The answer would be D. If it was a causation it would be B. But a correlation would be something like a secreted sap in the berries. A correlation is a mutual connection in two things. Mark Brainliest if this helps as I am trying to rank up! Thanks!

Which of the following is a linear function? (89 POINTS)HURRY PLSSSSS
Dennis_Churaev [7]
<h3>Solution:</h3>

A linear function is a straight line formed on a coordinate plane.

<u>To classify an equation as a linear function:</u>

  • It must not have any exponent in the equation.
  • If there is a fraction, the denominator of that fraction must not multiply by x.

If any of these two occurs in an equation, the line can form a curve in a line, which is a non-linear function. A non-linear function is a curved line formed on a coordinate plane.

<u>Option A - y = x³ + 1:</u>

  • This equation has an exponent in the variable x. Hence, this is a non-linear function.

<u>Option B - 5x/6 = y - 4:</u>

  • This equation has no exponents in the equation. Hence, this is a linear function and also our answer.

<u>Option C - y = 8x²</u>

  • This equation has an exponent in the term 8x². Hence, this is a non-linear function.

<u>Option D - y = 1/5x</u>

  • The denominator of the fraction on the RHS side is multiplied by x. Hence, this is not a linear function.

Hence, Option B is correct.

Less than 75% of workers got their job through internet resume sites. A researcher thinks it has increased.
Vera_Pavlovna [14]

Answer:

H0 : p = 0.75  against    H1: p > 0.75  One tailed test.

Step-by-step explanation:

We state our null and alternative hypotheses as

H0 : p = 0.75  against    H1: p > 0.75  One tailed test.

In this case H0 is not defined as p≤ 0.75 because the acceptance and rejection regions cannot be set up. Therefore we take the exact value of H0 : p= 0.75.

The claim is that the probability of the workers getting their job through the internet is greater than 75% or 0.75.

As H0 is supposed to be less than we choose H1 to be greater than equality.
