Find two numbers, if Their sum is 3/5 and their difference is 7 1/5

atroni [7]

Set up a system of equations:

x + y = 0.6
x - y = 7.2

You can solve using elimination. Add the two equations together:

2x + 0y = 7.8
2x = 7.8
x = 3.9

Then plug the number back into either of the two original equations to solve for y:

3.9 + y = 0.6
y = -3.3

The two numbers are 3.9 and -3.3

Examination of court records in a particular state shows that the mean sentence length for first-offense drug dealers is 26 mont

Zigmanuir [339]

Answer and explanation:

Given : Examination of court records in a particular state shows that the mean sentence length for first-offense drug dealers is 26 months with a standard deviation of 2 months. The records show that the sentence lengths are normally distributed.

i.e. Mean $\mu=26$ , Standard deviation $\sigma=2$

Using Z-score formula,

$Z=\frac{\bar{x}-\mu}{\sigma}$

1) What is the Z score for a 23 month sentence length? What is the probability of getting a sentence below that?

The Z score value for a $\bar{x}=23$ is given by,

$Z=\frac{23-26}{2}$

$Z=\frac{-3}{2}$

$Z=-1.5$

The probability of getting a sentence below that is $P(X$

i.e. $P(X$

$P(X$

2) A defense attorney is concerned that his client's sentence was unusually harsh at 30 months. What percent of sentences are 30 months or longer? Calculate the Z score and report the area.

The Z score value for a $\bar{x}=30$ is given by,
