There are four (4) colors to choose from. The number of sample space is equal to 4. With the condition given in this item, the probability of landing on blue on the first spin is equal to 1/4. Similarly, the probability of landing on yellow on the second spin is 1/4.
P = (1/4)(1/4)
P = 1/16
Answer: 1/16
2:4 is the probability. It is more likely to receive a ordinary quarter, but the probability of the two headed quarter is still great enough to get it.
Answer:
b=4.9
C. is the correct option.
Step-by-step explanation:
In triangle TGN,
Let <RTG be x
cosx= b/h
or, cosx = 2/a
Again,
In triangle TRG,
cosx = b/h
(for bigger right angled triangle)
cosx = a/(4+2)
cosx = a/6
Now
cosx = 2/a = a/6
or, 2/a = a/6
or, 12 = a²
so, a² = 12
Now,
For TRG,
h² = p²+b²
or, 6² = b² + a²(a²=12)
or, 6² = b² + 12
or, 36 = b² + 12
or, 36 -12 = b²
or, b² = 24
or, b = square root 24
so, b = 4.8989
so, b = 4.9
Answer:
Vectors are not the same as lengths.
Step-by-step explanation:
1. The error is that Vector AB + Vector BC = Vector AC
2. The same thing relates to the second analyses(Vector AD is equal Vector DC)
3. The third is all right.
