Answer:
39
Step-by-step explanation:
We notice this is an arithmetic sequence.
14, 9, 4.
common difference = d = 14 - 9 = 5
first term a_1 = 14
Find 6th term a_6
a_n = (n -1)*d + a_1
a_6 = (6 -1)*5 + 14
a_6 = 5*5 + 14 = 25 + 14 = 39
Answer:Holly drank 12 bottles in a week.
Step-by-step explanation:
First change the fraction 1 2/5 litre into a decimal, by doing this, we can know how many litres are there in 2/5.
So= 1 2/5
= 2 ÷5 = 0.4
= 1 + 0.4 = 1.4 liters
1.4 liters is the amount of water in a bottle.
Next, also change the fraction 2 2/5 litres into a decimal.
So=2 2/5
= 2÷5 = 0.4
= 2 + 0.4 = 2.4 liters
She drinks 2.4 liters a day.
To find how many bottles she drank in 1 week, we must multiply the amount of water she drinks in a day to the days in a week.
So= 1 week= 7 days
= 1 day= 2.4 liters
So= 2.4 × 7 = 16.8
She drinks 16.8 in a week.
To find how much bottles she drank in a week, we must divide the amount of liters she drank in one week to the amount of liters are there in a bottle.
So= 16.8 ÷ 1.4= 12 bottles
Holly drinks 12 bottles in a week.
I hope this helps! I'm sorry if it's wrong and complicated.

Step-by-step explanation:
With 2 die, there are 2 ways to roll a sum of 3......1 and 2, 2 and 1
with 2 die, there are 5 ways to roll a sum of 8...2 and 6, 6 and 2, 3 and 5, 5 and 3, 4 and 4.
total of possible outcomes = (6 * 6) = 36
the probability of this happening is : 7/36
