Step-by-step explanation:
Assuming the decay factor, m = 0.0005
f(x) = 
f(9000) =
= 1 - 0.0111 = 0.99
Answer:
The probability of scoring 1, 3, or 5 points with one randomly thrown dart is equal to divide the area of the largest circle by the area of the square game board
step 1:
Find the area of the square game board
"A=b^{2}"
we have
b=20cm
"substitute"
A=20^{2}
=400cm²
step 2:
Find the probability
P=314/400
=0.785
=0.785 x 100
=78.5%
Answer:
c
Step-by-step explanation:
Option D:
160 plastic cubes can fit into the box.
Solution:
Convert mixed fraction into improper fraction.
Length of the box = 4 ft
Width of the box =
ft
Height of the box = 2 ft
Volume of the box = length × width × height

= 20 ft³
Volume of the box = 20 ft³
Length of the plastic cube =
ft
Volume of the cube = length × length × length

Volume of the cube = 0.125 ft³

= 160
Number of plastic cubes = 160
Hence 160 plastic cubes can fit into the box.
Option D is the correct answer.
