The first term in a sequence of numbers is 1/2

Mathematics
1 answer:
Andrei [34K]3 years ago
7 0

Answer:

The correct answer is C. The 4th term is 11.

Step-by-step explanation:

Since the next term is one more than twice the previous, we can calculate it by the following expression:

a_{n} = 2*a_{n-1} + 1

So the second term is:

a_2 = 2*\frac{1}{2} + 1\\a_2 = 2

The third term:

a_3 = 2*2 + 1\\a_3 = 5

And the fourth term:

a_4 = 2*5 + 1\\a_4 = 10 + 1 = 11

The correct answer is C. The 4th term is 11.

3p+2h=195

p + 15 = h

3p + 2(p + 15) = 195

3p + 2p + 30 = 195

5p = 165 (combine like terms and isolate your variable)

p = 33

33 + 15 = 48 (plug 33 into your original second equation)

ANSWER: 33 pretzels and 48 hotdogs
**You can plug these into your original (first) equation to check your answer

The probability of picking a black ball first is \dfrac{4}{5}, because there are 4 black balls and 1 white ball which is 5 balls in total. After picking the first ball, 4 balls remain - 3 black and 1 white, so the probability of picking a white ball is \dfrac{1}{4}.
So, the probability of picking a black ball first followed by a white ball is \dfrac{4}{5}\cdot\dfrac{1}{4}=\dfrac{1}{5}
