Answer:
112.065
Step-by-step explanation:
so divide the triangle in two from x to wy
and you get to triangles
then using the first right angled triangle you can apply tan=opposite/adjacent
to get height as 7.56 then apply 1/2bh to get first area as 58.59
first add all angles and subtract from 180=24
then use tan to get the height as 6.9
then apply 1/2bh to get second area as 53.48
then add the two areas to get total
(after getting first one don't multiply by two)
Y = -3x + 13
Steps and the graph are on paper
I dont know if its right. it is seven hundred fifty one
Answer:
I don’t know the area but here’s a hint to help you (hint: length x with x height)
Step-by-step explanation:
Given:
μ = $3120, population mean
σ = $677, population standard deviation.
The population is normally distributed.
n = 20, sample size.
At the 95% confidence level, the confidence interval is

1.96(σ/√n) = 1.96(677/√20) = 296.71
Th confidence interval for the mean is
($2823.29, $3416.71)
Answer: ($2823.29, $3416.71)
