Question 1 A physician's “patient panel” is the list of all patients under their care. In the
US, the size of patient panels among primary care doctors is well modeled by a N(1500, 200)
distribution.

(a) If a "medium-sized” panel has anywhere from 1250 to 1750 patients, what proportion
of US primary care doctors have a patient panel that is NOT "medium-sized”?
(b) Find Q1,Q3 and the IQR of the patient panels of US primary care doctors.

Answers

Using the normal distribution, we have that:

a) The proportion of US primary care doctors have a patient panel that is NOT "medium-sized” is 0.2112.

Q1 = 1365.

Q2 = 1635.

IQR = 270.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

For this problem, N(1500, 200) means that [tex]\mu = 1500, \sigma = 200[/tex].

Item a:

The proportion that are medium-sized is the p-value of Z when X = 1750 subtracted by the p-value of Z when X = 1250, thus:

X = 1750:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1750 - 1500}{200}[/tex]

[tex]Z = 1.25[/tex]

[tex]Z = 1.25[/tex] has a p-value of 0.8944.

X = 1250:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1250 - 1500}{200}[/tex]

[tex]Z = -1.25[/tex]

[tex]Z = -1.25[/tex] has a p-value of 0.1056.

0.8944 - 0.1056 = 0.7888 are medium.

1 - 0.7888 = 0.2112.

The proportion of US primary care doctors have a patient panel that is NOT "medium-sized” is 0.2112.

Item b:

Q1 is the first quartile, which is the 25th percentile, given by X when Z has a p-value of 0.25, so X when Z = -0.675. Then:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.675 = \frac{X - 1500}{200}[/tex]

[tex]X - 1500 = -0.675(200)[/tex]

[tex]X = 1365[/tex]

Thus, Q1 = 1365.

Q3 is the third quartile, which is the 75th percentile, given by X when Z has a p-value of 0.75, so X when Z = 0.675. Then:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.675 = \frac{X - 1500}{200}[/tex]

[tex]X - 1500 = 0.675(200)[/tex]

[tex]X = 1635[/tex]

Thus, Q3 = 1635.

The IQR is the difference between Q3 and Q1, that is:

[tex]IQR = Q3 - Q1 = 1635 - 1365 = 270[/tex]

Then, IQR = 270.

The number of friends who received an email on Wednesday can be obtained using the exponential relation between the initial number of mails and the number of days elapsed, which is 125 .

The initial number of friends who received an email = 5 friends.

Number of days elapsed from Monday to Wednesday = 3 days

The Number of people who received a mail on Wednesday can be expressed thus :

5³ = 5 × 5 × 5 = 125 friends.

f(x)=10-9/2x
if f(x)=-53x find x

Answers

Answer:

x = -20/97

Step-by-step explanation:

f(x) = -53x is your output

so -53x = 10-9/2x

-53x - 10 = -9/2x

lets clear the fraction by multiplying each side by 2

-106x - 20 = -9x

-97x = 20

x = -20/97

When f(x) is equal to -53x, the value of x is approximately -0.2062. To find the value of x when f(x) is equal to -53x, we can set the two expressions equal to each other and solve for x:

Given: f(x) = 10 - (9/2)x , And: f(x) = -53x

Setting them equal to each other: 10 - (9/2)x = -53x

To solve for x, let's first get rid of the fraction. We can do this by multiplying the entire equation by 2: 2 * (10 - (9/2)x) = 2 * (-53x)

20 - 9x = -106x

Now, let's isolate the variable x on one side of the equation. Let's move the -9x term to the other side by adding 9x to both sides:

20 - 9x + 9x = -106x + 9x

20 = -97x

Finally, to find x, divide both sides by -97: x = 20 / -97

x ≈ -0.2062 (rounded to 4 decimal places)

So, when f(x) is equal to -53x, the value of x is approximately -0.2062.

What is percentage?

A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.

Given:

Sharon's pay = $30000,

Raise percentage = 10%,

Samantha pays = $40000,

Raise by = $1000,

Calculate Sharon's pay as shown below,

Sharon's pay = 30000(1 + 0.10)⁴

Sharon's pay = 30000 × 1.77

Sharon's pay = $43923

Calculate pay of Samantha after 4 years,

The pay of Samantha = 40000 + 4 × 1000

The pay of Samantha = $44000

Thus, Sharon's annual salary first exceeds Samantha's after 4 years.
