1 answer:
Answer:
Option 3
Step-by-step explanation:
Given inequality is,
To find the solutions of the given inequality solve this inequality first.
This inequality will be represented by an arrow starting from 7 and directing towards infinity.
Since, inequality is having a sign notation of greater than equal to, arrow will start with a dark circle located at 7.
Therefore, Option 3 (from the top) will be the answer.

The difference in unit prices of Jalen's and Tia's juice packs is $0.15
<em><u>Solution:</u></em>
Given that,
<em><u>Jalen bought 24 juice packs for $7.20</u></em>
Unit price means price per juice pack
Unit price is found by dividing 7.20 by 24
Thus unit price of Jalen is $ 0.3
<em><u>Tia bought six juice packs for $2.70</u></em>
Unit price is found by dividing 2.70 by 6
Thus cost per pack of Tia is $ 0.45
<em><u>Difference in the unit prices of Jalen and Tia juice pack</u></em>
Difference = $ 0.45 - $ 0.3
Difference = $ 0.15
Thus the difference in unit prices of Jalen's and Tia's juice packs is $0.15
Answer:
The probability distribution of the number of customers that enter the store on a given day is:
Step-by-step explanation:
To calculate a parameter for the given day, we have to calculate what is the average arrival rate for the day.
This can be done with the data given:
1) From 10 to 12, 8 arrival/hour: 16 expected arrivals in this period
2) From 12 to 2, 8 to 12 arrival/hour (average: 10 arrivals): 20 expected arrivals in this period.
3) From 2 to 5, from 10 to 4 arrival/hour (average: 7 arrivals): 21 expected arrivals in this period.
The total expected arrivals in a day are: 16+20+21=57 arrivals/day.
Then, the probability distribution of the number of customers that enter the store on a given day is:
