98 points! find the radius given the linear speed and the rate of rotation. v = 32 m/2, 100 rev/min

Somebody deleted my answer before but this time my answer will be detailed

so using the formula v= r theta/ t. With r being the radius and t being the time.

Multiply 100 rev/min to 2pi

32m/ 1s = 200pir/ 1min

32m/ 1s = 200pir/ 1 min times 1 min/ 60 sec

32m/ 1 s = 100pir/ 30 s

960m = 100pir

9.6m = pir

3.06m = r

I know that I hella messed up earlier but I did try my hardest to explain this to you but this is like the easiest way I found and actually commented it on my answer earlier except IDK if you actually saw it. I apologize for earlier and I hope that I am not too late to help you out on this. I'm really sorry.

you are uyytr tyy

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
