5x + 25 < 85
5x < 60
x < 12
To convert hour into minute: (No. of hour × 60) minutes
So, 2/5 hours = (2/5 × 60) minutes = (120/5) minutes = 24 minutes

Answer:
Option D. Strong positive correlation
Step-by-step explanation:
Like the r-value of 0.987 is positive (0.987>0) and close to 1, the correlation of the graph is a strong positive correlation
Answer:
RC = 40
Step-by-step explanation:
Note that the circumcentre is equally distant from the triangle's 3 vertices.
That is : PC = RC = QC
Equate any pair and solve for x
Using RC = PC, then
5x - 15 = 3x + 7 ( subtract 3x from both sides )
2x - 15 = 7 ( add 15 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11
Hence
RC = (5 × 11) - 15 = 55 - 15 = 40 units
