Answer:
0.3 with the hat ? the answer is first no, then it's a repeated decimal.
Step-by-step explanation:
The population of the town after 5 years will be 147089 (approx).
Step-by-step explanation:
The exponential growth equation is given by :-
f(x)=A(1+r)^x...(*)
, where A = initial population , r= rate of growth ( in decimal) and x is time.
As per given , we have
A= 13000
r=2.5%=0.025
x= 5 years
Using (*), the population of the town after 5 years would be :
f(5)=13000(1+0.025)^5=13000(1.025)^5\\\\=13000(1.13140821289)=14708.306767614708.3067676\approx147089
Hence, the population of the town after 5 years will be 147089 (approx).
1). You will have to divide 256/8 because you will need to know how many buses are needed. By dividing these two the total Number of us is needed for a total of 256 people are 32 buses in total.
2). Just divide 350/27 and you will get approximately 13 cupcakes per student. Multiply your answer to 350 divided by 27 by 27 and you will get 324. Then subtract 324 from 350 and you will get 26. So each student receives 12 cupcakes and the teacher receives 26 cupcakes. I’m sorry I’m not that sure but I answered the rest for you
3). Find the common denominator of 2/3 and 1/5 which is 15.
2/3=10/15 and 1/5=3/15
The answer will be 13/15
4). Sane thing for number 4, find a common factor between 8 and 6 which is 24
3/8=9/24
And 5/6=20/24
Add them and you will get 29/24
Since 29/24 is an improper fraction write this improper fraction as a mixed number which will be 1 5/24.
Hope this really helps for your review and good luck! :)
1 meter = 1000 millimeters.
3.2 * 1000 = 3200 millimeters
So no, 3.2 meters is not equal to 320 millimeters.
Answer:
I would say yes, reset the machine, because the sample mean of 124.9 ounces is out of the 95% confidence interval
Step-by-step explanation:
It depends on your alpha level of test.
Would you be fine if the 124.9 ounces is in a 95% confidence interval?
we know u = 125 ounces, σ = 0.30 ounces
sample mean E = 124.9 ounces n = 40
Our test statistic is Z = [(E - u) / σ ]* which follows a Standard Normal
so...
Check if P ( -1.96 < Z < 1.96) = 95% so
Z = [(E - u) / σ ]* = [ (124.9 - 125)/ 0.3 ] *
Z = (-0.1/0.3)* 6.3245 = -2.1 ... this is out of the 95% confidence interval
I would say yes, reset the machine, because the sample mean is out of the 95% confidence interval
