Answer: D. The probability of a time from 75 seconds to 250 seconds.
Step-by-step explanation:
We know that a density curve graph for all of the possible values from a to b can be used to find the the probability of the values from a to b .
Given: A density graph for all of the possible times from 50 seconds to 300 seconds.
Then it can be used to find the the probability of a time in the range from 50 seconds to 300 seconds.
From all the given option only option D gives the interval which is lies in the above range.
i.e A density graph for all of the possible times from 50 seconds to 300 seconds can be used to determine the probability of a time from 75 seconds to 250 seconds.
i know the answer to be "B" because we just learned this in class
Answer:Rearrange the equation by subtracting what is to the right of the greater equal sign from both sides of the inequality :
9*x-4-(95)≥0
Step by step solution :
STEP
1
:
Pulling out like terms
1.1 Pull out like factors :
9x - 99 = 9 • (x - 11)
Equation at the end of step

:
STEP
2
:
2.1 Divide both sides by 9
Solve Basic Inequality :
2.2 Add 11 to both sides
x ≥ 11
