So you use BIDMAS (Brackets, Indecies, Division, Multiplication, Addition & Subtraction)

Division comes first so you do 8÷2 first.

4+8÷2-2×4 becomes:

4+4-2×4

Next is multiplication, so you do 2 × 4

4+4-2×4 becomes:

4+4-8

Next is addition, so you do 4+4

4+4-8 becomes:

8-8

Finally its subtraction so you do 8-8

8 - 8 = 0

So your answer is B: 0 !

The quarterly operating profit margin of TMG Ltd over the past six years is provided in Table 4.1, indicating the financial performance of the business during that period.

In order to assess the impact of the intervention strategy introduced by the current CEO three years ago, the board of directors (BOD) of TMG Ltd has contracted a researcher to analyze the data and determine if there have been significant improvements in the business outcomes. The quarterly operating profit margin serves as the unit of analysis for this evaluation.

Table 4.1 allows the researcher to examine the trend and fluctuations in the quarterly operating profit margin over the six-year period. By analyzing the data, the researcher can identify any noticeable changes in the financial performance of TMG Ltd, particularly after the implementation of the intervention strategy. The BOD is interested in understanding whether the strategy has resulted in improved profitability and overall financial health of the company.

The researcher will likely perform statistical analysis, such as calculating averages, trends, and identifying any significant variations, to draw conclusions about the effectiveness of the intervention strategy. By comparing the quarterly operating profit margin before and after the strategy's implementation, the researcher can assess whether the new CEO's efforts have had a positive impact on the company's financial performance.

Answer:

y=5/3 is the only real solution

Step-by-step explanation:

Solve for y over the real numbers:

11 y^2 - 19 y - 10 = -4 y^2

Add 4 y^2 to both sides:

15 y^2 - 19 y - 10 = 0

The left hand side factors into a product with two terms:

(3 y - 5) (5 y + 2) = 0

Split into two equations:

3 y - 5 = 0 or 5 y + 2 = 0

Add 5 to both sides:

3 y = 5 or 5 y + 2 = 0

Divide both sides by 3:

y = 5/3 or 5 y + 2 = 0

Subtract 2 from both sides:

y = 5/3 or 5 y = -2

Divide both sides by 5:

Answer: |

To predict a linear regression score, you first need to train a linear regression model using a set of training data.

Once the model is trained, you can use it to make predictions on new data points. The predicted score will be based on the linear relationship between the input variables and the target variable,

A higher regression score indicates a better fit, while a lower score indicates a poorer fit.

To predict a linear regression score, follow these steps:

1. Gather your data: Collect the data p

points (x, y) for the variable you want to predict (y) based on the input variable (x).

2. Calculate the means: Find the mean of the x values (x) and the mean of the y values (y).

3. Calculate the slope (b1): Use the formula b1 = Σ[(xi - x)(yi - y)]  Σ(xi - x)^2, where xi and yi are the individual data points, and x and y are the means of x and y, respectively.

4. Calculate the intercept (b0): Use the formula b0 = y - b1 * x, where y is the mean of the y values and x is the mean of the x values.

5. Form the linear equation: The linear equation will be in the form y = b0 + b1 * x, where y is the predicted value, x is the input variable, and b0 and b1 are the intercept and slope, respectively.

6. Predict the linear regression score: Use the linear equation to predict the value of y for any given value of x by plugging in the x value into the equation. The resulting y value is your predicted linear regression score.

Answer: 35 / 66

Step-by-step explanation:

Given the data bekow:

Outcome : - - - 1 - - - 2 - - - 3 - - - 4 - - - 5 - - - 6

Frequency : - 12 - - - 9 - - - 11 - - 8 - - - 12 - - - 14

What is the experimental probability of spinning an odd

P(spinning an odd) = (number of occurrence of an event / number of trials)

Odd outcomes = 1, 3, 5

Frequency of 1 = 12

Frequency of 3 = 11

Frequency of 5 = 12

Number of occurrences of odd = (12 + 11 + 12) = 35

Number of trials = 66

Therefore,

P(spinning an odd) = 35 / 66

Considering the given tree diagram, there is a 0.5 = 50% probability of an investor choosing either stocks or bonds from portfolio C.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

At each node, the sum of the probabilities is of 1, hence:

0.2 + 0.3 + Z = 1.

Z = 0.5.

Answer:

2^6 x 3^3 and 12^3

Step-by-step explanation:

First, solve

6^3 x 2^6/2^3

216 x 64/8

13824/8 = 1728

lets solve for the answers

6^3 = 216

Therefore, 6^3 is not an answer

2^6 x 3^3= 64 x 27 = 1728

because both expressions are equal to 1728, this is an answer. this answer can also eliminate 2^3 x 3^3 because it has a lower exponent than the answer that is equal to 1728. therefore, the value of it must be smaller than 1728

12^3 = 1728

This answer is correct, because both values are equal to each other, meaning that 12^6 is larger than 1728  

Therefore, your answers will be 2^6 x 3^3 and 12^3

The given formula for the car's value after n years since it was purchased is V(n) = 28000(0.875)^n. We are asked to find the amount of value the car loses in its fifth year.

To calculate the value lost in the fifth year, we need to find the difference between the value at the start of the fifth year (V(5)) and the value at the end of the fifth year (V(4)).

Using the formula, we can calculate V(5):

V(5) = 28000(0.875)^5

To find V(4), we substitute n = 4 into the formula:

V(4) = 28000(0.875)^4

To determine the value lost in the fifth year, we subtract V(4) from V(5):

Value lost in fifth year = V(5) - V(4)

Now, let's calculate the values:

V(5) = 28000(0.875)^5

V(5) ≈ 28000(0.610)

V(4) = 28000(0.875)^4

V(4) ≈ 28000(0.676)

Value lost in fifth year = V(5) - V(4)

≈ (28000)(0.610) - (28000)(0.676)

≈ 17080 - 18928

≈ -1850

The negative value indicates a loss in value. Therefore, the car loses approximately $1,850 in its fifth year.

The upper limit of the 95% confidence interval for the population mean is approximately 77.768.

The mean of your estimate plus and minus the range of that estimate makes up a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.

To calculate the upper limit of a 95% confidence interval for the population mean, we can use the formula:

Upper Limit = Sample Mean + (Critical Value * Standard Error)

First, we need to determine the critical value for a 95% confidence interval. Since the sample size is 15 and the population is assumed to be normally distributed, we can use a t-distribution. The degrees of freedom for a sample of size 15 is 15 - 1 = 14.

Looking up the critical value for a 95% confidence level and 14 degrees of freedom in the t-distribution table, we find it to be approximately 2.145.

Next, we need to calculate the standard error, which is the standard deviation of the sample divided by the square root of the sample size:

Standard Error = Standard Deviation / √(Sample Size)

             = 5 / √15

             ≈ 1.290

Finally, we can calculate the upper limit:

Upper Limit = Sample Mean + (Critical Value * Standard Error)

          = 75 + (2.145 * 1.290)

          ≈ 75 + 2.768

          ≈ 77.768

Therefore, the upper limit of the 95% confidence interval for the population mean is approximately 77.768.

The general form of an exponential decay function is f(a) = P . (1 - r)ᵃ, hence a function is an exponential decay if the factor (1 - r) is less than 1.

The general exponential decay function can be written as:

f(a) = P . (1 - r)ᵃ

Where:

P = initial quantity

f(a) = remaining quantity at time a

a = time period

r  = decay rate

(1 - r) = decay factor

On the other hand, the general exponential growth function can be written as:

f(a) = P . (1 + r)ᵃ

Hence, the difference between decay function and growth function is: the factor in decay faction is less than 1, while in growth function, the factor is greater than 1.

Example:

f(a) = 6 . (0.25)ᵃ

This is an exponential decay function because the factor is less than 1, that is 0.25

f(a) = 10 . (3)ᵃ

This is not an exponential decay function, but a growth function,  because the factor is greater than 1, that is 3

A polynominal function that describes an enclosure is v(x)=1500x-x2 where x is the length of the fence in feet what is the maximum area of the enclosure

Solution:

The maximum area of the enclosure is gotten when the differential with respect to x of the enclosure function is equal to zero. That is:

V'(x) = 0

V(x) = x(1500 - x) = length * breadth.

This means the enclosure has a length of x and a width of 1500 - x

Given that:

v(x)=1500x-x². Hence:

V'(x) = 1500 -2x

V'(x) = 0

1500 -2x = 0

2x = 1500

x = 1500 / 2

x = 750 feet

The maximum area = 1500(750) - 750² = 562500

The maximum area = 562500 feet²
