The predicted volume for a time of 12 seconds of the large, cone-shaped cistern is; V = 450.485 cm³

<h3>How to Solve Regression Equations?</h3>

We are given the regression equation;

In V = -1.327 + 2.993 In T

Where;

V is volume

T is time

At T = 12, we have;

In V = -1.327 + 2.993 In 12

In V =  -1.327 + 7.4373

In V = 6.1103

V = e^(6.1103)

V = 450.485 cm³

Answer:

The correct option is the graph on the bottom right whose screen grab is attached (please find)

Step-by-step explanation:

The information given are;

The required model height for the designed clothes should be less than or equal to 5 feet 10 inches

The equation for the variance in height is of the straight line form;

y = m·x + c

Where x is the height  in inches

Given that the maximum height allowable is 70 inches, when x = 0 we have;

y = m·0 + c = 70

Therefore, c = 70

Also when the variance = 0 the maximum height should be 70 which gives the x and y-intercepts as 70 and 70 respectively such that m = 1

The equation becomes;

y ≤ x + 70

Also when x > 70, we have y ≤ \mid-x + 70\mid   with a slope of -1

To graph an inequality, we shade the area of interest which in this case of ≤ is on the lower side of the solid line and the graph that can be used to determine the possible variance levels that would result in an acceptable height is the bottom right inequality  graph.

Vera_Pavlovna [14]
Convert the mixed number 2 1/4 into an improper fraction:  9/4.

Then multiply this 9/4 by 3:  27/4, or 6 3/4.

How much would $200 invested at 7% interest compounded annually be worth after 5 years? Round your answer to the nearest cent. D
viktelen [127]
The future worth (F) of the investment at present (P) with a compound interest i after n years is calculated through the equation,
                                      F = P x (1 + i)^n
Substituting the known values,
                                      F = ($200) x (1 + 0.07)^5 = $280.51
Thus, the future worth of the investment is approximately $280.51.
