A major television manufacturer has determined that its 44 inch screens have a mean service life that can be modeled by a normal
Neko [114]

Answer:

P(5

And we can find this probability with thie difference:

P(-2

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-2

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 heights of a population, and for this case we know the distribution for X is given by:

X \sim N(6,0.5)  

Where \mu=6 and \sigma=0.5

We are interested on this probability

P(5

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(5

And we can find this probability with thie difference:

P(-2

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-2

John spent $75 on a shopping trip for new clothes last week. He had expected to spend $100 on clothes. table How much was the ab
kolezko [41]

Answer:

\$\ 25

Step-by-step explanation:

By definition, the absolute error is defined as:

\epsilon = |x_a - x_e|

Where:

\epsilon: is the error

x_a: is the approximate value

x_e: is the exact value

In this problem the approximate value was 100 and the exact value was 75. Then we substitute these values in the formula to find the error.

\epsilon = |100 - 75|\\\epsilon = \$\ 25

Tyler went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 300 mg of sodium and each fr
Katena32 [7]

Answer:

<u>Tyler purchased 10 cans of soup and 5 frozen dinners.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of sodium per can of soup = 300 mg

Amount of sodium per frozen dinner = 550 mg

They all collectively contain 5,750 mg of sodium

Tyler purchased twice as many cans of soup as frozen dinners

2. Determine the number of cans of soup purchased and the number of frozen dinners purchased.

Let s to represent the number of cans of soup Tyler purchased

Let d to represent the number of frozen dinners Tyler purchased

Let's write our equation of systems:

s = 2d (1st equation)

300s + 550d = 5,750 (2nd equation)

************************************************

Substituting s and solving for d in the 2nd equation:

300s + 550d = 5,750

300 * 2d + 550d = 5,750

600d + 550d = 5,750

1,150d = 5,750

d = 5,750/1,150

<u>d = 5 ⇒ s = 2 * 5 = 10</u>

<u>Tyler purchased 10 cans of soup and 5 frozen dinners.</u>

Let's prove d = 5 and s = 10 are correct:

300 * 10 + 550 * 5 = 5,750

3,000 + 2,750 = 5,750

5,750 = 5,750

<u>We proved d = 5 and s = 10 are correct</u>
