The total weight is 2 1/2 lbs
Rock A is 1/7 of the total weight....so it is 1/7 of 2 1/2 lbs..." of " means multiply
1/7 * 2 1/2 =
1/7 * 5/2 =
5/14 lbs <==
Answer:
The original number is (i)
The whole amount is (ii)
Step-by-step explanation:
So when finding a number in a percent you wanna see how much that percent will go into that number. So like if I said how many times does 60% go into 200 you would have to see how many times the number 200 would go into 60%. does this make sense? If so this is how you can find your answer.
Sorry if I'm wrong I hope you get this right!! Stay beautiful ❤️
Answer:$4.36
Step-by-step explanation:
5(0.8)= 4
4(1.09) = $4.36
Answer:
(1) Not conditional, 5/8
(2) Not conditional, 1/12
(3) Conditional, 1/18
Step-by-step explanation:
Fraction of cars sold
Altima = 1/2
Maxima = 1/3
Sentra = 1 - (1/2 + 1/3) = 1 - 5/6 = (6 - 5)/6 = 1/6
Fraction of cars sold with moon roof
Altima = 3/4 × 1/2 = 3/8
Maxima = 1/2 × 1/3 = 1/6
Sentra = 1/2 × 1/6 = 1/12
(1) Probability (a randomly selected car has a moon roof) = 3/8 + 1/6 + 1/12 = (9+4+2)/24 = 15/24 = 5/8
(2) Probability (a randomly selected car has a moon roof given it is Sentra) = 1/12
(3) Probability (a randomly selected car is a Maxima if it has a moon roof) = 1/3 × 1/6 = 1/18
A conditional probability uses if (as a condition) in making statements or asking questions
An unconditional probability makes statement or ask question without the use of condition (if)
I think the answer mightttttt beeeee hmmm
