dybincka [34]

Answer:

\frac{1}{2}

Step-by-step explanation:

In this graph, when you count rise and run, rise would be 1 and run would be 2. Because slope is also known as rate of change and rate of change is also known as rise over run, the slope will be 1 over 2.

If you roll two number cubes, what is the probability of their sum being 9 or higher?
aalyn [17]

Answer:

Pe = \frac{10}{36}

Step-by-step explanation:

Well, a standard cube number (dice) has numbers from 1 to 6. So the combinations that give 9 or higher, are 3-6, 6-3, 4-5, 5-4, 4-6, 6-4,5-6, 6-5, 5-5, 6-6. We will call this favorable cases (Fc) = 10

Yet, the total number of cases (T) is 6 different number by 6 different combinations (1-1 , 1-2 , 1-3 ..... 6-6), 6 x 6= 36 = T.

So, in order to calculate the probability of an event (10/36), you can use the following formula:

Pe = \frac{Fc}{T}

Pe = \frac{10}{36} = 0.2777

Consider f(x) = bWhich statement(s) are true for 0 < b < 1? Check all that apply.
Ira Lisetskai [31]

Answer:

The domain is all real numbers.

The function is always decreasing

Step-by-step explanation:

Assuming the given function is

f(x) =  {b}^{x}

for

0 \:  <  \: b \:  <  \: 1

Then f(x) is an exponential decay function.

This means that, the domain will be all real numbers.

The range will be y<0

The y-intercept is (0,-1)

There is no x-intercept.

The graph is a decreasing function.

Find the mean of 12, 25, 36.
12 + 25 + 36 = 73
73 / 3 = 24.33
Our mean is 24.33.
