Answer:
The chance of losing five games in a row is 0.8 × 0.8 × 0.8 × 0.8 × 0.8 = 0.85 = 0.328. The chances of that not happening is 0.672. That’s the chance that you will win at least one game out of the five. 67.2%.
Much later:
I just noticed that this question had details that are now in a comment:
I already know the technique: 1 - (0.8)^5
But I wanted to know how to do it in other ways
Sadly Quora no longer shows the question details below the question the way it used to. My answer explained it in the way the asker indicated in their comment that they already knew and they wanted something different. Sorry about that. At this point, I’m not inclined to try figuring out other ways (enumerating all the sequences, for example, and tallying the probabilities).
Step-by-step explanation:
I think the inequality is 55,000>=40x+5,000 while x<=1,250 i have the same test
Hmm i think its this 55,000 >= 40x+5,000 because it needs atleast 55,000
Which explains 55,000>= second receives 55 per race but spend 15 race in other terms 55x-15x= 40 x
So 55,000>=40x third 10,000 in donations sponsers a 5,000 race 10,000-5,000=5,000 so 55,000>=40x+5,000
Also to find x 55,000>=40x+5,000 subtract 5,000
50,000>=40x now divide by 40
50,000/40>=x
X<= 1,250
Answer:
option B
Step-by-step explanation:
we know:
area of a rectangle= b*h
in this case we have from the picture:
b=4
h=6
so we have:
area of a rectangle= 4*6
area of a rectangle= 24 square units
All sides and angles are congruent
Answer:
<em>0.253 m/s</em>
<em></em>
Step-by-step explanation:
radius r of the circular rise = 13 mm = 0.013 m
apparent weight loss = 50%
acceleration of the new weight = 0.5 x 9.81 = 4.905 m/s^2
centripetal acceleration = 9.81 - 4.905 = 4.905 m/s^2
centripetal acceleration =
where v is the acceleration at the rise and r is the radius of the rise
centripetal force = =
4.905 =
= 0.063765
v = = <em>0.253 m/s</em>
