Answer:
75(1/3)^(n-1).
Step-by-step explanation:
This is a Geometric sequence whose common ratio is 15/75 3/15 = 1/3.
so the nth term an = a1 r^(n-1)
= 75(1/3)^(n-1).
Answer:
<em><u>$541</u></em>
Step-by-step explanation:
1). $550 - $120 = $430 left in her bank account.
2). $430 + $200 = $630 in her bank account.
3). $630 - $89 = $541 left in her bank account.
(Withdraw means removing some of your money out of your bank account, and deposit means putting money back in your bank account)
So, therefore, after all of those transactions, Ms. Lawrence's bank account has <u><em>$541.</em></u>
Hope this helps! <3
The coeficient is 2.6 so
2.6x+23.4
if you want to factor out the coeficient then divide the whole thing by 2.6
(2.6x+23.4)/2.6=x+9
2(x+3) means 2 times (x+3)
so the factored out coeficient is
2.6(x+9)
Answer:
4.) 40 Apps can be downloaded in 1 minute
5.) 0.2 or 2/10 of a miles can be traveled in 1 second
Step-by-step explanation:
4.)
So 12 seconds is = to 1/5 of a minute
So the question asks for 1 minute
This means that we need to perform 1/5 *5 to get 1 minute
If we multiply 5 to 1/5 minutes, we also need to multiply 5 to the apps
8 * 5 = 40
So that is how we solved the answer.
So DeAndre can download 40 Apps in 1 minute.
5.)
So he traveled 1/10 miles in 1/2 or 0.5 seconds.
This means we can multiply the seconds by 2 to get 1 second.
0.5 * 2 = 1
If we multiply the seconds by 2 we also need to multiply the miles traveled by 2.
So (1/10) * 2
The 2 can be rewritten as (2/1) because 2/1 is the same as 2
(2/1) * (1/10)
So we multiply straight out and get 2/10 miles traveled which can be simplified to 1/5 miles traveled.
Answer:
P(she selects the route of four specific capitals) = 1 in 2,686,320 or 3.72 x 10⁻⁷
Step-by-step explanation:
Assuming that the order at which she visits each of the four cities matters, the number of possible routes is the permutation of choosing 4 out of 42 capitals:
Therefore, the probability that she selects the route of four specific capitals is 1 in 2,686,320 or 3.72 x 10⁻⁷
