The p-value can be found with the F-distribution table or statistical software. If the p-value is less than or equal to α, then answer is option (a),If the p-value is greater than α, then answer is option (b).

To determine the correct statistical decision based on the given F-statistic, F (3, 12) = 2.72, we need additional information such as the significance level (α) of the hypothesis test. The significance level is a predetermined threshold that is used to assess the statistical significance of the results.

The correct decision depends on whether the calculated p-value, which quantifies the strength of evidence against the null hypothesis, is less than or equal to the significance level (α).

To find the p-value, you would need the F-distribution table or statistical software.

Once you have the p-value, you can compare it to the significance level (α) to make a decision:

If the p-value is less than or equal to α, you would reject the null hypothesis, indicating a statistically significant mean difference.

If the p-value is greater than α, you would fail to reject the null hypothesis, suggesting that there is not a statistically significant mean difference.

Therefore, without the significance level or the p-value, it is not possible to determine the correct statistical decision.

The value of f(3) is the equation for is  mathematically given as

f(3) = 30

This is further explained below.

In the field of mathematics, a continuous function is defined as a function that exhibits the property of inducing a continuous variation in the value of the function whenever the argument undergoes a continuous change. This indicates that there are not any rapid shifts in value, which are referred to as discontinuities.

Generally, given that, f '(x) is continuous in 3 to 1,

Therefore

∫f '(x) dx = f(x) + constant

and

\(\int ^b _a\)f '(x) dx = f(b) - f(a)

Therefore

\(\int ^3 _1\)f '(x) dx = f(3) - f(1) = 19

f(3) = f(1) + 19

f(3) = 14 + 19

f(3) = 30

In conclusion,  the value of f(3) is

f(3) = 30

we are asked to determine the surface area of the figure. To do that we need to find the areas of each face and add them together. The front face is a trapezoid, and its area is:

Where "b" is the upper base, "B" is the lower base and "h" is the height. Replacing the values:

Solving the operations:

the upper face is a rectangle, its area is the product of its side:

The area of the lower face is also a rectangle, therefore its area is:

The side face is also a rectangle, and its area is:

Now we add the areas having into account that the front and side faces repeat themselves. the total surface area is:

Solving the operations:

Therefore, the surface area is 286 square feet.

The boolean expression that is true if the value of x is equal to zero is:

x == 0

Let's us first learn about Boolean expression.

A boolean expression is an expression that evaluates to either true or false. It can be created using comparison operators, such as == (equal to), != (not equal to), < (less than), > (greater than), <= (less than or equal to), and >= (greater than or equal to). These operators compare two values and return a boolean result.

In this question, the double equal sign (==) is the comparison operator for equality in many programming languages, and it returns true if the values on both sides are equal, and false otherwise.

So in this case, the expression "x == 0" would return true if x is equal to zero, and false otherwise.

Step-by-step explanation:

The probability of Suzan getting one of each color other than fluorescent pink, given that she gets the fluorescent pink one, is 108/1001 or approximately 0.108.

To find the probability of Suzan getting one of each color other than fluorescent pink, given that she gets the fluorescent pink one, we can use counting techniques.

First, we need to find the total number of ways Suzan can choose four marbles out of the 14 in the bag. This can be calculated using combinations, which is 14 choose 4 or (14!)/(4!10!) = 1001.

Next, we need to find the number of ways Suzan can choose one of each color other than fluorescent pink, given that she already picked the fluorescent pink one. There are three red, three green, three yellow, and four orange marbles left in the bag. Suzan needs to choose one from each color, which can be done in (3x3x3x4) = 108 ways.
