Answer:
9.7%
Step-by-step explanation:
Given:
Observed score value = 8.5
Actual score value = 7.75
Required:
Percent error to the nearest tenth
SOLUTION:
Percent error = \frac{Value_{observed} - Value_{actual}}{Value_{actual} * 100 [/tex]
Percent error = \frac{8.5 - 7.75}{7.75} * 100 [/tex]
Percent error = \frac{0.75}{7.75} * 100 [/tex]
Percent error = \frac{75}{7.75} [/tex]
Percent error = 9.7 [/tex] (nearest tenth)
Answer: 43690
Step-by-step explanation:
Answer:
1.04%
Step-by-step explanation:
Using the z-score formula, we have:
z = (X - P) / σ
z = score
x = given value
P = average
σ = standard deviation
Z = (40 - 43.7) / 1.6 = 2.31 > <u>0.9896</u> (tabulated in the z-table)
Now, with that number, we find the probability that a randomly selected worker works less than 40 hours per week.
1 - 0.9896 = 0.0104 * 100 = 1.04%
Answer:
3 1/8 or 3.125.
Step-by-step explanation:
First you would change 1 1/4 to 5/4. Then you would make a proportion of 5/4 or I like to use decimals, 1.25, over 8. Your proportion would look like: 1.25/8 = x/20. Then cross multiply 1.25 and 20 then divide your product by 8. Your final answer is 3.125 or 3 1/8. Hope this helps!
