Imagine working with a younger sibling or student who is having trouble with the 9 times table. Create an algorithm to help the

student learn how to do this easily. You may need to use outside resources to help you. If you do, make sure to document where you retrieved those sources. Note: Remember an algorithm is a description on how to perform a process. Try using numbered steps or bullet points to list instructions. Your algorithm must be able to be easily followed by others so they get the same results as you did. For example, if you made an algorithm on how to make a chocolate cake, you'd want others to be able to follow it so that their cake ended up tasting as delicious as yours!

9*1=9
9*2= 18 
9*3= 27
9*4= 36
9*5 = 45
9*6 = 54
9*7= 63
9*8= 72
9*9 = 81

Have you noticed when you add ( starting from 9*2) product is always equal to 9?
Example:  9*9= 81 
8+1 = 6
Another example: 9*6 = 54
5 + 4 = 9 

Also you can do it with your hands-

9×1=09
9×2=18
9×3=27

as you can see the algorithm would most likely be deducting one from the second digit and adding it to the first digit

A CBS News/New York Times opinion poll asked 1,190 adults whether they would prefer balancing the federal budget over cutting ta
nikklg [1K]

Using the <u>normal distribution and the central limit theorem</u>, it is found that there is a 0.0166 = 1.66% probability of a sample proportion of 0.59 or less.

In a normal distribution with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.  
  • After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
  • By the Central Limit Theorem, the sampling distribution of sampling proportions of a proportion p in a sample of size n has mean \mu = p and standard error s = \sqrt{\frac{p(1 - p)}{n}}

In this problem:

  • 1,190 adults were asked, hence n = 1190
  • In fact 62% of all adults favor balancing the budget over cutting taxes, hence p = 0.62.

The mean and the standard error are given by:

\mu = p = 0.62

s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.62(0.38)}{1190}} = 0.0141

The probability of a sample proportion of 0.59 or less is the <u>p-value of Z when X = 0.59</u>, hence:

Z = \frac{X - \mu}{\sigma}

By the Central Limit Theorem

Z = \frac{X - \mu}{s}

Z = \frac{0.59 - 0.62}{0.0141}

Z = -2.13

Z = -2.13 has a p-value of 0.0166.

0.0166 = 1.66% probability of a sample proportion of 0.59 or less.
