Answer:

See below

Step-by-step explanation:

5^{-3} - When you are raising a number to a negative power, it is the same as dividing 1 by that power when it is positive. So, 5^{-3} can be written as: \frac{1}{5^{3}}.

5^3 is 125, so we can substitute that in to get: \frac{1}{125}

-5^{-3} - This expression is the same as the one before, but it is negative. This means we can say -5^{-3} = -\frac{1}{125}

(-5^{-3})^{-1} - We can start by writing -5^{-3} as -1 * 5^{-3}. Now, we can distribute the exponent -1, and simplify. Remember when raising a power in parenthesis to another power, you multiply them:

(-1 * 5^{-3})^{-1}\\(-1)^{-1} * (5^{-3})^{-1}\\-1*5^3\\-1*125\\-125

(-5^{-3})^0 - We can start by writing -5^{-3} as -1 * 5^{-3}. Now, we can distribute the exponent 0, and simplify:

(-1*5^{-3})^0\\(-1)^0 * (5^{-3})^0\\1 * 1\\1

Answer:

1/125, -1/125, -125, 1

Step-by-step explanation:

1. 5^-3 = 1/5^3 = 1/125

2. -5^-3 = 1/-5^3 = -1/125

3. Take the answer above, its the first part of the question; (-1/125)^-1 = -125

4. Any real number raised to the 0th power is one.

andriy [413]

Answer:

P=0.54.

Step-by-step explanation:

We know that in a sample of 6500 automobiles found that 1560 of the automobiles were black, 3120 of the automobiles were sedans, and 1170 of the automobiles were black sedans.

We calculate the number of  sedans that are not black:

3120-1170=1950

We calculate the number of black cars  that are not sedans:

1560-1170=390

The number of automobiles  which are black or a sedan is

1950+390+1170=3510.

The probability that  the automobile is black or a sedan is:

P=3510/6500

P=0.54.
