Serhud [2]3 years ago
4 0

Answer:

D

Step-by-step explanation:

The recursive formula allows us to find any term in a sequence by adding the common difference d to the previous term.

Here d = - 1 - (- 7) = - 1 + 7 = 6 , then

a_{n} = a_{n-1} + 6 ; a₁ = - 7

You have a 1 in 4 chance of winning a game. How would you calculate the probability that you will win 3 times in a row?
Ierofanga [76]

Answer:

<u>The probability of winning three games in a row is 1/64 or 1.6%</u>

Step-by-step explanation:

Probability of winning a game = 1/4

Probability of winning two games in a row = 1/4 * 1/4 = 1/16

Probability of winning three games in a row = 1/4 * 1/4 * 1/4 = 1/64

Probability of winning three games in a row = (1/4)³ = 1/64

1/64 = 0.015625

1/64 = 1.6% (rounding to the next tenth)

chubhunter [2.5K]

Answer:

Part A: B) 3

Part B: $40

4. -1

7. 5x + 6y

8. Part A: y = 20x

8. Part B: $300

9. e > 12000 pounds

Step-by-step explanation:

Part A: x = 5t + 5

20 = 5t +5

15 = 5t

t = 3

Part B: x = 5t + 5

x = 5(7) + 5

x = 35 +5

x = 40

4. 24 - 5^2

24 - (5*5)

24 - 25 = -1

7. 2x + 4y + 5 + 2y - 5 + 3x

2x + 3x = 5x

4y + 2y = 6y

5 + (-5) = 0

5x + 6y

8. Part A:

Total = y

Lawns = x

Amount = $20

so y = 20x

8. Part B:

y = 20x

y = 20(15)

y = 300

9. The elephant weighs more than 12000 pounds

Elephant = e

More than =  >

Pounds = 12000

e > 12000 pounds
