Answer: 0.007
Step-by-step explanation:
Suppose that you have a ticket.
We have 3 prizes, and 300 tickets.
After the first tiket is drawn, someone win a prize, so now we have 299 tikets left and 2 prizes left.
Then, for the next draw, you have p = 1/299 of wining a prize.
If you did not win there, the probability for the third price is p = 1/298 (because there are 2 less tickets now)
Then the probability of winning at least one prize is:
P = 1/299 + 1/298 = 0.007
Answer:
Speed of plane in still air is 825 km/h
Step-by-step explanation:
Given:
Speed of plane with the wind is 145 km/h faster than what it would have with still air.
Speed of plane with wind = 970 km/h
To find speed of plane in still air.
Solution:
Let speed of plane in still air be =
So The speed of plane with wind would be given as =
Now Given:
Speed of plane with wind is given =970 km/h
So, we have:
Now Solving for "x" we get
Subtracting both sides by 145.
Hence, speed of plane in still air is 825 km/h
<h2>Greetings!</h2><h3>A way to do this is to divide the actual amount by the predicted amount:</h3>
8206 ÷ 13,426 = 0.6112
<h3>To change this back into a percentage simply multiply by 100:</h3>
0.6112 x 100 = 61.1
<h3>So the percent of voter turn out was 61.1%</h3><h2>Hope this helps!</h2>

x*.8=400
divide .8 from both sides
x=500
Answer:
see explanation
Step-by-step explanation:
(4)
arc XY is twice the inscribed angle YWX, thus
XY = 2 × 37° = 74°
The sum of the 3 arcs on the circle = 360°, thus
WY = 360° - (135 + 74)° = 360° - 209° = 151°
--------------------------------------------------------------------
(6)
arc QL = 2(3x + 23) = 6x + 46
QL + LK + KQ = 360, substitute values
6x + 46 + 9x - 6 + 140 = 360
15x + 180 = 360 ( subtract 180 from both sides )
15x = 180 ( divide both sides by 15 )
x = 12
