Answer:
9.71 ÷ 9.82 = .9987 or 1% .
The percentage increase is 1.1% to the nearest tenth
The calculation can be done as follows
Original price= $9.82
increase= $9.71
Change in price= 9.82-9.71
= 0.11
percent increase= 0.11/9.82 × 100
= 1.12
= 1.1 (to the nearest tenth)
Hence the percent increase is 1.1%

He fed his dog one-half of a pound of dog food
each day. Which equation is used to determine,
y, the amount of dog food that remains at the
end of each day, x?
The answer choices are on the top. Also please don’t send me links :) <3
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]

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.
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%.
Answer:
0.296
Step-by-step explanation:

With individual lines at its various windows, a post office finds that the standard deviation for normally distributed waiting times for customers on Friday afternoon is 7.2 minutes. To test this claim, the post office experiments with a single, main waiting line and finds that for a random sample of 25 customers, the waiting times for customers have a standard deviation of 3.5 minutes. a) With a significance level of 5 percent, conduct an appropriate test on the claim. (State your null hypothesis, test statistic, critical value, decision rule, conclusion) (15 points) b) What is the 95% confidence interval for the population variance
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.

O A. (7)
(2.2)
B. (5,7)
10
O C. (5.3)
O D. (7/ 2 )
SUBMI
Answer:
(2.5 , 3.5)
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)6 times the number of waiters at a restaurant was 6 less than the number of

Morgan bought a sofa for $216.00. The finance charge was $25 and she paid for it over 15 months.
Use the formula Approximate APR =(Finance Charge÷#Months)(12)Amount Financed
to calculate her approximate APR.
Round the answer to the nearest tenth.
9.4%
9.3%
1.2%
1.1%
Answer:
9.3%
Step-by-step explanation:
Morgan's approximate APR is approximately 1.0%.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Using the given formula:
Approximate APR = (Finance Charge ÷ Months) x 12 / Amount Financed
We know that the amount financed is the total cost of the sofa minus the finance charge, which is:
Amount Financed = $216.00 - $25.00 = $191.00
We also know that the finance charge was $25.00 and she paid for it over 15 months, so:
Finance Charge ÷ Months
= $25.00 ÷ 15
= $1.67
The approximate APR is:
Approximate APR = ($1.67 x 12) ÷ $191.00 = 0.1393
Rounding this to the nearest tenth gives us 0.1, which is equivalent to 1.0% as the nearest percentage.
Therefore,
Morgan's approximate APR is approximately 1.0%.

If 2 inches on a map represents 25 miles, how many inches would represent 225 miles?
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.

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.
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

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.
