Answer:

y = -17.25

Step-by-step explanation:

y/23 = -3/<em>4</em>

<em>by</em><em> </em><em>cross</em><em> </em><em>multiplication</em><em> </em><em>❌</em><em> </em><em> </em><em>;</em><em>;</em><em>;</em>

<em>4</em><em>×</em><em>Y</em><em> </em><em>=</em><em> </em><em>23</em><em>×</em><em> </em><em>(</em><em>-3</em><em>)</em>

<em>4y</em><em> </em><em>=</em><em> </em><em>(</em><em>-69</em><em>)</em>

<em>y</em><em> </em><em>=</em><em> </em><em>-69</em><em>/</em><em>4</em>

<h3><em>y</em><em> </em><em>=</em><em> </em><em>-17.25</em></h3>

<h3><em>I</em><em> </em><em>hope</em><em> </em><em>that</em><em> </em><em>this</em><em> </em><em>answer</em><em> </em><em>helps</em><em> </em><em>you</em></h3>

An experiment observes an integer uniformly chosen from {1.2, 3.4.5, 6, 7, 8, 9, 10, 11.12}
Brrunno [24]

Answer:

Options D & E are independent

Step-by-step explanation:

For any of the options to be independent, they have to be mutually exclusive i.e A ∩ B = 0

A) A ∩ B = {1, 2, 3}. They are not mutually exclusive and so they are not independent.

B) A ∩ B = {3}. They are not mutually exclusive and so they are not independent.

C) A ∩ B = {8}. They are not mutually exclusive and so they are not independent.

D) A ∩ B = 0. They are mutually exclusive and thus they are independent.

E) A ∩ B = 0. They are mutually exclusive and thus they are independent.

vlada-n [284]

Answer:

Below.

Step-by-step explanation:

So 4-6 to 8-12.

4 can be devised by 12, and so can 6.

4:8 6:12

If we flip them over we can find the dilation.

so?

8:4 12:6

Each can be divided by 2.

So the factor if dilation is 2.

If the discriminant, b^2-4ac is ___, a quadratic will have two real roots, two points of intersection with the x-axis.
den301095 [7]

If the discriminant, b² - 4ac is<u> positive</u>

<h3>How to complete the statement?</h3>

From the question, we have the following equation of discriminant

The discriminant (d) is calculated as

d = b² - 4ac

The solutions of a quadratic equation are dependent on the following conditions

  • If d = 0, the quadratic equation has 1 real solution
  • If d < 0, the quadratic equation has imaginary solutions
  • If d > 0, the quadratic equation has 2 different real solutions

This means that "d > 0, the quadratic equation has 2 different real solutions" implies that the discriminant is positive

Hence, the complete statement is (b) positive
