A balanced coin will have 50:50 chance of showing either head or tail. In this question, you are asked the probability to find the first head after two tosses. That means the toss result should be:
1. tail = 1/2 probability
2. head = 1/2 probability
Previously you are tossing the coin 10 times and obtain zero head. But this previous 10 tosses result should not influence your probability in the 11th and 12th toss. The chance will always be 50:50 no matter how much the tosses count. So the probability should be: 1/2 * 1/2= 1/4
P=26=2*(l+L)
⇒ l+L=26:2=13 feet
l=3, L=10
A=l*L=30=10*3
⇒ l=3 feet
L=10 feet
4x = y
2x^2 - y = 0
2x^2 - 4x = 0
2x(x - 2) = 0
2x = 0 or x - 2 = 0
x = 0 or x = 2
y = 4(0) or y = 4(2)
y = 0 or y = 8
Therefore, solution set is {(0, 0), (2, 8)}
Answer:
2/6 = 48/144
7/8 = 168/192
Step-by-step explanation:
Use the least common denominator to write an equivalent fraction for each fraction. 2/6 , 7/8 The least common denominator is 24 .
2/6 can be rewritten as __
We Multiply both numerator and Denominator by 24
48/144
7/8 can be rewritten as __
We Multiply both numerator and Denominator by 24
168/192
Answer:
15.6km
Step-by-step explanation:
Given the map scale 1:200000
1cm on the map represents 200000 cm on ground or in actual distance
Hence, if distance from Belfast to Larne is 7.8vm on map ;
Actual distance will be :
7.8 * 200000 = 1560000 cm
Converting to km :
Recall :
1000 m = 1km
100 cm = 1 m
Hence,
100000 cm = 1km
Therefore, (1560000 / 100000) km
= 15.6km
Hence, distance between Belfast and Larne is 15.6km
