Answer:
745.44 square mm
Step-by-step explanation:
The figure can be decomposed into ...
- a semicircle of radius 12.5 mm
- a rectangle 12.5 mm by 25 mm
- a triangle 12.5 mm by 30 mm
The relevant area formulas are ...
Semicircle: A = 1/2πr² = 1/2π(12.5 mm)² ≈ 245.437 mm²
Rectangle: A = LW = (12.5 mm)(25 mm) = 312.500 mm²
Triangle: A = 1/2bh = 1/2(12.5 mm)(30 mm) = 187.500 mm²
Total area of the figure is ...
245.437 +312.500 +187.500 = 745.437 . . . mm²
The area of the figure is about 745.44 square mm.
Answer:
10 and 2
Step-by-step explanation:
One number is 8 less than the other.
10+2=12
10-8=2
10+2=12
(84÷7)+(9÷3) The parentheses are not necessary but I just put them.
I think that's what you meant. If you meant the other thing this would be the equation: (84÷7+9)÷3. Here the parentheses are nessasary
Where is the information? orz
Answer and explanation:
Given : Examination of court records in a particular state shows that the mean sentence length for first-offense drug dealers is 26 months with a standard deviation of 2 months. The records show that the sentence lengths are normally distributed.
i.e. Mean 
, Standard deviation 
Using Z-score formula,
1) What is the Z score for a 23 month sentence length? What is the probability of getting a sentence below that?
The Z score value for a 
is given by,
The probability of getting a sentence below that is 
i.e. 
2) A defense attorney is concerned that his client's sentence was unusually harsh at 30 months. What percent of sentences are 30 months or longer? Calculate the Z score and report the area.
The Z score value for a 
is given by,
The probability of getting a sentence below that is 
i.e. 
Into percentage, 
3) Would you consider a 30 month sentence harsh? Explain
Since the percentage for 30 months or greater is harsh because the smaller value of percentage of
