Answer:
4 (-1 + 2 x)
Step-by-step explanation:
Simplify the following:
9 x - (x + 4)
-(x + 4) = -x - 4:
9 x + -4 - x
Grouping like terms, 9 x - 4 - x = (9 x - x) - 4:
(9 x - x) - 4
9 x - x = 8 x:
8 x - 4
Factor 4 out of 8 x - 4:
Answer: 4 (-1 + 2 x)

I think the correct answer is C.
Step-by-step explanation:
At the elevation 617.5 feet below the sea level temperature of the water was °F
Step-by-step explanation:
At 502.5 feet below the sea level temperature of the water is °F
When submarine dives down 115 feet deeper, water temperature drops by °F
Elevation after the submarine dove = -502.5 - 115 = -617.5 feet
This negative sign represents the elevation below the sea level.
And the temperature will be = 
= 
= 
= 
= °F
Therefore, at the elevation 617.5 feet below the sea level temperature of the water was °F

Answer: 0.0766
Step-by-step explanation:
Let x be the random team scores.
Given: Mean = 76
Standard deviation = 8.4
We assume that x follows normal distribution.
The probability that a random team scores less than 64 points = P(x<60)
Hence, the probability that a random team scores less than 64 points =0.0766
