I assume you want to find the value of w
The first thing we will do is divide both sides by 0.25
4/0.25 = 0.25(w - 4.3)/0.25
The two 0.25s cancel each other. 4/0.25 = 16
16 = w - 4.3
Now we add 4.3 to both sides
16 + 4.3 = w - 4.3 + 4.3
The two 4.3s cancel each other 16 + 4.3 = 20.3
20.3 = w
w = 20.3

Answer:
P (2) = 0.1
Step-by-step explanation:
The table has X and P(X), you have to search the X and see its P(X) and thats the probability
Answer:
Step-by-step explanation:
What i would do is turn the first one into an improper fraction
7/5 x 1/4
it's easier to multiply this way
see if you can simplify any of the terms first
7 1
5 4
none of the numbers can be broken down further so we just multiply straight across
7 x 1 is 7
5 times 4 is 20
so the answer would be 7/20
