i don't understand what you're quastion is

so let me tell you something

if you see when we go up from 1 its start to twice the number

for example

f(n)=2f(n-1)

let n equal to 2

f(2)=2f(1)

and f(1)=3

so f(2)=6

lets continue

let n equal to 3

f(3)=2f(2)

and f(2) equal to 6

so f(3)=12

so we relaised that when we go up from 1 its start to twice

and we take down number from 1 its start to take half

for example

f(n)= 2f(n-1)

let the n equal to 1

f(1)=2f(0)

f(1)=3 so

3=2f(0)

f(0)=3/2

now let the n equal to 0

f(0)=2f(-1)

f(0)=3/2

f(-1)=3/4

so we can make this equation

f(x)=3/2×(2)^x

we can sample it

so its become

f(x)=3×(2)^(x-1)

have a great day and Sorry for my bad engilish i try my best to explain

Answer:

f (1) = 3

f (n) = [f (n-1)]2

f (n) = [fn-f]2

f (n) = [fn-3]2

f (n) = 2fn-6

f (n) = 2×3-6

f (n) = 6-6

f (n) = 0

University degree requirements typically are different for Bachelor of Science degrees and Bachelor of Arts degrees. Some studen
ira [324]

Answer:

A. 0.1

B. 0.8

C. 0.5

Step-by-step explanation:

Given:

P(Science) = 0.3

P(Arts) = 0.6

P(none) = 0.2

From the above, it is understood that the events are independently events; meaning that the probability that a students gets a Bachelor of Science degree does not affect the probability of the same student getting a Bachelor of Arts degree.

A. The probability that a student gets a Bachelor of Science and Bachelor of Arts degree

Let P(Arts and Science) = the probability that a student gets a Bachelor of Arts degree and Bachelor of Science degree

For independent events,

P(A) + P(B) - P(A and B) + P(none)= 1

If we translate the above formula to suit our needs, we have something like this

P(Science) + P(Arts) - P(Arts and Science) + P(none) = 1

Or

P(Arts) + P(Science) - P(Arts and Science) + P(none) = 1

From this, we have

0.3 + 0.6 - P(Arts and Science) + 0.2 = 1

1.1 - P(Arts and Science) = 1

-P(Arts and Science) = 1 - 1.1

-P(Arts and Science) = -0.1

P(Arts and Science) = 0.1

B. The probability that a student gets a Bachelor of Science or Bachelor of Arts degree

For independent events

P(A or B) = P(A) + P(B) - P(A and B)

So, P(Arts or Science) = P(Arts) + P(Science) - P(Arts and Science)

P(Arts or Science) = 0.3 + 0.6 - 0.1

P(Arts or Science) = 0.8

C. The probability that a student gets only Bachelor of Arts

P(A only) = P(A) - P(A and B)

P(Arts) = P(Arts) - P(Arts and Science)

P(Arts) = 0.6 - 0.1

P(Arts) = 0.5

This question is worth 20 points if someone answers it! ​

The maximum number of tourists in the third week will be maximum in the numberville city.The solution of f(x)=h(x) will be x(5,2).

<h3>What are equations?</h3>

The equation is actually a relationship between the numbers and the variables.

To calculate the number of the tourists in the third week we will put the value 3 in every function:

f(x)=x^2+5x+10=(3)^2+(3\times 3)+10=29\\\\\\g(x)=3^x=3^3=27\\\\\\h(x)=10x=10\times 3=30

So we can see that the function third h(x) numberville city is having a maximum number of tourists.

The solution of f(x)=h(x) will be calculated as:

x^2-3x+10=10x\\\\\\x^2-7x+10=0\\\\\\x^2-5x-2x+10=0\\\\\\x(x-5)-2(x-5)=0\\\\\\x=5,2

Hence the solution of f(x)=h(x) will be x(5,2).

Pls help me ASAP show work please

Answer:

$3.48 for each pair of socks.

Step-by-step explanation:

It's a little confusing, because it says they're buying 2 socks, but then asks for the price of each of 2 *pairs* of socks. I'm going to believe the first sentence should say they paid for 2 pairs of socks.

They have $10, and get $3.04 in change. So we'll subtract $3.04 from $10 to find out the cost of 2 pairs of socks.

10 - 3.04 = 6.96

Then divide $6.96 by 2 pairs of socks

6.96/2 = $3.48 for each pair of socks.
