20 times .06 is $1.20 and that is your answer.
For this question, the order of the paintings matter, so we can use generic permutation formula.
P = n!/(n-r)!
where:
n= number of paintings
r = number of paintings we are picking (in this case, we are selecting all paintings, as we are rearranging the paintings)
P = 4!/(4-4)!
P = 24/0! = 24 ways
4 paintings can be arranged in 24 different ways.
Answer: I think it's
37×2×(-5+5+1/2) = inverse property of addition
37×2×(0+1/2) = commutative property
37×2×1/2 = identity property of addition
37×1 = inverse property of multiplication
37 = identity property of multiplication

Answer: Conclusion validity is the degree to which conclusions we reach about relationships in our data are reasonable.
Step-by-step explanation:
Hi!
First, find the total percent of vehicles with at least 3 people.
15% + 7% + 3% = 25%
Now find 25% of 420
Set up a proportion and cross multiply to solve.
25 * 420 = 10500
10500/100 = 105
The answer is 105 vehicles contained at least 3 people.
Hope this helped! :)
