Answer:
22.44 meters
Step-by-step explanation:
First find the LCM(51,68) = 204.
So their footsteps coincide every time after Nick's 204 ÷ 51 = 4th step and his dad's 204 ÷ 68 = 3rd step.
So, in the distance of 204 cm, there will be total 6 footsteps, except in the first 204 cm when their "starting" step is counted.
The total distance will be 67 − 1 (starting step)/6 · 204=2244 cm or 22.44m.

Answer:
The sample mean is 3.48 and the margin of error is 0.44.
Step-by-step explanation:
We know that the confidence interval is written in the form "x − E to x + E", meaning x: sample mean or estimator, and E: margin of error.
To calculate the mean, we can calculate the average of both bounds of the confidence interval:
With one of the bounds, we can calculate the margin of error E

Answer:
19
Step-by-step explanation:
Here we have to find out number of people attended the party. we are given with the number of the handshakes in the party .
We are going to use the following formula to determine the number of guests
Nos. of handshakes
Here we have H = 171
Hence our equation becomes
now we solve it by splitting the middle term method
Now we have to find the factors of 342 whose difference to 1. The factors are 19 and 18 in this case. hence we slit our middle term like this
Hence
either
(x+18)=0 or (x-19) =0 Thus
x=-18 which is not possible as no of people can not be less than 0
x=19 which will our answer
