Answer:
The fourth term of the sequence B(4) =-8
The sequence is 1,-2,4,-8...
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the sequence
B(n) = 1(-2)ⁿ⁻¹
Put n=1
B(1) = 1(-2)¹⁻¹ = 2⁰ =1
Put n=2
B(2) = 1(-2)²⁻¹ = (-2)¹ =-2
Put n=3
B(3) =1(-2)³⁻¹ = (-2)² =4
Put n=4
B(4) = 1(-2)⁴⁻¹ =(-2)³ =-8
The sequence
1,-2,4,-8...
24q-8=11 (use distributive property)
24q= 11+8
24q = 20
q= 20/24
q= 0.8
Answer:
Experimental probability is likely to be slightly different from theoretical probability.
Step-by-step explanation:
This is because there is a 50-50 chance, but it is unlikely to be exactly 100-100. That is just to hypothesis!
Answer: 9 years
Step-by-step explanation:
Let the present age of Ashley be x.
Then the present age of Alfonso =x+8
Five years ago,
Ashley's age = x-5
Alfonso's age = x+8-5 = x+3
According to the question,
Hence, the present age of Ashley =9 years
