Answer:
need better explanation for this
1turn = 360 half a turn is 180
360+180=540
Answer:
Step-by-step explanation:
<u>Slope formula</u>
<u>Given points</u>
<u>Slope is</u>
- m = (8 - (-2))/(15 - (-10))
- m = 10/25
- m= 2/5 or 0.4
Answer:
we reject H₀
Step-by-step explanation: Se annex
The test is one tail-test (greater than)
Using α = 0,05 (critical value ) from z- table we get
z(c) = 1,64
And Test hypothesis is:
H₀ Null hypothesis μ = μ₀
Hₐ Alternate hypothesis μ > μ₀
Which we need to compare with z(s) = 2,19 (from problem statement)
The annex shows z(c), z(s), rejection and acceptance regions, and as we can see z(s) > z(c) and it is in the rejection region
So base on our drawing we will reject H₀
