As the average daily temperature in New York City decreases, the number of persons who are observed wearing sweaters in the work

place increases. This is an example of a __________ correlation.

If the temperature decreasing in New York leads to the number of people wearing sweaters increasing, this is <u>Negative </u>correlation.

There are several types of correlation:

  • Positive correlation - An increase in one variable leads to an increase in another variable and vice versa
  • Negative correlation - An increase in one variable leads to a decrease in another variable and vice versa
  • Zero correlation - Variables don't change in relation to one another

In this scenario we notice that when temperatures decreased, people wearing sweaters increased. This is therefore negative correlation as the variables moved in opposite directions.

In conclusion, what was observed is negative correlation.

Using the table below, complete and explain the process used for each step in solving the equation. 4c+ 12-2c = 5c - 3​
Oduvanchick [21]

Answer:

c=3

Step-by-step explanation:

4c+12-2c=5c-3  1. combine like terms

2c+12=5c-3    2. -5c on both sides

-3c+12=3      3. -12 on both sides

-3c=-9       4. /-3 on both sides

c=3

Answer:

A) x = 3 or -1

B) x = -7

C)x = -7

Step-by-step explanation:

A) x² + 2x + 1 = 2x² - 2

Rearranging, we have;

2x² - x² - 2x - 2 - 1 = 0

x² - 2x - 3 = 0

Using quadratic formula, we have;

x = [-(-2) ± √((-2)² - 4(1 × -3))]/(2 × 1)

x = (2 ± √16)/2

x = (2 + 4)/2 or (2 - 4)/2

x = 6/2 or -2/2

x = 3 or -1

B) ((x + 2)/3) - 2/15 = (x - 2)/5

Multiply through by 15 to get;

5(x + 2) - 2 = 3(x - 2)

5x + 10 - 2 = 3x - 6

5x - 3x = -6 - 10 + 2

2x = -14

x = -14/2

x = -7

C) log(2x + 3) = 2log x

From log derivations, 2 log x is same as log x²

Thus;

log(2x + 3) = logx²

Log will cancel out to give;

2x + 3 = x²

x² - 2x - 3 = 0

Using quadratic formula, we have;

x = [-(-2) ± √((-2)² - 4(1 × -3))]/(2 × 1)

x = (2 ± √16)/2

x = (2 + 4)/2 or (2 - 4)/2

x = 6/2 or -2/2

x = 3 or -1
