Answer:
x < <em>-11.4285......</em>
Step-by-step explanation:
<u>Step 1: Subtract 10 from both sides</u>
3.5x + 10 - 10 < -30 - 10
<em>3.5x < -40</em>
<u>Step 2: Divide both sides by 3.5</u>
3.5x / 3.5 < -40 / 3.5
<em>x < -11.4285......</em>
Answer: x < <em>-11.4285......</em>
In the question "Ben is travelling home to Birmingham on the M1 and M42. Both motorways have road works.
He has a fifty-fifty chance of getting delayed on the M42 and a 75% chance of being delayed on the M1.
What are the chances that he will not be delayed on his journey?"
The chance that he will not be delayed in his journey is the chance that he will not be delayed on the M1 and<span> he will not be delayed on the M42.
Probability of getting delayed on the M1 = 75% = 0.75
Probability of not being delayed on the M1 = 1 - 0.75 = 0.25
Probability of getting delayed on the M42 = 50% = 0.5
Probability of not being delayed on the M42 = 1 - 0.5 = 0.5
Probability of not being delayed on the M1 and not being delayed on the M42 = 0.25 x 0.5 = 0.125 = 1 in 8</span>
the answer is "a" because If it was proportional out of 50 there would be 15 english majors.
