In order to be a function, you canNOT have any duplicate x's.
A) x = -2, 6, 6, 10 --> 6 is used twice so it is not a function
B) x = -2, 10, 6, 10 --> 10 is used twice so it is not a function
C) x = -2, 1, 6, 10 --> all the x's are different. This is a function!!!
D) x = -2, 1, 6, 1 --> 1 is used twice so it is not a function
Answer:
C
Step-by-step explanation:
Relationship between independent variable and dependent variable: each x corresponds to only one y, but y can each correspond to multiple x (which is why there are multiple solutions of an equation, and a solution can only launch a counter-argument )

Answers
Answer:
✔ inverses
✔ (y, x)
Step-by-step explanation:
The tables show that the two functions are inverses because the ordered pair (x, y) for one function is the ordered pair (y, x) for the other function.
How do you know if functions are inverses?Permit f be a characteristic. If any horizontal line intersects the graph of f more than as soon as, then f does now not have an inverse. If no horizontal line intersects the graph of f extra than once, then f does have an inverse.
Does every function have an inverse?No longer do all capabilities have inverses. people who do are known as "inverse." learn the way we can tell whether or not a function is inverse or now not. Inverse functions, inside the maximum preferred sense, are features that "reverse" every difference.

Answer:
Total distance covered each week is [tex]11\frac{1}{4}\ miles[/tex]
Step-by-step explanation:
Given
Days = 5 days
Distance = [tex]2\frac{1}{4}[/tex] miles
Required
Determine the total distance covered in a week
To do this, we simply multiply distance by number of days.
[tex]Total\ distance = distance * days[/tex]
[tex]Total\ distance = 2\frac{1}{4} * 5[/tex]
Convert to improper fraction
[tex]Total\ distance = \frac{9}{4} * 5[/tex]
[tex]Total\ distance = \frac{9 * 5}{4}[/tex]
[tex]Total\ distance = \frac{45}{4}[/tex]
[tex]Total\ distance = 11\frac{1}{4}[/tex]
Hence, the total distance covered each week is [tex]11\frac{1}{4}\ miles[/tex]

Ryan must read 150 pages for school tomorrow.
It took him 30 minutes to read the first 20 of
the assigned pages. At this rate, how much
additional time will it take him to finish
the reading?
Answers
Ryan has 130 pages left to read (150 − 20).
He read 20 pages in 30 minutes, which means he read at a rate of 40 pages per 1 hour.
To find out how much longer it will take him to finish the assignment, divide the total number of pages remaining (130) by the number of pages he is able to read per hour (40):
[tex]\frac{130}{40}= 3\frac{1}{4}[/tex]_________Ryan spent 30 minutes reading, so he will need 225 - 30 = 195 minutes to finish reading.
Here's the solution:
If it took Ryan 30 minutes to read 20 pages, then it will take him 30/20 = 1.5 minutes to read 1 page.
To read 150 pages, it will take him 1.5 × 150 = 225 minutes.
He already spent 30 minutes reading, so he will need 225 - 30 = 195 minutes to finish reading.
So the answer is 195

Answers
Answer:
a). Fixed cost = $800
b). The cost for 25 items is $1050
c).Range = 150
Domain g(x) = 150
Step-by-step explanation:
The cost in dollars of making x item is given by the function C(x)=10x+800.
The fixed cost is when x= 0
Fixed cost
C(0)= 10(0) +800
C(0) = 0+800
C(0)= 800
Fixed cost = $800
The cost for 25 items
C(25) = 10(25)+800
C(25) = 250+800
C(25) = 1050
The cost for 25 items is $1050
If Maximum cost=$2300
C(x)=10(x) +800= 2300
Range of x
10(x) = 2300-800
10(x) = 1500
X= 1500/10
X= 150
Range = 150

Answer:
The number of hours it takes the culture to reach 12,000 bacteria is 41 hours.
Step-by-step explanation:
To predict the number of hours it takes to culture a certain number of bacteria form a regression equation of number of hours (y) based on the number of bacteria (x) using the provided data.
The general form of the regression equation is:
[tex]y=a+bx[/tex]
Compute the values of a and b as follows:
[tex]a=\frac{\sum Y\cdot\sum X^{2}-\sum X\cdot\sum XY}{n\cdot \sum X^{2}-(\sum X)^{2}}=\frac{15\cdot 32109075 - 12565\cdot 39860}{5\cdot 32109075-(12565)^{2}}=-7.203\\\\b=\frac{n\cdot \sum XY-\sum X\cdot\sum Y}{n\cdot \sum X^{2}-(\sum X)^{2}}=\frac{5\cdot 39860- 12565\cdot 15}{5\cdot 32109075-(12565)^{2}}=0.004[/tex]
*Use the Excel data sheet attached.
The regression equation of number of hours based on the number of bacteria is:
[tex]y=-7.203+0.004x[/tex]
Compute the number of hours it takes the culture to reach 12,000 bacteria as follows:
[tex]y=-7.203+0.004x[/tex]
[tex]=-7.203+(0.004\times 12000)\\=-7.203+48\\=40.797\\\approx 41[/tex]
Thus, the number of hours it takes the culture to reach 12,000 bacteria is 41 hours.
What is the sum of the sixth terms of the geometric series 2-6+18-54+

Before we find the sum, we first find the next number.
-54×-3=162
So the whole sequence will be: 2, -6, 18, -54, 162
Find the sum
2+(-6)+18+(-54)+162

Weights and heights of turkeys tend to be correlated. For a population of turkeys at a farm, this correlation is found to be 0.64. The average weight is 17 pounds, SD is 5 pounds. The average height is 28 inches and the SD is 8 inches. Weight and height both roughly follow the normal curve. For each part below, answer the question or if not possible, indicate why not. A turkey at the farm which weighs more than 90% of all the turkeys is predicted to be taller than % of them. The average height for turkeys at the 90th percentile for weight is Of the turkeys at the 90th percentile for weight, roughly what percent would you estimate to be taller than 28 inches?
Answers
Answer:
a turkey at the farm which weighs more than 90% of all the turkeys is predicted to be taller than 79.37 % of them.
The average height for turkeys at the 90th percentile for weight is 34.554
Of the turkeys at the 90th percentile for weight, roughly the percentage that would be taller than 28 inches 79.37%
Step-by-step explanation:
The data given for the study can be listed as follows
For a population of turkeys at a farm, the correlation found between the weights and heights of turkeys is r = 0.64
[tex]\overline x[/tex] = 17 (i . e the average weight in pounds)
[tex]S_x[/tex] = 5 ( i . e the standard deviation of the weight in pounds)
[tex]\overline y[/tex] = 28 (i . e the average height in inches)
[tex]S_y[/tex] = 8 ( i . e the standard deviation of the height in inches)
The slope of the regression line can be expressed as :
[tex]\beta_1 = r \times ( \dfrac{S_y}{S_x})[/tex]
[tex]\beta_1 = 0.64 \times ( \dfrac{8}{5})[/tex]
[tex]\beta_1 = 0.64 \times 1.6[/tex]
[tex]\beta_1 = 1.024[/tex]
Similarly the intercept of the regression line can be estimated by using the formula:
[tex]\beta_o = \overline y - \beta_1 \overline x[/tex]
replacing the values, we have:
[tex]\beta_o = 28 -(1.024)(17)[/tex]
[tex]\beta_o = 28 -17.408[/tex]
[tex]\beta_o = 10.592[/tex]
However, the regression line needed for this study can be computed as:
[tex]\hat Y = \beta_o + \beta_1 X[/tex]
[tex]\hat Y = 10.592 + 1.024 X[/tex]
Recall that;
both the weight and height roughly follow the normal curve
Thus, the weight related to 90th percentile can be determined as shown below.
Using the Excel Function at 90th percentile, which can be computed as:
(=Normsinv (0.90) ; we have the desired value of 1.28
∴
[tex]\dfrac{X - \overline x}{s_x } = (Normsinv (0.90))[/tex]
[tex]\dfrac{X - \overline x}{s_x } = 1.28[/tex]
[tex]\dfrac{X - 17}{5} = 1.28[/tex]
[tex]X - 17 = 6.4[/tex]
X = 6.4 + 17
X = 23.4
The predicted height [tex]\hat Y = 10.592 + 1.024 X[/tex]
here; X = 23.4
[tex]\hat Y = 10.592 + 1.024 (23.4)[/tex]
[tex]\hat Y = 10.592 + 23.9616[/tex]
[tex]\hat Y = 34.5536[/tex]
So the probability of predicted height less than 34.5536 can be expressed as:
[tex]P(Y < 34.5536) = P( \dfrac{Y - \overline y }{S_y} < \dfrac{34.5536-28}{8})[/tex]
[tex]P(Y < 34.5536) = P(Z< \dfrac{6.5536}{8})[/tex]
[tex]P(Y < 34.5536) = P(Z< 0.8192)[/tex]
From the Z tables;
P(Y < 34.5536) =0.7937
Thus, a turkey at the farm which weighs more than 90% of all the turkeys is predicted to be taller than 79.37 % of them.
The average height for turkeys at the 90th percentile for weight is :
[tex]\hat Y = 10.592 + 1.024 X[/tex]
here; X = 23.4
[tex]\hat Y = 10.592 + 1.024 (23.4)[/tex]
[tex]\hat Y = 10.592 + 23.962[/tex]
[tex]\mathbf{\hat Y = 34.554}[/tex]
Of the turkeys at the 90th percentile for weight, roughly what percent would you estimate to be taller than 28 inches?
This implies that :
P(Y >28) = 1 - P (Y< 28)
[tex]P(Y >28) = 1 - P( Z < \dfrac{28 - 34.554}{8})[/tex]
[tex]P(Y >28) = 1 - P( Z < \dfrac{-6.554}{8})[/tex]
[tex]P(Y >28) = 1 - P( Z < -0.8193)[/tex]
From the Z tables,
[tex]P(Y >28) = 1 - 0.2063[/tex]
[tex]\mathbf{P(Y >28) = 0.7937}[/tex]
= 79.37%

Answer:
I think that it's either x= -2 or x= 0.5
Step-by-step explanation:
x=5 is the value of equation x - 3x + 4 = 3 - 9.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is x - 3x + 4 = 3 - 9
x minus three times of x plus four equal to three minus nine
In the given equation x is the variable and we need to solve the value of x.
x - 3x + 4 = 3 - 9
Add the like terms
-2x+4=-6
Subtract 4 from both sidees
-2x=-10
Divide both sides by -2
x=5
Hence, x=5 is the value of equation x - 3x + 4 = 3 - 9.
