Find the APR, rounded to the nearest tenth of a percent (one decimal place) for the loan. Purchase a living room set for $4,900 at 8% add-on interest for 4 years. Enter only the number without % sign.
The annual percent rate(APR) to purchase a living room set for $4,900 at 8% add-on interest for 4 years is 8. 6
How to calculate the annual interest rate
Using the formula
APR = ((Interest + Fees / Loan amount) / Number of days in loan term)) x 365 x 100
Note that Interest expense = Original amount / interest rate
Interest amount = $4, 900
Rate = 8% = 0. 08
Interest expense = $4, 900× 0. 08 = $392
Loan amount is also the principal amount , P = I / (RT)
where I is Interest Amount, R is Rate of Interest and T is Time Period.
Principal amount = $4, 900 ÷ 0. 08 × 4 = $4, 900 ÷ 0.32 = $ 15,313. 5
Substitute the values into the formula for APR
APR = [tex]\frac{392+ 4900}{15312.5} / 1460 * 365* 100[/tex]
APR = [tex]0.345 / 1460 *365*100[/tex]
APR = [tex]2. 36* 10^-4 *365* 100[/tex]
APR = [tex]8. 625[/tex]
To the nearest tenth is, 8. 6
Therefore, the annual percent rate(APR) is 8. 6

The simple interest rate is 8% if the Jackie decided to open a restaurant. She borrowed 25000 for 5 years. After 5 years, she had paid back 35000.
What is simple interest?It is defined as the interest on the based on the principal amount, it does not include the compounded amount. The interest calculate on the initial amount or borrowed amount.
We have:
Jackie decided to open a restaurant. She borrowed 25000 for 5 years. After 5 years, she had paid back 35000.
We know the formula for simple interest is:
A = p(1 + rt)
We have A(final amount) = 35000
P(initial amount0 = 25000
t(time) = 5 years
35000 = 25000(1 + 5r)
1.4 = 1 + 5r
0.4 = 5r
r = 0.08 or

maxine earns $1250 dollars a month. whats is the maximum amount she should use for budget for housing?
show your work so I know how to do this
Answer:
The National Housing Act of 1937 established guidelines for maximum rents for low-income families. Originally the maximum rent threshold was set at 20%, however this increased to 30% in 1981 (and has remained at this level ever since). This figure is used to determine how much of your gross monthly income you should spend on rent.
The 28% Rule is used for determining how much of your gross monthly income should be used for a mortgage, however the FHA's threshold is a little higher at 31% of your gross monthly income on a mortgage.
Renting:
30% of $1,250 = 0.3 × 1250 = $375
Mortgage 28% Rule:
28% of $1,250 = 0.28 × 1250 = $350
Mortgage 31% FHA:
31% of $1,250 = 0.31 × 1250 = $387.50
Therefore, discounting the higher FHA's threshold, the maximum amount to budget for housing is:
$375 (if renting)$350 (if buying)Solve √x-1= x-3. Check for extraneous solutions.
A.No solution
B.x=2,5
C.x=5
D.x=2
Answer is C x=5
Step-by-step explanation:
so, "- 1" is also part of the square root ?
sqrt(x - 1) = x - 3
it is clear that for any value x < 1 we have no solution in R (as this makes the argument of the square root negative, and there is so real number solution for the square root of negative numbers).
now square the whole equation.
x - 1 = (x - 3)² = x² - 6x + 9
x² - 7x + 10 = 0
the general solution for quadratic equations is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = -7
c = 10
x = (7 ± sqrt(49 - 4×1×10))/(2×1) =
= (7 ± sqrt(49 - 40))/2 = (7 ± sqrt(9))/2
x1 = (7 + 3)/2 = 10/2 = 5
x2 = (7 - 3)/2 = 4/2 = 2
x2 is probably (given the answer options) not a valid solution for the original problem, as it represents the negative solution of sqrt(x - 1).
sqrt(2 - 1) = 2 - 3
± 1 = -1
remember, every square root has always 2 solutions : a positive and a negative one.
your teacher clearly only wanted the positive solution, which is x1 = 5.
so, yes,
C. x = 5
is the correct answer.
but please send your teacher my regards and comments. he/she has to state that only the positive solution to the square root is required/allowed.
because, formally, also x = 2 is a valid solution.
and therefore, C. AND D. are correct answers !!!!

A shipment of 50,000 transistors arrives at a manufacturing plant. The quality control engineer at the plant obtains a random sample of 500 resistors and will reject the entire shipment if 10 or more of the resistors are defective. Suppose that 4% of the resistors in the whole shipment are defective. What is the probability the engineer accepts the shipment? Do you believe the acceptance policy of the engineer is sound?
Step-by-step explanation:
remember, the number of possible combinations to pick m out of n elements is C(n, m) = n!/(m! × (n-m)!)
50,000 transistors.
4% are defective, that means 4/100 = 1/25 of the whole.
so, the probability for one picked transistor to be defective is 1/25.
and the probability for it to work properly is then 1-1/25 = 24/25.
now, 500 picks are done.
to accept the shipment, 9 or less of these 500 picks must be defective.
the probability is then the sum of the probabilities to get
0 defective = (24/25)⁵⁰⁰
1 defective = (24/25)⁴⁹⁹×1/25 × C(500, 1)
= 24⁴⁹⁹/25⁵⁰⁰ × 500
2 defective = (24/25)⁴⁹⁸×1/25² × C(500, 2)
= 24⁴⁹⁸/25⁵⁰⁰ × 250×499
3 defective = 24⁴⁹⁷/25⁵⁰⁰ × C(500, 3) =
= 24⁴⁹⁷/25⁵⁰⁰ × 250×499×166
...
9 defective = 24⁴⁹¹/25⁵⁰⁰ × C(500, 9) =
= 24⁴⁹¹/25⁵⁰⁰ × 500×499×498×497×496×495×494×493×492×491 /
9×8×7×6×5×4×3×2 =
= 24⁴⁹¹/25⁵⁰⁰ × 50×499×166×71×31×55×494×493×41×491
best to use Excel or another form of spreadsheet to calculate all this and add it all up :
the probability that the engineer will accept the shipment is
0.004376634...
which makes sense, when you think about it, because 10 defect units in the 500 is only 2%. and since the whole shipment contains 4% defect units, it is highly unlikely that the random sample of 500 will pick so overwhelmingly the good pieces.
is the acceptance policy good ?
that completely depends on the circumstances.
what was the requirement about max. faulty rate in the first place ? if it was 2%, then the engineer's approach is basically sound.
it then further depends what are the costs resulting from a faulty unit ? that depends again on when the defect is usually found (still in manufacturing, or already out there at the customer site, or somewhere in between) and how critical the product containing such transistors is. e.g. recalls for products are extremely costly, while simply sorting the bad transistors out during the manufacturing process can be rather cheap. if there is a reliable and quick process to do so.
so, depending on repair, outage and even penalty costs it might be even advisable to have a harder limit during the sample test.
in other words - it depends on experience and the found distribution/probability curve, standard deviation, costs involved and other factors to define the best criteria for the sample test.

b) A trader bought ar bags of rice at a cost, c= 24x+103 and sold them at a price.

Find the expression for the profit.
(i) If 20 bags of rice were sold, calculate the percentage profit.
The expression for the profit is -x^2/30 + 9x - 103 and the percentage profit on 20 bags of rice is 11.1%
How to determine the profit expression?The cost and the selling price are given as:
C(x) = 24x + 103
S(x) = 33x - x^2/30
The profit is calculated using:
P(x) = S(x) - C(x)
This gives
P(x) = 33x - x^2/30 - 24x - 103
Evaluate the like terms
P(x) = -x^2/30 + 9x - 103
Hence, the expression for the profit is -x^2/30 + 9x - 103
The percentage profitWhen x = 20, we have:
Cost: C(20) = 24 * 20 + 103 = 583
Profit: P(20) = -(20)^2/30 + 9(20) - 103 = 64.67
The percentage profit is then calculated as:
Percentage = P(x)/C(x) * 100%
This gives
Percentage = 64.67/583 * 100%
Evaluate
Percentage = 11.1%
Hence, the percentage profit on 20 bags of rice is 11.1%

[tex]\implies \boxed{r=6.0\: \sf cm\:(nearest\:tenth)}[/tex]
Question 15Given:
Area = 49 m²[tex]\theta[/tex] = 68°Substitute the given values into the formula and solve for r²:
[tex]\implies 49=\left(\dfrac{68^{\circ}}{360^{\circ}}\right) \pi r^2[/tex]
[tex]\implies \dfrac{49 \cdot 360}{68 \pi}= r^2[/tex]
[tex]\implies r^2=\dfrac{4410}{17 \pi}[/tex]
[tex]\textsf{Area of a circle} = \pi r^2[/tex]
[tex]\implies \textsf{Area of a circle N} =\dfrac{4410}{17 \pi} \cdot \pi[/tex]
[tex]\implies \textsf{Area of a circle N} =\dfrac{4410}{17}[/tex]
[tex]\implies \boxed{\textsf{Area of a circle N} =259.4\: \sf m^2\:(nearest\:tenth)}[/tex]
