Answer:
b = 5
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2 + b^2 = 13^2
144+b^2 =169
Subtract 144 from each side
144-144+b^2 = 169-144
b^2 = 25
Take the square root on each side
sqrt(b^2) = sqrt(25)
b = 5
Answer:
B= 5

How wide should the door be on the scale drawing?
cm
Explain how you know
Type your response in the box below.
c. Mai's kitchen table measures 4 cm by 2.5 cm on the scale drawing.
What are the actual measurements of her kitchen table?
Type your answers in the boxes below.
Answer:
Her door should be 3cm on scale
The actual dimension of the kitchen table is
\(Length = 1.6m\)
\(Width = 1m\)
Step-by-step explanation:
Given
\(Scale= 1 : 40\)
\(Kitchen\ Dimension= 6m\ by\ 2m\)
\(Door\ Width = 1.2m\)
Solving (a): The width of the door on the scale
Represent the scale width with x
So, we have:
\(1 : 40\)
and
\(x : 1.2\)
Equate both ratios
\(1 : 40 = x : 1.2\)
Represent as fraction
\(\frac{1}{40} = \frac{x}{1.2}\)
Solve for x
\(x = \frac{1.2}{40}\)
\(x = 0.03m\)
\(x = 3cm\)
Hence, her door should be 3cm on scale
Solving (b): Actual Dimension of the kitchen table
To solve this, we simply multiply the scale dimensions by 40
\(Length = 4cm * 40\)
\(Length = 160cm\)
\(Length = 1.6m\)
\(Width = 2.5cm * 40\)
\(Width = 100cm\)
\(Width = 1m\)
Hence:
The actual dimension is
\(Length = 1.6m\)
\(Width = 1m\)

Miss Franklin is getting married soon. She would like to hire a professional who will come to her house and do hair and makeup for the bridal party on her wedding day. She has narrowed it down to two possible choices. A woman from Princeton Salon charges an initial fee of $50 and then an additional $25 per hour. Alternatively, a team from Beauty by Angie offers a free consultation and then charges a higher hourly rate of $30. If it takes a certain amount of time to finish everyone's hair and makeup, Miss Franklin will end up paying the same amount either way. How much would Miss Franklin end up paying?
Answer:
10 hours
Step-by-step explanation:
Let A be the Princeton Salon and B is Beauty by Angle.
Build a table that contains the information. See attached.
The cost, y, for x hours, for each option would be:
A: y(A) = 50 + 25x
B: y(B) = 0 + 30x
We want to find the hours, x, for which both options, so set them equal to each other:
50 + 25x = 0 + 30x
-5x = 150
x = 10 hours
The table confirms this calculation.

The NWBC found that 67.6% of women-owned businesses provided employees health insurance. What sample size could be 90% confident that the estimated (sample) proportion is within 3 percentage points of the true population proportion?
If we take a random sample of 603 women-owned businesses, we can be 90% confident that the estimated proportion of businesses providing health insurance will be within 3 percentage points of the true population proportion.
To determine the sample size needed to estimate a population proportion with a specified margin of error, we can use the formula:
n = (\(z^2\) * p * (1-p)) /\(E^2\)
where:
n = sample size
z = z-score for the desired confidence level (1.645 for 90% confidence)
p = estimated population proportion (0.676 in this case)
E = margin of error (0.03 or 3 percentage points)
Substituting the given values, we get:
\(n = (1.645^2 * 0.676 * (1-0.676)) / 0.03^2\)
n = 602.36
Rounding up to the nearest integer, we get a required sample size of 603. Therefore, if we take a random sample of 603 women-owned businesses, we can be 90% confident that the estimated proportion of businesses providing health insurance will be within 3 percentage points of the true population proportion.

Brozony musical was attended by a total of 2233 people, including men, women and children. The number of women who atended the event
was more than 3 times the number of children while the number of men was less than 4 mes the number of women. Wirite an ecuation to
model this station. Then use the ention to find the number of men, women and children who attended the musical
Answer:
Let x represents the number of children in the Broadway musical,
Since, The number of women who attended the event was 5 more than 3 times the number of children,
⇒ The number of women = 3x + 5
Also, the number of men was 3 less than 4 times the number of women,
⇒ The number of men = 4(3x+5)-3 = 12x + 20 - 3 = 12x + 17
Thus, the total number of persons = x + 3x + 5 + 12x + 17 = 16x + 22
According to the question,
16x + 22 = 2838
Which is the required equation,
Subtract 22 on both sides,
16x = 2816 ⇒ x = 176
Hence, the total number of children = 176
The number of women = 3 × 176 + 5 = 533
And, the number of men = 12 × 176 + 17 = 2129

a town's population has been growing linearly. in 2003, the population was 59000, and the population has been growing by 1700 people each year. write an equation for the population x years after 2003.
Answer:
The population after x years will be P = 29000 + 700x
Let the population after the years be represented by P
Population of the town in 2003 = 29000
Annual increase in growth = 700
Then, the population after x years will be:
P = 29000 + 700(x)
P = 29000 + 700x
Therefore, the population will be P = 29000 + 700x.
If the probability of a new employee in a fast-food chain still being with the company at the end of the year is 0. 5, what is the probability that out of 8 newly hired people?
Using binomial distribution, the probability of
a. 5 will still be with the company after 1 year is 28%.
b. at most 6 will still be with the company after 1 year is 89%.
The probability of a new employee in a fast-food chain still being with the company at the end of the year is given to be 0.6, which can be taken as the success of the experiment, p.
We are finding probability for people, thus, our sample size, n = 8.
Thus, we can show the given experiment a binomial distribution, with n = 8, and p = 0.6.
(i) We are asked for the probability that 5 will still be with the company.
Thus, we take x = 5.
P(X = 5) = (8C5)(0.6⁵)((1 - 0.6)⁸⁻⁵),
or, P(X = 5) = (56)(0.07776)(0.064),
or, P(X = 5) = 0.27869184 ≈ 0.28 or 28%.
(ii) We are asked for the probability that at most 6 will still be with the company.
Thus, our x = 6, and we need to take all values below it also.
P(X ≤ 6)
= 1 - P(X > 6)
= 1 - P(X = 7) - P(X = 8)
= 1 - (8C7)(0.6)⁷((1 - 0.6)⁸⁻⁷) - (8C8)(0.6)⁸((1 - 0.6)⁸⁻⁸)
= 1 - 8*0.0279936*0.4 - 1*0.01679616*1

You estimate that you will owe $62,100 in student loans by the time you graduate. The interest rate is 4.6 percent. If you want to have this debt paid in full within 25 years, how much must you pay each month? Monthly payment =$ Allowed attempts: 3 Now suppose you decide to defer your payments for 2 years. What will the balance of your loans be when you start to make payments? (Hint interest will still be charged monthly). New balance =$ Allowed attempts: 3 At this point, how much will you need to pay each month to pay the debt in full over 25 years? New payment =$ Alowed attempts:3 Suppose you want to make up for lost time and pay off your debts within 25 years from graduation, despite the deforral. What monthly payment is required to meat this goal? Monthly payment =$
Monthly payment before deferral: $345.09. Balance after deferral: $67,901.53. Monthly payment after deferral: $380.57. Monthly payment to pay off debt within 25 years from graduation: $421.63.
To calculate the monthly payment for a student loan, we can use the loan amortization formula.
Monthly payment calculation:
We can use the formula for calculating the monthly payment on an amortizing loan:
PMT = (P * r) / (1 - (1 + r)^(-n))
where PMT is the monthly payment, P is the loan amount, r is the monthly interest rate, and n is the total number of payments.
Given:
P = $62,100 (loan amount)
r = 4.6% per year / 12 months = 0.046/12 (monthly interest rate)
n = 25 years * 12 months = 300 (total number of payments)
Substituting these values into the formula, we can calculate the monthly payment:
PMT = (62,100 * (0.046/12)) / (1 - (1 + (0.046/12))^(-300))
Balance after deferral period:
To calculate the balance after the deferral period of 2 years, we need to calculate the interest accrued during that period and add it to the original loan amount:
Interest accrued during deferral = P * r * deferral period (in years)
New balance = P + Interest accrued during deferral
New monthly payment after deferral period:
To calculate the new monthly payment after the deferral period, we can use the same formula as before, but with the new balance and the remaining number of payments:
New PMT = (New balance * r) / (1 - (1 + r)^(-n))
Monthly payment to pay off the debt within 25 years from graduation:
To calculate the monthly payment to pay off the debt within 25 years from graduation, we need to adjust the remaining number of payments:
Remaining number of payments = 25 years * 12 months - deferral period
Then we can use the same formula as before to calculate the monthly payment.
