Answer: V20
Step-by-step explanation:
Let's go down the list, shall we?
First, V64. I am going to assume that the V is a square root. If you take the square root of 64 you would get 8, which is not an irrational number.
2/2 would be one of the easiest, its just 1 if you simplify it
(16 would be a rational number, even if you took the square root.
4 is four, a rational number
V20 is an Irrational number, again, assuming that the V is a square root symbol, and you took the square root of it, you would get 4.472135955... an infinite number without a pattern
And 5 is just five, a whole number

your answwr
explain all steps in detall. Incluide your final answer.. 9²+3•(9-5)²/4=
Answer: 93
Step-by-step explanation:
To solve this problem, we need to use the order of operations, or PEMDAS.
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
For multiply/divide and add/subtract, you don't necessarily go in that specific order. You go from left to right, depending on what comes first. For example, if division comes before multiply, you would divide first, then multiply. Same goes for add/subtract.
9²+3×(9-5)²/4 [solve parenthesis]
9²+3×(4)²/4 [solve exponent]
81+3×16/4 [solve multiply or divide, whichever comes first]
81+12 [solve add or subtract, whichever comes first]
93
Now, we know that 93 is our final answer.
Each ounce of Food I contains 3 g of carbohydrate and 2 g of protein, and each ounce of Food II contains 5 g of carbohydrate and 3 g of protein. Suppose x ounces of Food I are mixed with y ounces of Food II. The foods are combined to produce a blend that contains exactly 73 g of carbohydrate and 46 g of protein.
a. Explain why there are 3x + 5y g of carbohydrate in the blend and why we must have 3x + 5y = 73. Find a similar equation for protein. Sketch the graphs of both equations.
b. Where do the two graphs in part (a) intersect? Interpret the significance of this point of intersection
Answer:
The answer is below
Step-by-step explanation:
a) Food I contains 3 g of carbohydrate and food II 5 g of carbohydrate. x is the number of ounce of food I while y is the number of ounce of food II.
Therefore, the amount of carbohydrate in food 1 is 3x while that of food II is 5y. Since the blend contains exactly 73 g of carbohydrate, the total number of carbohydrate in both food I and food II is 73 g. Hence:
3x + 5y = 73 (1)
Food I contains 2 g of protein and food II 3 g of carbohydrate. Therefore, the amount of protein in food 1 is 2x while that of food II is 3y. Since the blend contains exactly 46 g of protein, the total number of protein in both food I and food II is 46 g. Hence:
2x + 3y = 46 (2)
Using geogebra to Sketch the graphs of both equations.
b) The point of intersection is gotten from the graph, this gives x = 11, y = 8.
The point of intersection shows the amount of food I and food II that give the required amount of protein and carbohydrate.
11 ounce of food I and 8 ounce of food II would produce the required amount of protein and carbohydrate

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unknown endpoint. Apply the midpoint formula, and solve the two equations for x and y.) midpoint (1,6), endpoint (-2,1)
Answer:
(4,11)Step-by-step explanation:
Given two coordinates (x₁, y₁) and (x₂,y₂), the midpoint of the coordinates is expressed as M(X,Y) = [tex](\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex] where;
[tex]X = \dfrac{x_1+x_2}{2}\ and \ Y = \dfrac{y_1+y_2}{2}[/tex]
Given the midpoint (X, Y) = (1,6) and one end point to be (-2,1), to get the unknown endpoint (x,y), we will apply the formula above. from the coordinates given X = 1, Y = 6, x₁ = -2 and y₁ = 1
[tex]Given \ X = \dfrac{x_1+x_2}{2}\\1 = \dfrac{-2+x}{2}\\cross \ multiply\\2 = -2+x\\x = 2+2\\x = 4[/tex]
Similarly to get y;
[tex]Given \ Y = \dfrac{y_1+y}{2}\\6 = \dfrac{1+y}{2}\\cross \ multiply\\2*6 = 1+y\\12 = 1+y\\y = 12-1\\y = 11[/tex]
Hence the unknown endpoint (x,y) is (4,11)

A.
The lines are parallel.
B.
The lines are perpendicular.
The lines intersect but are not perpendicular.
C.
D.
The lines coincide.
Answer:
C. The lines intersect but are not perpendicular.
Step-by-step explanation:
The slopes (x-coefficients) of these lines are 3 and -4. They are different, but their product is not -1. Lines with different slopes are distinct lines that will intersect. If the product of their slopes is -1, they are perpendicular.
The lines intersect but are not perpendicular.
NarStor, a computer disk drive manufacturer, claims that the median time until failure for their hard drives is more than 14,400 hours. You work for a consumer group that has decided to examine this claim. Technicians ran 16 NarStor hard drives continuously for almost three years. Recently the last drive failed. The times to failure (in hours) are given in the following table. Give the test statistic.330 620 1870 2410 4620 6396 7822 81028309 12882 14419 16092 18384 20916 23812 25814
Answer:
The test statistics is [tex]t = -1.727[/tex]
Step-by-step explanation:
From the question we are told that
The data given is
330 620 1870 2410 4620 6396 7822 81028309 12882 14419 16092 18384 20916 23812 25814
The population mean is [tex]\mu = 14400[/tex]
The sample size is n = 16
The null hypothesis is [tex]\mu \le 14400[/tex]
The alternative hypothesis is [tex]H_a : \mu > 14400[/tex]
The sample mean is mathematically evaluated as
[tex]\= x = \frac{\sum x_i}{n}[/tex]
So
[tex]\= x = \frac{330+ 620+ 1870 +2410+ 4620+ 6396+ 7822+ 8102+8309+ 12882+ 14419+ 16092+ 18384 +20916+ 23812+ 25814 }{16}[/tex]
=> [tex]\= x = 10799.9[/tex]
The standard deviation is mathematically represented as
[tex]\sigma =\sqrt{\frac{ \sum (x_i - \=x)^2}{n}} [/tex]
So
[tex]\sigma =\sqrt{\frac{(330- 10799.9)^2 + (620- 10799.9)^2+ (1870- 10799.9)^2 +(2410- 10799.9)^2 + (4620- 10799.9)^2 +(6396- 10799.9)^2 +(7822- 10799.9)^2 }{16}} \ ..[/tex]
[tex]..\sqrt{ \frac{(8102 - 10799.9)^2 +(8309 - 10799.9)^2 + (12882 - 10799.9)^2 + (14419 - 10799.9)^2 + (16092 - 10799.9)^2 + (18384 - 10799.9)^2 +(20916 - 10799.9)^2 }{16}} \ ...[/tex]
[tex]\ ... \sqrt{\frac{(23812 - 10799.9)^2 +(25814 - 10799.9)^2 }{16}}[/tex]
=> [tex]\sigma = 8340[/tex]
Generally the test statistic is mathematically represented as
[tex]t = \frac{10799.9- 14400}{ \frac{8340}{\sqrt{16} } }[/tex]
[tex]t = -1.727[/tex]
From the z-table the p-value is
[tex]p-value = P(Z > t) = P(Z > -1.727) = 0.95792[/tex]
From the values obtained we see that
[tex]p-value > \alpha[/tex] so we fail to reject the null hypothesis
Which implies that the claim of the NarStor is wrong
Solve for x: −2(x + 3) = −2x − 6
Answer:
All real numbers
Step-by-step explanation:
Solution set of -2(x +3) = -2x -6 is all x ∈R (real numbers).
What is equation?
" Equation is defined as when two algebraic expression which are related with the sign of equality."
According to the question,
Given,
-2(x + 3) = -2x - 6
Open the brackets of the equation we get,
-2(x) + (-2)(3) = -2x - 6
⇒ -2x - 6 = -2x - 6
Add 6 on both the sides of the equation we get,
-2x = -2x
Divide by -2 of the equation both sides
x = x _____(1)
Add (-x) both the sides we get,
0 = 0 _____(2)
From (1) and (2) we conclude ,
Solution is true for all the real values of x.
Hence, solution set of -2(x +3) = -2x -6 is all x ∈R (real numbers).

What is the image point of
(−5,−3) after a translation right 4 units and down 1 unit?
Answer:
(-1,-4)
Step-by-step explanation:
(-5,-3) if we're moving four units right on the x axis, it would be a bigger number near the center. Think of it as adding -5 and 4, which would get you -1 for x (-1,x)
Now to get y, we would basically do the same thing except if it's going down, it would be a negative. We would add both -1 and -3 together to get -4, hence the answer, (-1,-4)

Techside Real Estate, Inc. is a research firm that tracks the cost of apartment rentals in Southwest Virginia. In mid-2002, the regional average apartment rental rate was $895 per month. Assume that, based on the historical quarterly surveys, it is reasonable to assume that the population standard deviation is $225. In a current study of apartment rental rates, a sample of 180 apartments in the region provided the apartment rental rates.
a. Do the sample data enable Techside Real Estate, Inc. to conclude that the population mean apartment rental rate now exceeds the level reported in 2002? The sample mean is $915 and the sample standard deviation is $227.50. Make your decision based on α=0.10.
b. What is the P-value?
Answer:
1) we will fail to reject the null hypothesis and conclude that the population mean apartment rental rate does not exceed the level reported in 2002
2) P - value = 0.116435
Step-by-step explanation:
We are given;
Population mean; μ = $895
Sample mean; x' = $915
Population standard deviation; σ = $225
Sample standard deviation; s = $227.50
Sample size; n = 180
Let's state the hypothesis;
Null hypothesis;H0: μ ≤ $895
Alternative hypothesis;Ha: μ > $895
Now, the z-score formula is;
z = (x' - μ)/(σ/√n)
Thus, we are making use of the population standard deviation
z = (915 - 895)/(225/√180)
z = 20/16.7705
z = 1.193
From online p-value from z-score calculator attached, with α = 0.10, one tail, we have;
The P-Value is 0.116435
This is more than the significance level of 0.1, thus we will fail to reject the null hypothesis and conclude that the population mean apartment rental rate does not exceed the level reported in 2002
The Megasoft company gives each of its employees the title of programmer (P) or project manager (M). In any given year 70% of programmers remain in that position 20% are pro- moted to project manager and 10% are fired (state X). 95% of project managers remain in that position while 5% are fired. How long on the average does a programmer work before they are fired?
Answer:
it will take a programmer about 16.67 times to work before they are fired
Step-by-step explanation:
From the information given;
The transistion matrix for this study can be computed as:
P M X
P 0.7 0.2 0.1
M 0 0.95 0.05
X 0 0 1
where;
The probability that the programmer remains a programmer = [tex](P *P)[/tex]
The probability that the programmer turns out to be a manager = [tex](P*M)[/tex]
The probability that the programmer is being fired = [tex](P*X)[/tex]
Thus, the required number of years prior to the moment being fired for an employee y(P), for programmer and y(M) for manager is represented by ;
[tex]y(P)=1+0.7y(P)+0.2y(M)[/tex]
[tex]y(M)=1+ 0.95y(M).[/tex]
[tex]0.05y(M)=1[/tex]
y(M) = [tex]\dfrac{1}{0.05}[/tex]
y(M) =20
y(P)=1+0.7y(P)+0.2y(M)
y(P) - 0.7y(P) = 1 + 0.2y(M)
0.3y(P) = 1 + 0.2(20)=1+4
0.3y(P) = 1 + 4
0.3y(P) = 5
[tex]y(P)=\dfrac{5}{0.3}[/tex]
[tex]y(P)=16.67[/tex]
Therefore, it will take a programmer about 16.67 times to work before they are fired

In the diagram,
AB =BC,AC = CD, and AD
12. Find the
lengths of all segments in the diagram. Suppose you
choose one of the segments at random. What is the
probability that the measure of the segment is greater
than 3? Explain your reasoning.
Answer:
Probability that the measure of a segment is greater than 3 = 0.6
Step-by-step explanation:
From the given attachment,
AB ≅ BC, AC ≅ CD and AD = 12
Therefore, AC ≅ CD = [tex]\frac{1}{2}(\text{AD})[/tex]
= 6 units
Since AC ≅ CD
AB + BC ≅ CD
2(AB) = 6
AB = 3 units
Now we have measurements of the segments as,
AB = BC = 3 units
AC = CD = 6 units
AD = 12 units
Total number of segments = 5
Length of segments more than 3 = 3
Probability to pick a segment measuring greater than 3,
= [tex]\frac{\text{Total number of segments measuring greater than 3}}{Total number of segments}[/tex]
= [tex]\frac{3}{5}[/tex]
= 0.6

Answer:
K(F) = 5/9 (F - 32) + 273.15
K(F)=298.15k
Step-by-step explanation:
C(F) =5/9 (F - 32) is used to convert temperature from Fahrenheit (F) to Celsius (C).
C(F) =5/9 (F - 32)
The function K(C)= C + 273.15 is used to convert temperature from Celsius (C) to the Kelvin (K) scale.
K(C)= C + 273.15
K(c) - 273= C
Equating both values of C
K(F) - 273.15=5/9 (F - 32)
K(F) = 5/9 (F - 32) + 273.15
If F = 77°F
K(F) = 5/9 (F - 32) + 273.15
K(F) = 5/9(77-32) + 273.15
K(F) = 5/9(45) +273.15
K(F) = 25+273.15
K(F)=298.15k
