Answer:
The sequences which are geometric are
16,-8,4,-2,1
625,125,25,5,1
-15,-18,-21.6,-25.92,-31.104
Step-by-step explanation:
Geometric sequences are ones in which you multiply or divide to get the next terms in the sequence.

Ok so 2cm on the blueprint is actually 7cm in real life
2:7=1:3.5
for every cm on the map, it is 3.5 times that in real life
so total legnths
17 times 3.5+18 times 3.5+18 times 3.5+19 times 3.5=
59.5+63+63+66.5=
252
answer is 252cm
So convert 3.25 meters to centimeters, and you get 325 centimeters.
Now divide 325 by 5 (for each ribbon), and you get 65 name tags.
Therefore, she needs 35 MORE name tags to get to 100.
Multiply 35 by 5 and you get 175 MORE centimeters of ribbon.
Hope this helped!

Answer:
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447.0 gram setting.
So, Null hypothesis : 
It is believed that the machine is under filling the bags
So, Alternate hypothesis : 
n = 41
Population standard deviation = 
x = 443
We will use z test since n > 30 and we are given the population standard deviation.
Formula : 
Use z table to find p value
p value = 0.1131
α = 0.02
p value > α
So, we fail to reject null hypothesis.
So, its bag filling machine works correctly at the 447.0 gram setting.
