Answer: C
Step-by-step explanation:
(5x^2 - 2x + 14) - (x^2 + 4x - 10)
4x^2 - 6x + 24
Answer:
4
Step-by-step explanation:
Divide the coefficient of the x term by 2, then square the result. This number will be added to both sides of the equation. For the quadratic equation x2+4x=96, the coefficient of the x term is 4.
If you want to evaluate it, -4q-(-8q)+10 is changed to -4q+8q+10 (two negatives equal positive). Next, -4q+8q is 4q (since the bigger number is positive 8q, you subtract and get 4q). Finally, your answer is 4q+10. Hope this helps! :)
Answer:
The correct option is 2. At least 3 schools have participated for 6 years or more.
Step-by-step explanation:
From the given information it is clear that the first quarterly of the data is 2 and the third quarterly is 6.
The box plot is shown below.
Since 6 is third quarterly it means 6 divides the data in 75% and 25%.
So, 25% schools have participated for 6 years or more.
Number of terms =12
Therefore, at least 3 schools have participated for 6 years or more. Option 2 is correct.
