3.45x10^5 is the answer
slamgirl [31]4 years ago
7 0

Answer:

3.45×10^{5}

Step-by-step explanation:

The proper way to put a number in scientific notation is a specific way. So the answer you see above is the proper way you would put a number in scientific notation.

So. Put the decimal in between 3 and 4.

3.45000

Now count from the last 0 to 4. Which is 5. (Scientific notation can only be with 0's not any other number.)

So, it would be:

3.45×10^{5}

Hope this helped!

Find the sum of the first 10 terms for the sequence {21, 63, 189, . . . }.
antiseptic1488 [7]
The sum of n terms of a geometric sequence with first term "a" and common ratio "r" is given by
S_{n}=a\dfrac{r^{n}-1}{r-1}
You have a=21, r=3, so the sum of 10 terms is
S_{10}=21\cdot \dfrac{3^{10}-1}{3-1}=620004

The appropriate choice is the 2nd one:
   620,004

An oil exploration firm is formed with enough capital to finance ten explorations. The probabil- ity of a particular exploration
tensa zangetsu [6.8K]

Answer:

μ = 1 The firm expects that one oil exploration will be successful.

v(x)= 0.9

Step-by-step explanation:

The first step is to define the random variable x as:

x: number of oil explorations being succesful

Then x can be take this values:

x = 0 , x =1 ... x =10

x is a binomially distributed random variable with parameters.

p = 0.1 and  n=10

And the mean or the expected value of x is:

μ = E(x) = np

Then μ = 10*0.1 = 1

And the variance of x is:

V(x) = np(1-p)

V(x) = 10(0.1)(1-0.1)= 0.9
