Answer:
wait what is your math problem?
Step-by-step explanation:
This is a lesson in order of operations...
PEMDAS- parentheses, exponents, multiplication, division, addition, and subtraction... That is the order in which you have to proceed during any math problem..
Your question gives an excellent example of why.
8x3+4=
in this question, we would do multiplication then addition for the answer...
24 + 4 = 28
Now the other one
8 x (3+4) =
in this expression, we would do what is inside the parentheses first, the addition. Then we would multiply...
8x 7 = 56
You see we have the same numbers and we are performing the same operations, but the difference is in the order that we perform them. As you can see it does make a difference because we get a different result.
28 vs 56
At the time the cannonball reaches the ground, the vertical height of the cannonball from the ground is 0, i.e. h = 0.
Thus, the time it will take the cannonball to reach the ground is given by
Therefore, it will take the cannonball 8 seconds to reach the ground.
Answer: Fourth option is correct.
Step-by-step explanation:
Since we have given that
A be the event that the person has 2 siblings.
B be the event that the person does not have a pet.
Since they are not independent events.
Because if P(A|B) = 0.18
in case if they are independent events then, P(A|B) = P(A).
But here P(A) = 0.4
So, they are not independent events.
Hence, Fourth option is correct.
Answer:
the end is 24.6 because 30-18% is equal to 24.6
