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:

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

Answer:

Answers are: 2x - 7, and 2x -7 = 14

Step-by-step explanation:

An expression must have variables must have a coefficient, a number that is multiplied divided added or subtracted by our variable. The variable is a place holder.

So our answers would be 2x - 7, and 2x -7 = 14

If x and y vary inversely, then xy = const.

x = 10, y = 8

$xy=10\cdot8\\\\xy=80\ \ \ \ |:x\\\\\boxed{y=\dfrac{80}{x}}$
