Answer:
Option D
Step-by-step explanation:
Set of data in terms of ordered pairs represents a function when output value of each input value is different.
Option A
Since, for every value of x there is a different value of y, it's a function.
Option B
In each ordered pair, for every value of x there is a different value of y.
Therefore, it's a function.
Option C
From the given graph, for every value of x there is a different value of y.
Therefore, it's a function.
Option D
From the given set of ordered pairs we find for x = 1 there are two values of y (y = 4 and 3).
Therefore, the given set of ordered pairs doesn't represent a function.
Option D is the answer.
Abel Alonzo, Director of Human Resources, is exploring employee absenteeism at the Harrison Haulers Plant. Abel knows that absenteeism varies significantly between departments. For example, workers in the wood shop are absent more than those in the tuning department and the size of the departments ranges from 40 to 120 workers. He orders a random sample of 10 workers from each of the six departments. Abel's sample is a
Answer:
disproportionate stratified sample
Step-by-step explanation:
Based on the given information we can say that Abel's sample is a disproportionate stratified sample. This is the case mainly because the department worker population ranges from 40 to 120 workers. This changing population makes the 10 workers that were chosen for the sample not proportionate to the entire population. Therefore, under different population sizes workers have different chances of getting selected for the study which ultimately creates different results.

The length l of a rectangle is decreasing at a rate of 3 cm/sec while the width w is increasing at a rate of 3 cm/sec. When l=5 cm and w=12 cm, find the rates of change of the area, the perimeter, and the lengths of the diagonals of the rectangle. Determine which of these quantities are increasing, decreasing, or constant.
a) The rate of changes of the area of the rectangle is _______ cm^2/sec
Is the area increasing, decreasing, or constant?
b) The rate of change of the perimeter of the rectangle is ____ cm/sec.
Is the perimeter increasing, decreasing, or constant?
c) The rate of change of the length of the diagonals of the rectangle is ____ cm/sec.
Is the length of the diagonals increasing, decreasing, or constant.
Answer:
1) dA/dt = -21 cm²/s and Area is decreasing
2)dP/dt = 0 and perimeter is constant
3) dD/dt = 21/13 cm/s and diagonal is increasing
Step-by-step explanation:
We are given that;
length l of a rectangle is decreasing at a rate of 3 cm/sec.
Thus, dl/dt = -3 cm/sec
Also, the width w is increasing at a rate of 3 cm/sec. Thus;
dw/dt = 3 cm/sec
When l=5 cm and w=12 cm;
A) Area is given by the formula;
A = lw
The rate at which area is increasing is;
dA/dt = l(dw/dt) + w(dl/dt)
Plugging in the relevant values;
dA/dt = 5(3) + 12(-3)
dA/dt = 15 - 36
dA/dt = -21 cm²/s
This is less than 0.thus, A is decreasing.
B) Formula for perimeter is;
P = 2l + 2w
rate of change of perimeter is;
dP/dt = 2(dw/dt) + 2(dl/dt)
Plugging in the relevant values, we have;
dP/dt = 2(-3) + 2(3)
dP/dt = 0
Thus,Perimeter is constant
C) the length of the diagonal of a rectangle is given by;
D = √(w² + l²)
Rate of change of diagonal is;
dD/dt = [2w(dw/dt) + 2l(dl/dt)]/(2√(w² + l²))
2 will cancel out in numerator and denominator to give;
dD/dt = [w(dw/dt) + l(dl/dt)]/(√(w² + l²))
Plugging in the relevant values gives;
dD/dt = [12(3) + 5(-3)]/(√(12² + 5²))
dD/dt = (36 - 15)/13
dD/dt = 21/13 cm/s
This is greater than 0.
Thus, diagonal is increasing.
Write an equation of a line that is parallel to y = x - 7 and passes through the point (-6, -11).
Answer:
y = x - 5
Step-by-step explanation:
Comparing the given y = x - 7 to y = mx + b, we see that the slope is +1.
In y = x + b we replace y with -11 and x with -6 to determine the y-intercept, b:
-11 = -6 + b
Then b must be -5, and so the desired new equation is
y = x - 5

The population of Whoville is given by the LaTeX: y=56,000\left(1.03\right)^xy = 56 , 000 ( 1.03 ) xwhere x is the years since 2010.
a) What was the population in 2010?
b) What is the population in 2020?
c) When will the population reach 100,000?
Answer:
Step-by-step explanation:
(a) 56000*1.03^0 = 56000
(b) 56000*1.03^10 = 75259
(c) 56000*1.03^x = 100000
1.03^x = 1.7857
x = 19.6
So that will happen in the 2nd half of 2029
3f+2.9=4.4
Please help.
Answer:
f =0.5
Isolate the variable by dividing each side by factors that don't contain the variable.
______________________________
1.) Subtract 2.9 from both sides:[tex]2.9-2.9=[/tex] Cancels Out. [tex]4.4-2.9=1.5[/tex].- We subtract 2.9 from both sides because we need to get rid of any extra numbers on the opposite side of the equal sign. To do so, you do the opposite of what you see: We have a positive 2.9, so we subtract.
Equation at the end of Step 1:
[tex]3f=1.5[/tex].2.) Divide both sides by 3.[tex]3f[/tex] ÷ [tex]3=f[/tex].[tex]1.5[/tex] ÷ [tex]3=0.5[/tex].- We divide 3 from both sides because the 3 is attached to the variable and we need to get the variable alone. So to do so we have to divide by 3 on each side.
3.) Turn the decimal into a fraction: [tex]0.5=\frac{1}{2}[/tex].- 0.5 is equal to [tex]\frac{1}{2}[/tex] as a fraction.

A customer at a store paid $96 for 5 large candles and 7 small candles. At the same store a second customer paid $8 less than the first customer for 4 large candles and 8 smal candies Write a system that could be used find the price in dollars of each large candle, x, and each small candle, Y
Answer:
The system that could be used find the price in dollars of each large candle, x, and each small candle, Y is given as:
5x + 7y = 96...... Equation 1
4x + 8y = 88..... Equation 2
Step-by-step explanation:
From the question:
Let cost of:
large candles = x
Small candles = y
A customer at a store paid $96 for 5 large candles and 7 small candles.
Hence:
5x + 7y = 96...... Equation 1
At the same store a second customer paid $8 less than the first customer for 4 large candles and 8 smal candies
Hence:
4x + 8y = $96 - $8
4x + 8y = 88..... Equation 2
The system that could be used find the price in dollars of each large candle, x, and each small candle, Y is given as:
5x + 7y = 96...... Equation 1
4x + 8y = 88..... Equation 2
What is 2 divided by 1/7
Answer:
The answer is 14
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
Complete the multiplication and the equation becomes
The two fractions now have like denominators so you can add the numerators.

Answer:
117
Step-by-step explanation:
Hi, If you were to add 75 to 42, you would get 117. Since a triangle's angles all have to add up to 180, the last angle would be 63. However, you are looking for the outside angle, which would then just be 117. Hope this is right!
