Well there is a lot of trigonometry in this. I will try my best.
Finding: Distance between Wall A and Wall B.
1. Trig and phythagorean properties for left triangle.
30m
2. Trig and Pythagorean properties for right triangle.
40m (approx)
30 + 40 = 70.
Therefore the distance is APPROXIMATELY 70 meters. I haven't learned trig yet so sorry if I am wrong.
Answer: [a] 95% confidence interval = 4.4 < Ẍ <9.2
[b] margin of error = ± 2.4
Step-by-step explanation:
here let us carefully look into this problem,
from the question, we have that Ẍ = 6.8, and SE = 1.2
let us begin
(a). asked to calculate the 95% confidence interval we have;
95% C.I = Ẍ ± 2 (SE) = 6.8 ± 2(1.2) = 6.8 ± 2.4
95% C.I = (4.4, 9.2)
this gives the confidence interval to be (4.4 < Ẍ < 9.2).
(b). the error margin is ± 2.4, which implies that our estimate of 6.8 pounds is within 2.4 pounds of the true mean weight gain for the population.

Answer:
x=38
Step-by-step explanation:
hope this helps!
if angles are on a line like that, both equations added up together will always be equal to 180.
like this:
2x-10+3x = 180
5x-10=180 (combine)
5x=190 (subtract 10 on both sides)
x=38 (divide both sides by 5)
