Answer: $17.16
Step-by-step explanation:
To find the cost of the untaxed money, you have to divide your sales tax amount by the tax rate.
1.16÷.0725=16
Once you have your untaxed amount, you then add your sales tax to your untaxed amount,
16+1.16=17.16
When building a house, the number of days required to build varies inversely with with the number of workers. One house was built in 55 days by 15 workers. How many days would it take to build a similar house with 33 workers?
Answer: 25 days
Step-by-step explanation:
We know that it takes 55 days with 15 workers, so we need to find how many days it takes with 1 worker by taking 55 timed 15 = 825 days for 1 worker.
Then we take 825 divided by 33 and get 25 days for 33 workers.

Solve for x in this figure.
x = 111°
Interior angles of a polygon
The formula for the sum of the interior angles of a polygon with n sides is: (n-2) x 180°.
The mentioned polygon has 7 sides, so we can put this in the formula:
The sum of the interior angles = (n – 2) x 180°
= (7 – 2) x 180°
= 5 x 180°
= 900°
We already had the value of the 6 interior angles, so we can calculate the 7th angels (x) as follow:
900° = 136° + 118° + 135° + 139° + 141° + 120° + x
= 789° + x
x = 900° – 789°

In a study of helicopter usage and patient survival, among the 56,074 patients transported by helicopter, 235 of themleft the treatment center against medical advice, and the other 55,839 did not leave against medical advice. If 40 of
the subjects transported by helicopter are randomly selected without replacement, what is the probability that none
of them left the treatment center against medical advice?
The probability is
(Round to three decimal places as needed.)
The probability, which is calculated using the hypergeometric distribution, is 0.845, or 84.5%.
Given,
The answer to this question involves using the hypergeometric distribution because the patients are randomly selected from the sample without replenishment.
Hypergeometric distribution:
The probability of x successes is given by:
P(X = x) = h(x, N, n, k) = [tex]\frac{C_{k,x}*C_{N-k,n-x} }{C_{N, n} }[/tex]
The parameters are:
x is the number of successes.
N is the size of the population = 56074
n is the size of the sample = 40
k is the total number of desired outcomes = 235
The number of unique combinations of x objects from a set of n elements is provided by the following formula:
Cₙ,ₓ = n! / x! (n - x)!
The probability that none left against medical advice is P(X = 0), so:
P(X = x) = h(x, N, n, k) = [tex]\frac{C_{k,x}*C_{N-k,n-x} }{C_{N, n} }[/tex]
P(X = 0) = h(0, 56074, 40, 235) = (C₂₃₅, ₀ × C₅₆₀₇₄₋₄₀, ₄₀₋₀) / C₅₆₀₇₄, ₄₀
= (C₂₃₅, ₀ × C₅₅₈₃₉, ₄₀) / C₅₆₀₇₄, ₄₀
= 0.845
The probability is 0.845 = 84.5%.
Therefore,
The probability that none of them left the treatment center against medical advice is 0.845 = 84.5%

The wholesale price for a desk is $144 .A certain furniture store marks up the price by 20%.Find the price of the desk in the furniture store. Round the nearest cent,as necessary
The printed price of the desk on the furniture store is $173. It can be solved by the concept of cost price and selling price.
What is cost price and selling price?
Cost price is the price of the object at which it is purchaged and selling price is the price of the object at which it is sold. If cost price is more than the selling price then the seller will earn a loss. If the cost price is less than then the selling price then the seller will earn a profit.
The cost price of the furniture = $144
Now, 20% of cost price is,
[tex]=\$ 144\times\frac{20}{100}\\=\$28.8[/tex]
Now, price of furniture on the store = Cost price + 20% of cost price
= $144 + $28.8
= $172.8$
Round off the price = $173
Hence, the printed price of the desk on the furniture store is $173.

Using the equation of the proportional relationship, the number of miles she would drive on 50 gallons is: 1,660 miles.
What is a Direct Proportional Relationship?A direct proportional relationship can be defined by the equation, y = kx, where the constant of proportionality between the variables is given as the value of k.
First, we need to write an equation that defines the table of values given. To do this, find the constant of proportionality by using any pair of values from the table, say (6, 199.2):
Number of gallons used = x
Number of miles driven = y
Constant of proportionality, k = y/x = 199.2/2
k = 33.2
To write the equation for the proportional relationship, substitute k = 33.2 into y = kx:
y = 33.2x
To find the how many miles she would drive on 50 gallons, substitute x = 50 into y = 33.2x:

suppose that you have 600 feet of rope and want to use it to make a rectangle. what dimensions should you make your rectangle if you want to enclose the maximum possible area?
The dimensions of the rectangle should be 150 feet by 400 feet in order to enclose the maximum possible area.
To explain this step by step:
Step 1: We know that the perimeter of a rectangle is equal to 2*length + 2*width.
Step 2: Since we have 600 feet of rope, we can plug this number into the equation: 2*length + 2*width = 600
Step 3: To solve for the length and width, we can divide both sides by 2: length + width = 300
Step 4: We can then separate the equation into two equations: length = 300 - width and width = 300 - length
Step 5: Since we want to find the maximum possible area, we should set width equal to the larger number, 300, and set length equal to the smaller number, 300 - width.
Step 6: Plugging this into the equation, we get: width = 300 and length = 300 - width = 300 - 300 = 0.
Step 7: Therefore, the maximum possible area that can be enclosed with 600 feet of rope is 150 feet by 400 feet dimensions.

The base is 5 units and the height is 9 units.
The base is 9 units and the height is 3 units..
Answer: The base is 4 units and the height is 9 units.
Step-by-step explanation: To find the dimensions of the rectangle, we can use the coordinates of the points A, B, C, and D. The base of the rectangle is the distance between the points A and B, or the distance between the points C and D. We can find this distance by subtracting the x-coordinates of the points: 1 - (-4) = 5. Therefore, the base of the rectangle is 5 units.
Next, we can find the height of the rectangle by subtracting the y-coordinates of the points A and C, or the points B and D. We can do this by subtracting the y-coordinates of the points: 8 - (-1) = 9. Therefore, the height of the rectangle is 9 units.
Therefore, the dimensions of the rectangle are a base of 5 units and a height of 9 units, so the correct answer is A; The base is 4 units and the height is 9 units.
For the following pairs of assertions, indicate which do not
comply with our rules for setting up hypotheses and why (the
subscripts 1 and 2 differentiate between quantities for two
different populations or samples): (a) H0: μ = 100, Ha: μ > 100
These hypotheses comply with our rules. H0 cannot include equality,
so these hypotheses are not in compliance. Each μ is a statistic,
so these hypotheses do not comply with our rules. The asserted
value in H0 should not appear in Ha, so these hypotheses are not in
compliance. (b) H0: σ = 20, Ha: σ ≤ 20 These hypotheses comply with
our rules. Ha cannot include equality, so these hypotheses are not
in compliance. Each σ is a statistic, so these hypotheses do not
comply with our rules. The asserted value in H0 should not appear
in Ha, so these hypotheses are not in compliance. (c) H0: p ≠0.25,
Ha: p = 0.25 These hypotheses comply with our rules. Ha cannot
include equality, so these hypotheses are not in compliance. Each p
is a statistic, so these hypotheses do not comply with our rules.
The asserted value in H0 should not appear in Ha, so these
hypotheses are not in compliance. (d) H0: μ1 − μ2 = 25, Ha: μ1 − μ2
> 100 These hypotheses comply with our rules. H0 cannot include
equality, so these hypotheses are not in compliance. Each μ is a
statistic, so these hypotheses do not comply with our rules. The
asserted value in H0 should also appear in Ha, so these hypotheses
are not in compliance. (e) H0: S12 = S22, Ha: S12 ≠S22 These
hypotheses comply with our rules. H0 cannot include equality, so
these hypotheses are not in compliance. Each S is a statistic, so
these hypotheses do not comply with our rules. The asserted value
in H0 should not appear in Ha, so these hypotheses are not in
compliance. (f) H0: μ = 120, Ha: μ = 150 These hypotheses comply
with our rules. Ha cannot include equality, so these hypotheses are
not in compliance. Each μ is a statistic, so these hypotheses do
not comply with our rules. If μ appears in H0, then it should not
appear in Ha, so these hypotheses are not in compliance. (g) H0:
σ1/σ2 = 1, Ha: σ1/σ2 ≠1 These hypotheses comply with our rules. H0
cannot include equality, so these hypotheses are not in compliance.
Each σ is a statistic, so these hypotheses do not comply with our
rules. The asserted value in H0 should not appear in Ha, so these
hypotheses are not in compliance. (h) H0: p1 − p2 = −0.1, Ha: p1 −
p2 < −0.1 These hypotheses comply with our rules. H0 cannot
include equality, so these hypotheses are not in compliance. Each p
is a statistic, so these hypotheses do not comply with our rules.
The asserted value in H0 should not appear in Ha, so these
hypotheses are not in compliance.
