Answer:

<em>Chase had a 6.3% error</em>

Step-by-step explanation:

<u>Percent Error</u>

If the real measure of a certain magnitude is M and the experimental measure is N, then the error is N-M.

To express that difference as a percentage, we divide by the real measure:

\displaystyle pct=\frac{N-M}{M}\cdot 100\%

The actual length of the line is M=9.5 inches, but Chase measured N=8.9 inches, thus the percent error is:

\displaystyle pct=\frac{8.9-9,5}{9.5}\cdot 100\%

\displaystyle pct=\frac{-0.6}{9.5}\cdot 100\%

pct = -6.316%

To the nearest tenth:

pct = -6.3%

Chase had a 6.3% error

Nutka1998 [239]

Answer: 1.303639

Step-by-step explanation:

The t-score for a level of confidence (1-\alpha) is given by :_

t_{(df,\alpha/2)}, where df is the degree of freedom and \alpha is the significance level.

Given : Level of significance : 1-\alpha:0.80

Then , significance level : \alpha: 1-0.80=0.20

Sample size : n=40

Then , the degree of freedom for t-distribution: df=n-1=40-1=39

Using the normal t-distribution table, we have

t_{(df,\alpha/2)}=t_{39,0.10}=1.303639

Thus, the t-score should be used to find the 80% confidence interval for the population mean =1.303639

Harlamova29_29 [7]

Answer:

He has 4 more to hang

Step-by-step explanation:

13 total; you  must add the 5 he already hung in the morning plus, the 4 he hung in the afternoon; leaving you with 4 because 5 plus 4 is 9. 13 minus 9 is 4.
