Answer:
The explicit formula is 15 + (n-1) -4
Step-by-step explanation:
The formula for an explicit formula is an = First number of the sequence (15) + (n-1)(times the amount of integers separating two different sequential numbers) which is -4.
For instance, since 15 is the first number, it will be a1 or 15. Next will be + (n-1) which is the same for every explicit sequence and the multiplier will be the difference between each number, which is -4 in the recursive sequence. As a result, the answer is 15 + (n-1) -4.
According to Stat Trek, for an expression to be binomial, it must consist of a certain number of repeated trials and can only result in two possible outcomes.
Taking A, this isn’t right as we don’t have a certain number of phones that we’re going to record the number of defective phones of. The same applies with D. Between B and C, we know that there has to be a certain number of trials. We don’t know how many trials it will take (for a fact) to find 200 defective phones, but we do know that if we select 200 phones, there will only be 200 trials. Therefore, the answer is C.
Please note that these only have two options, defective or not defective, so that isn’t an issue here.

Answer:
6 newer games and 10 older games
Step-by-step explanation:
To find how many newer games John can purchase, we divide $30 by $5. If we do the simple math in our head, we will get the answer of 6. Therefore, the amount of newer games John can purchase is 6. Now to find the amount of older games John can buy, we apply the same strategy. We take $30 and we divide it by $3. This will get us the answer of 10. Therefore, the amount of older games John can purchase is 10.
Hope this helps and if it does, don't be afraid to rate my answer as well as maybe give it a "Thanks"? (Or even better a "Brainliest"). And if it’s not correct, I am sorry for wasting your time and good luck finding the correct answer :)
Answer:
Each person should chip in $0.83
Step-by-step explanation:
Total cost =3000km(66/100)(1.20/L)
=45.46 × 1.20
=$54.55
Cost per person = ($54.55/66)
=$0.83 person
Each person should chip in $0.83
