dexar [7]

Answer:

Shown below.

Step-by-step explanation:

The table showing the umber and frequency of a certain ocean's hurricanes annually from 1930 through 2005 is:

   Number:     0     1      2     3      4    5     6     7    8     11     12      

Frequency:    5    16    20   14      3    5     4     4    2      1       1

The probability of an events, say <em>E</em> is the ratio of the number of favorable outcomes to the total number of outcomes.

P(E)=\frac{n(E)}{N}

Compute the probabilities of 0 - 12 hurricanes each season as follows:

Number Frequency Probability

     0       5             0.07

     1              16                   0.21  

     2     20             0.27

     3      14             0.19

     4       3             0.04

     5       5             0.07

     6       4             0.05

     7       4             0.05

     8       2             0.03

    11       1                     0.01

    12         1              0.01

 Total     75             1.00

A stand at the farmers market sells different types of apples, as shown in the table.
goldfiish [28.3K]

The apple that costs the least per pound is Apple B.

<h3>What is the least cost?</h3>

The cost per pound for each apple will be calculated as:

= Cost / Weight

Apple A:

= Cost / Weight

= 4.90 / 4

= $1.25 per pound

Apple B:

= Cost / Weight

= $1 / 10

= $0.1 per pound

Apple C:

Cost / Weight

= $0.45 / 0.5

= $0.9 per pound

Therefore, apple B is the cheapest
