A container is being filled with water at a steady rate. The graph shows how the volume of water in the container varies with th

Mkey [24]

Answer: a. $v=\dfrac{2}{3}t$ and b. $t=\dfrac{3}{2}v$ .

Step-by-step explanation:

Let as consider,

Volume (in gallons) of water in the container = v

The number of minutes = t

(a)

From the given graph it is clear that the line passing through the points (0,0) and (3,2). So, the equation of line is

$v-v_1=\dfrac{v_2-v_1}{t_2-t_1}(t-t_1)$

$v-0=\dfrac{2-0}{3-0}(t-0)$

$v=\dfrac{2}{3}t$

Therefore, the required formula is $v=\dfrac{2}{3}t$ .

(b)

We have,

$v=\dfrac{2}{3}t$

Multiply both sides by 3/2.

$v\times \dfrac{3}{2}=\dfrac{2}{3}t\times \dfrac{3}{2}$

$\dfrac{3}{2}v=t$

$t=\dfrac{3}{2}v$

Therefore, the required formula is $t=\dfrac{3}{2}v$ .

Triss [41]

Answer:

0.82 = 82% probability that at least one party will not order drinks

Step-by-step explanation:

For each party, there are only two possible outcomes. Either they will order drinks with their meal, or they will not. The probability of a party ordering drinks with their meal is independent of other parties. So the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

When Ryan is serving at a restaurant, there is a 0.75 probability that each party will order drinks with their meal.

This means that $p = 0.75$

During one hour, Ryan served 6 parties. Assuming that each party is equally likely to order drinks, what is the probability that at least one party will not order drinks?

6 parties, so n = 6.

Either all parties will order drinks, or at least one will not. The sum of the probabilities of these events is decimal 1. So

$P(X = 6) + P(X < 6) = 1$

We want P(X < 6). So

$P(X < 6) = 1 - P(X = 6)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 6) = C_{6,6}.(0.75)^{6}.(0.25)^{0} = 0.18$

$P(X < 6) = 1 - P(X = 6) = 1 - 0.18 = 0.82$

0.82 = 82% probability that at least one party will not order drinks
