Step-by-step explanation:
1. Let's calculate the unit price for each brand of diapers.
A. Stay-Dry: 108 diapers for US$ 25.18
Unit price = 25.18/108
<u>Unit price = US$ 0.23</u>
B. Uber-Soft: 180 diapers for US$ 39.14
Unit price = 39.14/180
<u>Unit price = US$ 0.22</u>
C. Cuddlies: 160 diapers for US$ 38.77
Unit price = 38.77/160
<u>Unit price = US$ 0.24</u>
<u>D. James should advise his mom to purchase Uber-Soft diapers, because the unit price is the lowest.</u>
Answer: 6/40 = 3/20
Step-by-step explanation:
The experimental probability is the number of times the desired result was obtained over the number of times the experiment was carried out:
P= Time the event occurs/ Total number of trials
In this case the event we are looking for is rolling a 3 on the number cube. The total number of trials is: 40
because the student rolls the cube 40 times. and the time that he got the number 3 (the times the desired event occurs) is: 6
because he rolls a 3 on the number cube 6 times. Thus our experimental probability to roll a 3 is: P = 6/40
Cross multiply
9x=36
(9)(4)=36
x=4
