Answer:
1 over 16 is not the same as 16.
1 over 16 is a fraction, which means that it represents a part of a whole. It can be written as 1/16, which means one part out of a total of sixteen equal parts.
On the other hand, 16 is a whole number, which represents a quantity of sixteen units.
So, 1/16 is not equal to 16.

QUESTION 1
Joe's Pizza Company faces a demand for its pizzas which obeys the "law of demand." This means if Joe lowers the price he charges
per pizza
His profit will rise.
He will sell more pizzas.
His profit will fall.
He will sell fewer pizzas.
If Joe lowers the price he charges per pizza, he will sell more pizzas. option B
Why would he sell more?To sell more pizza, Joe must decrease the price he charges per unit. The law of demand dictates that when a product's cost decreases, its quantity demanded rises resulting in an increased sales volume.
It follows then that if Joe reduces his pizza prices more people will be inclined to purchase it creating this increase in sales . Nonetheless, whether Joe’s profit will rise or diminish depends on the extent of the rise in sales compared to the lowering of the price.
Even if there is a reduction in the price of every pizza, if the resultant sales volume is significant enough, Joe’s profit margin could still experience a positive turn.

What is the median high daily temperature, in degrees Fahrenheit, in the city?
For the given data set of temperatures, the median temperature is 72.5 degree Fahrenheit.
In order to find the median temperature, we first need to arrange the temperatures in order from lowest to highest:
The temperatures arranged in order is : {66, 70, 72, 72, 73, 75, 79, 81}
There are 8 temperatures in total, which is an even-number, so the median will be the average of fourth and fifth day temperature.
In this case, the temperature of the fourth day is 72, and fifth day is 73,
The average will be = (72+73)/2 = 72.5,
Therefore, the median high daily temperature in the city is 72.5 degrees Fahrenheit.

Graph the function f(x) = 14(0.87)x. Does this function show growth or decay? What is the equation of the asymptote? Growth; y = 0 Growth; y = 14 Decay; y = 0 Decay; y = 14
The truth statements about the function f(x) = 14(0.87)^x is Growth; y = 0
Does the function show growth or decay?From the question, we have the following parameters that can be used in our computation:
f(x) = 14(0.87)^x
An exponential function is represented as
y = ab^x
Where
a = initial value
b = growth/decay factor
In this case, the exponential function is a decay function
This means that
The value of b is less than 1 i.e.
b = 0.87 and 0.87 < 1
Hence, the function is a decay function
What is the equation of the asymptote?Recall that
f(x) = 14(0.87)^x

The mapping of the function f(x) given as 3x⁴ - 4x³ + 3x² - 5x - 3 is define at;
-3, f(-3) = 390 and at 4, f(4) = 537
What is a functionA function is a rule that defines a relationship between one variable. It is the mapping whose codomain is the set of real numbers
By substitution:
For x = -3;
f(-3) = 3(-3)⁴ - 4(-3)³ + 3(-3)² - 5(-3) - 3
f(-3) = 3(81) + 4(27) + 3(9) + 15 - 3
f(-3) = 243 + 108 + 27 + 15 - 3
f(-3) = 390
For x = 4;
f(4) = 3(4)⁴ - 4(4)³ + 3(4)² - 5(4) - 3
f(4) = 3(256) - 4(64) + 3(16) - 20 - 3
f(4) = 768 - 256 + 48 - 20 - 3
f(4) = 537
Therefore, the mapping of the function f(x) = 3x⁴ - 4x³ + 3x² - 5x - 3 for the values of x: -3 and 4 we have the results 390 and 537 respectively.

A map shows the vertices of a campsite are (25,10), (25,-5), (-5,-5), and (-5,10). The vertices of your tent are (0,-3), (0,6), (10,6), and (10,-3). The coordinates are measured in feet. What percent of the campsite is not covered by your tent?
The percent of the area that is not covered is 80 percent
How to calculate the area that is not coveredIn mathematics area is defined as the absolute or total space that an object or shape occupies. It is usually measured using centimeters, cm ² square or the use of meter square m ².
area of tent
= (10 - 0) * (6 - (-3))

The area of the campsite would be:
(25 - (-5) x (10 - (-5))

The length of the curve y = 5 - 4x, -2 ≤ x ≤ 2, is 4√(17).
What is the length of the curve?To use the arc length formula, we need to find the derivative of the curve y = 5 - 4x:
y' = -4
Then, we can use the arc length formula:
L = ∫[a,b] √(1 + (y')^2) dx
where a and b are the limits of integration. In this case, a = -2 and b = 2.
L = ∫[-2,2] √(1 + (-4)^2) dx
= ∫[-2,2] √(17) dx
= √(17) * [x]_(-2)^(2)
= 4√(17)
So the length of the curve y = 5 - 4x, -2 ≤ x ≤ 2, is 4√(17).
To check this answer, we can note that the curve is a line segment with endpoints (-2, 13) and (0.75, 1), and we can calculate its length using the distance formula:
L = √((0.75 - (-2))^2 + (1 - 13)^2)
L = √(18.25 + 144)
L = √(162.25)
L = 4√(17)
This matches our previous answer, so we can be confident that the length of the curve is 4√(17).

Jaswat set out to walk a distance of 12 Km. After walking for 1 1/2 hours at a speed of
6 Km/h, he had to slow down to steady pace of 4 Km/h , which he maintained till the
end of the journey. How long did he take to complete the journey?
Answer: 2 hours 15 minutes
Step-by-step explanation:
To solve this problem, we need to use the formula:
distance = speed x time
First, let's calculate the distance Jaswat covered in the first 1 1/2 hours:
distance = speed x time
distance = 6 Km/h x 1.5 h
distance = 9 Km
So, Jaswat covered 9 Km in the first 1 1/2 hours. He still had to cover 12 Km - 9 Km = 3 Km.
Now, we need to calculate the time Jaswat took to cover the remaining 3 Km at a speed of 4 Km/h:
distance = speed x time
3 Km = 4 Km/h x time
time = 3 Km / 4 Km/h
time = 0.75 hours = 45 minutes
Therefore, Jaswat took 1 1/2 hours + 45 minutes = 2 hours 15 minutes to complete the journey.

The lodge has 420 skis. Predict the number of skis that are likely to be defective.
A ski lodge inspects 80 skis and discovers four that are faulty. The skis that are likely to be defective are 21.
It is assumed that there are 80 skis, four of which are faulty.
As a result, the total number of outcomes is 80.
Positive outcomes = 4
Let [tex]E_{1}[/tex] represent the event of selecting a faulty. As a result, the likelihood of selecting a defective ski is expressed mathematically as follows.
[tex]E_{1}[/tex] = Favorable case of defective / Total number of skis
= 4 / 80
= 1 / 20
=0.05
Skis will be discovered in 5% of cases.
So, the event of choosing a defective is 4 / 80.
If the total number of skis is 420, then the number of defective skis will be:
4 / 80 × 420

what is the measure of an angle if it is 590 less than six times its own supplement
This is a word problem involving supplementary angles. To solve it, we need to follow these steps:
Identify the given information and the unknown quantity. In this problem, we are given that an angle is 590 less than six times its own supplement. The unknown quantity is the measure of the angle.
Write an equation that relates the given information and the unknown quantity. We can use the fact that supplementary angles are two angles with a sum of 180°1. Let x be the measure of the angle. Then its supplement is 180 - x. The equation is:
x=6(180−x)−590
Solve the equation for the unknown quantity. We can simplify and rearrange the equation to get:
xx7xxx=6(180−x)−590=1080−6x−590=490=7490=70
Therefore, the measure of the angle is 70°.
Find the next three numbers in the pattern: 2,0,6,−4,10,−8,
The next "three-umbers" in the pattern "2,0,6,-4,10,-8,..." are 14, -12, and 18.
To find the next three numbers in the pattern 2, 0, 6, -4, 10, -8, we need to analyze the pattern and identify the rule for it.
The pattern seems to be alternating between adding and subtracting the "odd-multiples" of 2.
The pattern is as follows : 2 - (2×1) = 0,
0 + (2×3) = 6,
6 - (2×5) = -4,
-4 + (2×7) = 10,
10 - (2×9) = -8,
Using this rule, we can find the next three numbers in the pattern as follows:
Add 22 because : -8 + (2×11) = 14,
Subtract 26 because : 14 - (2×13) = -12,
Add 30 , because : -12 + (2×15) = 18,
Therefore, the next three numbers in the pattern are 14, -12, and 18.

What is a polynomial function?In Mathematics and Geometry, a polynomial function can be defined as a mathematical expression which comprises intermediates (variables), constants, and whole number exponents with different numerical value, that are typically combined by using mathematical operations.
This ultimately implies that, a polynomial graph touches the x-axis at real zeros, roots, solutions, x-intercepts, and factors with even multiplicities.
In this context, we can reasonably and logically deduce that the real zeros of a polynomial function are all of the values (x-intercepts) on the x-coordinate that makes this polynomial function equal to zero and it is non-existent on the graph above.
