L*w=A
l*9=3
(l*9)/9=3/9
l=1/3 of a meter.
Answer:
2/7 , 7/13 ,5/9,10/11
Step-by-step explanation:
5/9 , 7/13 , 2/7, and 10/11
5/9 = 0.555
7/13≅ 0.54
2/7 ≅0.29
10/11=0.90
ascending order means from least to greatest:
2/7 , 7/13 ,5/9,10/11
Answer:
4.13
Step-by-step explanation:
To find out how many kilometres they ran in all you have to do 1.43+2.7 =4.13
Answer:
E(x) = 1.43 (Approx)
Step-by-step explanation:
Given:
Total number of camera = 7
Defective camera = 5
Sample selected = 2
Computation:
when x = 0
P(x=0) = 2/7 × 1/6 = 2/42
P(x=1) = [2/7 × 5/6] + [5/7 × 2/6] = 20/42
P(x=2) = 5/7 × 4/6 = 20/42
So,
E(x) = [0×2/42] + [1×20/42] + [2×20/42]
E(x) = 1.43 (Approx)
We have to solve two inequations:
Equation 1:
30(x-1)≥0
(x-1)≥0/30
(x-1)≥0
x≥1 (solution 1)
Equation 2:
5x²≥0
x≥0
The solution is: solution1 <span>∩ solution2
Teherefore; x≥1</span>
