How do graphs and equations reveal information about a relationship between two quantities
fiasKO [112]
Graph and equation both shows the proportional comparison between two quantities

for example, equation y = 4x, this means, the value of 'y' will always be 4 times the value of 'x'

More complex equation such as y = 3x + 5, means that the value of 'y' equals to 5 more triples of value of 'x'

Another example is the conversion graph attached below, it shows the relationship between kilometers and miles. For example, we want to find out how many miles are in 10 kilometers, we would draw a line from the point that shows 10 km towards the graph, then across from the graph to miles, and we'd get a reading of 12 miles.

Cisnero discusses writing three stories in one weekend at Iowa, which later connects with friends workshopping stories in her apartment, to show readers how dedicated she has become to her craft. In this way, she creates the effects of a foreshadowing.

<h3>What is foreshadowing?</h3>

In literature, foreshadowing refers to the subtle reference to an event that is yet to occur.

Foreshadowing could occur or be deployed in several ways. Some of them are:

  • Through the use of dialogue
  • Through the use of symbols
  • Through the use of character reactions etc.

The class sizes of elementary school classes in a public school district are normally distributed with an unknown population mea
weqwewe [10]

Answer: (17.14,\ 22.86)

Step-by-step explanation:

The confidence interval estimate for the population mean is given by :-

\overline{x}\pm ME, where \overline{x} is the sample mean and ME  is the margin of error.

Given : Sample mean: \overline{x}=20

The margin of error for a 98% confidence interval estimate for the population mean using the Student's t-distribution : ME=2.86

Now, the confidence interval estimate for the population mean will be :-

20\pm2.86=(20-2.86,\ 20+2.86)=(17.14,\ 22.86)

Hence, the 98% confidence interval estimate for the population mean using the Student's t-distribution =  (17.14,\ 22.86)
