Answer:
6√2
Step-by-step explanation:
Solving the given expression step by step:
72 = 2 × 2 × 2 × 3 × 3
Now for finding the square root we will make pair of two numbers of same values.
We have one pair of 2's and one pair of 3's and left one 2
Thus, √72 = 2 × 3 × √2 = 6√2
We rationalize denominator and change it into a simpler form as soon as possible.
Answer:
42
Step-by-step explanation:
6 faces to a cube
each face has area of 7
6*7 is 42
Answer:
As you can see, x is a variable in both 3x 2 and 7x, and the variable x is multiplied by a number. In the first term, 3x 2, 3 is multiplied by the variable, so 3 is a coefficient. With 7x, 7 is multiplied by the variable. 7 is therefore a coefficient.
We can't tell from the information given. What we do know is
P(A ∩ B) = P(A|B) P(B)
We're given the conditional probability but not the probability of the conjunction.
If we were told P(A|B)=0.8 and P(A ∩ B)=0.12 we could conclude
P(B)=P(A ∩ B)/P(A|B) = 0.12/0.8 = 0.15
but that wasn't the problem asked.
You just have to round the hundreds place and leave the rest the same so it is 3200.5641
