The "standard form" of a 2nd order poly is y = ax^2 + bx + c. Therefore, your 2 + 3x + x^2 in "standard form" is y = x^2 + 3x + 2.
X = -3/2 and is first degree

d.yes because P(Grade 12/PClub Membership) = P(Grade 12)
Step-by-step explanation:
Answer: 760 feet
Step-by-step explanation:
So, 220 feet is 1/3 of the mountain.
Now, multiply 220 x 3 = 660.
The top of the mountain is 660 feet.
The bottom of the lake is -100 feet.
Now just simply add 100 + 660 = 760
So, the total elevation change is 760 feet.
The z-score is the number of standard deviations away from the mean that a data point is. To find the value of z for which 0.9426 of values are within z deviations of the mean, this means that (1 - 0.9426) = 0.0584 are beyond this interval, and this would be divided by 2: 0.0584 / 2 = 0.0292 of values are located below -z, while another 0.0292 is above +z.
Based on z-tables, this occurs at around z = 1.89, so the interval is from -1.89 to 1.89.
