QUICKKK PLEAZZEWrite two different expressions to represent the perimeter of this square. What can you conclude from the two expressions? Express your answer in two or more complete sentences.
The perimeter of the square can be expressed as either S+S+S+S or 4×S
How to write two different expressions to represent the perimeter of a square?
Perimeter is the distance around the edge of a shape. It can be found by adding up the side lengths of the shapes
Given: a square with a side length of S. Thus, the perimeter can be expressed as:
Perimeter = S + S + S + S = 4S
Since there are 4 equal sides each having a length of S. Thus, we can also write perimeter as:
Perimeter = 4 × S = 4S
Therefore, we can conclude the same expression are the same since they both have the same value of 4S

A closed top box with a square base is to have a volume of 4000 cubic inches. What are the dimensions that will minimize the amount of material used to build the box?.
The minimum dimensions to minimize the amount of material is 15.87 x 15.87 x 15.87 inch.
We need to know about the minimum function to solve this problem. The minimum function can be defined as the minimum value of the variable. It can be calculated by the derivative of the function. The minimum function can be written as
f'(s) = 0
where f'(s) is the derivative function
From the question above, the given parameter is
V = 4000 inch³
The cubic volume can be written as
s² x h = 4000
where s is the length of the base area and h is the height of the box.
the minimum value of the box refer to its surface area, hence
f(s) = 4sh + 2s²
f'(s) = 4h + 4s
4h + 4s = 0
h = s
It means that the length of the base area and the height must have the same dimension. The minimum volume should have a cube shape
V = s³
s³ = 4000
s = 15.87 inch

hospital records show that 16% of all patients are admitted for heart disease, 26% are admitted for cancer (oncology) treatment, and 8% receive both coronary and oncology care. what is the probability that a randomly selected patient is admitted for something other than coronary care? (note that heart disease is a coronary care issue.)
0.86 is the probability that a randomly selected patient is admitted for something other than coronary care.
What is probability ?
The likelihood that something will occur is the foundation of it. The justification for probability serves as the basic foundation for theoretical probability.A coin is tossed, for instance, and the theoretical likelihood of receiving a head is 1 in 2.Let H denotes the patients are admitted for heart disease.
Let C denotes the patients are admitted for cancer treatment.
We are given:
P(H) = 0.16
P(C) = 0.26
P( H ∩ C ) = 0.8
P(Hc ) = 1 - P(H) = 1 - 0.16 = 0.86

explain why it is reasonable to use a one-sample t confidence interval to estimate the population mean even though the population distribution is not approximately normal. (select all that apply.)
The general form of a Confidence Interval Estimate for a population mean is
Sample mean ± Critical Value × Standard Error of statistics.
Confidence intervals are one type of statistical interference. They allow us to range values where we can be relatively confident the true value will be. In this case, we are constructing a confidence interval for a population mean. For example: - Suppose that our sample has a mean of X bar = 10 and have constructed the 90% confidence interval.
From the above discussion, we get to know that:
It is reasonable to use a one sample t confidence interval to estimate the population mean since all freshman at a mid western university where surveyed.
It is reasonable to use a one sample t confidence interval to estimate the population mean since the sample size is at least 30.

Richard's Bakery recently spent a total of $594 on new equipment, and their average hourly operating costs are $5. Their average hourly receipts are $23. The bakery will soon make back the amount it invested in equipment. How many hours will that take? What would the total expenses and receipts both equal?
Answer:
33 Hours.
Step-by-step explanation:
Their hourly receipts are $23, and their hourly operating costs are $5. So you would subtract the hourly receipts from the hourly operating costs.
23 - 5 = 18
Then you would take the new number and divide the money spent on equipment by the money earned an hour.
594 / 18 = 33

What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The given coordinate of the point on the line is ; (-4, -5) and the slope is 7/4
Let the required equation of the line is
⇒ y - y₁ = m [x -x₁]
x₁ = -4, y₁ = -5 and m = 7/4
Substitute values in the equation, we get
y - (-5)= (7/4)(x - (-4))
y + 5 = (7/4)(x + 4)
y + 5 = (7/4)x + (7/4)4

What are the equation?a declaration that two mathematical expressions' values are equal (represented by the symbol =).
We get the equations as,
3.75x+4y=251.75
y=-0.93x+62.93---->equation(1)
x+y=64
y=-x+64------>equation (2)

For equation (1),
(0,62.93) and (67.66,0)
For equation (2),
(0, 64) and (64,0)
If we draw a graph we get 2 lines intersect at a point (24, 30).

Let sin A = 1/3, with A in quadrant II, and let cos B =3/4, with B in quadrant I. Find sin(A - B). Give an exact, simplified answer.
The Trigonometric function sin(A - B) = (3 - 2[tex]\sqrt{14}[/tex]) ÷ 12
What is trigonometry?The study of correlations between triangles side lengths and angles is known as trigonometry.In geometric figures, unknown angles and distances are derived from known or measured angles using trigonometric functions. The need to calculate angles and distances in disciplines like astronomy, mapmaking, surveying, and artillery range finding led to the development of trigonometry.The easiest way is to use the Pythagorean Identity to find both cos A and sin B. Then use the sum/difference angle identity for sine.
The trigonometric Pythagorean identity tells us that,
[tex]Sin^{2}[/tex]θ + [tex]cos^{2}[/tex]θ = 1
which follows directly from the geometric identity for right triangles and the fact that,
sinθ = y/r and cosθ = x/r
If r is the distance (x,y) is from the origin, then
[tex]x^{2}[/tex] + [tex]y^{2}[/tex] = [tex]r^{2}[/tex]
[tex](x/r)^{2}[/tex] + [tex](y/r)^{2}[/tex] = 1(divide both sides by [tex]r^{2}[/tex])
[tex]cos^{2}[/tex]θ + [tex]Sin^{2}[/tex]θ = 1
Anyway, if we know sin A (and which quadrant it ends in), we can solve for cos A and vice versa:
[tex]Sin^{2}[/tex]θ + [tex]cos^{2}[/tex]θ = 1
[tex](1/3)^{2}[/tex] + [tex]cos^{2}[/tex]θ = 1
⇒ cos A = [tex]\sqrt{1-(1/3)^{2} }[/tex] = [tex]\frac{2\sqrt{2}}{3}[/tex]
cosθ is always negative in this quadrant.
Therefore,
cos A = -[tex]\frac{2\sqrt{2} }{3}[/tex]
Similar reasoning can be done with cos B = [tex]\frac{3}{4}[/tex] to show that sin B = -[tex]\frac{\sqrt{7} }{4}[/tex]
Now that we have all the necessary elements, we can use the sum/difference angle identity:
Sin(A-B) = sin A cos B - cos A sin B
= ( [tex]\frac{1}{3}[/tex] × [tex]\frac{3}{4}[/tex] ) - ( (-[tex]\frac{2\sqrt{2} }{3}[/tex] ) × (-[tex]\sqrt{7[/tex]/4) )
= (3 ÷ 12) - (2[tex]\sqrt{14}[/tex] ÷ 12)
= (3 - 2[tex]\sqrt{14}[/tex]) ÷ 12
We get sin(A - B) = (3 - 2[tex]\sqrt{14}[/tex]) ÷ 12

.1116666 day/mi * 26.4 mi = 2.948 day ~ 2.9 days

A new car is purchased for \$14,000$14,000 and over time its value depreciates by one half every 5.5 years. What is the value of the car 18 years after it was purchased, to the nearest hundred dollars
Answer:
$1400
Step-by-step explanation:
You want the value of a car 18 years on if its initial value was $14,000 and its value is cut in half every 5.5 years.
Exponential modelThe value of the car can be modeled by the exponential equation ...
value = (initial value) × (growth factor)^(t/(growth period))
where "growth period" is the period applicable to the "growth factor."
ApplicationHere, the problem statement tells us ...
initial value = $14,000growth factor = 1/2growth period = 5.5 yearsSo, our exponential model is ...
value = 14,000·(1/2)^(t/5.5)
When t=18 years, this is ...
value = 14,000(1/2)^(18/5.5) = 14000(1/2)^(36/11) ≈ 14000·0.103469 ≈ 1449
The value after 18 years is about $1400.
