It is really easy it is 6
C is the answer because I did this before
Answer:
Step-by-step explanation:
Let s represent the length of the shortest side. Then the other two sides are ...
The perimeter is the sum of the lengths of the three sides, so is ...
56 ft = s + (s+6) + (2s-6) = 4s . . . . collect terms
14 ft = s . . . . . . . divide by the coefficient of s
The shortest side is 14 ft; the second side is 20 ft; the third side is 22 ft.
We use the formula:
a.
, so we then find P(-0.56 < z < 0.56) from z-tables, and this is equivalent to 0.4246.
b.
, so we find P(-1.56 < z < 1.56) from z-tables, and this value is equivalent to 0.8812.
