Answer:
15 terms
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 20 - 10 = 30 - 20 = 10
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and d = 10 with = 150 , then
10 + 10(n - 1) = 150 ( subtract 10 from both sides )
10(n - 1) = 140 ( divide both sides by 10 )
n - 1 = 14 ( add 1 to both sides )
n = 15
The number of terms is 15
Answer:
There are 300 milk chocolates in the bag.
Step-by-step explanation:
Since there is a bag with only milk and dark chocolates, and the probability of randomly choosing a dark chocolate is 1/12, if there are 25 dark chocolates in the bag and each is equally likely to be chosen, to determine how many milk chocolates there must be the following calculation must be performed:
1 = 25
12 = X
12 x 25/1 = X
300/1 = X
300 = X
Therefore, there are 300 milk chocolates in the bag.
