Answer:
Plot showing the two variables (income Vs revenue) is attached
(B)
r = 0.423, weak positive correlation.
(C)
df = n-2 = 25-2 = 23
α = 0.05
one-tailed critical value T = 1.319
Test statistic T = r*Sqrt[(n-2)/(1-r²)] = 0.423*Sqrt[(25-2)/(1-0.423²)] = 2.24
Conclusion: Since 2.24 > 1.319 we conclude that there is a positive relationship between the variables.
(D)
r² = 0.423² = 0.179, so approximately 18% of the variation in revenue is explained by the variation in the number of rooms occupied.

Answer:
13260 square inches
Step-by-step explanation:
In DEF e = 100 inches f = 740 inches and angle D = 159°. Find the area of DEF to the nearest square inch
The formula to solve the above question is
1/2absinθ
a = 100 inches
b = 740 inches
θ = 159°
The area of the triangle =
1/2 × 100 × 740 × sin 159°
= 13259.61 square inches
Approximately = 13260 square inches
Therefore, the area of DEF = 13260 square inches
Answer: 35
Step-by-step explanation: The third side can be between the smallest side (8 units) and the two sides combined (25 + 8 = 32)
The third side can be anywhere from 8 - 32
