The number is 4. 15-6=8 divide that by 2 and you are left with 4

First, write an equation:

2x+6=14

We want to get x by itself, so next we should subtract 6 from both sides and get

2x=8

Finally, divide both sides by 2 and get

x=4

The number is 4

Is 95.045 greater than less than or <br> equal two 95.545
LekaFEV [45]
Less then.. The first two numbers before the decimal are the same 95.  After the decimal is where you'll see the change. Your first number is .045 and the second one is .545.. "0," is less than "5."

An analysis of the decay of 10 grams of an unstable element over time was completed and is displayed in the computer output.
Lady bird [3.3K]

The equation of the least-squared regression line is: In(Element) = 2.305 - 0.101(Time).

<h3>What is a regression line?</h3>

A regression line displays the connection between scattered data points in any set. It shows the relation between the dependent y variable and independent x variables when there is a linear pattern.

According to the given problem,

From the table we can see,

ln(Element) is the dependent variable and Time is the independent variable.

The constant = 2.305,

Time = -0.101

Hence, we can conclude, our least squared regression line will be

In (Element) = 2.305 - 0.101 (Time).
