Answer:
Part A: (C) 16 square inches
Part B: (C) 36 square inches
Answer:
0.15%
Step-by-step explanation:
The mean is μ = 3500 and the standard deviation is σ = 500.
2500 is 2 standard deviations below the mean, which we can calculate by finding the z-score.
z = (x − μ) / σ
z = (2500 − 3500) / 500
z = -2
According to the empirical rule, 99.7% of a normal distribution is between -2 and +2 standard deviations. Which means 0.3% is outside of that. Since a normal distribution is symmetrical, half of that, or 0.15%, is less than 2 standard deviations.
So first identy the type of series by looking at the relationship, in this case it is arithmetic!
So we know it adds up by the same thing everytime which is 3/40!
Next number will be...27/40 +3/40= 30/40
Simplify 30/40, divide by 10 both 30 and 40 to get........ 3/4
So next fraction is 3/4
Answer:
A = 108 in.²
Step-by-step explanation:
The figure can be decomposed into 3 rectangles.
✔️Area of rectangle 1 = L*W
L = 8 in.
W = 6 in.
Area = 8*6 = 48 in.²
✔️Area of rectangle 2 = L*W
L = 10 in.
W = 4 in.
Area = 10*4 = 40 in.²
✔️Area of rectangle 3 = L*W
L = 5 in.
W = 4 in.
Area = 5*4 = 20 in.
✔️Area of the irregular figure = 48 + 40 + 20 = 108 in.²
Answer:
the answer is (4 + 21)(3-51) = (3-51)(4+ 21)
