What is the equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here given that,

Oliver is buying equipment for his restaurant. He can buy two blenders for $\(396\) or three blenders for $\(479\).

So,

Oliver buying two blenders at  $\(396\) so the cost of one blender is

i.e., \(\frac{396}{2}=198\)$

Oliver buying two blenders at  $\(479\)  so the cost of three blenders is

Starting with the least likely event, the chances of a politician fulfilling all his or her campaign promises can be quite low due to the complexities of politics and the potential for unforeseen circumstances.

Next, while full moons are relatively common, they occur approximately once a month, making it more likely than the politician's scenario but less likely than the other events.

Rolling a die and getting a 6 has a higher likelihood as there is a 1 in 6 chance of rolling a 6 on a fair six-sided die. The safe arrival of a person in New York City from Chicago is more probable than the previous events but still has an element of uncertainty regarding the fate of their luggage.

Randomly selecting an ace from a regular deck of 52 playing cards has a higher probability compared to the previous events, as there are four aces in a deck. The likelihood increases further when randomly selecting the queen of hearts, which is only one specific card out of the 52-card deck.

The optimal solution for the amount of cash to withdraw each time to minimize transportation costs and maximize interest earnings is determined by calculating the Economic Order Quantity (EOQ) using the formula Q = √((2 * C * T) / r), and rounding the result to a convenient amount.

The Economic Order Quantity (EOQ) model is typically used for inventory management, not for optimizing cash withdrawals. However, if we assume that the question is seeking an optimal withdrawal strategy to minimize transportation costs and maximize interest earnings, we can approach it as follows:

Let's denote:

C = Annual cash need ($5,000)

T = Transportation cost per visit ($5)

r = Annual interest rate (5%)

To find the optimal solution for the amount of cash to withdraw each time, we can consider the trade-off between transportation costs and interest earnings. The objective is to minimize the total cost.

Calculate the optimal order quantity (Q) using the EOQ formula:

Q = √((2 * C * T) / r)

Round the calculated Q to the nearest convenient amount, such as multiples of $100 or $500.

The optimal solution would be to withdraw the rounded Q amount each time to minimize transportation costs while still meeting the annual cash need.

All three scenarios, the percentage of working phones is 100%. This means that all the phones considered (50, 100, and 500) are working properly.

To determine the percentage of working phones, we need to compare the number of working phones to the total number of phones being considered. Let's calculate the percentages for different scenarios:

The next 50 phones are working:

In this case, we have 50 working phones out of 50 phones total.

Percentage of working phones = (Number of working phones / Total number of phones) * 100

Percentage of working phones = (50 / 50) * 100 = 100%

The next 100 phones are working:

In this case, we have 100 working phones out of 100 phones total.

Percentage of working phones = (Number of working phones / Total number of phones) * 100

Percentage of working phones = (100 / 100) * 100 = 100%

The next 500 phones are working:

In this case, we have 500 working phones out of 500 phones total.

Percentage of working phones = (Number of working phones / Total number of phones) * 100

Percentage of working phones = (500 / 500) * 100 = 100%

In all three scenarios, the percentage of working phones is 100%. This means that all the phones considered (50, 100, and 500) are working properly.

It's important to note that these calculations assume that there are no defective or non-working phones in the given batches. If there were any non-working phones, the percentages would be different, and the calculation would depend on the specific number of non-working phones in each batch.

The equation in slope-intercept form of the parallel line is y = -1/2x + 13

From the question, we have the following parameters that can be used in our computation:

Point = (10, 8)

Graph, \(2(y-4)+\frac{3 x+4}{3}=-5\)

Make y the subject in the equation and simplify

\(2(y-4) = - \frac{3 x+4}{3} -5\)

\(2y-8 = - \frac{3 x+4}{3} -5\)

\(2y = - \frac{3 x+4}{3} +3\)

\(2y = - \frac{3 x-5}{3}\)

\(y = - \frac{3 x-5}{6}\)

The lines are parallel

So, they have the same slope of -3/6

The equation is then calculated as

y = m(x - X) + Y

Where

(X, Y) = (10, 8)

m = slope = -3/6 = -1/2

So, we have

y = -1/2(x - 10) + 8

When expanded, we have

y = -1/2x + 13

Hence, the equation is y = -1/2x + 13

x = 16

m∠Y = 34°

Triangle XYZ is an isosceles triangle so, the angles ∠X and ∠Y are equal in measurement.

We can write the following equation to find the value of x:

4x + 9 = 73

Subtract 9 from both sides.

4x = 64

Divide both sides with 4.

x = 16

The sum of interior angles in a triangle is equal to 180°.

m∠X + m∠Y + m∠Z = 180°

73 + 73 + m∠Y = 180°

146 + m∠Y = 180°

m∠Y = 34°

SS₁ is approximately 78. To calculate SS₁ , we can use the formula:

SS₁ = (n1 - 1) * s1²

where s1 is the sample standard deviation for sample 1.

We are given n₁= 11, df₁ = 10, df₂= 20, s₁ = 5.4, and SS₂ = 12482. To find SS1, we first need to find the sum of squares for the total (SST), which is:

SST = (n₁+ n₂ - 1) * s²

where s is the pooled standard deviation. To find s, we can use the formula:

s = sqrt (SS₁ + SS₂) / (df₁ + df₂)

We are given SS₂and df₁ df₂, so we can solve for s:

s = sqrt (SS₁ + 12482) / (10 + 20) = sqrt (SS₁ + 12482) / 30)

To find SST, we can then use:

SST = (n₁ + n₂ - 1) * s² = (11 + 21 - 1) * [(SS₁ + 12482) / 30] = 750.9333 * (SS1 + 12482)

We know that SST = SS₁+ SS₂, so we can solve for SS1:

SS₁ = SST - SS₂ = 750.9333 * (SS1 + 12482) - 12482

Simplifying this expression, we get:

750.9333 * SS1 = 58998.2667

Therefore, SS1 = 78.373

Rounding to the nearest whole number, we get: SS1 ≈ 78

Therefore, SS1 is approximately 78.

Arithmetic operations consists primarily of operations such as addition, subtraction, multiplication, and division. So the option A is correct.

The process of adding things together is known as addition. The '+' sign represents the addition process. It entails combining two or more numbers into a single expression.

The difference between two numbers is calculated using the subtraction operation. The '-' sign represents subtraction. It is nearly identical to addition, but it is the conjugate of the second term.

Multiplication is also referred to as repeated addition. It is indicated by " or '*'. It can also be combined with two or more values to produce a single value.

Division is the inverse of multiplication and is usually denoted by ". It is made up of two terms, dividend and divisor, and the dividend is divided by the divisor to yield a single term value.

To solve this problem, we can use algebraic equations. Let's say that the number of weeks it takes for Ted and Carly to have the same account balance is "w".

Ted's account balance after "w" weeks can be represented by:

300 + 4w

Carly's account balance after "w" weeks can be represented by:

16w

We want to find out when their account balances will be equal, so we can set these two equations equal to each other:

300 + 4w = 16w

Simplifying this equation, we get:

300 = 12w

Dividing both sides by 12, we get:

25 = w

Therefore, it will take 25 weeks for Ted and Carly to have the same account balance.
