Answer:
A rectangle has four right angles, A triangle has 3 sides, A square has 4 equal sides
Step-by-step explanation:
Mean : m = 2.2
Standard deviation: s = 0.3
m - 1 s = 2.2 - 0.3 = 1.9
m + 1 s = 2.2 + 0.3 = 2.5
For the normal distribution the values less than 1 standard deviation away from the mean account for 68.27 % of the set.
Answer: D ) 68 %
I would first convert the mixed fraction into an improper fraction. To put it lightly, the reciprocal is the numerator and denominator are switched. For this instance it would be 4/37.
If the squares are 4 inches then the height of the sides will be 4 inches, so you multiply the area of the base times 4!
