Answer:

4th term = 29

to generate the terms, substitute n = 2, 3, 4 into the rule

noting that b(1) = - 7

b(2) = b(2 - 1) + 12 = b(1) + 12 = -7 + 12 = 5

b(3) = b(3 - 1) + 12 = b(2) + 12 = 5 + 12 = 17

b(4) = b(4 - 1) + 12 = b(3) + 12 = 17 + 12 = 29

When Lin drives a golf ball, it travels a mean distance of 200 yards with a standard deviation of 20 yards, and the distribution

Anettt [7]

Answer:

The percentage of her shots that will travel less than 180 yards is approximately 15.9%

Step-by-step explanation:

First it will be required to find the standard or z-score from the following formula

$z = \frac{x- \mu}{\sigma}$

Where:

z = z or standard score

x = value that is observed = 180 yards

μ = Sample mean = 200 yards

σ = Sample standard deviation yards

Plugging the values, we have;

$z = \frac{180- 200}{20} = -1$

Therefore, the probability that her shots will travel less than 180 is given by the relation;

p( x < 180 yards) = p(z < -1) = 0.15866

Therefore, the percentage of her shots that will travel less than 180 = 0.15866 × 100

= 15.866% ≈ 15.9%.

You deposit $8500 in an account that pays 1.78% annual interest. Find the balance after 10 years when the interest is compounded

Feliz [49]

Step-by-step explanation:

step 1. let's call the balance A, the initial amount P, the yearly rate r, the number of compounds yearly n, and the time t.

step 2. A = P(1 + r/n)^(nt) (compounding equation)

step 3. A = 8500(1 + .0178/12)^((12)(10))

step 4. A = 8500(1.00148334)^120

step 5. A = $10,154.68.
