erastovalidia [21]

Answer:

(ai) The correct answer is the first option;  The amount of tax the student is willing to add to a gallon of gasoline.

(aii) The correct answer is the last option; Whether the student believes that global warming is a serious issue or not.

(b)  The correct answer is the first option; two-sample t interval

Step-by-step explanation:

A response variable in statistics is the idea or concept of needs to be proven right or wrong. It remains a response variable until it has been proven.  

An explanatory variable simply means an independent variable. It doesn't depend on any other variable and at the same time, it can be manipulated.

In construct a 95% confidence interval to compare the two groups, two-sample t test is the appropriate t test to use.

Davison Electronics manufactures two LCD television monitors, identified as model A andmodel B. Each model has its lowest possib
shtirl [24]

The question is incomplete. The complete question is :

Davison Electronics manufactures two LCD television monitors, identified as model A and model B. Each model has its lowest possible production cost when produced on Davison’s new production line. However, the new production line does not have the capacity to handle the total production of both models. As a result, at least some of the production must be routed to a higher-cost, old production line. The following table shows the minimum production requirements for next month, the production line capacities in units per month, and the production cost per unit for each production line:

                      Production per unit                         Minimum production

Model        New Line        Old Line                              requirements

A                   $30                $50                                          50,000

B                   $25                $40                                           70,000

Production  80000          60000

line capacity.

Let

AN- Units of model A produced on the new production line

AO Units of model A produced on the old production line

BN Units of model B produced on the new production line

BO Units of model B produced on the old production line

Davison's objective is to determine the minimum cost production plan. The computer solution is shown in Figure 3.21.

a. Formulate the linear programming model for this problem using the following four constraints:

Constraint 1: Minimum production for model A

Constraint 2: Minimum production for model B

Constraint 3: Capacity of the new production line

Constraint 4: Capacity of the old production line  

Solution :

<u>Linear programming model</u>:

Linear programming is defined as a mathematical model where the linear function is either minimize or maximize when they are subjected to some constraints.

The linear programming model is determined as follows :

Minimum : 30 AN + 50 AO + 25 BN + 40 BO

This is subject to the constraints as :

AN+AO \geq 60,000

BN+BO \geq 70,000

AN+BN \leq 80,000

AO+BO \leq 60,000

What is the quotient? 5/4c^2÷15/7c assume c is not equal to 0​
BaLLatris [955]

Answer:

<em>The quotient is \frac{7}{12c}</em>

Step-by-step explanation:

Given expression is:  \frac{5}{4c^2}\div \frac{15}{7c}

<em>While dividing two fractions, first we need to change the division sign into multiplication and then flip the second fraction. </em>

So, we will get.....

\frac{5}{4c^2}\div \frac{15}{7c}\\ \\ =\frac{5}{4c^2}\times \frac{7c}{15}\\ \\ =\frac{35c}{60c^2}\\ \\ = \frac{7}{12c} \ \ [Dividing\ both\ numerator\ and\ denominator\ by\ 5c]

So, the quotient is \frac{7}{12c}

lee is making chocolate chip cookies and the recipe calls for 3/4 cup of chocolate chips. if she wants to make 2/3 of the recipe
Marysya12 [62]

<span>
First, (again lol) you multiply the amount of chocolate chips the recipe calls for by the amount Lee wants to make.</span>

<span />so its 3/4 * 2/3

<span> =</span>

<span>6/12</span>

<span>1/2</span>

<span>Lee will need a fraction of 1/2 of a chip of chocolate chips for the recipe</span>
