Answer: 0.4207
Step-by-step explanation:
Let be the sample mean area.
Given: Population mean : sq. feet
Standard deviation: sq. feet
Sample size : n= 10
The probability that the sample mean area is or less if the manufacturer’s claim is true.
Required probability = 0.4207
Step-by-step explanation:
36A) AB = 4/ sin 30° = 4/ 0.5 = 8 cm
36B) AC = 4/ tan 30° = 4/ 0.577 = 6.9 cm
36C) BD = 4/sin 45° = 4/ 0.707 = 5.7 cm
36D) area of ∆ABC = ½×6.9×4= 13.8 cm²
36E) sin A = sin 30° = 0.5
Answer:
Step-by-step explanation:
y ∞ 1/x
y = k/x
Where k is the constant of proportionality
When x = 3 and y = 5
5 = k/3
Cross multiply
k = 5×3
k = 15
The equation is y = 15/x
