Answer:

  • x = 4

Step-by-step explanation:

<u>Given</u>

  • DE = 3x + 2, EF = x + 5, DF = 23

<u>As per segment addition postulate</u>

  • DE + EF = DF

<u>Substituting values:</u>

  • 3x + 2 + x + 5 = 23
  • 4x + 7 = 23

100 POINTS!!!!!!!!

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!
