Solve: -19 = X - 19 halppppp
Juliette [100K]

Answer:

x = 0

Step-by-step explanation:

Step 1: Write equation

-19 = x - 19

Step 2: Solve for <em>x</em>

  1. Add 19 to both sides: 0 = x
  2. Rewrite: x = 0

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

-19 = 0 - 19

-19 = -19

The sum of 4 consecutive integers is 40 what is the third number in this sequence?
Dmitry [639]
Let's represent the numbers by : x, x+1, x+2, x+3
x+x+1+x+2+x+3=40                     The third number in the sequence is x+2
4x+6=40                                           8.5+2=10.5
4x+6-6=40-6                               Therefore the third number in the sequence is
4x=34                                             10.5
4x/4=34/4
x=8.5

Professor Hartwick finds that people who tend to score low on one variable tend to score low on another variable. Professor Hart
garri49 [273]

Answer:

Option C) a positive correlation.

Step-by-step explanation:

We are given the following in the question:

" People who tend to score low on one variable tend to score low on another variable."

Correlation:

  • Correlation is a technique that help us to find or define a linear relationship between two variables.
  • 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  or decrease in one quantity leads to decrease in another quantity.
  • A negative correlation means with increase in one quantity the other quantity decreases.
  • +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.

Since, for the given case with decrease in one variable other also decreases, thus, it is an example of positive correlation. Thus, the correlation coefficient cannot be less than or equal to zero.

Thus, the correct answer is

Option C) a positive correlation.

Hi there! Can someone help me with this, i need a proper answer, i don't need LINKS or FILES for the explanations.
alexira [117]

Answer:

<u>Using below system of inequalities</u>

  • y > 2x - 3
  • y < x + 1

<u>Following the rules </u>

  • 1. Finding x- and y - intercepts
  • 2. Connecting with dotted line for each as no equal symbol present in any inequality
  • 3. Shade respective regions
  • 4. Solution is the intersection of the shades regions
  • 5. Select any three points in the solution region

<u>Line 1</u>

  • y > 2x - 3
  • x- intercept: y = 0 ⇒ 0 = 2x - 3 ⇒ 2x = 3 ⇒ x = 1.5
  • y - intercept: x = 0 ⇒ y = -3
  • Shaded region is above the line (or to the left)

<u>Line 2</u>

  • y < x + 1
  • x- intercept: y = 0 ⇒ 0 = x + 1 ⇒ x = -1
  • y - intercept: x = 0 ⇒ y = 1
  • Shaded region is below the line (or to the right)

<u>Selected points are:</u>

  • (-1, -1), (1, 1), (2, 2)
