WILL MARK BRAINLIST!! Olivia rolls two fair number cubes numbered from 1 to 6. She first defines the sample space as shown below

ArbitrLikvidat [17]

The probability of getting a total of 10 will be $\frac{1}{12}$

<em><u>Explanation</u></em>

The total possible sample spaces for rolling two fair numbered cubes are :

(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6) (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6) (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6) (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6) (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6) (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)

There are total 36 sample spaces.

We need to get a sum of 10 , so the possible sample spaces will be:

(4, 6) , (5, 5) and (6, 4)

That means there are 3 possible sample spaces for getting a sum of 10.

So, the probability of getting a total of 10 $= \frac{3}{36} = \frac{1}{12}$

The number of leaves that fall off a tree n days after day 1 is given by the function f (n) = 3(2)".

densk [106]

Answer:

A. On the first day, 3 leaves fall.

B. D. The number of leaves that fall on a given day is 2 times the number of leaves that fell on the previous day.

Step-by-step explanation:

Given

$f(n) = 3(2)^n$

Solving (a) The meaning of 3.

3 represents the initial number of leaves (i.e. the first day) and this proved as follows.

On the first day, n = 0.

Substitute 0 for n in $f(n) = 3(2)^n$

$f(0) = 3(2)^0$

$f(0) = 3*1$

$f(0) = 3$

Solving (b) The meaning of 2.

2 represents the rate which leaves fall down.

In (a)

$f(0) = 3$

Take n = 1

Substitute 1 for n in $f(n) = 3(2)^n$

$f(1) = 3(2)^1$

$f(1) = 3*2$

$f(1) = 6$

When f(1) is divided by f(0), the result 2. So, the number of leaves doubles everyday

When you graph an inequality, you used a closed dot when you use which<br> symbols?

aksik [14]

You use a closed dot with the greater than or less than with the line under the symbol or the greater than or equal to or the less than or equal to symbols. The line indicates a closed dot.
