Answer:

  c = 15/2

Step-by-step explanation:

Multiply both sides of the equation by 9, then reduce the fraction.

  9(5/6) = c

  15/2 = c

_____

<em>Alternate methods</em>

You are usually told to "cross-multiply" which means you multiply the expression by the product of the denominators. this would give you ...

  9(5) = 6(c)

Then you would divide by the coefficient of c to get ...

  (9·5)/6 = c = 15/2

__

Since c is multiplied by 1/9, you can solve this by multiplying by the inverse of that coefficient, 9. That is what is done in the first section above. Usually, this does in one step what the "cross-multiply" method does in 2 steps.

__

The "cross multiply" step can also be done by multiplying by the least common multiple of the denominators, 18. Then you have ...

  18(5/6) = 18(c/9)

  15 = 2c

Now, dividing by the coefficient of c gives ...

  15/2 = c

What is the solution to –2(8x – 4) &lt; 2x + 5?
Contact [7]

The solution to –2(8x – 4) < 2x + 5 is x > 1/6

<h3>How to solve the inequality?</h3>

The expression is given as:

–2(8x – 4) < 2x + 5

Expand

-16x + 8 < 2x + 5

Evaluate the like terms

-18x < -3

Divide both sides by -18

x > 1/6

Hence, the solution to –2(8x – 4) < 2x + 5 is x > 1/6

The parameter used in the probability is the average number of students represented by u.
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
