ANSWER
EXPLANATION
It was given that:
and
Perform the scalar multiplication to obtain:
We add the corresponding components to get;
The first choice is correct.
I'm pretty sure it would be 40,000 because if i'm not mistaken you meant the nearest 10,000 since the number is 39,892.
1.) Draw a line segment somewhere on the paper and label it line m.
2.) Mark a point somewhere on the paper but not on the line, label this point r.
3.) Fold the paper on point r. Make sure the line is folded in top of itself
4.)Trace the fold with your pencil/pen
5.) label the intersection point P
Form the confidence level (99%), we calculate the "alpha" value
alpha=1-(99/100)=0.01
Now, calculate the critical probability (p-start)
p*=1-(alpha/2)=1-(0.01/2)=0.995
z-score could be calculated from p*,,,
z-score=2.57583
Now, calculate the Margin of Error:
standard deviation = s
number of adults = n
ME=(z*s)/(sqrt n)=(2.57583*12)/(sqrt 250) = 1.955
The confidence interval = mean +or- ME
= 70+1.955 or 70-1.955
So that we can conclude that the 99% confidence interval for the mean beats per minute is 68.045 and 71.955
I hope you got the idea!
Answer:
They are equal to the ones we calculated manually: β = 51.06°, γ = 98.94°; additionally, the tool determined the last side length
