Answer:
Two-Factor ANOVA with replication
Step-by-step explanation:
Types of detergent used ( A,B,C ) = 3
Length of time for the washing cycle : A = 18 mins, B = 20 mins, C = 22 mins
number of laundry loads = 18
significance level = 5%
The alternative hypothesis for testing the interaction is a Two-Factor ANOVA with replication this is because the factors that have variations are the : The type of detergent and the length of time for a washing cycle while the load is constant for all.
Answer:
∠W = 73°
∠Y = 26°
∠X = 81°
Step-by-step explanation:
∠W + ∠X + ∠Y = 180°
∠W = 3x - 5
∠X = 3x - 5 + 8
∠Y = x
3x - 5 + 3x - 5 + 8 + x = 180
7x = 182
x = 182 / 7 = 26
38.5 ft tall

Step-by-step explanation:
I need to use the fact that it has exactly one root to find the y part - do I use the quadratic formula on the last bit I have written?
I have x already and z = x+iy
Answer: 245 feet
Step-by-step explanation:
Given: The height of the rocket after t seconds is represented by the formula:
[Differentiate both sides w.r.t. t]
Put
Also, 
i.e. height is maximum at t=7.
Maximum height = 
Hence, the maximum height the rocket reaches = 245 feet.
