Answer:

1) 0.1504

2) 0.432

Step-by-step explanation:

1) The given information are;

The proportion of the morning appointments that are with elderly patients = 60%

The number of patients in the appointments  = 10 patients

The proportion of the morning appointments that are with non-elderly patients = 100 - 60 = 40%

The binomial probability distribution is given as follows;

P(X = r) = \dbinom{n}{r}p^{r}\left (1-p  \right )^{n-r}

P(X = 0) = \dbinom{10}{0}0.6^{0}\left (1-0.6  \right )^{10} = 0.000105

P(X = 1) = \dbinom{10}{1}0.6^{1}\left (1-0.6  \right )^{9} = 0.0016

P(X = 2) = \dbinom{10}{2}0.6^{2}\left (1-0.6  \right )^{8}= 0.01062

P(X = 3) = \dbinom{10}{3}0.6^{3}\left (1-0.6  \right )^{7}= 0.0425

The probability that the first four patients are elderly is 0.000105 + 0.0016 + 0.1062 + 0.0425 = 0.1504

2) The probability that exactly 2 out of 3 morning patients are elderly patient is given as follows

P(X = 2) = \dbinom{3}{2}0.6^{2}\left (1-0.6  \right )^{1}= 0.432

Answer:

  • 10.235 in²
  • 225 cm²

Step-by-step explanation:

The area of a triangle is half the product of its base and height.

  A = 1/2bh

<h3>a)</h3>

  A = 1/2(2.3 in)(8.9 in) = 10.235 in²

__

<h3>b)</h3>

  A = 1/2(15 cm)(30 cm) = 225 cm²

Investment: Suppose you receive a gift of $1,000 and decide to open a CD (certificate of
Nina [5.8K]

Answer: 4 years after the original investment, it is approximately $1,093.

Step-by-step explanation:

Hi, to answer this question we have to apply the simple interest formula:  

I = p x r x t

Where:  

I = interest

P = Principal Amount  

r = Interest Rate (decimal form)  

t= years

Replacing with the values given  

I = 1000x (2.25/100) x t

  • It will triple in approximately 3 years. FALSE

I = 1000x (2.25/100) x 3 =67.5

1000+67.5 = 1067.5

  • It will no longer grow after several years: False, it will grow because it has a growth rate.

  • 4 years after the original investment, it is approximately $1,093. TRUE

I = 1000x (2.25/100) x 4 =90

1000+90 = $1090

  • It will double in approximately 10 years.

I = 1000x (2.25/100) x 10 =225

1000+90 = $1225

Feel free to ask for more if needed or if you did not understand something.
