27. Representative Sample? You want to determine the average number of classes skipped by
first-year students at a small college during a particular semester. State whether each of the
following samples is likely to be representative and explain why or why not.
Sample 1: 100 first-year students who belong to a sorority or fraternity
Sample 2: 100 first-year students who play a varsity sport
Sample 3: The first 100 first-year students whom you meet at the student union
Sample 4: 100 first-year students taking honors humanities,, courses
A sample is said to be representative if the selection made form have population is free of bias. Evaluating the selection criteria listed above :
Sample 1 will not likely be representative as students who do not belong to either a sorority or fraternity are automatically exempted from the selection. Sample 2 will not likely be representative because not all students play a varsity sport, hence students who do not play a varsity sport won't have a chance of being selected. Sample 3 is a convenience sampling technique, they often exhibit sampling bias hence, sample 3 is not representative of the population. Sample 4 will not likely be representative as students taking other courses aside humanities have no chance of being selected.Therefore, all the sampling methods are not representative of the population of first year student.

The polynomial of degree 4, P ( x ) , has a root of multiplicity 2 at x = 1 and roots of multiplicity 1 at x = 0 and x = − 2 . It goes through the point ( 5 , 336 ) . Find a formula for P ( x ) . P ( x ) =___
Show your work
We want to find a polynomial given that we know its roots and a point on the graph.
We will find the polynomial:
p(x) = (183/280)*(x - 1)*(x - 1)*(x + 2)*x
We know that for a polynomial with roots {x₁, x₂, ..., xₙ} and a leading coefficient a, we can write the polynomial equation as:
p(x) = a*(x - x₁)*(x - x₂)...*(x - xₙ)
Here we know that the roots are:
x = 1 (two times)x = 0x = -2Then the roots are: {1, 1, 0, -2}
We can write the polynomial as:
p(x) = a*(x - 1)*(x - 1)(x - 0)*(x - (-2))
p(x) = a*(x - 1)*(x - 1)*(x + 2)*x
We also know that this polynomial goes through the point (5, 336).
This means that:
p(5) = 336
Then we can solve:
336 = a*(5 - 1)*(5 - 1)*(5 + 2)*5
336 = a*(4)*(4)*(7)*5
336 = a*560
366/560 = a = 183/280
Then the polynomial is:
p(x) = (183/280)*(x - 1)*(x - 1)*(x + 2)*x

What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have
Number of dried beans = 10/3 cups
The number of 1/3 cup servings can be found by dividing the total number of cups of dried beans by 1/3.
The number of 1/3 cup servings:
= Number of dried beans cups ÷ 1/3
= 10/3 ÷ 1/3
= 10/3 x 3/1
= 10 cups servings

Angle A = 133 degrees
47 degrees and angle A are supplementary angles/a linear pair, which means that they add up to 180.
180 - 47 = 133
Angle B = 15 degrees
The sum of the interior angles in a triangle is 180.
a + 32 + b = 180
133 + 32 + b = 180
b = 15
Angle D = 58 degrees
32 degrees and angle D are complementary angles, which means that they add up to 90.
90 - 32 = 58
Angle C = 75 degrees
The sum of the interior angles in a triangle is 180.
c + d + 47 = 180
c + 58 + 47 = 180
c = 75

Zayn puts garland around a square window. He uses 888 meters of garland.
What is the height of the window?
Answer:
222 meters
Step-by-step explanation:
Zayn puts a total of 888 meters of garland around a square window.
Because a square has all equal sides, divide the amount of garland he used by 4 to find how much is used per side:
888 ÷ 4 = 222
So, the height of the window is 222 meters.

The population P of a small town, measured in hundreds, is modeled by the inverse of the function P−1(t) = 10ln(50t − 1000), where t is measured in years. Find the equation to model the population and determine its initial value.
P = 5t +100 where P(0) = 100
P = 1/50 In(0.1t)+20
P = 1/500e^t + 20
P = 1/50e^0.1t + 20
Using the inverse function, it is found that the equation is:
[tex]P(t) = \frac{e^{0.1t}}{50} + 20[/tex]
It's initial value is 20.
---------------------------
We want to find the inverse of:
[tex]y = P^{-1}(t) = 10\ln{50t - 1000}[/tex]
To do this, we exchange y and t, and isolate y.
Then:
[tex]10\ln{50y - 1000} = t[/tex]
[tex]\ln{50y - 1000} = \frac{t}{10}[/tex]
[tex]e^{\ln{50y - 1000}} = e^{0.1t}[/tex]
[tex]50y - 1000 = e^{0.1t}[/tex]
[tex]50y = e^{0.1t} + 1000[/tex]
[tex]y = \frac{e^{0.1t} + 1000}{50}[/tex]
[tex]y = \frac{e^{0.1t}}{50} + \frac{1000}{50}[/tex]
[tex]P(t) = \frac{e^{0.1t}}{50} + 20[/tex]
It's initial value is:
[tex]P(0) = \frac{e^{0.1(0)}}{50} + 20 = 0.02 + 20 = 20.02[/tex]

Age of President G.H.W. Bush is 37.
What is Unitary Method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Age of President Bush = 54,
So, Age of President Clinton
=(54/2) + 14
=27+14
=41

Sally and her husband, Ahmed, together earned a total of $203,300 in taxable income last year. Using the tax table, what do they owe in federal income taxes? Enter your answer rounded to the nearest dollar, such as: $42,536
Answer:
$37,141
Step-by-step explanation:
The applicable line of the tax table is ...
$28,765+24% of the amount over $168,400
If A represents the amount of taxable income, this simplifies to ...
$28,765 +0.24(A - 168,400) = $28,765 +0.24A -40416 = 0.24A -$11,651
For their income of 203,300, Sally and Ahmed owe ...
0.24×203300 -11651 = 48792 -11651 = 37141
They owe $37,141.

Answer:
a) 5
b) 9
Step-by-step explanation:
The lines by the side decide absolute value, meaning distance from zero. for question A, simply add the integers to get -5. With the absolute value lines surrounding the question, you must make the answer 5 instead of -5 to show the distance from zero. In easier words, absolute value is just the positive number of an integer. For question B, the absolute value is surrounding just the -7, making it a positive 7. So, you simply just add 7 + 2 for question B, getting 9.
