No If the coin was fair the 2 values should be closer together. The probability of a head ( and a tail) should be close to 1/2 for a fair coin.
x=10
Step-by-step explanation:
10 times -4 is -40 since if you multiply a negative number by a positive you get a negative
Answer:
Therefore, the first three term of the sequence is:
Hence, the sequence is:

Step-by-step explanation:
Given the nth term

The first three terms can be obtained by putting
and
respectively in the given nth term
Putting
to get the first term


Putting
to get the second term


Putting
to get the three term


Therefore, the first three term of the sequence is:
Hence, the sequence is:

Step-by-step explanation:
I don't know if it's correct
Area = 1/2 b * h
h = b - 9
b = b
Area = 56cm^2
Area = 1/2 (b - 9) * b
56 = 1/2 (b^2 -9b)
112 = b^2 - 9b
b^2 - 9b - 112 = 0
b = 16 and therefore the height is
h = 26 - 9 = 7
Check
Area = 1/2 * 16 * 7
Area = 8 *7
Area = 56 which checks.
