Answer:
An equilateral triangle with a length of 2
Step-by-step explanation:
A 2-by-2 square implies that the square has a length and width of 2. Since equilateral triangles have the same length for all sides, it tells you that if one side is a certain length, all the other sides must have the same length. The largest length we can fit into this square would be 2 because any larger, the sides of the triangles would not fit into the square. Under the assumption that the length needs to be a whole number, the answer would be 2.

The volumes of the right prisms are listed below:
1 / 9 ft³39 / 512 in³7 / 384 cm³1 / 12 cm³3 / 25 m³3 / 8 yd³What is the volume of the prisms?In this problem we have six cases of right prisms with rectangular bases, the volume of right prisms (V), in cubic length units, is equal to the product of the area of the base (A), in square length units, and the height (h), in length units. The equation of the volume of the right prism is shown below:
V = w · l · h (1)
Where:
w - Width of the base, in length units.l - Length of the base, in length units.h - Height of the prism, in length units.Now we proceed to calculate each volume:
Prism 1 (w = 2 / 3 ft, l = 1 / 3 ft, h = 1 / 2 ft)
V = (2 / 3 ft) · (1 / 3 ft) · (1 / 2 ft)
V = 1 / 9 ft³
Prism 2 (w = 1 / 8 in, l = 3 / 4 in, h = 13 / 16 in)
V = (1 / 8 in) · (3 / 4 in) · (13 / 16 in)
V = 39 / 512 in ³
Prism 3 (w = 7 / 8 cm, l = 1 / 4 cm, h = 1 / 12 cm)
V = (7 / 8 cm) · (1 / 4 cm) · (1 / 12 cm)
V = 7 / 384 cm³
Prism 4 (w = 1 / 7 cm, l = 7 / 8 cm, h = 2 / 3 cm)
V = (1 / 7 cm) · (7 / 8 cm) · (2 / 3 cm)
V = 1 / 12 cm³
Prism 5 (w = 9 / 10 m, l = 2 / 3 m, h = 1 / 5 m)
V = (9 / 10 m) · (2 / 3 m) · (1 / 5 m)
V = 3 / 25 m³
Prism 6 (w = 7 / 8 yd, l = 6 / 7 yd, h = 1 / 2 yd)
V = (7 / 8 yd) · (6 / 7 yd) · (1 / 2 yd)
V = 3 / 8 yd³

Camila has finally found a house she adores! The cost of the home is $210,000, which she intends to purchase on a 30-year fixed mortgage. Blinded by her adoration for the
property, she has agreed to a 5.5% interest rate. Round all answers to the nearest cent.
How much will Camila pay in interest over the lifetime of the mortgage?
The total interest on the mortgage loan is $219,249.60
What is a mortgage loan?
It is a loan taken in order to purchase a property that requires periodic repayments such as monthly repayment since most mortgages are repaid monthly.
Our first task is to determine the monthly repayment using the present value formula of an ordinary annuity because the monthly payment becomes due at the end of each month.
PV=monthly repayment*(1-(1+r)^-N/r
PV=loan amount=$210,000
monthly repayment=unknown(assume it is X)
r=monthly interest rate=5.5%/12=0.00458333333333333
N=number of monthly payments in 30 years=30*12=360
$210,000=X*(1-(1+0.00458333333333333)^-360/0.00458333333333333
$210,000=X*(1-(1.00458333333333333)^-360/0.00458333333333333
$210,000=X*(1-0.19277525234572900)/0.00458333333333333
$210,000=X*0.80722474765427100/0.00458333333333333
$210,000=X*176.12176312456800000
X=$210,000/176.12176312456800000
X=monthly payment=$1,192.36
total repayments(360 months)=$1,192.36*360
total repayments(360 months)=$429,249.60

What is the equation of g(x)?
Og(x) = 5x-9
Og(x) = 5x-10
Og(x) = 5-9
Og(x) = 5-10
g(x) is just a translation of 10 units downwards, this means that the equation for g(x) is:
[tex]g(x) = f(x) - 10 = 5^x - 10[/tex]
Which is the equation of the translation?Here we know that:
[tex]f(x) = 5^x[/tex]
And we want to find the equation for g(x), which is a translation of f(x).
If you look at the graph of f(x), you can see that it passes through:
(0, 1), (1, 5), (2, 25), etc.
And the graph of g(x) passes through:
(0, -9), (1, -5), (2, 15)
So in each point, the y-component is 10 units smaller than the correspondent for f(x).
Then g(x) is just a translation of 10 units downwards, this means that the equation for g(x) is:
[tex]g(x) = f(x) - 10 = 5^x - 10[/tex]
So the correct option is the last one.

Solve the following system of equations.
{y=x−5
−x−3y=7
Write your answer as an ordered pair in the form (x,y).
Answer:
(2,-3)
Step-by-step explanation:
I am not sure if you meant the first equation to be y or -y. I solved it as y.
y = x-5 -x -3y =7
I am going to take the second equation and write it as x =
-x - 3y = 7 Give equation
-x = 3y +7 Add 3y to both sides
x = -3y-7 Multiplied each term in the equation by -1 so that x could be positive
I am going to substitute -3y-7 for x in the first equation up above
y = x - 5
y = -3y -7 - 5 Substitute -3y-7 for x
y = -3y -12 Combined -7-5
4y = -12 Added 3y to both sides
y = -3 Divided both sides by 4.
I now know that y is -3, I will plug that into x = -3y-7 to solve for x
x = -3(-3) -7
x = 9-7 A negative times a negative is a positive
x = 2

From the summary on the graphing calculator, we can conclude that the scatter plot is (c)
The sample correlation coefficientTo determine the sample correlation coefficient, we make use of the following representations:
Height is plotted on the x axisIQR is plotted on the y axisNext, we enter the values in a graphing calculator.
From the graphing calculator, we have the following summary:
X Values
∑ = 501Mean = 62.625∑(X - Mx)2 = SSx = 107.875Y Values
∑ = 834Mean = 104.25∑(Y - My)2 = SSy = 813.5X and Y Combined
N = 8∑(X - Mx)(Y - My) = -19.25R Calculation
r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))
r = -19.25 / √((107.875)(813.5))
r = -0.065
Hence, the sample correlation coefficient is -0.065
Interpret the sample correlation coefficientIn (b), we have:
r = -0.065
This means that there is a negative correlation
i.e. There does not appear to be a linear relationship between the high school girls' height and their IQ scores.
The critical correlation coefficientTo do this, we have:
Number of pairs, n = 8
Significance level =0.01
Using a graphing calculator;
At 0.01 significance level, the critical correlation coefficient is 0.7887
0.7887 is greater than 0.01

How would you describe the difference between the graphs of f(x) = 2x² and
g(x) = -2x²?
O A. g(x) is a reflection of f(x) over the line y = x.
B. g(x) is a reflection of f(x) over the line y = -1.
C. g(x) is a reflection of f(x) over the y-axis.
D. g(x) is a reflection of f(x) over the x-axis.
Answer:
D. g(x) is a reflection of f(x) over the x-axis.
Step-by-step explanation:
So when you have the equation: [tex]-2x^2[/tex] it's just negating the value of f(x), which is [tex]2x^2[/tex] and since f(x) represents the y-value, you're negating the y-value and the x-value is unchanged. So each point on f(x) was originally: (x, f(x)) and now it's (x, -f(x)). Since the y-value is changing, it's going to be reflecting across the x-axis. So g(x) is a reflection of f(x) over the x-axis.

Select the graph that best represents the inequality above.
Answer: B
Step-by-step explanation: Since x is less than 7, the graph would be all real numbers that are less than 7, so the arrow would be on the left.
Also, since x is not 7 itself (not less than or equal to), the dot cannot be a full dot. Thus, the dot must be open (or curved in some textbooks) to indicate x is not apart of 7 but less than 7.

John Daum and Chris Yin are star swimmers at a local college. They are preparing to compete at the NCAA Division II national championship meet, where they both have a good shot at earning a medal in the men’s 100-meter freestyle event. The coach feels that Chris is not as consistent as John, even though they clock about the same average time. In order to determine if the coach’s concern is valid, you clock their time in the last 9 runs and compute a standard deviation of 0.93 seconds for John and 1.08 seconds for Chris. It is fair to assume that clock time is normally distributed for both John and Chris. Let the clock time by John and Chris represent population 1 and population 2, respectively.

Party trays which cost $14 to make not including labor are sold for $35 if two people work eight hour shifts making the tray at seven dollars per hour how many trays must be sold to cover the cost including the labor?
Approximately 5 number of trays must be sold to cover all costs including labor.
How to find the work proportion?The profit on each tray that was sold excluding labor cost is;
Profit = $35-$14
Profit = $21
Total labor cost for making party tray for a day is;
Total Labor Cost = Total labor hours * wages per hour * No. of labors
Total Labor cost = $7 * $8*2
Total Labor Cost = $112

What is the value of x + y?
The value of the sum of the angles x + y of the given triangle is; 220°
How to find the angles in a triangle?We know that the sum of angles in a straight line is equal to 180°. Thus;
∠CFE + ∠OFE = 180
140 + ∠OFE = 180
∠OFE = 180 - 140
∠OFE = 40°
Similarly, we can use the same principle to get;
∠OEF + ∠BEF = 180°
∠OEF + y = 180°
∠OEF = 180 - y
Similarly,
∠AOF + ∠EOF = 180°
x + ∠EOF = 180°
∠EOF = 180 - x
Sum of angles in a triangle is equal to 180°. Thus;
40 + 180 - y + 180 - x = 180
Rearranging gives;
x + y = 180 + 180 + 40 - 180
x + y = 220°
