This is a compound shape. You can split it into x shapes. See Attachment
Area of a Rectangle = L × B
L = 7
B = 6
7 × 6 = 42
<h3>42 units²</h3>
Area of a Triangle = 1/2BH
B = 6
H = 1
1/2 × 6 × 1 = 3
<h3>3 units²</h3>
Area of a Triangle = 1/2BH

63
The sector is
; there are 360 degrees in a circle.
You use the formula
.
18cm is the radius, and then you square it to get 324.
Multiply 324 by
You get 63
Answer:
n = 6
Step-by-step explanation:
2 = 
multiply both sides by 3
=> n = 6
Answer:
Probability that a randomly selected woman's gestation period will be between 261 and 279 days is 0.68.
Step-by-step explanation:
We are given that the average human gestation period is 270 days with a standard deviation of 9 days. The period is normally distributed.
Firstly, Let X = women's gestation period
The z score probability distribution for is given by;
Z = 
~ N(0,1)
where, 
= average gestation period = 270 days
= standard deviation = 9 days
Probability that a randomly selected woman's gestation period will be between 261 and 279 days is given by = P(261 < X < 279) = P(X < 279) - P(X 
261)
P(X < 279) = P( < 
) = P(Z < 1) = 0.84134
P(X 261) = P( 
) = P(Z -1) = 1 - P(Z < 1)
= 1 - 0.84134 = 0.15866
<em>Therefore, P(261 < X < 279) = 0.84134 - 0.15866 = 0.68</em>
Hence, probability that a randomly selected woman's gestation period will be between 261 and 279 days is 0.68.
7/8 can be converted to .875 because 1/8 is .125 and .125*7=.875. Add -12 to it so the answer is -12.875
