Step-by-step explanation:

Step 1: To calculate the time it takes to cook a 3 kg chicken, use the following equation: Time (minutes) = Mass (kg) × Constant

Step 2: Substitute 3 for the mass (kg) and solve for the time (minutes): Time (minutes) = 3 kg × Constant

Step 3: To calculate the constant, use the given information that it takes 100 minutes to cook a chicken of unknown mass (M). Substitute 100 minutes and M for the time and mass, respectively: 100 minutes = M kg × Constant

Step 4: Solve for the constant by dividing both sides by M kg: Constant = 100 minutes / M kg

Step 5: Substitute the value of the constant into the first equation and solve for the time it takes to cook a 3 kg chicken: Time (minutes) = 3 kg × (100 minutes / M kg)

Step 6: Simplify the equation to find the number of minutes it takes to cook a 3 kg chicken: Time (minutes) = 300 minutes

Therefore, it will take 300 minutes, or 5 hours, to cook a 3 kg chicken.

To calculate the mass of a chicken that takes 100 minutes to cook, use the same equation and substitute 100 minutes for the time: Mass (kg) = Time (minutes) / Constant

Substituting 100 minutes and the value of the constant, which is 100 minutes/M kg, yields Mass (kg) = 100 minutes / (100 minutes / M kg) = M kg

Therefore, the mass of a chicken that takes 100 minutes to cook is M kg.

The equation "ax2 = y," which has one solution unless a = 4, and none unless a = 4, has a solution. x = √(-4ay) / (2a) restricted by the condition that y be negative.

We may use the quadratic formula to determine the solutions to an equation for various values of an to construct a solution to the equation "ax² = y," which has no solution when a = 4 & just one solution in all other cases.

According to the quadratic formula, the answers to the problem "ax2 + bx + c = 0" are provided by

x = (-b +/- √(b² - 4ac)) / (2a)

In this formula, if we add "ax² = y," we obtain

x = (-0 +/- √(0² - 4ay)) / (2a)

which simplifies to

x = √(-4ay) / (2a)

If a = 4, the equation becomes

x = √(-16y) / 8

The equation has no solutions if y is positive because the value of (-16y) is fictitious. The value of (-16y) is real if y is negative, but the equation is still unsolvable since x cannot have a negative value. As a result, when a = 4, the problem has no solutions.

The equation has a single solution provided by any other value of a.

x = √(-4ay) / (2a)

For example, if a = 3, the equation becomes

x = √(-12y) / 6

Since √(-12y) is imaginary if y is positive, the problem has no solutions. If y is negative, √(-12y) has a real value, and there is only one solution to the problem.

Null hypothesis (H0): The population mean amount spent by customers at the restaurant is equal to or greater than $32.

Alternative hypothesis (H1): The population mean amount spent by customers at the restaurant is less than $32.

The appropriate null and alternative hypotheses in this scenario can be stated as follows:

The null hypothesis is the default assumption, which states that there is no significant difference between the mean amount spent by customers last year and this year.

On the other hand, the alternative hypothesis is the claim that the mean amount spent by customers this year is less than the previous year, which the restaurant owner is trying to test.

By conducting appropriate statistical tests and analyzing the data, the restaurant owner can either reject the null hypothesis or fail to reject it, depending on the level of significance and the strength of the evidence gathered.

Step-by-step explanation:

Answer:

To summarize the typical daily revenue of the food truck now, we would use the new mean of the daily revenue, which takes into account the new sale of $7,100. We can add this new value to the previous sum of daily revenues and divide the total by the number of days to find the new mean:

New mean = (total sum of daily revenues + $7,100) / (number of days + 1)

This would give us the updated measure of center that reflects the new data point.

The mean daily revenue of the food truck now is $6,550.

The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the sum of the total number of observations by the total number of observations.

To summarize the typical daily revenue of the food truck now, we would use the mean as the measure of the center.

We can calculate the mean daily revenue by adding the daily revenues from the two days ($6,000 + $7,100 = $13,100) and dividing by the number of days (2).

Mean daily revenue = (Total revenue) / (Number of days) = $13,100 / 2 = $6,550

Therefore, the mean daily revenue of the food truck now is $6,550.

The correct answer is 39.5

So, the gradient of f at the point (1,2,2) is: ∇f(1,2,2) = (1/2) i + (1/4) j + (1/2) k where i, j, and k are the unit vectors in the x, y, and z directions, respectively.

To find the gradient of the function f(x,y,z) at the point (1,2,2), we need to find the partial derivatives of f with respect to x, y, and z and evaluate them at the given point.

So, we have:

f(x,y,z) = (x^2 y^2 z^2)^(-1/2) ln(xyz)

∂f/∂x = (-1/2) (x^2 y^2 z^2)^(-3/2) (2xy^2 z^2) + (1/x) (x^2 y^2 z^2)^(-1/2)

= (-xy^2 z^2)/(x^2 y^2 z^2) + (1/x) (x^2 y^2 z^2)^(-1/2)

= -y^2 z^2/(x^2 y^2 z^2) + 1/xsqrt(x^2 y^2 z^2)

= -1/(xyz) + 1/x

∂f/∂y = (-1/2) (x^2 y^2 z^2)^(-3/2) (x^2 2yz^2) + (1/y) (x^2 y^2 z^2)^(-1/2)

= (-x^2 yz^2)/(x^2 y^2 z^2) + (1/y) (x^2 y^2 z^2)^(-1/2)

= -x^2/z^2 + 1/ysqrt(x^2 y^2 z^2)

= -x^2/(z^2 y) + 1/y

∂f/∂z = (-1/2) (x^2 y^2 z^2)^(-3/2) (x^2 y^2 2z) + (1/z) (x^2 y^2 z^2)^(-1/2)

= (-x^2 y^2 z)/(x^2 y^2 z^2) + (1/z) (x^2 y^2 z^2)^(-1/2)

= -x^2 y^2/(z^2 x^2 y^2) + 1/zsqrt(x^2 y^2 z^2)

= -x^2 y^2/(z^3) + 1/z

Now we can evaluate these partial derivatives at the point (1,2,2):

∂f/∂x (1,2,2) = -1/(122) + 1/1 = 1/2

∂f/∂y (1,2,2) = -1/(222) + 1/2 = 1/4

∂f/∂z (1,2,2) = -1/(122) + 1/2 = 1/2

The range of feasible values for the multiple coefficients of correlation is from -1 to 1.

The multiple coefficients of correlation, also known as the multiple R or R-squared, measures the strength and direction of the linear relationship between a dependent variable and multiple independent variables in a regression model. It quantifies the proportion of the variance in the dependent variable that is explained by the independent variables.

The multiple coefficients of correlation can take values between -1 and 1.

A value of 1 indicates a perfect positive linear relationship, meaning that all the data points fall exactly on a straight line with a positive slope.

A value of -1 indicates a perfect negative linear relationship, meaning that all the data points fall exactly on a straight line with a negative slope.

A value of 0 indicates no linear relationship between the variables.

Values between -1 and 1 indicate varying degrees of linear relationship, with values closer to -1 or 1 indicating a stronger relationship. The sign of the multiple coefficients of correlation indicates the direction of the relationship (positive or negative), while the absolute value represents the strength.

The range from -1 to 1 ensures that the multiple coefficients of correlation remain bounded and interpretable as a measure of linear relationship strength.

The value of m and t is 4- 3m/2 and 8/3 -2t/3.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side).

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.

Given:

2t+3m=8

For t:

2t= 8-3m

t= (8-3m)/2

t= 8/2 -3m/2

You will have 12 pavers left over to make a patio of 14 * 14 pavers.

To find the number of concrete pavers that are left over, we can perform the following mathematical operation:

We must check how many concrete pavers are needed to make a perfect square shape. To do this we check the square root of 208, 207, 206 and we decrease until the result is an integer.

In 196 the result is 14. So we can infer that a grid of 14 * 14 tiles would be a perfect square.

Finally, to identify how many pavers are left over, we must do the following subtraction:
