A spinner has 3 red spaces, 5 white spaces, and 1 black space. If the spinner is
Pie

Answer:

\frac{2}{3}

Step-by-step explanation:

If we have 3 red spaces, 5 white spaces, and one blank space, there are a total of 9 spaces.

Since there are 3 red spaces, there is a \frac{3}{9} = \frac{1}{3} chance of getting a red. However, the question asks the probability of not getting a red, so the chances of not getting a red are 1 -\frac{1}{3} = \frac{2}{3}.

Hope this helped!

Anyone know what the answer is???(sorry if it’s unclear)
Sergio [31]

The laws of exponents I will be using are:

(x^y)^z = x^{yz}, and x^y \cdot x^z = x^{y+z}.

For the first part, (15^3)^3 \cdot 15^{-6} = 15^9 \cdot 15^{-6} = 15^3.

For the second part, 15 \cdot (15^3)^2 \cdot (15^{-5})^2 = 15 \cdot (15^6) \cdot (15^{-10}) = 15^{1+6-10} = 15^{-3} = \frac{1}{15^3}.

Which of the following is an extraneous solution of mc015-1.jpg? x = –12 x = –3 x = 3 x = 12
kramer
The answer
the full the question is as follow:
<span>Which of the following is an extraneous solution of (45 - 3x)^1/2 =x -9

for solving such an equation, this is the method:

finding the squared value of each member of the equation
</span>[(45 - 3x)^1/2 ]²  = (x -9)²   (E)
<span>
extend each value of the member
</span>[(45 - 3x)^1/2 ]² = 45 - 3x, because   (sqrt a )² = a
the condition is 45 - 3x≥0 ( because of the square root)
it means  - 3x≥ -45 and  x ≤ 15

(x -9)² = x²-18x + 81
<span>
so </span>45 - 3x = x²-18x + 81, this is equivalent to x² - 15x  +36 =0
<span>
this equation should solve for x, for finding the help

Delta = 15² - 4*36 = 81, so x = - (-15) - sqrt (81)  /  2 *1=15-9 /2= 3

                                      and </span>x = - (-15) +sqrt (81)  /  2 *1= 15 +9/2= 24/2=12
<span>
for x= 12, the equation given above ( equation E) has no solution, because 
we can find 3=9

so </span><span>an extraneous solution is x = 12</span><span>

</span>
