Answer:
first is 52°C
Step-by-step explanation:
Answer:
<u>The series:</u>
This is an AP with the first term a₁ = 10 and common difference d = 6
a) <u>Recursive formula:</u>
b) <u>Explicit formula:</u>
- aₙ = a₁ + 6(n - 1) ⇒ aₙ = 10 + 6n - 6 ⇒ aₙ = 6n + 4
c) <u>n = 5 ⇒ a₅ = ?</u>
d) <u>S₁₇ = ?</u>
- Sₙ = n(a₁ + aₙ)/2 = n(2a₁ + (n - 1)d)/2
- S₁₇ = 17(2*10 + 16*6)/2 = 986
Im gonna say that the answer is 38% but i may be wrong but its worth a shot
Congrats to all seniors!!!
Answer: x = 1
Step-by-step explanation:
we have
x tetras
3 goldfish
5 platies.
the total number of fishh in the bowl is x + 3 + 5
The probability of removing a gold fish is equal to the number of gold fish divided by the total number of fish, this is:
p = 3/(x + 3 + 5) = 1/3
3 = (1/3)(x + 3 + 5) = x/3 + 1 + 5/3
9 = x + 3 + 5
x = 9 - 8 = 1
then wemust have that x = 1
because 1 + 3 + 5 = 9
and 3/9 = 1/3
