Answer:

53

Step-by-step explanation:

Take the mean of each row in the accidents reported column so for example 0-4 would be 0+4/2 = 2

Then times it by the frequency which in this case is 15:

2 x 15 = 30

Do this for each rows and then add it all up:

30 + 28 + 120 + 34 = 212

Then divide it by number of row which in this case is 4:

212/4 = 53

A suit is on sale for 33% off the sale price is 536 what is the regular price
nataly862011 [7]

Answer: sale: 536

discount: 33%

33/100*536=

Step-by-step explanation:

1- I assume the cost of the suit is $536, not 536%.

So the % of the part times $536= Original price

Remember, $536 is 77% of the original price.

536x0.77=$696.10

Since the suit was 33% off, and since the sale price of the suit was $536

Then the suit was sold for 67% of its original price

Therefore, 67% of its original price (p) equals $536, or .67(p) = 536

.67p = 536

p = 536 � .67 = $800

Original price of suit was $800
