Jim was thinking of a number. Jim doubles it, then adds 19 to get an answer of 70.1. What was the original number?

Novosadov [1.4K]

Answer:

25.55

Step-by-step explanation:

Let us take the number he thinked of be x .

On doubling it :-

→ N = 2x

On adding 19 :-

→ N = 2x + 19

According to Question :-

→ 2x + 19 = 70.1

→ 2x = 70.1 - 19

→ 2x = 51.1

→ x = 51.1/2

→ x = 25.55

<h3>Hence the required answer is 25.55</h3>

Answer:

Absenteeism significantly increases cost.

Step-by-step explanation:

We are given the following in the question:

The Sensor Dynamics Corporation did a scientific study on the impact of absenteeism on increased costs.

The correlation between the two was found to be 0.7

Correlation:

It is a measure of linear relationship between two quantities.

A positive correlation means that an increase in one quantity leads to an increase in another quantity

A negative correlation means with increase in one quantity the other quantity decreases.

Values between 0 and 0.3 tells about a weak positive linear relationship, values between 0.3 and 0.7 shows a moderate positive correlation and a correlation of 0.7 and 1.0 states a strong positive linear relationship.

Thus, we can say that there is a high positive correlation between absenteeism and cost.

Thus, absenteeism significantly increases cost.
