The answer would be 43.68
<u>Part 1</u>
The gradient of the line is , so the equation is .
This means the system is
<u>Part 2</u>
Substituting in the coordinates (-3,11) and (2,1) into the equation of the parabola,
Subtracting the equations, we get 10=5a, and thus a = 2
Substituting a = 2 back into the system, we get b = -7
<u>Part 3</u>
The equation of the parabola is , and the turning point is at . Therefore, the value of y is -7
Answer:
0.65 or 65%
Step-by-step explanation:
Students in class (n) = 40
Physics majors (P) = 14
Female students (F) = 18
Female Physics majors (P and F) = 6
The probability that a randomly selected student is female or a physics major is given by the probability that the student is female, added to the probability that the student is a physics major, subtracted by the probability of the student being a female physics major:
The probability that a randomly selected student is female or a physics major is 0.65 or 65%.
Answer:
0
Step-by-step explanation:
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.
Hence, -96 + 96 = 0
Answer:
A probability model is a mathematical scenario of a random phenomenon. It mostly deals with outcomes and percentages :0
