Given

See attachment for graph

Required

The rule of the graph

Pick any two points on the graph

$(x_1,y_1) = (0,0)$

$(x_2,y_2) = (1,4)$

Calculate slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{4 - 0}{1 - 0}$

$m = \frac{4}{1}$

$m =4$

The graph equation is:

$y = m(x - x_1) + y_1$

$y = 4(x - 0) + 0$

$y = 4(x)$

$y = 4x$

<em>The above shows that the x values are multiplied by 4 to get y</em>

True, all of them represent a negative number, for example:

You have $60 and you spent $10, the remaining money is:

$60-10=50$

Your savings are $1000 and you make a Withdrawal of $500:

$1000-500=500$

In other words for calculation purposes, they all have negative values

Use the binomial expression (p+q)n

zvonat [6]

Answer:

{0.16807, 0.36015, 0.3087, 0.1323, 0.02835, 0.00243}

Step-by-step explanation:

The expansion of (p+q)^n for n = 5 is ...

(p+q)^5 = p^5 +5·p^4·q +10·p^3·q^2 +10·p^2·q^3 +5·p·q^4 +q^5

When the probability p=0.3 and q = 1-p = 0.7 the terms of this series correspond to the probabilities of 5, 4, 3, 2, 1, and 0 favorable outcomes out of 5 trials.

For example, p^5 = 0.3^5 = 0.00243 is the probability of 5 favorable outcomes in 5 trials where the probability of each favorable outcome is 0.3.

___

The attachment shows the calculation of these numbers using a graphing calculator. It lists them in reverse order of the expansion of (p+q)^5 shown above, so that they are the probabilities of 0–5 favorable outcomes in the order 0–5.
