~30 messages per day.
Step-by-step explanation:
To get the rate at which Tristan sends text mesages per day, divide the 91 text messages sent divided by the three days they sent (3).
91/3 = 30.333 repeating.
Answer:
Step-by-step explanation:
Given
Number of Girls : 0 ----> 1 -----> 2 ------->3
Number of Families: 112 -> 314 --> 382 ---> 192
Solving (a): At most one girl
From the table, the number of families with at most one girl is: 112 + 314
i.e.
Number of Girls : 0 ----> 1
Number of Families: 112 -> 314
So, we have:
The probability is then calculated as:
Solving (b): More girls
From the table, the number of families with more girl is: 382 + 192
i.e.
Number of Girls : -----> 2 ------->3
Number of Families: --> 382 ---> 192
So, we have:
The probability is then calculated as:
A=pi(r)^2
We have the diameter. To get the radius divide it by 2.
The radius now is equal = 13.
Pi=3.14
Distribute it to the equation... A=3.14(13)^2
The area is equal = 530.66
