F(1) = 1 f(2) = 2 f(n) = f(n − 2) + f(n - 1) f(3) =?

Mathematics

PilotLPTM [1.2K]3 years ago
4 0

Answer:

3

Step-by-step explanation:

To find f(3) we just need to plug in 3 wherever we see an n

f(3) = f(3 - 2) + f(3 - 1)

f(3) = f(1) + f(2)

Since f(1) and f(2) are given, we can plug in the respective values

f(3) = f(1) + f(2) → f(3) = 1 + 2 = 3

vova2212 [387]

Answer:

14

Step-by-step explanation:

How many 1/2s are in 7? Then, write a multiplication equation and a division equation that answer the question.

Let the number of 1/2s = x

Hence:

Division Equation =

7 ÷ 1/2

Multiplication Equation =

= 7 × 2/1

= 14

There are 14 1/2s in 7

The number of defective components produced by a certain process in one day has a Poisson
kakasveta [241]

Answer:

Step-by-step explanation:

Let X be the no of defective components produced by a certain process in one day

X is Poisson with parameter = 20

Y = no of components that can be repaired

Since each component to be repaired is independent of the other Y is Binomial with p =0.60

a) P(x=15) = 0.051649

b) P(Y = 10)= Binomial prob (15,0.6) for y =10

= 0.1859

Here no of repairables X is binomial.

c) Prob for 15 produced and 10 repairable = product of a and b

= 0.009603

Solve. 3n-7+2n=8n+11
Bezzdna [24]
------------------------------------
<span>Question:
</span>------------------------------------<span>
3n - 7 + 2n = 8n + 11

------------------------------------
Combine like terms:
</span>------------------------------------<span>
5n - 7 = 8n + 11

</span>------------------------------------<span>
subtract 8n from both sides:
</span>------------------------------------<span>
-3n - 7 = 11

</span>------------------------------------<span>
Add 7 to both sides
</span>------------------------------------<span>
-3n = 18

</span>------------------------------------
Divide by -3 on both sides:
------------------------------------
n = -6

------------------------------------
Answer: n = -6

The apr of emilio's savings account is 3.2%, and interest is compounded quarterly. if emilio does not withdraw or deposit any ad
Alex73 [517]
Final value = Initial value × (mutiplier)^n

We have;
Initial value = 9300
Multiplier = 100%+3.2% = 103.2% = 1.032
Number of quarters in a year = 4

Substitute all values into the formula, we have
Final Value = 9300 (1.032)^{4}=10548.77 rounded to two dp
