Don't get confused by the words and write it out!

What is \frac{8\sqrt{3}}{2}?

we can seperate this to what is 8 * \sqrt{3} / 2

we just cancel out the 2 with the 8. So the answer will be

4\sqrt3

Hope it helped!

Nataly [62]

Answer:

A score of 314 is needed to be in the top 25% of students who take this exam.

Step-by-step explanation:

We are given that one of the tests provided by the NAEP assesses the reading skills of twelfth-grade students. In recent years, the national mean score was 289 and the standard deviation was 37.

Let X = <u><em>scores of the tests provided by the NAEP</em></u>

The z-score probability distribution for the normal distribution is given by;

                           Z  =  \frac{X-\mu}{\sigma}  ~ N(0,1)

where, \mu = national mean score = 289

           \sigma = standard deviation = 37

Now, we have to find how high a score is needed to be in the top 25% of students who take this exam, that means;

            P(X > x) = 0.25     {where x is the required score}

            P( \frac{X-\mu}{\sigma} > \frac{x-289}{37} ) = 0.25

            P(Z > \frac{x-289}{37} ) = 0.25

In the z table, the critial value of z that represents the top 25% of the area is given as 0.6745, that is;

                        \frac{x-289}{37}=0.6745

                        {x-289}=0.6745\times 37

                        x = 289 + 24.96 = 313.96 ≈ 314

Hence, a score of 314 is needed to be in the top 25% of students who take this exam.

Answer:

1) 12

2) c=-25

3) x = -16 2/3

Step-by-step explanation:

1) ..........................

  • 6*(4-10+8) =
  • 6*(- 6+8) =
  • 6*2=
  • 12

2) ..........................

  • 34 + 2c = -16
  • 2c = - 16 -34
  • 2c = -50
  • c = -50/2
  • c=-25

3) ..........................

  • 40 = -3x - 10
  • 40+ 10 = -3x
  • -3x = 50
  • x = 50/-3
  • x=-16 2/3
