NEED AN A !!!!!!!! MATH HELP!!!!!!!
2 answers:
Plug n = 1 into the original formula to get
an = 14 - 9n
a1 = 14 - 9*1
a1 = 5
So the first term is 5
The common difference is -9 as this is the slope in front of the n term. This means each term is going down by 9 each time. Notice the second term is
an = 14-9n
a2 = 14-9*2
a2 = -4
and so on...
To get the nth term, we subtract 9 from the (n-1)st term
That's the same as saying
So all together, the rule is
Final Answer: Choice B

Answer:
The percentage of workers not wearing the helmets is 5.3 %.
Step-by-step explanation:
A safety committee randomly examined 900 construction workers during their work, and found that 48 workers were not wearing helmets. Estimate the percentage of workers who do not wear protective masks during their working time with 98% confidence
total workers = 900
Not wearing helmet = 48
Percentage which are not wearing the helmets
= %
