Answer:

X = {8n – 7n – 1 : n ϵ N}

Y = {49 (n –1) : n ϵ N} — (1) [all terms divisible by 49]

X = {8n – 7n – 1}

= (1 + 7)n – 7n – 1

= 1 + nC1 7 + nC2 72 + ….. + nCn 7n – 7n – 1

= nC2 72 + …… + nCn 7n

= 49 [nC2 + nC3 7 + …. nCn 7n-2] — (2)

From (1) and (2),

X is divisible by 49.

Y has all multiples of 49.

X ⊂ Y

A local pizza restaurant delivery time has a uniform distribution over 0 to 60 minutes. What is the probability that the pizza d

Likurg_2 [28]

Answer:

$X \sim Unif (a= 0, b=60)$

And we want to find the following probability:

$P(X>30)$

And for this case we can use the cumulative distribution given by:

$F(x) =\frac{x-a}{b-a}, a \leq x \leq b$

And for this case if we use this formula and the complement rule we have:

$P(X>30)= 1-P(X$

Step-by-step explanation:

Let X the random variable who represent the pizza delivery time and we know that the distribution for x is given by:

$X \sim Unif (a= 0, b=60)$

And we want to find the following probability:

$P(X>30)$

And for this case we can use the cumulative distribution given by:

$F(x) =\frac{x-a}{b-a}, a \leq x \leq b$

And for this case if we use this formula and the complement rule we have:

$P(X>30)= 1-P(X$
