Step-by-step explanation:

Given the equation a = 3b, where

a = the number of shirts  Wanda has

b = the number of shirts Wanda's brother (Will) has

Hence if Wanda has 24 shirts then

24 = 3b

Divide both sides by 3

24/3 = b

b = 8 shirts

Will has 8 shirts.

Step-by-step explanation:

Phoebe has 71.8 percentage of the total cost of the swimming lessons.

A number can be expressed as a fraction of 100 using a percentage. It is often represented by the symbol "%". Percentages are commonly used to express a proportion or rate of change, particularly in business, finance, and science. For example, if a student scores 90 out of 100 on an exam, their percentage score is 90%.  

The total cost of 65 swimming lessons at £30 each is:

65 x £30 = £1950

Percentage = (Amount / Total) x 100

where "Amount" is the amount that Phoebe has, and "Total" is the total cost of the swimming lessons.

Plugging in the numbers, we get:

Percentage = (1400 / 1950) x 100

Percentage = 0.7179487 x 100

Percentage = 71.8 (rounded to 1 decimal place)

Therefore, Phoebe has 71.8% of the total cost of the swimming lessons.

The usual speed of the bus is 60 km/hr.

Speed is the rate of change in location of an item, expressed in meters per second.

Given,

Let x be the usual speed.

Speed = Distance/ Time

Time = Distance/Speed

Bus usually travels 350 miles.

It takes time for it to get there = 350/x h

The bus departs this week at 6:10, though.

The 70-minute bus delay = 70/60 = 7/6 h

The bus's current speed is (x+10) miles per hour.

The new window of time for getting there is \(\frac{350}{x+10}\)

\(\frac{350}{x}\) + \(\frac{350}{x+10}\) = \(\frac{7}{6}\)

350(\(\frac{x+10-x}{x(x+10)}\) ) = \(\frac{7}{6}\)

350 ( \(\frac{10}{x^{2} +10x}\) )= \(\frac{7}{6}\)

7(x² +10x) = 6(350)(10)

x² + 10x = 3000

x² + 10x - 3000 = 0

x² -60x + 50x - 3000 = 0

x( x - 60) + 50(x - 60) = 0

(x + 50)(x - 60) = 0

6.1). the rate of depreciation, r, is approximately 10.77%.

6.2.1). Ncominkosi's monthly installment amount was approximately R 10,505.29.

6.2.2).  Ncominkosi borrowed approximately R 377,510.83 from the bank.

6.1) Let's assume the original price of the laptop is P. According to the reducing balance method, the value of the laptop after 4 years can be calculated as P * (1 - r/100)^4. We are given that this value is 31% of the original price, so we can write the equation as P * (1 - r/100)^4 = 0.31P.

Simplifying the equation, we get (1 - r/100)^4 = 0.31. Taking the fourth root on both sides, we have 1 - r/100 = ∛0.31.

Solving for r, we find r/100 = 1 - ∛0.31. Multiplying both sides by 100, we get r = 100 - 100∛0.31.

Therefore, the rate of depreciation, r, is approximately 10.77%.

6.2.1) To determine the monthly installment amount, we can use the formula for calculating the monthly payment on a loan with compound interest. The formula is as follows:

\(P = \frac{r(PV)}{1-(1+r)^{-n}}\)

Where:

P = Monthly payment

PV = Loan principal amount

r = Monthly interest rate

n = Total number of monthly payments

Let's calculate the monthly installment amount for Ncominkosi's loan:

Loan amount = Total amount paid to the bank - Interest

Loan amount = R 596,458.10 - R 0 (No interest is deducted from the total paid amount since it is the total amount paid)

Monthly interest rate = Annual interest rate / 12

Monthly interest rate = 9.5% / 12 = 0.0079167 (rounded to 7 decimal places)

Number of monthly payments = 6 years * 12 months/year = 72 months

Using the formula mentioned above:

\(P = \frac{0.0079167(Loan Amount}{1-(1+0.0079167)^{-72}}\)

Substituting the values:

\(P = \frac{0.0079167(596458.10}{1-(1+0.0079167)^{-72}}\)

Calculating the value:

P≈R10,505.29

Therefore, Ncominkosi's monthly installment amount was approximately R 10,505.29.

6.2.2) To determine the amount of money Ncominkosi borrowed from the bank, we can subtract the interest from the total amount he paid to the bank.

Total amount paid to the bank: R 596,458.10

Since the total amount paid includes both the loan principal and the interest, and we need to find the loan principal amount, we can subtract the interest from the total amount.

Since the interest rate is compounded monthly, we can use the compound interest formula to calculate the interest:

\(A=P(1+r/n)(n*t)\)

Where:

A = Total amount paid

P = Loan principal amount

r = Annual interest rate

n = Number of compounding periods per year

t = Number of years

We can rearrange the formula to solve for the loan principal:

\(P=\frac{A}{(1+r/n)(n*t)}\)

Substituting the values:

Loan principal (P) = \(\frac{596458.10}{(1+0.095/12)(12*6)}\)

Calculating the value:

Loan principal (P) ≈ R 377,510.83

Therefore, Ncominkosi borrowed approximately R 377,510.83 from the bank.

Answer:

Nick is 6

Andrea is 18

Step-by-step explanation:

Sounds like a system of equations

Letting...

a = Andrea

n = Nick

Since she's 3 times the age, the first equation will be

a = 3n

Since in 10 years, Andrea will be 12 years older than Nick, we can write

a = n + 12

Since we have two a = ,we can set them equal to each other

3n = n + 12

Subtracting n

3n - n = 12

Now combining the n's (n is the same as 1n)

2n = 12

And last but not least, we can divide by 2

n = 6... so Nick is 6 right now.

Going back to our first equation of a = 3n, if we plug 6 in

a = 6(3) = 18.

Making Andrea 18 right now

The correct pair of constraints that needs to be added to specify that production of product 2 in period 4 and in period 5 differs by no more than 80 units is: P24 - P25 <= 80; P25-P24 <= 80. Therefore, the correct option is 5.

Here, the given information is Pij = the production of product i in period j. We need to find the pair of constraints that will specify that production of product 2 in period 4 and in period 5 differs by no more than 80 units. Thus, let the production of product 2 in period 4 and in period 5 be represented as P24 and P25 respectively.

Therefore, we can write the following inequalities:

P24 - P25 <= 80

This is because the production of product 2 in period 5 can be at most 80 units less than that of period 4. This inequality represents the difference being less than or equal to 80 units.

P25-P24 <= 80

This is because the production of product 2 in period 5 can be at most 80 units more than that of period 4. This inequality represents the difference being less than or equal to 80 units.

Therefore, we need to add the pair of constraints P24 - P25 <= 80 and P25-P24 <= 80 to specify that production of product 2 in period 4 and in period 5 differs by no more than 80 units. Hence, option 5 is the correct answer.

The given economic model has four identities, two behavioral equations, three equilibrium conditions, and four variables. The size of the labor force is 2,920,000 and the unemployment rate is 3.22%.

The identities in the model are:

Z ≡ C + I + G: This identity states that total spending (Z) is equal to consumption (C), investment (I), and government spending (G).

Yd ≡ Y - T: This identity defines disposable income (Yd) as total income (Y) minus taxes (T).

C = 100 + 0.5(Yd): This identity represents consumption (C) as a function of disposable income (Yd), with a consumption function that has an intercept of 100 and a marginal propensity to consume of 0.5.

I = 100 + 0.1Y: This identity represents investment (I) as a function of total income (Y), with an investment function that has an intercept of 100 and a marginal propensity to invest of 0.1.

The behavioral equations in the model are equations (3) and (4) above, which represent the consumption and investment functions, respectively.

The equilibrium conditions in the model are:

Y = Z: This condition states that total income (Y) is equal to total spending (Z) in the economy.

Yd = C + I: This condition ensures that disposable income (Yd) is equal to consumption (C) plus investment (I).

Y = Yd: This condition implies that total income (Y) is equal to disposable income (Yd).

The model has four variables: Z (total spending), Y (total income), Yd (disposable income), and T (taxes).

To calculate the size of the labor force and the unemployment rate, we need to know the total labor force and the number of unemployed individuals. The labor force is the sum of employed and unemployed individuals. In this case, the labor force is 2,826,000 (employed) + 94,000 (unemployed) = 2,920,000.

The unemployment rate can be calculated by dividing the number of unemployed individuals by the labor force and multiplying by 100 to get a percentage. In this case, the unemployment rate is (94,000 / 2,920,000) * 100 ≈ 3.22%.

Therefore, the size of the labor force is 2,920,000 and the unemployment rate is approximately 3.22%.

Where n is the number of trials, x is the number of successes, and p is the probability of success.

For this problem, n = 20, p = 0.88, and x is either 19 or 20.

P(19) = 20C19 * 0.88^19 * (1 - 0.88)^(20 - 19) = 0.0239
P(20) = 20C20 * 0.88^20 * (1 - 0.88)^(20 - 20) = 0.4160

For example, if you flip a coin twice, there are two possible outcomes for each flip: heads or tails. Using the fundamental counting principle, you can find the total number of outcomes by multiplying the number of outcomes for each event:2 x 2 = 4So there are four possible outcomes for flipping a coin twice: heads-heads, heads-tails, tails-heads, or tails-tails. Using the same logic, you can find the total number of outcomes for the soccer team's season record by multiplying the number of outcomes for each game:3 x 3 x 3 x ...

the control limits for the x-bar chart are 9.7439 minutes (LCL) and 11.0561 minutes (UCL), and the control limits for the R chart are 0 minutes (LCL) and 2.0529 minutes (UCL).

To compute the control limits for the x-bar (mean) and R (range) charts, we'll use the following formulas:

For the x-bar chart:

Upper Control Limit (UCL) for x-bar = x-double-bar + A2 * R-bar

Lower Control Limit (LCL) for x-bar = x-double-bar - A2 * R-bar

For the R chart:

Upper Control Limit (UCL) for R = D4 * R-bar

Lower Control Limit (LCL) for R = D3 * R-bar

Where:

x-double-bar = Overall mean of the sample means

R-bar = Overall mean of the sample ranges

A2 = Constant from the control chart constants table

D4 = Constant from the control chart constants table

D3 = Constant from the control chart constants table

For sample sizes of 4, the control chart constants are as follows:

A2 = 0.729

D4 = 2.281

D3 = 0

Given the information you provided:

Overall mean (x-double-bar) = 10.4 minutes
