Answer:

680 students

Step-by-step explanation:

The 68 - 95 - 99.7  rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean,  95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.

Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:

number of people that like MATH 123 = 68% of the population

number of people that like MATH 123 = 0.68 * 1000

number of people that like MATH 123 = 680 students

Zigmanuir [339]

Answer:

x> 5/4

Step-by-step explanation:

9<4(x+9)−7−25

Step 1: Simplify both sides of the inequality.

9<4x+4

Step 2: Flip the equation.

4x+4>9

Step 3: Subtract 4 from both sides.

4x+4−4>9−4

4x>5

Step 4: Divide both sides by 4.

4x/4>5/4

x>5/4

The hourly wages of a sample of 130 system analysts are given below.
atroni [7]

Answer: b. 30%

Step-by-step explanation:

  • A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.

i.e. CV=\dfrac{\sigma}{\mu}

Given: mean =  \mu=90

Variance = \sigma^2 = 729

\sigma=\sqrt{729}=27

Now, CV=\dfrac{27}{90}=0.3

in percent , CV= 0.3\times100\%= 30\%

Hence, correct option is  b. 30%.
