Answer:
y < -2x +3y > 1/2x -2Step-by-step explanation:
To find the equation of each boundary line, look for the y-intercept. Then find the rise and run to the next grid intersection to the right that is crossed by that line. The equation for the line is ...
y = mx + b . . . . . . m = rise/run = slope; b = y-intercept.
__
The lines are both dashed, so the inequalities will not include the "or equal to" case. For line (1), the shading is below the line, so the appropriate inequality symbol is <. For line (2), the shading is above the line, so the appropriate inequality symbol is >.
__
Line 1
y-intercept = +3. m = -2/1 = -2
y < -2x +3
Line 2
y-intercept = -2. m = 1/2
y > 1/2x -2

In 2002, there were 450 households in the city of Klean that recycled. Each year since 2002, the number of
households that recycle has grown by 8%. Write a function to represent the number of households
in Klean that recycle x years since 2002.
Answers
Answer:
450 x 1.08 ^ X = N
Step-by-step explanation:
Since in 2002, there were 450 households in the city of Klean that recycled, and each year since 2002, the number of households that recycle has grown by 8%, to write a function to represent the number of households in Klean that recycle X years since 2002 the following mathematical reasoning should be raised:
450 (initial number) x 1.08 (8% is added to the initial number) ^ X (years) = Number of households that recycle
450 x 1.08 ^ X = N
Thus, for example, if said number were calculated in 2007, that is, 5 years after 2002, the equation would apply as follows:
450 x 1.08 ^ 5 = N
450 x 1.4693 = N
661.20 = N

If 2 inches on a map represents 25 miles, how many inches would represent 225 miles?
Answers
Answer:18
Step-by-step explanation:
18 inches represent 225 miles.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p: q : : r : s.
This is same as p : q = r : s or p/q = r/s
Given that,
2 inches on a map represents 25 miles.
We have to calculate the value of inches that correspond to 225 miles.
Let x be the unknown value of inches that correspond to 225 miles.
Using proportional concept,
2 : 25 = x : 225
This can also be written as,
2 / 25 = x / 225
Cross multiplying,
2 × 225 = 25 x
x = (2 × 225) / 25
x = 18
Hence the value of the unknown inch is 18 inches.

Answers
9514 1404 393
Answer:
8√2 units
Step-by-step explanation:
The distance formula is useful.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((10 -2)² +(5 -13)²) = √(64 +64)
d = 8√2
The length of AB is 8√2 units.
The following table represents the highest educational attainment of all adult residents in a certain town. If a resident who is 30-49 years old is chosen at random, what is the probability that they have completed a bachelor's degree and no more? Round your answer to the nearest thousandth.
Answers
Answer:
If a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.
Step-by-step explanation:
Taking into account the educational table provided, if a resident who is 30-49 years old is chosen at random, to determine what is the probability that they have completed a bachelor's degree and no more the following calculation must be performed:
30-39 Bachelor's degree = 1576
40-49 Bachelor's degree = 443
30-39 Total = 4062
40-49 Total = 2869
4062 + 2869 = 100
1576 + 443 = X
6931 = 100
2019 = X
2019 x 100/6931 = X
201900/6931 = X
29,129 = X
Therefore, if a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.

Given the supply and demand functions below, find the demand when p = $12.
S(p) = 5p
D(p) = 120 - 4p
Answers
Answer:
S(p)=$60
D(p)=$72
Step-by-step explanation:
S(p)=5(12)
S(p)=60
D(p)=120-4(12)
D(p)=120-48
D(p)=72
From the supply and demand functions below, the demand at the given price is 72.
Given the following data:
Supply, S(p) = 5pDemand, D(p) = 120 - 4pPrice, P = $12.To determine the demand at the given price:
First of all, we would calculate the quantity of supply by substituting the value of price (P).
For supply:
[tex]S(p) = 5p\\\\S(p) = 5(12)[/tex]
S(p) = 60
For demand:
[tex]D(p) = 120 - 4p\\\\D(p) = 120 - 4(12)\\\\D(p) = 120 - 48[/tex]
D(p) = 72

(State your null hypothesis, test statistic, critical value, decision rule, conclusion) (15 points) b) What is the 95% confidence interval for the population variance
Answers
Answer:
H0 : σ²= 7.2²
H1 : σ² < 7.2
We can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.
Step-by-step explanation:
H0 : σ²= 7.2²
H1 : σ² < 7.2²
The test statistic :
X² = [(n - 1)*s² ÷ σ²]
s² = 3.5
n = sample size = 25. ; s²
X² = [(25 -1)*3.5² ÷ 7.2²
X² = (24 * 3.5^2) / 7.2^2
X² = 5.67
Pvalue from Chisquare statistic :
P(X² < 5.67) = 0.000042
Pvalue < α ; we reject the Null.
Hence, we can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.

Answers
Answer:
B
Step-by-step explanation:
so your starting value (10) is not going to have the x by it. instead he is feeding his dog so it will be subtracted from.
x is the number of days he can feed his dog. this will be mulitplied with something.
0.5 is how much he feeds his dog each day. this will be times the number of days or x.
so it makes your answer [tex]y=10-0.5x[/tex]

Step-by-step explanation:
We can use the midpoint formula . Here the points are , (2,2) and (3,5) .
• Using Midpoint Formula :-
⇒ M = { (x1 + x2)/2 , (y1 + y2)/2 }
⇒ M = ( 2+3/2 , 5+2/2 )
⇒ M = ( 5/2 , 7/2 )
⇒ M = ( 2.5 , 3.5 )
Hence the midpoint is (2.5 , 3.5)Ashley had $14.80. She spent $2.60 on lunch, then
