A rectangle has 2 sets of 2 sides; each set has the same length or width (depending on where it is on the rectangle).
If you have 2 sides with length, which can be expressed as 2L, and 2 sides of width, which can be expressed as 2(5) because they gave you the width in the problem, and the perimeter is 16...
2L + 2(5)=16. All you have to do is solve for <em>L</em>, which means <em>length</em>.
<em />
2*5 is 10.
2L + 10 =16.
Subtract 10 on both sides.
2L = 6.
Divide both sides by 2.
L=3.
The length is 3. Let's check to make sure we're right:
2(3) + 2(5) = 16.
2*5 is 10, and 2*3 is 6. 6 + 10 is 16. We did it! I hoped this helped!

Answer: the probability that the weight will be less than 4866 grams is 0.9861
Step-by-step explanation:
Since the weights of newborn baby boys born at a local hospital are believed to have a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = weights of newborn baby boys.
µ = mean weight
σ = standard deviation
From the information given,
µ = 3571 grams
σ = 589 grams
The probability that the weight will be less than 4866 grams is expressed as
P(x < 4866)
For x = 4866,
z = (4866 - 3571)/589 = 2.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.9861
