For this case we have that, by definition of power properties, the division of powers of the same base is given by:

\frac {a ^ m} {a ^ n} = a ^ {m-n}

So, if we have:

\frac {2 ^ {14}} {2 ^ 7}, the quotient is given by:

2 ^{14-7} = 2 ^ 7

Answer:

\frac {2 ^ {14}} {2 ^ 7} = 2 ^ 7

Option B

I can walk 2 miles in 1/3 of an hour. How long will it take me to get to the gas station that is 1/2 a mile away?
spin [16.1K]

Answer:

1/12 of an hour, or 5 minutes.

Step-by-step explanation:

Since ½ miles is ¼ of 2 miles, you would divide ⅓ by 4 to get 1/12 hours. That converted to minutes is 5 minutes.

Waitresses all want to work the "high roller" room at a local restaurant. There are six waitresses each evening assigned to one
Stells [14]

Answer:

The expected amount earned by a waitress per evening is $95.83.

Step-by-step explanation:

At a local restaurant there are six rooms total; 1 is a "high roller" room and other 5 are normal rooms.

There are 6 waitresses working at the local restaurant.

The room assignments are made by fair random selection such that each waitress has an equal probability of being in the "high roller" room.

This implies that a waitress can be assigned any of the six rooms with probability, \frac{1}{6}.

The tip earned by the waitress working in the "high roller" room is $200 and that for other rooms is $75.

So, the distribution of tips earned is as follows:

    X: $200    $75    $75    $75    $75    $75

P (X):     \frac{1}{6}          \frac{1}{6}         \frac{1}{6}          \frac{1}{6}         \frac{1}{6}         \frac{1}{6}

The expected value of a random variable is given by:

E(X)=\sum x\cdot P (X)

Compute the expected amount earned by a waitress per evening as follows:

E(X)=\sum x\cdot P (X)

         =(200\times \frac{1}{6})+(75\times \frac{5}{6})\\\\=\frac{575}{6}\\\\=95.8333\\\\\approx 95.83

Thus, the expected amount earned by a waitress per evening is $95.83.

Mumz [18]

Answer: $756

Step-by-step explanation:

convert feet to yards

1 yard = 3 feet

27 ft = 9 yards

18 ft = 6 yards

carpet represents area

area = length x width

area = 9 x 6

area = 54 yards^2

$14 for 54 yards^2 = 14 x 54

14 x 54 = 756

$756
