Answer:

9/35

Step-by-step explanation:

There are a total of 15 bulbs to choose from randomly. First a new bulb is chosen. Chance is 9/15 because 9 out of 15 are new.

Then there are only 14 bulbs left. Then a used bulb is chosen. Chance is 6/14 since 6 out of remaining 14 are used.

Total chance for this to happen is 9/15 * 6/14 = 54/210 = 9/35.

THow much will fencing cost to enclose a field that is 725 feet by 1,021 feet if fencing costs $13.57 per foot? $47,386.44 $23,6
iogann1982 [59]

Answer:

$47,386.44

Step-by-step explanation:

Given;

Dimension of the field = 725 feet by 1,021 feet

Length = 1021 ft

Breadth = 725 ft

Cost per foot = $13.57 per foot

Perimeter of the field = 2 × (length + breadth)

Perimeter = 2 × ( 1021 + 725) = 3492 ft

The cost of fencing the field is;

Cost per feet × perimeter

= $13.57 × 3492

= $47,386.44

statuscvo [17]

Answer:

\dfrac{14}{75}

Step-by-step explanation:

Gavin made 6 out of 15 shots, so the probability that Gavin's next shot will be  successful is

\dfrac{6}{15}=\dfrac{2}{5}

Jack made 7 out of 15 shots, so the probability that Jack's next shot will be  successful is

\dfrac{7}{15}

The probability that they both make their next shot successfully is

\dfrac{2}{5}\cdot \dfrac{7}{15}=\dfrac{14}{75}
