Answer:

Similarities: In both cases the initial amount is changed after a period of time.

Differences : Saving money has no risk factor and investing money has risk factor.

Step-by-step explanation:

If you put the money aside for future use rather than spending it immediately, then it is known as saving money.

For example : A saving account, a pension account, or as cash, etc.

If you put money to work to start or expand a business or project or the purchase of an asset, with the goal of earning income, then it is known as investing money.

For example : Business, real estate, etc.

Similarities: In both cases the initial amount changes after a period of time.

Differences : Saving money has no risk factor and investing money has risk factor.

A college-entrance exam is designed so that scores are normally distributed with a mean of 500 and a standard deviation of 100.

yawa3891 [41]

Answer:

The probability is 0.003

Step-by-step explanation:

We know that the average $\mu$ is:

$\mu=500$

The standard deviation $\sigma$ is:

$\sigma=100$

The Z-score is:

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

We seek to find

$P(x800)$

For P(x>800) The Z-score is:

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

$Z=\frac{800-500}{100}$

$Z=3$

The score of Z = 3 means that 800 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%

$P(x>800)=0.15\%$

For P(x<200) The Z-score is:

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

$Z=\frac{200-500}{100}$

$Z=-3$

The score of Z = -3 means that 200 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%

$P(x$
