Here is the complete question:

A lumber yard has five different lengths of 2 by 4 boards. Based on cost per linear foot, which is the best deal available on 2 by 4 boards at this lumber yard?

2 × 4 BOARD PRICES

8 foot board for $2.95

10 foot board for $3.15

12 foot board for $4.10

16 foot board for $5.80

20 foot board for $6.95

Step-by-step explanation:

8 foot board for $2.95

$\frac{2.95}{8}= 0.36875$

10 foot board for $3.15

$\:\frac{3.15}{10}=0.315$

12 foot board for $4.10

$\frac{4.1}{12}=0.341$

16 foot board for $5.80

$\frac{5.8}{16}= 0.3625$

20 foot board for $6.95

$\frac{6.95}{20}= 0.3475$

Therefore, 10 foot board for $3.15 is the best deal available on 2 by 4 boards at this lumber yard. It means you should be able to get 1 board for $0.315 when you buy 10 boards.

Suppose the test scores on an exam show a normal distribution with a mean of 82 and a standard deviation of

Zanzabum

Answer:

a) Between 74 and 90

b) 81.86% of the scores are between 78 and 90

Step-by-step explanation:

a) According to the Empirical Rule, in a normal distribution, 95% of the data are within 2 standard deviations of the mean. Therefore, the range that 95% of the scores fall in is between 82-4(2)=74 and 82+4(2)=90.

b) The percent of scores that are between 78 and 90 is: normalcdf(lower,upper,μ,σ) = normalcdf(78,90,82,4) = 0.8185946784 ≈ 0.8186, or about 81.86% of the scores.
