Answer:

x + 4 = 9 + 2x - 15

Step-by-step explanation:

Since, E is between F and G.

Therefore,

FG = EF + EG

x + 4 = 9 + 2x - 15

x + 4 = 2x - 6

4 + 6 = 2x - x

10 = x

x = 10

Firstly, we have to find the mean. The mean is simply the average of the numbers, which we find by adding each number in the sequence and then dividing that result by the total amount of numbers.

13.3 + 14.3 + 15.3 + 16.3 + 17.3 = 76.5

76.5 / 5 = 15.3

Okay, so our average is 15.3.

Now, we have to subtract the mean from each number and then square the result.

(13.3 - 15.3)^2 = 4
(14.3 - 15.3)^2 = 1
(15.3 - 15.3)^2 = 0
(16.3 - 15.3)^2 = 1
(17.3 - 15.3)^2 = 4

Now we have to find the mean of those numbers!

4 + 1 + 0 + 1 + 4 = 10

10 / 2 = 2

Finally, we take the square root of that number and we have our standard deviation. =)

a function that model the number of people that receives email in week t is $P(t)=37(4)^{\frac{t}{9.1}}$ .

Step-by-step explanation:

Here we have , Tobias sent a chain letter to his friends . The number of people who receives the email increases by a factor of 4 in every 9.1 weeks , and can be modeled by a function P, which depends on the amount of time t weeks . Tobias initially sent letter to 37 friends . We need to write a function that model the number of people that receives email in week t . Let's find out:

Basically it's an exponential function as

$f(x) = e^{ax}$ , In question initial value is 37 & and for every 9.1 weeks there is increase in people by a factor of 4 i.e.
