5 0

Answer:

0.295

Explanation:

Given that:

Total number of modems = 19

Number of defective modem = 3

Non-defective modems = 19 - 3 = 16

Probability of that all selected modems are not defective :

Required outcome / Total possible outcomes

[(16C6) * (3C0)] ÷ 19C6

(8008 * 1) ÷ 27132

8008 / 27132

= 0.2951

Hence,

Probability of accepting the shipment is 0.295

An airplane starts at 0 feet. It rose 21,000 feet at takeoff. it then descended 4,329 feet because of clouds. An oncoming plane

sveta [45]

answer

1). Airplane is flying at 14551 feet.

2). Height of the mountain is 4299 feet.

--------------------------------------------------------------------------------------------------------------

1). An airplane starts at the level = 0 feet

It rose to the altitude = 21000 feet

It descends by the height due to clouds = 4329 feet

So the height of the airplane = 21000 - 4329

= 16671 feet

After giving pass to a plane it ascends by the height = 6333 feet

Now the height of the airplane = 16671 + 6333

= 23004 feet

Then the airplane descends again to give the pass to a airplane again.

Altitude after descending by 8453 feet = 23004 - 8453 = 14551 feet

Airplane is flying at 14551 feet.

2). Distance between the top of the mountain to the floor of the valley = 4392 feet

Valley is 93 feet below the sea level.

Therefore, the height of the mountain will be = 4392 - 93

= 4299 feet

Use a Pythagorean Triple to find x.

dlinn [17]

Explanation:

Given

perpendicular (p) = 48

base(b) = 14

hypotenuse (h) = x = ?

We know by using Pythagoras theorem

x² = p² + b²

x² = 48² + 14²

x² =2304 + 196

x² = 2500

x = √2500

Therefore x = 50

Hope it will help you :)

John bought 15 pines for $3500

Shalnov [3]

Answer:

Explanation:

If John needs to ensure a 40% profit, John needs to sell the pines at a price that would give 40% more money back than he spent.

Since John needs to make back all of the money he spent, plus another 40%, John needs to get back 140% of what he spent.

$140\% = 1.40$

John spent $3500.

140% of $3500 is $4900.

So, John must bring in $4900 (revenue) selling all 15 pines to achieve a 40% profit.

However, the question asks for the price of a single pine. To find the unit price of a single pine, divide the total revenue by 15.

$\frac{\$4900}{15pines}=\frac{\$326.\bar{6}}{pine}=\$326.66 \text{ per pine}$
