Harper Hospital treated 423 patients last week who were children, out of a total of 931 patients. The administrator calculates t

hat they had 408 adult patients. Is the administrator's calculation reasonable? Estimate the number of adult patients by rounding the numbers to check the administrator's calculation.
A) The administrator's calculation is reasonable because my estimate of 500 is fairly close to 408.
B) The administrator's calculation is reasonable because my estimate of 400 is fairly close to 408.
C) The administrator's calculation is not reasonable because my estimate of 500 is not close to 408.
D) The administrator's calculation is not reasonable because my estimate of 400 is not close to 408.

Hi there!

The correct answer is C) The administrator's calculation is not reasonable because my estimate of 500 is not close to 408. Let's use rounding to find our estimate. 423 is close to 400 and 931 is close to 900. If we subtract 400 from 900, we know that there was approximately 500 adults. Since 408 is not near 500, the administrator's calculation is not reasonable. In fact, they were 100 off from the correct calculation, also making it not reasonable.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Answer:

The Answer is C.) The administrator's calculation is not reasonable because my estimate of 500 is not close to 408.

Step-by-step explanation:

Round each number to the nearest hundreds.

423 → 400

921 → 900

Estimate = 900 − 400 = 500

Actual number of adult patients = 931 − 423 = 508

The administrator miscalculated the number of adult patients.

A bicycle store costs ​$3300 per month to operate. The store pays an average of ​$75 per bike. The average selling price of each
Klio2033 [76]
S=Selling price 135
V=Variable cost 75
F=Fixed cost 3300
Let quantity be Q
The formula to break even is
135Q-75Q-3300=0
Solve for Q
60Q-3300=0
60Q=3300
Q=3300/60
Q=50
So the store must sell 50 bicycles to break even

Hope it helps!

An airline finds that 5% of the persons making reservations on a certain flight will not show up for the flight. If the airline
vivado [14]

Answer:

The answer to the question is;

The probability that a seat will be available for every person holding a reservation and planning to fly is 0.63307.

Step-by-step explanation:

Let the sample size =n = 100

The success probability = 5 % = 0.05

Number of tickets sold = 105 tickets

In the case where there the airline has found that 5 % will not show up, then every passenger should have  a seat, we have  

A Binomial distribution is appropriate where there is a chance for a certain number of successful outcomes from a number of independent trails

However n·p and n·q must be ≥ 5 for there to be a normal approximation of a Binomial distribution thus

n·p = 105×0.05 =  5.25 ≥ 5

and n·q = n(1 - p) = 105 (1 - 0.05) = 99.75 ≥ 5

As the requirements are met, we can proceed with the approximation of the Binomial distribution by the normal distribution

 z = \frac{x-np}{\sqrt{np(1-p)}  } = \frac{4.5 - 105*0.05}{\sqrt{105*0.05(1-0.05)} } =  - 0.3358

We therefore have P(x ≥ 5) = P( x > 4.5) = P(z > -0.34) = 1 - P(z < -0.34) = 1 -0.36693 = 0.63307

Another way to solve the question is as follows

p = 0.95 q = 0.05

μ = np = 0.95*105 = 99.75, σ = \sqrt{npq} = 2.233

P (x≤100) = P(z = P(z<0.34) = 0.63307.

taurus [48]

Answer:

V/(pi r^2)  = d

Step-by-step explanation:

V = pi r^2 d

Divide each side by pi r^2

V/(pi r^2)  = pi r^2 d/(pi r^2)

V/(pi r^2)  = d

Then substitute the values into the equation to find d
