Answer:

g(5) = 5

Step-by-step explanation:

g(5) is really g when x=5 so we have to use the function g(x) when x≥2

g(5) = 2x-5 when x=5

g(5) = 2*5 -5 = 10-5 = 5

Answer:

$P(x < 3) = 25\%$

$E(x) = 3$

Step-by-step explanation:

The given parameters can be represented as:

$\begin{array}{ccccccc}x & {5} & {4} & {3} & {2} & {1}& {0} & P(x) & {25\%} & {30\%} & {20\%} & {15\%} & {5\%} & {5\%} \ \end{array}$

Solving (a): P(x < 3)

This is calculated as:

$P(x < 3) = P(x = 0) + P(x = 1) + P(x =2)$ ----- i.e. all probabilities less than 3

So, we have:

$P(x < 3) = 5\% + 5\% + 15\%$

$P(x < 3) = 25\%$

Solving (b): Expected number of events

This is calculated as:

$E(x) = \sum x * P(x)$

So, we have:

$E(x) = 5 * 25\% + 4 * 30\% + 3 * 20\% + 2 * 15\% + 1 * 5\% + 0 * 5\%$

$E(x) = 125\% + 120\% + 60\% + 30\% + 5\% + 0\%$

$E(x) = 340\%$

Express as decimal

$E(x) = 3.40$

Approximate to the nearest integer

$E(x) = 3$

Which equation represents a line with a slope of 4 that passes through the point (1, 3)?

alina1380 [7]

Answer:

y = 4x - 1

Step-by-step explanation:

The line has a slope of 4.

And passes through the point (1,3)

Taking another point (x,y) on the line;

$\frac{y - 3}{x - 1}$ = 4

y - 3 = 4x - 4

y = 4x - 4 + 3

y = 4x - 1

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Leviafan [203]

Answer: $\bold{(A)\ a_n=500,000(1.1)^{n-1}}$

<u>Step-by-step explanation:</u>

From the data provided, we know the sequence is {500,000; 550,000; 605,000; ... }. $So, a_1 = 500,000\ and\ r = \dfrac{550,000}{500,000}=1.1$

The explicit rule for a geometric sequence is: $a_n=a_1(r)^{n-1}$

So, the explicit rule for the sequence above is: $a_n=500,000(1.1)^{n-1}$
