The decimal equivalent for 1/20 is 1 divided by 20 (you can do this on a calculator too) which is 0.05. I hope this helps!

Answer:

12,200 ft²

Step-by-step explanation:

The area of the lawn = the area of the trapezium - the area of the square

Note that area of a trapezium is h*(a+b)*(1/2), where h is the perpendicular height, and a and b are the top and bottom.

Note that the area of a square is l*w, where l is length and w is width.

Therefore, the area of the lawn = [h*(a+b)*(1/2)] + [l*w]

= [80*(100+140)*(1/2)]+[50*52]

= 9600+2600

=12200

Number defective=4
number of non-defective=total-defective
=20-4
=16
the questions asked for 1 defective
so we choose only 1 defective from 4 defective items
4C1

and for 1 non-defective
we choose only 1 non-defective from 16 non-defective items
16C1

we choose 2 items from 20 items
so 20C2

answer:
probability= [(4C1) * (16C1)] /(20C2)
=32/95

Given that f(x) = x2 − 3x + 3 and g(x) = the quantity of x minus one, over four, solve for f(g(x)) when x = 5.

Katena32 [7]

g(x) = the quantity of x minus one, over four

g(x) = (x-1)/4

g(5) = (5-1)/4

g(5) = 4/4

g(5) = 1

f(x) = x2 − 3x + 3

f(g(5)) =1^2 − 3(1) + 3

f(g(5)) = 1 - 3 + 3

f(g(5)) = 1
