The score of 96 is 2 standard deviations above the mean score. Using the empirical rule for a normal distribution, the probability of a score above 96 is 0.0235.
Therefore the number of students scoring above 96 is given by:
1. 12*100 - 12*5
You would use the distributive property to get this equation (it is equivalent to the original one)
2. Um... There's no actual story for this problem; sorry I can't solve this problem
Answer:
The discriminant of f is 92, and it has no real zeros
Step-by-step explanation:
The discriminant of a quadratic is 
, where the quadratic is in the form 
. The discriminant of this one is therefore:
Since the square root of a negative number is imaginary, this quadratic has no real number zeros. Hope this helps!

Answer: 2,500 blocks
Step-by-step explanation:
Hi, to answer this question we have to calculate both volumes:
Volume of a rectangular prism= length x width x height
Volume of the block = 22 x 11 x 7 = 1,694 cm3
Before calculating the volume of the wall, we have to convert the measures in m to cm:
Since:
1m = 100 cm
5 1/2 m x 100 = 550 cm (length)
3 1/2 m x 100 =350 cm (height)
Volume of the wall = 550 x 22 x 350= 4,235,000 cm3
Finally:
Volume of the wall /Volume of the block = 4,235,000 / 1,694 = 2,500 blocks.
