Answer:
$20
Step-by-step explanation:
10% = 10/100 = 0.1
So 10% of 200 = 200 x 0.1 = 20
We will be using the fact that
, where
is the probability that the first bulb works and
is the probability that the second bulb works.
The probability that the first bulb works is
. However, when we take one out (given that the first bulb works) we now have 19 working bulbs and 4 bad ones. This means that the probability that the second bulb works is
.
Now, we can find our final probability:

Answer:
x = 7°
<GDH = 112°
<FDH = 192°
<FDE = 135°
Step-by-step explanation:
If DE bisects <GDH this means that <GDE = <EDH
Given <GDE = (8x+1)° and <EDH = (6x+15)° then;
8x+1 = 6x+15
8x-6x = 15-1
2x = 14
x = 7°
Since <GDH = <GDE + <EDH
<GDH = 8x-1+6x+15
<GDH = 14x+14
<GDH = 14(7)+14
<GDH = 98+14
<GDH = 112°
For <FDH,
Note that sum of angle on a straight line is 180°
<FDH = <FDG + <GDE + <EDH
<FDH = <FDG + <GDH
<FDG = 180-(43+8x+1)
<FDG = 180-44-8x = 136-8x
<FDH = 136-8x+112
<FDH = 248-8x
<FDH = 248-8(7)
<FDH = 248-56
<FDH = 192°
For <FDE;
<FDE = <FDG + <GDE
<FDE = 136-8x+8x-1
<FDE = 135°
I saw the pie chart that should have accompanied this word problem.
Favorite fruit:
Grapes = 150
Apple = 220
Orange = 185
Banana = 235
Choices:
A) 37/47
B) 185/790
C) 790/275
D) 235/185
Oranges = 185 ; Bananas = 235
Ratio of oranges to Bananas = 185/235
Simplify 185/235
185 ÷ 5 = 37
235 ÷ 5 = 47
Ratio of oranges to Bananas = 37/47 Choice A.
