Answer: $3.30
Explanation:
You set up a proportion where
9.25 X
------ = -----
2.8 1
Then you cross multiply and see that...
2.8X = 9.25
Then X = 9.25 / 2.8 = 3.30
Answer: 1/10
Step-by-step explanation:
given:
numbers contained in the i.d
1,4,3,7,6
1. permutations of 5 possible outcome
T = 5
= 5 * 4 * 3 * 2 *1
= 120 times.
2. permutations of 3 odd numbers
( 1,3 and 7 )
T = 3
= 3 * 2 * 1 * 2 * 1
= 12
probability of of first three digits being odd numbers
P = 12 / 120
= 1 / 10
Well since the area of one screen in 11 ft2 you would times it by 4 which is 44
and 5 which is 55 twice so its actually 154 ft2
hope this helps
