ella [17]

Answer:

0.216

Step-by-step explanation:

Given that a certain new type of business succeeds 60% of the time.

3 such businesses   are tested for success.

Since these three businesses open (where they do not compete with each other, so it is reasonable to believe that their relative successes would be independent). we can say X no of successful businesses is Binomial

with p = 0.6 and n =3

Required probability

=The probability that all 3 businesses succeed is:

= P(X=3)\\= 0.6^3\\= 0.216

You are going to buy some cable television ads. You can get 20 spots for $1200 or 80 spots for $3200 what is the percentage disc
Lesechka [4]

Answer:

  33 1/3%

Step-by-step explanation:

When you buy 20 ads, the per-ad rate is

  $1200/20 = $60 . . . per ad

When you buy 80 ads, the per-ad rate is

  $3200/80 = $40 . . . per ad

The percentage change to the $60 price is ...

  ((new price) - (original price))/(original price) × 100%

  = ($40 -$60)/$60 × 100% = -20/60 × 100%

  = -1/3 × 100% = -33 1/3%

The higher volume purchase comes with a 33 1/3% discount.
