Answer:
trinomial , degree 5
Step-by-step explanation:
9y^5 + y - 3y^3
Writing the polynomial in standard form (from biggest power to smallest)
9y^5 - 3y^3+ y
This has 3 terms so it is a trinomial
The highest power is 5 so it has degree 5
Martha is looking into investing a portion of her recent bonus into the stock market. While researching different companies, she discovers the following standard deviations of one year of daily stock closing prices.
Eye Remember Enterprises:
Standard deviation of stock prices
= $1.25 = $1.25
The Azure Travel Company:
Standard deviation of stock prices
= $9.73 = $9.73
Based on the data and assuming these trends continue, which company would give Martha a stable long-term investment?
A. The Azure Travel Company; the larger standard deviation indicates that The Azure Travel Company has less variability in its closing prices than Eye Remember Enterprises.
B. Eye Remember Enterprises; the smaller standard deviation indicates that Eye Remember Enterprises has less variability in its closing prices than The Azure Travel Company.
C. Eye Remember Enterprises; the smaller standard deviation indicates that Eye Remember Enterprises has a greater mean closing price than The Azure Travel Company.
D. The Azure Travel Company; the larger standard deviation indicates that The Azure Travel Company has a greater mean closing price than Eye Remember Enterprises.
Answer:
Based on the data and assuming these trends continue, the company that would give Martha a stable long-term investment is:
B. Eye Remember Enterprises; the smaller standard deviation indicates that Eye Remember Enterprises has less variability in its closing prices than The Azure Travel Company.
Step-by-step explanation:
The result shows that the greater the standard deviation of the stock price of the Azure Travel Company than that of Eye Remember Enterprises, the greater the variance between each stock's price and their mean closing prices. This implies a larger price range in the stock of the Azure Travel Company than it is the case with the Eye Remember Enterprises. It is noteworthy that a volatile stock has a high standard deviation, while the standard deviation of a stable blue chip stock is usually rather low.

A lemonade seller calculates that it costs $ to produce glass of lemonade and $ to produce glass of lemonade. Assume the relationship between the cost and the number of glass of lemonade produced is linear. What is the most reasonable estimate for producing glass of lemonade
Question:
A lemonade seller calculates that it costs $50 to produce 52 glass of lemonade and $110 to produce 127 glass of lemonade. Assume the relationship between the cost and the number of glass of lemonade produced is linear. What is the most reasonable estimate for producing 193 glass of lemonade?
Answer:
[tex](a).\ y = 0.8x + 8.4[/tex]
[tex](b).\ Estimate = \$163[/tex]
Step-by-step explanation:
Represent number of lemonade with x and the cost with y.
So:
[tex](x_1,y_1) = (52,50)[/tex]
[tex](x_2,y_2) = (127,110)[/tex]
Solving (a): The linear relationship between them.
First, calculate slope (m)
m = ∆y ÷ ∆x
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{110 - 50}{127 - 52}[/tex]
[tex]m = \frac{60}{75}[/tex]
[tex]m = 0.8[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - 50 = 0.8(x - 52)[/tex]
[tex]y - 50 = 0.8x - 41.6[/tex]
Make y the subject
[tex]y = 0.8x - 41.6 + 50[/tex]
[tex]y = 0.8x + 8.4[/tex]
Solving (b): Estimate of 193 lemonade
In (a), we have:
[tex]y = 0.8x + 8.4[/tex]
Substitute 193 for x
[tex]y = 0.8 * 193 + 8.4[/tex]
[tex]y = 154.4 + 8.4[/tex]
[tex]y = 162.8[/tex]
[tex]Estimate = \$163[/tex]

Error Analysis A contractor purchases 5 dozen pairs of padded work gloves for $69.60. He
incorrectly calculates the unit price as $13.92 per pair for the expense report What is the correct unit
price? What is the error?
The correct unit price is $ per pair
Answer:
The correct unit price is $1.16 per pair.
The contractor calculated the unit price in terms of per dozen.
Step-by-step explanation:
Given that:
Cost of 5 dozen pairs = $69.60
Unit price per dozen = [tex]\frac{69.60}{5} =\$13.92[/tex]
Unit price means the price of one pair of padded work gloves, so we will convert dozens into unit.
1 dozen = 12 pairs
5 dozen = 60 pairs
Unit price = [tex]\frac{69.60}{60}[/tex]
Unit price = $1.16 per pair
Hence,
The correct unit price is $1.16 per pair.
The contractor calculated the unit price in terms of per dozen.

What is the rate of change for the linear relationship modeled in the table? (4 points)
x y
-1 10
1 9
3 8
5 7
negative one over two
0
one over two
2
Answer:
-1/2
Step-by-step explanation:
In a linear relationship, the rate of change of one variable with respect to the other is constant. When we talk about change, we're looking for a difference of values.
If we look at the first and second rows, the change in x is 1 - (-1) = 2, while the change in y is 9 - 10 = -1. Usually we refer to these changes as Δx and Δy (read like "delta-x" and "delta-y"), and the rate of change is the number we get by dividing one of these by the other.
The rate of change we're used to seeing, sometimes called the slope, is Δy/Δx. So, using the values we've already found:
[tex]\Delta{x}=2\\\Delta{y}=-1\\\Delta{y}/\Delta{x}=-1/2[/tex]

Make the following statement an equations (3,-3) m=3
Answer:
We conclude that the line of equation containing the point (3, -3) with the slope m =3 will be:
[tex]y=3x-12[/tex]The graph of the line is also attached.
Step-by-step explanation:
Given
The point (3,-3)The slope m = 3Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line (x₁, y₁) is the pointsubstituting the values m = 3 and the point (x₁, y₁) = (3,-3)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-3\right)=3\left(x-3\right)[/tex]
Apply rule: -(-a) = a
[tex]y+3=3\left(x-3\right)[/tex]
subtract 3 from both sides
[tex]y+3-3=3\left(x-3\right)-3[/tex]
simplify
[tex]y=3x-12[/tex]
Therefore, we conclude that the line of equation containing the point (3, -3) with the slope m =3 will be:
[tex]y=3x-12[/tex]The graph of the line is also attached.

The coordinates of the vertices of △XYZ are X(−5, 5), Y(−3, −2), and Z(4, 0). The slope of XZ is __, the slope of YZ is __, and the slope of XY is __. △XYZ __ a right triangle because ____________.
-7/2 -5/9 -2/7 2/7 9/5 is is not no two of these slopes have a product of -1 two of these problems have a product of -1
Answer:
Slope of XZ = -5/9
Slope of YZ = 2/7
Slope of XY = -7/2
Step-by-step explanation:
Slope is expressed as;
m = y2-y1/x2-x1
For XZ
X(−5, 5), and Z(4, 0)
Slope of XZ = 0-5/4-(-5)
Slope of XZ = -5/4+5
Slope of XZ = -5/9
For YZ
Y(−3, −2), and Z(4, 0).
Slope of YZ = 0-(-2)/4-(-3)
Slope of YZ = 2/4+3
Slope of YZ = 2/7
For XY
X(−5, 5), Y(−3, −2)
Slope of XY = -2-5/-3-(-5)
Slope of XY = -7/-3+5
Slope of XY = -7/2
For two lines to be perpendicular, the product of their slope must be -1
Taking the product of XY and YZ
mXY * mYZ = -7/2 * 2/7
mXY * mYZ = -1
since the product of mXY and mYZ is -1. this shows that line XY is perpendicular to YZ and showing that the triangle XYZ is right triangle
1 Imagine you throw three hoops over these cones
Add together the number of each
cone you get a hoop on.
You have three throws a turn.
What different totals can you
make on each turn?
30
90
40
Answer:
10 different total we can make.
Step-by-step explanation:
Consider the provided information.
It is given that we have three hoops and three cones of numbers 30, 40 and 90.
We are assuming that if we throw a hoop, it always falls on a cone.
Then the different totals are shown below:
If all three hoops fall on the same cone.
1) 30+30+30=90
2) 40+40+40=120
3) 90+90+90=270
If two out of three hoops fall on the same cone.
4) 30+40+40=110
5) 30+90+90=210
6) 40+30+30=100
7) 40+90+90=220
8) 90+30+30=150
9) 90+40+40=170
If all the hoops fall on the different cone.
10) 30+40+90=160
Hence, 10 different total we can make.
