Answer:
Step-by-step explanation:
let width=x
length=3x
area=3x×x=3x²
3x²=192
x²=192/3=64
x=√64=8
width=8 m
length=3×8=24 m

Answer:
0.9
Step-by-step explanation:
Since A and B are independent hence;
P(A∩B) = P(A)P(B)
Given the following
P(A∩B) = 0.27
P(A) = 0.3
Required
P(B)
Substitute into the formula;
P(B) = P(A∩B)/P(A)
P(B) = 0.27/0.3
P(B) = 0.9
Hence the value of P(B) is 0.9
Answer: 21.1
Step-by-step explanation:
Rounding 17.411: Find the number in the tenth place 4 and look one place to the right for the rounding digit 1
. Round up if this number is greater than or equal to 5 and round down if it is less than 5
. = 17.4
Rounding 3.66: Find the number in the tenth place 6 and look one place to the right for the rounding digit 6
. Round up if this number is greater than or equal to 5 and round down if it is less than 5
. = 3.7
Add 17.4+3.7 and get 21.1
