Harvey conducted a probability experiment using a cube numbered 1-6 and a spinner with three equal spaces, as shown.

svet-max [94.6K]

Answer:

We have two independent events.

A number cube, with 6 possible outcomes.

A spinner, with 3 possible outcomes.

Each element in the combined sample space will be something like:

(outcome of the number cube, outcome of the spinner).

Then the number of possible outcomes in the sample size is equal to the product between the number of outcomes in each event.

Sample space size = 6*3 = 18.

What is the solution to . (3x10^2)x(5x10^5) written in scientific notation .

klasskru [66]

The scientific notation:

$a\cdot10^k,\ 1\leq a < 10,\ k\in\mathbb{Z}$

$(3\cdot10^2)(5\cdot10^5)=[(3)(5)][(10^2)(10^5)]=15\cdot10^{2+5}=15\cdot10^7\\\\=1.5\cdot10\cdot10^7=1.5\cdot10^8\\\\Answer:\ (3\cdot10^2)(5\cdot10^5)=1.5\cdot10^8\\\\Used\ a^n\cdot a^m=a^{n+m}$

"if the standard deviation of a group of 20 scores is 15, what is the variance?"

DerKrebs [107]

We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.

Since we know variance is square of standard deviation. In order to find out the variance of the given data we have to take the square of 15.

$\text{ Variance}=\sigma^{2}\\
=15^{2}=225$

Therefore, our variance is 225.
