Answer:

Incorrect.

Step-by-step explanation:

1 toss could not change the frequency by such a large margin 0.47 ---> 0.55.

The number of heads obtained in 30 tosses = 30 * 0.47 =  14.

So if the next toss came up heads the relative frequency of heads would be

15/31 = 0.48.

Answer:

if the prices at the bottom are per pound, then:

pears = 3.7604 (3.76)

apples = 1.1385 (1.13)

peaches = 2.8122 (2.81)

total bill = 7.07

Step-by-step explanation:

pears =

1.19 x 3.16 = 3.7604 (3.76)

apples =

0.99 x 1.15 = 1.1385 (1.13)

peaches =

1.29 x 2.18 = 2.8122 (2.81)

total bill =

3.76 + 1.13 + 2.81 = x

x = 7.7

7.7 money-wise = 7.07 <em><u>(i think)</u></em>

total bill = 7.07

OR

total bill =

3.7604 + 1.1385 + 2.8122 = x

x = 7.7111

----------------

7.7111 = 7.7 = 7.07
