Answer:

5/8m - 3/8

Step-by-step explanation:

1/4 m + 3/4 m - 3/8m - 3/8

to combine m’s, change 1/4 to 2/8. And 3/4 to 6/8.

2/8 m + 6/8m - 3/8 m - 3/8

2/8+ 6/8- 3/8= 5/8

5/8m - 3/8

Answer:

5.29 units

Step-by-step explanation:

By Pythagoras theorem:

{6}^{2}  +  {x}^{2}  =  {8}^{2}  \\ 36 +  {x}^{2}  = 64 \\  {x}^{2}  = 64 - 36 \\  {x}^{2}  = 28 \\ x  = \sqrt{28}  \\ x = 5.29150262 \: units \\ x \approx 5.29 \: units

You have a list of 1,000 random, normally distributed numbers with a mean of 20 and a standard deviation of 3. Which statement i
Ludmilka [50]
You're going to have to work out the z-scores of both values in each option and see if it makes sense.

n = m + sz

The mean is 20 and the standard deviation is 3.

So let's find try the z-scores of the outer range values and determine their probabilities:

from 14-20:

n = m + sz
20 = 20 + 3z and 14 = 20 + 3z
0 = 3z and -6 = 3z
z = 0 and z = -2

So now using a z-score table, such as the one below, find the probabilities.

z = 0 is easy, it's 0.5
z = -2 is 0.02275

Subtract the smaller from the larger to get the probability of getting in the range:

0.5 - 0.02275 = 0.47725 (so times 1000, you get 477.25, which is not about 340, so this option is wrong)
---
Now trying option 2, from 17-29:

n = m + sz
29 = 20 + 3z and 17 = 20 + 3z
9 = 3z and -3 = 3z
z = 3 and z = -1

0.99865 - 0.158655 = 0.839995 (not 680, so not the answer)
---
Now trying option 3, from 20-23:

n = m + sz
23 = 20 + 3z and 20 = 20 + 3z
3 = 3z and 0 = 3z
z = 1 and z = 0

0.841345 - 0.5 = 0.341345 (close to 340, so is your answer)
