Answer:
The graph that matches is D.
Answer:
a
Step-by-step explanation:
given
3(x - 2) < 18 ← distribute the left side
3x - 6 < 18 ( add 6 to both sides )
3x < 24 ( divide both sides by 3 )
x < 8 → a

All numbers 0+
Step-by-step explanation:
1-1=0
2-2=0
3-3=0
And so on. Any number 0 and up minus itself= 0.
Answer:
The probability that the amount of gas in Sarah's car is exactly 7 gallons is 0.067.
Step-by-step explanation:
Let the random variable <em>X</em> represent the amount of gas in Sarah's car.
It is provided that .
The amount of gas in a car is a continuous variable.
So, the random variable <em>X</em> follows a continuous uniform distribution.
Then the probability density function of <em>X</em> is:
For a continuous probability distribution the probability at an exact point is 0.
So, to compute the probability that the amount of gas in Sarah's car is exactly 7 gallons use continuity correction on both sides:
P (X = 7) = P (7 - 0.5 < X < 7 + 0.5)
= P (6.5 < X < 7.5)
Thus, the probability that the amount of gas in Sarah's car is exactly 7 gallons is 0.067.
