Answer:

7,13,31,85,247......

Step-by-step explanation:

$a_n =3^n + 4$

$\sf a_1=3^1 + 4 = 3 + 4 = 7\\\\a_2 = 3^2 + 4 = 9 + 4 = 13\\\\a_3 = 3^3 + 4 = 27 + 4 = 31\\\\a_4 = 3^4 + 4 = 81 + 4 = 85\\\\a_5 = 3^5 + 4 = 243 + 4 = 247$

Solve |2x - 6| > 10

inn [45]

ANSWER

{x|x < -2 or x > 8}

EXPLANATION

The given absolute inequality is

$|2x - 6| \: > \: 10$

By the definition of absolute value,

$(2x - 6)\: > \: 10 \: or \: \: - (2x - 6)\: > \: 10$

Multiply through the second inequality by -1 and reverse the inequality sign

$2x - 6\: > \: 10 \: or \: \: 2x - 6\: < \: - 10$

$2x \: > \: 10 + 6\: or \: \: 2x \: < \: - 10 + 6$

Simplify

$2x \: > \: 16\: or \: \: 2x \: < \: -4$

Divide through by 2

$x \: > \: 8\: or \: \: x \: < \: -2$

The time needed to complete a final examination in a particular college course is normallydistributed with a mean of 80 minutes

Artist 52 [7]

Answer:

a) 0.023

b) 0.286

c) 10 students will be unable to complete the exam inthe allotted time.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 80 minutes

Standard Deviation, σ = 10 minutes

We are given that the distribution of time to complete an exam is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(completing the exam in one hour or less)

P(x < 60)

$P( x < 60) = P( z < \displaystyle\frac{60 - 80}{10}) = P(z < -2)$

Calculation the value from standard normal z table, we have,

$P(x < 60) =0.023= 2.3\%$

b) P(complete the exam in more than 60 minutes but less than 75 minutes)

$P(60 \leq x \leq 75) = P(\displaystyle\frac{60 - 80}{10} \leq z \leq \displaystyle\frac{75-80}{10}) = P(-2 \leq z \leq -0.5)\\\\= P(z \leq -0.5) - P(z < -2)\\= 0.309- 0.023 = 0.286= 28.6\%$
