The mean amount of time it takes a kidney stone to pass is 12 days and the standard deviation is 4 days. Suppose that one indivi
Bezzdna [24]

The probability that a randomly selected person with a kidney stone will take longer than 16 days to pass it is 0.15866 ,  the minimum number for the upper quarter of the time to pass a kidney stone days is 14.4 .

<h3>What is Probability ?</h3>

Probability is the measure of likeliness of an event to happen

Let X denote the time to pass the kidney stone.

The random variable X follows normal Distribution

mean = 12 days days

standard deviation = 4 days

The distribution of X is  X - N ( 12 , 4)

The probability that a randomly selected person with a kidney stone will take longer than 16 days to pass it is

P ( X > 16) = 1 - P( X ≤ 16)

= 1 - P( Z ≤ (16-12)/4)

= 1 - P ( Z ≤ 1 )

= 1 - 0.84134

= 0.15866

P( X < x₀) = 0.75

\rm P ( \dfrac{x - \mu }{\sigma} < \dfrac{x_0 -13}{6}) = 0.75

\rm \phi (\dfrac { x_o - 12}{4}) = 0.75

Using the excel function the z score for the area 0.75 is

z - score = 0.6745

\rm \dfrac {x_o - 12}{4} = 0.6745

x₀  = 0.6 * 4 + 12

x₀ = 14.4

Vinnie is searching online for airline tickets. Two weeks ago, the cost to fly from Denver to Hartford
OLEGan [10]

Answer:

The ticket increased 57% of its original price

The baggage price was 44.5 increased 0.11% and then became 50

Step-by-step explanation:

So if the amount was 200 and now is 350, we should use division.

200 ÷ 350 = 0.5714285714285714 which you can round to 0.57 or as many digits as the question asked for. In thise case I will use 0.57

0.57 converted to percentage is 57%

About the second question

now you know the amount after increase and the percentage. So all you have to do is reverse.

11% = 0.11

0.11  ✕ 50 = 5.5    

this means the price increased 5.5

50 - 5.5 = 44.5

In one week Wendy made withdraws of $45.38, $162.65, $13.00, and $51.99 to pay for various expenses. She deposited a $150 check
wolverine [178]

A = total deposits = 150.00+22.50 = 172.50

B = total withdraws = 45.38+162.65+13.00+51.99 = 273.02

C = net change = A - B = 172.50-273.02 = -100.52

The net change is negative, so Wendy lost 100.52 dollars for the week.
