How would you characterize the relationship between the hours spent on homework and the test scores

Mathematics

6 0

Answer and explanation:

I would characterize the relationship as a positive correlation. I would probably give it a 0.7, which means that the correlation is relatively strong. Also, this is an example of correlation, not causation, because there is not scientific proof that doing homework more will cause better grades. Hope this helps!

In a dance competition, a participant has to score a total of at least 30 points in the first four rounds combined to move on to
Anvisha [2.4K]

Answer:

5 + 3p ≥ 30

Step-by-step explanation:

"at least" means greater than are equal to. ≥

So we already know he has 5 points, but the other 3 rounds we don't. 5 + 3p

30 is the overall points he has.

5 + 3p ≥ 30

Need help sovling this for class
Reil [10]

By the knowledge and application of <em>algebraic</em> definitions and theorems, we find that the expression - 10 · x + 1 + 7 · x = 37 has a solution of x = 12. (Correct choice: C)

<h3>How to solve an algebraic equation</h3>

In this question we have an equation that can be solved by <em>algebraic</em> definitions and theorems, whose objective consists in clearing the variable x. Now we proceed to solve the equation for x:

  1. - 10 · x + 1 + 7 · x = 37     Given
  2. (- 10 · x + 7 · x) + 1 = 37   Associative property
  3. -3 · x + 1 = 37     Distributive property/Definition of subtraction
  4. - 3 · x = 36     Compatibility with addition/Definition of subtraction
  5. x = 12     Compatibility with multiplication/a/(-b) = -a/b/Definition of division/Result

By the knowledge and application of <em>algebraic</em> definitions and theorems, we find that the expression - 10 · x + 1 + 7 · x = 37 has a solution of x = 12. (Correct choice: C)

y = m * x + b,

where:

m is the slope; and

b is the intercept of the y-axis.

Factor the following quadratic.<br> y=2x^2 - 5x - 3
Reptile [31]

Answer:

(2x + 1)(x - 3)

Step-by-step explanation:

y = 2 {x}^{2}  - 5x - 3

2 {x}^{2}  - 5x - 3 = 0

(2x + 1)(x - 3)  = 0

x =  -  \frac{1}{2}

x = 3
