Using SOHCAHTOA and Kenui's height and angle of depression (which is the downward angle from the horizontal ) the answer should be:
because its the Adjacent and Opposite sides use Tan;
Tan(6.8) = o/a
tan(6.8) = Distance / 219
tan(6.8)(219 = Distance
26.114 m
But because the angle of depression is the downward angle from the horizontal the answer may be Tan(83.2)(219) = 1836.589
the 83.2 coming from 90 degrees - 6.8 degrees
either way i"m still unsure because I don't see a need for the two angles or Mias involvement, sorry if I'm wrong
Answer:
1.
2. Confidence interval = [15.2, 25.2]
Step-by-step explanation:
X = 20.2
S = 5.19
n = 11
Step 1 of 2: Critical value
α = 1 - 0.99 = 0.01
df = 11 - 1 = 10
Looking at t distribution table with α = 0.01 and df = 10, we find
Step 2 of 2: 99% confidence interval
20.2 + 3.169*1.5648
20.2 + 4.9595
25.2
20.2 - 3.169*1.5648
20.2 - 4.9595
15.2
Confidence interval = [15.2, 25.2]
Hope this helps!

160. This is because u take the total(240) divide it by 18 and multiply by 12.
however, you can also simplifiy the fraction (12/18) into (2/3) and divide by the bottom denominator (3) and multiply by the top numerator. ;)
Let's do these in steps. Remember to show your work
#1. Convert into a improper fraction.
3 x 2 x 1 over 2cm.
#2. Simplify 3 x 2 to 6.
6 + 1 over 2cm.
#3. Change 6+1 to 7.
7 over 2m.
We finally get 7 over 2, but that rounded would be 7. So B would be our answer.
