The perimeter of this triangular plot of land can be represented by the expression 3x2 + 10x + 20.
6x + 11
2x2 + 9
Write a polynomial that represents the measure of the third side of the plot of land.
Answer:
x^2+4x
Step-by-step explanation:
(3x^2+10x+20)-(6x+11) = 3x^2+4x+9
(3x^2+4x+9)-(2x^2+9) = x^2+4x
The polynomial that represents the measure of the third side of the plot of land is x² + 4x.
What is Perimeter?Perimeter of a straight sided figures or objects is the total length of it's boundary.
Given two sides of a triangular plot of land.
6x + 11
2x² + 9
Perimeter = 3x² + 10x + 20
Perimeter of a triangle = Sum of the three sides
Let A represents the third side.
6x + 11 + 2x² + 9 + A = 3x² + 10x + 20
2x² + 6x + 20 + A = 3x² + 10x + 20
A = 3x² + 10x + 20 - (2x² + 6x + 20)
A = x² + 4x
Hence the measure of the third side is x² + 4x.

N=
M=
Answer:
n = 6
m = 6√3
Step-by-step explanation:
Reference angle = 30°
Opposite = n
Adjacent = m
Hypotenuse = 12
✔️To find n, apply the trigonometric ratio, SOH:
Sin 30° = Opp/Hyp
Sin 30° = n/12
n = Sin 30° × 12
n = ½ × 12 = 6
✔️To find m, apply the trigonometric ratio, CAH:
Cos 30° = Adj/Hyp
Cos 30° = m/12
m = Cos 30° × 12
m = √3/2 × 12 (cos 30 = √3/2)
m = √3 × 6
m = 6√3

The store is selling lemons at $0.41 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy
enough lemons to make three 9-inch lemon pies, each requiring half a cup of lemon juice?
Answer: It costs about 7.32 to buy enough lemons.
Step-by-step explanation:
Each lemon yields 2 tablespoons, which is equal to one fluid ounce.
8 fluid ounces = one cup, 4 fluid ounces = half a cup
Four lemons will provide juice for one pie.
Cost of one pie = 4 0.61 = 2.44
Cost of three pies = 2.44 3 = 7.32

reduce 105 in the ratio 3:5
9514 1404 393
Answer:
39.375 : 65.625
Step-by-step explanation:
The meaning of "reduce" in this context is unclear. We assume you want to divide the quantity 105 into parts that have a ratio of 3 : 5. Then the smaller part will be 3/(3+5) = 3/8 of the total; the larger part will be 5/8 of the total.
3/8 × 105 = 39 3/8
5/8 × 105 = 65 5/8
The divided quantities are ...
39.375 : 65.625
A researcher wishes to be 95% confident that her estimate of the true proportion of individuals who travel overseas is within 4% of the true proportion. Find the sample necessary if, in a prior study, a sample of 200 people showed that 40 traveled overseas last year. If no estimate of the sample proportion is available, how large should the sample be
Answer: If in a prior study, a sample of 200 people showed that 40 traveled overseas last year, then n= 385
If no estimate of the sample proportion is available , then n= 601
Step-by-step explanation:
Let p be the prior population proportion of people who traveled overseas last year.
If p is known, then required sample size = [tex]n=p(1-p)(\dfrac{z^*}{E})^2[/tex]
z-value for 95% confidence = 1.96
E = 0.04 (given)
[tex]p=\dfrac{40}{200}=0.2[/tex]
[tex]n=0.2(1-0.2)(\dfrac{1.96}{0.04})^2=384.16\approx385[/tex]
Required sample size = 385
If p is unknown, then required sample size = [tex]n=0.25(\dfrac{z^*}{E})^2[/tex]
, where E = Margin of error , z* =critical z-value.
z-value for 95% confidence = 1.96
E = 0.04 (given)
So, [tex]n=0.25(\dfrac{1.96}{0.04})^2=600.25\approx601[/tex]
Required sample size = 601.

The game of Scrabble has 100 tiles. The diagram shows the number of tiles for each letter and the letter's point value. One tile is drawn from Scrabble's 100 tiles. Find the probability of selecting an O or a V.
Answer:
10%
Step-by-step explanation:
In the image attached below, we can see that there are
8 tiles of letter O
2 tiles of letter V
This means that there are 10 total tiles of the letters that you want to get (O and V). Since there are a total of 100 tiles we need to divide this value by 100 to get the probability of getting one of these tiles.
10 / 100 = 0.10 or 10%
Finally, we can see that the probability of selecting a O or a V is 10%
Answer: 8% of O, 2% of V
Step-by-step explanation: There are 8 O tiles and 2 V tiles

Of interest is to determine the mean age of students at the time they take the comprehensive exam for all students enrolled in graduate programs that require students to take comprehensive exams. A simple random sample of 31 students enrolled in graduate programs was selected, and the age of each student when they took the comprehensive exam was recorded. The mean age at the time of taking the comprehensive exam for this sample of 31 students was 27.5 years with a standard deviation of 2.9 years; there were no outliers in the sample that would lead one to suspect heavy skewness in the distribution. If appropriate, use this information to calculate and interpret a 98% confidence interval for the mean age of students at the time they take the comprehensive exam for all students enrolled in graduate programs that require students to take comprehensive exams. Use this information to answer questions 3-5
Answer:
The 98% confidence interval for the mean age of students at the time they take the comprehensive exam for all students enrolled in graduate programs that require students to take comprehensive exams is between 26.2 and 28.8 years. This means that we are 98% sure that the mean age of all students taking the exam is between 26.2 and 28.8 years.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 31 - 1 = 30
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 30 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 2.457
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.457\frac{2.9}{\sqrt{31}} = 1.3[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 27.5 - 1.3 = 26.2 years
The upper end of the interval is the sample mean added to M. So it is 27.5 + 1.3 = 28.8 years
The 98% confidence interval for the mean age of students at the time they take the comprehensive exam for all students enrolled in graduate programs that require students to take comprehensive exams is between 26.2 and 28.8 years. This means that we are 98% sure that the mean age of all students taking the exam is between 26.2 and 28.8 years.
A jar contains 3 blue marbles, 4 yellow marbles, and 3 green marbles.
What is the probability of randomly choosing a yellow marble, replacing
it, and then choosing a blue marble?
Answer:
3/25
Step-by-step explanation:
There are 10 total marbles
P(yellow) = yellow/total = 4/10 = 2/5
We replace it so there are 10 marbles
P(2nd marble blue) = blue /total = 3/10
Multiply the two probabilities together
P(yellow, replace, blue) =2/5*3/10 = 3/25

Answer:
restrictions exclude parts of the domain where the function is not defined. On a graph, they are holes, or vertical asymptotes.the denominator might be (x² -4)they are different in the same way that adding and multiplying numerical fractions are differentStep-by-step explanation:
1. In general, restrictions on rational functions refer to values of the variable that make the denominator zero. The function will be undefined in that case. On a graph, such a location will show up as a "hole" or a vertical asymptote.
__
2. If ±2 are excluded from the domain, we expect factors of (x-2)(x+2) in the denominator. That is, the denominator will have a factor of (x²-4). (There may be other factors that do not have real zeros.)
__
3. A rational expression is a fraction the same as any other. The usual rules of addition, subtraction, multiplication, and division apply. For addition and subtraction, it can be useful to identify a common denominator. For multiplication and division, that is not so essential.
