The variance for waiting times for patients who are discharged after receiving treatment is more, so waiting times for patients who are discharged after receiving treatment is more variable.
What is variance?In probability and statistics, variance is the actual value of the squared variation of a stochastic process from its mean value. Informally, variance calculates the degree to which a random group of numbers deviates from the mean value.
Another essential tool, the measurement of variance is equal to the square of the standard deviation.
Since the variance for waiting times for patients who are discharged after receiving treatment is more, so waiting times for patients who are discharged after receiving treatment is more variable.

What is subtraction and addition ?In mathematics, subtraction is an operation which means taking away a few portions of the group or few things from a whole part.
For example, if we take 4 pencils out of 10 then remaining pencils are 6
so this process is called subtraction.
And opposite operation of subtraction is known as addition, which means in addition, few portion provided to the whole part.

If a 42 gal hot water tank holds 350 lb of water, what weight of water will a 59 gal tank hold?
A 59 gal tank hold will hold lb of water.
(Round to the nearest whole number as needed.)
A 59 gal water tank hold will hold 492 lb of water.
How much water would a 59 gal tank hold?The first step is to determine how many lb of water a 1 gal hot water tank can hold. In order to determine this value, divide 350 by 42.
Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.
Weight of water in a 1 gal water tank = 350 / 42 = 8.333 lb
Now, multiply the value gotten in the previous step by 59.
Weight of water in a 59 gal water tank = 8.333 x 59 = 492 lb

What is an Equilateral Triangle?A triangle is said to be equilateral if each of its three sides is the same length.
In the well-known Euclidean geometry, an equilateral triangle is also equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others.
Given, Triangle QRS is an equilateral triangle.
QR is seventeen more than twice x ---> QR = 17 + 2x
RS is 19 less than six times x, ---> RS= 6x - 19
And QS is one less four times x, ---> QS = 4x -1
We have to find x and measure of each side.

Point T is at (-2,5). What are the coordinates of point T after R y axis o R axis
The coordinates of point T' after Ry-axis is (2, 5) and the coordinates of point T' after Rx-axis is (-2, -5). The solution has been obtained by using the concept of reflection.
What is reflection?
In geometry, a reflection is referred to as a flip. In a reflection, the shape is reflected. An image will reflect over a line known as the line of reflection.
We are given a point T(-2, 5)
In order to find the coordinates of the reflection of point in the y-axis, we need to change the sign of abscissa i.e., x-coordinate and retain the ordinate i.e., y-coordinate.
So, we get the image of (-2 , 5) as (2, 5)
Thus, the coordinates of point T' after Ry-axis is (2, 5).
When we reflect across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.
So, we get the image of (-2 , 5) as (-2, -5).
Thus, the coordinates of point T' after Rx-axis is (-2, -5).
Hence, the coordinates of point T' after Ry-axis is (2, 5) and the coordinates of point T' after Rx-axis is (-2, -5).

Note that the best description for the graph is a > 4 is "A vertical solid line at (4,0) with the shading to the right of the line." (Option B)
What is the rationale for the above answer?Note that the inequality means that a is greater than 4. This means that the end value 4 is not included.
To graph the inequality " > " a dashed line is used. The inequality does not contain any y - value in it.
Hence, it has only one vertical line at a> 4 and is shaded for all values of a greater than 4.
Thus, the graph that fits the inequality is a vertical dashed line, shaded to the right of the line.

A study suggest 14.7% of all four digit personal identification numbers, or PIN codes, have a repeating digits format such as 2525. Assuming this to be true, if the PIN codes of four people are selected at random, what is the probability that at least one of them will have repeating digits?
The probability that at least one of the codes will have repeating digits is 0.4712.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Here, The probability of a pin being repeated is 14.7%
⇒ 14.7/100
After Eliminating the decimal point;
⇒ 14.7/100 = 147/1000
Hence,
The probability that a pin, if selected will have a repeating digit format = 147/1000
The probability of a pin not having repeating digits format is,
⇒ 1 - 147/1000
⇒ 853/1000
If four codes are selected at random (without replacement), the probability that all four of the codes will not have repeating digits format is,
⇒ (853/1000) x (852/999) x (851/998) x (850/997)

A square piece of cloth with an area of 324 square inches is folded in half twice to form the napkin shown. What is
the area of the folded napkin?
The area of the napkin will be 162.5 inches².
What is the area of a square?The area of a square is -
{A} = Side x Side
Given is that a square piece of cloth with an area of 324 inches² is folded in half twice to form the napkin.
The area of the cloth is -
{A} = 324
Let the side of the square cloth be {a}. So, we can write -
a² = 324
a = √324
{a} = 18 ... Eq { 1 }
The diagonal of the square will be the base length of the napkin (in the form of triangle). So, we can write -
d² = a² + a²
d² = 2a²
d² = 648
d = √648
{d} = 25.5 inches ... Eq { 2 }
The height would be -
h = d/2
h = 25.5/2
{h} = 12.75
The area of the napkin would be -
1/2 x d x h
1/2 x 25.5 x 12.75
162.5 inches²
Therefore, the area of the napkin will be 162.5 inches².

The mass of a radioactive substance follows a continuous exponential decay model, with the decay rate parameter 4% per day. A sample of this radioactive substance has an initial mass of 2.05 kg. Find the mass of the sample after four days. Round your answer to two decimal places.
The mass of the sample after four days is 1.75 kg.
How to find the mass of the sample after four days?The decay rate for a radioactive substance follows the exponential decay formula:
m(t) = m₀ * e^(-kt),
where m₀ is the initial mass, m(t) is the mass at time t, k is the decay rate parameter, and e is the base of the natural logarithm.
Given that the initial mass of the sample is 2.05 kg and the decay rate parameter is 4% per day, the formula becomes:
m(t) = 2.05 * e^(-0.04t).
To find the mass after four days, we substitute t = 4:
m(4) = 2.05 * e^(-0.04 * 4)
