be overloaded? (Round your answer to three decimal places; add trailing zeros as needed.)
If the gondola is filled with 25 randomly selected skiers, the probability that it will be overloaded is; 50%
How to find the mean weight from normal distribution?The formula to find the maximum mean weight of passengers is;
Maximum mean weight = Load limit ÷ number of passengers
We are given;
Load limit = 5000 lb
Maximum number of passengers = 25
Thus;
Maximum mean weight of passengers = 5000 ÷ 25 = 200lb
Let us find the z-score:
z = (max value - mean) / st. dev

write the equation of a line perpendicular to 12y=2x+10 and passing though the point (-2,-1)
The equation of the line perpendicular to 12y = 2x + 10 and passing though the point (-2,-1) is y = -6x -7.
Writing the equation 12y = 2x + 10 in slope intercept form, we get,
y = (1/6)x + 5/6
The slope of the line is 1/6.
We know that,
Product of slope of two lines perpendicular to each other = -1.
Let the slope of the line perpendicular to the given line be m.
Hence, we can write,
m*(1/6) = -1
m = -6
Let the line perpendicular to the given line be y = mx + c.
It is given that the line perpendicular to the given line goes through (-2,-1).

A list of fixed fees for services recorded on the encounter form is called the Superbills.
The purpose of encounter forms, often referred to as super bills, is to "document services performed by recording the diagnostic and procedure codes, which serve as the foundation for billing and receipt of payment for services." Every time a patient or customer receives a service, the provider records that service, often into medical claims software that may automate much of the subsequent procedure.
This technique entails coding (procedure codes and, if necessary, diagnostic codes), billing/invoicing, and/or transmission to the patient's or client's insurance provider. For the client's health and treatment plans as well as for proper billing, it is crucial to make sure that the appropriate information is documented. This is why encounter forms are such a crucial component of healthcare.

write an equation of the line passing through the point (-20, 4) that is perpendicular to the line 2x+5y=10
Equation of the line passing through the point of (-20, 4) and perpendicular to the line [(2x + 5y) = 10] will be [2y = (5x + 108)].
As per the question statement, a line passes through the point of (-20, 4) and is perpendicular to the line [(2x + 5y) = 10].
We are required to determine the equation of the above-mentioned line.
To solve this question, we need to know about the formula to express the point-slope form of a line, which goes as, [(y - y₁) = m(x - x₁)],
where (x₁, y₁) is a point through which the line passes, and "m" is the slope of the line.
Also, we need to know about the mathematical fact that, the product of the slopes of two perpendicular lines equate to (-1), i.e., if (m₁ and m₂) are the slopes of two perpendicular lines, then [(m₁ * m₂) = (-1)].
Converting [(2x + 5y) = 10] into the point-slope form of line, we get,
(2x + 5y) = 10
or, [5y = {(-2x) + 10}]
or, [y = {(-2/5)x + 2}]
Therefore, Slope of the line [(2x + 5y) = 10] is (-2/5).
Hence, slope of the line perpendicular to [(2x + 5y) = 10] is [-1/(-2/5)], i.e.,
Slope of the line perpendicular to [(2x + 5y) = 10] is (5/2).
Now, using [m = (5/2)] and (x₁, y₁) as (-20, 4), equation of the line will be
[(y - 4) = (5/2){x - (-20)}]
or, [(y - 4) = (5/2)(x + 20)]
or, [(y - 4) = (5/2x) + 50]
or, [2(y - 4) = 5x + 100]
or, [(2y - 8) = (5x + 100)]
or, [2y = (5x + 108)]

Answer: see answers below
Step-by-step explanation:
F(x) is bascially the y
the absolute value means any numbers that you use for x when substituted into x-2 will always be a positive number even if x-2 is negative as with any number 3 or greater, or any number -3 or less.
for the values that are 0, 1, 2, 3, 4 or 0, -1, -2 the answer for f(x) will be a negative number. All other numbers positive or negative for x will result in a positive answer.
So you need to graph your line with an arrow on each end to show it goes to infinity. in your chart you choose a number for x, and the f(x) number (which is equivalent to the y number for purposes of graphing.
I cannot draw on her a graph for you because I don't have that ability without an app for that.
here are some sample points for your chart. THe first number in each parenthesis is x and the second is f(x)
(-1, -2), (-2, -1), (0, -3), (-3, 0), (1, -4), (2, -5), (3-4), (4,-3), (5-2), (6, -1) All other numbers positive or negative for x will result in f(x) being positive.
You only need two sets of points to put on the graph to draw the line through.
So negative values for f(x) can only be -1, -2, -3, -4, -5. x can include all negative numbers through infinity.
Positive will include all positive numbers through infinity for x and f(x).
F(x) cannot decrease beyond -5. x can decrease all numbers through infinity.

–4i, 4i

The non real roots of the polynomial x³ – 7x² + 15x – 25 = 0 are; 1 + 2i, 1 – 2i
What is the non - real root?
Non real roots are simply imaginary roots.
We are told that the real roots of the equation x³ – 7x² + 15x – 25 = 0 is 5.
Now, it means that (x - 5) is a factor of the given polynomial. Thus, we can factorize the polynomial as;
(x - 5)(x² - 2x + 5) = 0
Now, to find the non - real roots, we will use quadratic formula on (x² - 2x + 5) to get;
x = [-(-2) ± √((-2)² - (4 * 1 * 5))]/2(1)
x = (2 ± √(-16))/2

In Mrs. Brown’s 75% percent of the class likes to dance .
What are mathematics operations?
A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
Given:
number of students in Mrs. Brown’s class = 24
number of students likes to dance = 18
Then to find the percent of the class likes to dance we divide 18 by 24 and multiply with 100:
percent of the class likes to dance = (18/24) x 100
percent of the class likes to dance = 75%

The means are the same and the standard deviations are different.
There are two lists given for which the means and the standard deviations need to be compared. So we first find the mean and standard deviation of each list one-by-one using the formulas,
Mean = (1/n)∑x
Variance = [(1/n)∑x²]- mean²
Standard deviation = √variance
List A
x: 1 2 3 4 5 6
x²: 1 4 9 16 25 36
n = 6
Mean = (1/6)[1+2+3+4+5+6] = 21/6 = 3.5
Variance = 1/6[1+4+9+16+25+36] - 3.5² = 15.167-12.25 = 2.917
Standard deviation = √2.917 = 1.71
List B
x: 2 3 3 4 4 5
x²: 4 9 9 16 16 25
Mean = 1/6(2+3+3+4+4+5) = 21/6 = 3.5
Variance = 1/6(4+9+9+16+16+25)-3.5² = 13.167 - 12.25 = 0.917
