Answer:
Step-by-step explanation:
From data give above we have
Point estimate
Jamie interval = (0.097 , 0.163)
Mariya's interval = (0.117,0.173)
Mean value of jamie interval
therefore we can say jamie interval is equal to point estimate which is equal to 0.13
Now mean of Mariyah
According to the given calculation, Mariyah interval is wrong due to mean value.
Answer:
Answer:
59.04°
58.31 inches
Step-by-step explanation:
The solution triangle is attached below :
Since we have a right angled triangle, we can apply trigonometry to obtain the angle ladder makes with the ground;
Let the angle = θ
Tanθ = opposite / Adjacent
Tanθ = 50/30
θ = tan^-1(50/30)
θ = 59.036°
θ = 59.04°
The length of ladder can be obtained using Pythagoras :
Length of ladder is the hypotenus :
Hence,
Hypotenus = √(adjacent² + opposite²)
Hypotenus = √(50² + 30²)
Hypotenus = √(2500 + 900)
Hypotenus = 58.309
Length of ladder = 58.31 inches
