The graph shows how the height of a balloon is changing over time.
Inessa05 [86]

Answer:

B. The rate at which the balloon is rising.

Step-by-step explanation:

Mathematically speaking, the slope of the line represents the change in dependent variable (Height) divided by the change in independent variable (Time). According to the graph, a postive change in time leads to a positive change in height, meaning that slope is positive. Physically speaking, the slope represents the rate of change at which the height of the ballon is rising.

Hence, correct answer is B.

The population of scores on a nationally standardized test forms a normal distribution with μ = 300 and σ = 50. If you take a ra
madreJ [45]

Answer:

P(\bar X

And using a calculator, excel or the normal standard table we have that:

P(Z

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the scores of a population, and for this case we know the distribution for X is given by:

X \sim N(300,50)  

Where \mu=300 and \sigma=50

Since the distribution for X is normal then we know that the distribution for the sample mean \bar X is given by:

\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})

We can find the individual probability like this:

P(\bar X

And using a calculator, excel or the normal standard table we have that:

P(Z
