Answer:
the middle 50% of most lengths of pregnancies ranges between 255.62 days and 274.38 days
Step-by-step explanation:
Given that :
Mean = 265
standard deviation = 14
The formula for calculating the z score is 
x = μ + σz
At middle of 50% i.e 0.50
The critical value for 
From standard normal table
+ 0.67 or -0.67
So; when z = -0.67
x = μ + σz
x = 265 + 14(-0.67)
x = 265 -9.38
x = 255.62
when z = +0.67
x = μ + σz
x = 265 + 14 (0.67)
x = 265 + 9.38
x = 274.38
the middle 50% of most lengths of pregnancies ranges between 255.62 days and 274.38 days
We will start off by simplifying 4/8 to 1/2
then we will multiply the fractions because it says "of"
1/2 × 1/6=1/12
therefore the answer is C. 1/12
Answer:
Based on the model, the length of the wall is
ft, the width of the wall is
ft, and the height of the wall is
ft. The volume of the portion of security wall that Tim has constructed so far is
cu ft.
Step-by-step explanation:
Given:
The figure constructed shows a rectangular prism made up of small wooden cubes of length
.
Width of the prism =
.
To find length , height and volume of the figure.
Solution:
From the figure we can conclude that :
Length side of the prism counts 9 cubes.
Thus, length of the prism will be given as :
⇒ 
⇒ 
⇒
(Answer)
Height side of the prism counts 11 cubes.
Thus, height of the prism will be given as :
⇒ 
⇒ 
⇒
(Answer)
Volume of the prism can be given as :
⇒ 
⇒
⇒
(Answer)
