The selling price s , of an item is S equals C plus MC where C is the cost of the item and Emma is the percent markup based on c
Evgen [1.6K]

9514 1404 393

Answer:

  M = (S -C)/C

Step-by-step explanation:

Starting with ...

  S = C + MC

we want to solve for M.

  S - C = MC . . . . subtract the term not containing M

  (S -C)/C = M . . . . divide by the coefficient of M

Solved for M, the formula is ...

  M = (S -C)/C

Find a constant c for which p(z ≥ c.= 0.1587. round the answer to two decimal places.
Vikki [24]
What you see in the z score table is P(z< a constant), for P( z≥ a number), subtract the probability from 1:
1-0.1587=0.8413
on the z score table, you will see that p(z<1.00)=0.8413
so c=1.00

Do the product 40x500 and 40x600 have the same number of zeros
VARVARA [1.3K]

No they do not have the same number of zeroes

Although the 2 products do seem like they might have the same number of zeroes, 40 x 500 and 40 x 600

both have 3 zeroes before multiplying

if we take the first 2 digits of the 2 numbers being multiplied to get an idea of the answer

 if we take 40 x 500 - 4 x 5 = 20

then theres an extra zero added

but if we take 40 x 600 - 4 x 6 = 24

no extra zeroes added to this


so if we finally look at the answers

40 x 500 = 20 000

40 x 600 = 24 000

20000 has 4 zeroes and 24000 has 3 zeroes


so the answer is no they dont have the same number of zeroes
