1. Identify the DEPENDENT VARIABLE in the testable

1 answer:

5 0

To identify the dependent variable in the testable, look out for the variable that is affected by the other. The variable that changes as a result of another variable is the dependent variable.

In a research study, there are typically two main variables that direct the scientific enquiry. They are:

Dependent Variable, and
Independent Variable

The independent variable causes a change in the dependent variable, i.e. the dependent variable receives the effect, the independent variable is the cause of the change.

It is very easy to identify the dependent variable in any testable hypothesis once you are able to pick out which variable is causing a change in the other.

For example, let's say the topic of a research is: The Impact of Sunlight on Germination Rate of Seedlings.

Here, Sunlight is the independent variable affecting Germination Rate.

The dependent variable here would be: Germination Rate.

Therefore, to identify the dependent variable in the testable, look out for the variable that is affected by the other. The variable that changes as a result of another variable is the dependent variable.

A businesswoman wants to determine the difference between the costs of owning and leasing an automobile. She can lease a car for

Hunter-Best [27]

First we need to find the total annual costs for both the plans.

In case of leasing:
Fixed monthly cost = $420
So, yearly cost = 420 x 12 = $5040
Cost per mile = $0.08

For x miles driven, the cost per year for leasing will be = 5040 + 0.08x

In case of purchasing:
Fixed yearly cost = $4600
Cost per mile = 0.10

For x miles driven, the cost per year for leasing will be = 4600 + 0.10x

We want to find for what number of miles will the cost of leasing will be no more expensive than the cost of purchasing.

So,

Cost of leasing ≤ Cost of purchasing
5040 + 0.08x ≤ 4600 + 0.10x
440 ≤ 0.02x
22000 ≤ x

Thus, if if the number of miles driven are equal to or less than 22,000 leasing will be no more expensive than purchasing.

If the original price is $18.00and the markup is %70 what is the total

aivan3 [116]

Answer:

$30.60

Step-by-step explanation:

Please write that as 70%.

The total is the original price plus 70% of that price, or

100% plus 70%, or

170%

Change 170% to 1.70 and multiply the original price by that:

Total price including markup: 1.70($18) = $30.60
