Answer:
The adult male foot length of 24.3 cm is significantly low.
Step-by-step explanation:
We have been given that a group of adult males has foot lengths with a mean of 26.88 cm and a standard deviation of 1.13 cm. We are asked to find the range rule of thumb to determine whether he adult male foot length of 24.3 cm significantly low or significantly high.
The range rule of thumb states that usual values in a normal standard deviation lies within 2 standard deviation from mean that is
, where
.
Let us find the range of possible values.



Since 24.3 is less than lower value of range (26.62), therefore, the adult male foot length of 24.3 cm is significantly low.
<h2>False</h2>
Due to the fact that the answer we got here is incorrect, this statement is false.
First, subtract -0.85 and -0.85, we get:
-1.7
Then, add -1.7 and -3.9, we get:
-5.6
It is important to note that the answer in the statement is written as “-8.15” which is incorrect.
The correct answer is -5.6
This is why the answer is
<h3>
False</h3>

Answer:
83 cm
Step-by-step explanation:
Let the length of the rectangle be L cm and the width be W cm.
L= 2W +3 -----(1)
Perimeter of rectangle= 2(length) +2(width)
2L +2W= 246 -----(2)
Substitute (1) into (2):
2(2W +3) +2W= 246
Expand:
4W +6 +2W= 246
Simplify:
6W +6= 246
Divide both sides by 6:
W +1= 41
W= 41 -1
W= 40
∴ width of the rectangle is 40cm.
Substitute value of W into (1):
L= 2(40).+3
L= 80 +3
L= 83
Thus, the length of the rectangle is 83 cm.
