Answer:
Step-by-step explanation:
There are 20 ballots, 8 have drawn a car the rest are white.
Find the probability to extract at least one ballot with the drawing of a car if not replaced:
1. If a ballot is taken out:
8 have drawn a car: thus we have 8/20 = 2/5
2. If two ballots are removed, probability of extracting 1 ballot with drawing of car is 8/20 leaving 7 out of 19 remaining. The 7/19 is the probability of drawing out a second ballot with the drawing of a car. Thus we have
8/20 * 7/19 = 56/380 = 14/95
3. If three ballots are removed, probability of extracting 1 ballot with drawing of car is 8/20 leaving 7 out of 19 remaining. The 7/19 is the probability of drawing out a second ballot with the drawing of a car leaving 6 out of 18 remaining. The 6/18 is the probability of drawing out a third ballot with the drawing of a car.
8/20 * 7/19 * 6/18 = 42/855
Answer:
Step-by-step explanation:
The shape above is a composite shape having two different shapes like rectangle and semi- circle
Area of rectangle=Length × Breadth
Area of semi circle=1/2πr^2
To find the area of the rectangle naw
Length of the rectangle=6.6
Width of the rectangle=4
A=6.6×4
A=26cm^2
Area of semi-circle=1/2
Diameter of the shape =4cm
Radius=2cm
A=1/2×3.14×2cm x2cm
A=6.28cm^2
Area of the shape=26+6.28cm^2
Area=32.28 to 2 dp

The formula used to convert Fahrenheit in to Celsius is:
Step-by-step explanation:
Here, the given expression is :
The above expression converts Celsius in to Fahrenheit.
Now we need an expression to convert Fahrenheit in to Celsius.
Simplifying the above for the value of C, we get:
Hence, the formula used to convert Fahrenheit in to Celsius is:
