Can someone help me in probability?

1 answer:

8 0

The probability is a fraction. all possible outcomes / number of items
so 8/11 is the probablity of finding a number higher than 3 out of 11
could also be written as:
8/11
8:11
.73
73 percent

SOLUTION

The given equations are

$\begin{gathered} x+y=18 \\ y=x+12 \end{gathered}$

The graph of the equations are shown:

Notice that the line intersect at (3,15)

Therefore, the solutions of the system of equations are

$x=3,y=15$

Which of the following is true regarding the solution to the logarithmic equation below?

lidiya [134]

Answer:

Option C.

Step-by-step explanation:

Note: It is given question and option "=" sing is missing. On some places it should be "=" instead of "=".

Consider the given equation is

$\log_2(x+11)=4$

Using properties of \logarithm we get

$(x+11)=2^4$ $[\because \log_ax=b\Leftightarrow x=a^b]$

$x+11=16$

$x=16-11$

$x=5$

The solution is x=5.

To check the solution, substitute x=5 in the given equation.

$\log_2(5+11)=4$

$\log_2(16)=4$

$\log_22^4=4$

$4=4$

$LHS=RHS$

Therefore, x-5 is a true solution because $\log_2(16)=4$ .

Please help!! Due really soon!

Answer:

f(x) = 6x +1

Step-by-step explanation:

Differences in x-values (first row) are 1, 1, 1.

Differences in y-values (second row) are 6, 6, 6.

The constant ratio of differences (6/1) tells you the function is linear, and has a slope of m = 6/1 = 6.

Using the first point in the form ...

y = mx + b

we have ...

y = 6x + b

7 = 6·1 + b . . . . (x, y) = (1, 7)

1 = b . . . . . . subtract 6

Then the equation can be written ...

y = 6x +1

In functional form, this is ...

f(x) = 6x +1
