2x - 8 < 7
Add 8 to both sides
2x<15
Divide 2 on both sides
Final Answer: x<15/2 or 7 1/2 *Both answers are equivalent to each other.

One solution was found : x < 15/2

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

 2*x-8-(7)<0

Divide both sides by 2 

 x-(15/2) < 0

Solve Basic Inequality : 1.2 Add 15/2 to both sides

Inequality plot for

2.000 x - 15.000 < 0 x < 15/2
One solution was found : x < 15/2

Answer:

UCL (x bar) = 424

LCL (x bar) = 376

Step-by-step explanation:

Given:

Average calories contained, μ = 400

Standard deviation, σ = 30 calories

Sample size, n = 25

a) UCL (x bar) = $\mu+\frac{4\sigma}{\sqrt{n}}$

On substituting the respective values, we get

UCL (x bar) = $400+\frac{4\times30}{\sqrt{25}}$

UCL (x bar) = 424

Similarly,

LCL (x bar) = $\mu-\frac{4\sigma}{\sqrt{n}}$

On substituting the respective values, we get

LCL (x bar) = $400-\frac{4\times30}{\sqrt{25}}$

LCL (x bar) = 376

The coordinate −6 has a weight of 3, and the coordinate 2 has a weight of 1

Damm [24]

The weight average of the coordinates is -4

<h3>How to determine the weight average?</h3>

The complete question is given as:

The coordinate -6 has a weight of 3 and the coordinate 2 has a weight of 1. And we need to calculate the weight average

The given parameters are:

Coordinate -6 has a weight of 3
Coordinate 2 has a weight of 1.

The weight average is then calculated as:

Weight average = Sum of (Weigh * Coordinate)/Sum of Weights

So, we have:

Weight average = (-6 * 3 + 2 * 1)/(3 +1)

Evaluate the products

Weight average = (-18 + 2)/(3 +1)

Evaluate the sum

Weight average = -16/4

Evaluate the quotient

Weight average = -4

Hence, the weight average of the coordinates is -4
