Answer:

The answer is -2

Step-by-step explanation:

From the direction, we know the slope is negative.

Using the slope equation, m = (y2 - y1) / (x2 - x1)

= (1 - 3) / (1 -0)

= -2

Answer:

-2

Step-by-step explanation:

slope = (y1-y2)/(x1-x2)

= (3-1)/(0-1)

= 2/-1

= -2

Value of m varies directly as value of n and n=5 when m=12. What is n when m=18?

ohaa [14]

Simplify the problem down, so:

m = 12 & n = 5
m = 6 & n = 2.5 <span>(divided each number by 20)
</span>
Now m is a factor of 18. Multiply each number by 3.
Answer: m = 18 & <span>n = 7.5</span>

In a normal distribution, what is the probability that a data value will fall below the

Serga [27]

Answer:

A 99.96%

Step-by-step explanation:

The z score shows by how many standard deviations the raw score is above or below the mean. The z score is positive if the raw score is above the mean while the z score is negative if the raw score is below the mean. The z score is given by:

$z=\frac{x-\mu}{\sigma} \\\\where\ z=z-score,\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation\\\\For\ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }$

The probability can be gotten from the normal distribution table. Therefore from the normal table:

P(z < 3.37) = 0.9996 = 99.96%
