A rectangle has the following vertices. Find the area of the rectangle (-8,-6), (4, -6), (1,2), (8,2)
Tju [1.3M]
Answer: 84

Steps:

1. Find distance between (-8,-6) and (4,-6) using distance formula:

√ (4 - (-8))^2 + ((-6) - (-6))^2
√ (12)^2 + (0)^2
√ 144 + 0
√ 144
12

2. Find distance between (1,2) and (8,2) using distance formula:

√ (8-1)^2 + (2-2)^2
√ (7)^2 + (0)^2
√ 49 + 0
√ 49
7

3. Multiply found values to find area

A = l x w
A = 12 x 7
A = 84

If the wait time is less than 30 minutes for 75% of all patients in the emergency room, what is the probability that the
Greeley [361]

The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less is 0.0020

<h3>What is probability? </h3>

Probability can be defined as the likelihood of an event to occur. In statistics, the mean of the sample distribution typically shows the probability of the population.

From the parameters given:

  • The sample size (n) = 55 patients
  • Let's assume that the mean (x) = 32 (i.e. 58.2%) of the patients

The sample proportion \mathbf{\hat p} can be computed by using the expression:

\mathbf{\hat p = \dfrac{x}{n}}

\mathbf{\hat p = \dfrac{32}{55}}

\mathbf{\hat p =0.582}

If the percentage of the probability of all patients in the emergency room = 0.75

The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less can be computed as:

\mathbf{( \hat P \leq 0.582) = P \Big( \dfrac{\hat p - p}{\sqrt{\dfrac{p(1-p)}{n}}} \leq \dfrac{0.582 - 0.75}{\sqrt{\dfrac{0.75(1-0.75)}{55}}} \Big )}

\mathbf{( \hat P \leq 0.582 )= P \Big( Z \leq \dfrac{-0.168}{\sqrt{0.003409}} \Big )}

\mathbf{( \hat P \leq 0.582) = P \Big( Z \leq -2.88 \Big )}

From the Z distribution table:

\mathbf{( \hat P \leq 0.582) = 0.00198}

\mathbf{( \hat P \leq 0.582) \simeq 0.0020}
