Answer:
<h3>Length = 29 inches</h3><h3>Width = 8 inches</h3><h3 />
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length of the rectangle
w is the width
From the question
length of a rectangular picture is 5 inches more than three times the width is written as
l = 5 + 3w
Now substitute this into the above equation
Perimeter = 74 inches
74 = 2(5 + 3w) + 2w
74 = 10 + 6w + 2w
8w = 74 - 10
8w = 64
Divide both sides by 8
w = 8 inches
Substitute w = 8 into l = 5 + 3w
That's
l = 5 + 3(8)
l = 5 + 24
l = 29 inches
<h3>Length = 29 inches</h3><h3>Width = 8 inches</h3>

Answer: Hello mate!
each school graduate has a 68% to find a job in their chosen field within a year after graduation.
And we want to know the probability for a randomly chosen group of 11 graduates to all get a job in their area within a year of graduating.
(you used the numbers 6868% and 1111, I am assuming that you write this wrong and repeated the numbers)
Ok! so each of the 11 students has the same probability of 0.68 to find the job. Then the joint probability for the 11 events ( where the events is that each one finds a job) is the product of the probability for each one.
P = (0.68)^11 = 0.01437
and if we round it to the nearest thousandth we get:
p = 0.014
