Answer:
$13,616
Step-by-step explanation:
For each year we will have to constantly decrease it by 7.5%
23,500 - 7.5%
= 21,737.5
= 21,737.5 - 7.5%
= 20,107.1875
= 20,107.1875 - 7.5%
= 18599.1484375
= 18599.1484375 - 7.5%
= 17204.2123047
= 17204.2123047 - 7.5%
= 15913.8963818
= 15913.8963818 - 7.5%
= 14720.3541532
= 14720.3541532 - 7.5%
= 13616.3275917
Definitively we will get the answer $13,616
Answer:
Step-by-step explanation:
The firm tests 75 parts, and finds that 0.25 of them are notusable
n = 75
x = 0.25 \times 75 = 18.75≈19
Confidence level = 95%
So, Z_\alpha at 95% = 1.96
Formula of confidence interval of one sample proportion:
Confidence interval
Answer:
So we already knew all three sides, there are more than one way to do it, for example:
sin∠F = HG/HF = 12/13
cos∠F = GF/HF = 5/13
tan∠F = HG/GF = 12/5
ctg∠F = GF/HG = 5/12
All of them will give you the result which is approximately 67°.
