Answer:

This is an example of causation because the patient that took the medication recovered quicker than the patient that did not.

Step-by-step explanation:

Correlation is a statistical technique that shows that a relation exists between 2 variables but does not give any explanation about the relationship

Example: Correlation between Air Conditioner sales and sunglasses sold.

As the sales of the air conditioner is increasing so do the sales of sunglasses.

Causation is a statistical technique that shows a relation ship between 2 variable. It emphasizes the fact that any change in the value of one variable will cause a change in the value of another variable.

Factor the following polynomial completely.<br> 2x2 – 10x – 28

erastovalidia [21]

Answer:

2(x - 7)(x + 2)

Step-by-step explanation:

Given

2x² - 10x - 28 ← factor out 2 from each term

= 2(x² - 5x - 14) ← factor the quadratic

Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)

The factors are - 7 and + 2 , since

- 7 × 2 = - 14 and - 7 + 2 = - 5 , thus

x² - 5x - 14 = (x - 7)(x + 2) and

2x² - 10x - 28 = 2(x - 7)(x + 2)

1. Simplify.

mrs_skeptik [129]

<h2>1. The "required option c) 45" is correct.</h2><h2>2. The value of 8 − 2⋅3 + 7 = 9</h2><h2>3. The required "option c) 45" is correct.</h2><h2>4. The required "option a) 40" is correct.</h2><h2>5. The value of $3^2-2.3+5$ = 8</h2>

Step-by-step explanation:

1. We have,

$5^2$ + 20

To find, the value of $5^2$ + 20 = ?

∴ $5^2$ + 20

= 5 × 5 + 20

= 25 + 20

= 45

Thus, the "required option c) 45" is correct.

2. We have,

8 − 2⋅3 + 7

To find, the value of 8 − 2⋅3 + 7 = ?

∴ 8 − 2⋅3 + 7

= 8 - 6 + 7

= 15 - 6

= 9

Thus, the value of 8 − 2⋅3 + 7 = 9

3. We have,

$6^2+3^2$

To find, the value of $6^2+3^2$ = ?

∴ $6^2+3^2$

= 6 × 6 + 3 × 3

= 36 + 9

= 45

Thus, the required "option c) 45" is correct.

4. We have,

$2^{3} +4.8$

To find, the value of $2^{3} +4.8$ = ?

∴ $2^{3} +4.8$

= 2 × 2 × 2 + 4 × 8

= 8 + 32

= 40

Thus, the value of $2^{3} +4.8$ = 40

Thus, the required "option a) 40" is correct.

5 . We have,

$3^2-2.3+5$

To find, the value of $3^2-2.3+5$ = ?

∴ $3^2-2.3+5$

= 3 × 3 - 2 × 3 + 5

= 9 - 6 + 5

= 14 - 6

= 8

Thus, the value of $3^2-2.3+5$ = 8
