Suppose that a student is randomly selected from a large high school. The probability that the student is a senior is 0.22. The
lawyer [12517]

Answer: La probabilidad que necesitamos es 0.16.

Step-by-step explanation:

Se nos proporciona que

La probabilidad de que el estudiante sea un senior = 0.22

La probabilidad de que el estudiante tenga una licencia de conducir = 0.30

La probabilidad de que el estudiante sea un senior o tenga una licencia de conducir = 0.36

Buscamos la probabilidad de que el estudiante sea un senior y tenga licencia de conducir.

Según la pregunta,

P(S\cap D)=P(S)+P(D)-P(S\cup D)\\\\P(S\cap D)=0.22+0.30-0.36\\\\P(S\cap D)=0.16

Por lo tanto, la probabilidad que necesitamos es 0.16.

Jake forgot to replace the cap on a bottle of deodorant. The deodorant began to evaporate at the rate of 12% per day. If the ori
PIT_PIT [12445]

Answer:

graph representing the function f of x equals 30 multiplied by 0.88 raised to the exponent of x

Step-by-step explanation:

The deodorant starts to evaporate, indicating a mass reduction, thus 12% represents the decay rate. In exponential decay, the function's graphical representation adheres to the formula:

y=a(1-r)^x

Where a signifies the starting quantity (a=30), r is the decay rate (r=0.12) and x denotes the time intervals, measured in days for this case. By inserting the given values into the formula:

y=30(1-0.12)^x\\y=30(0.88)^x

Which aligns with the "graph representing the function f of x equals 30 multiplied by 0.88 raised to the exponent of x".

Hospital sends an invoice to a patient. The patient schedules a payment plan in which she makes an initial payment of $1,451 the
lawyer [12517]
In the first month, she made a payment of $1451

In the second month, she paid one-third of that, which amounts to:
1451/3 = 483.66

For the third month, she pays one-third of 483.66 as indicated, meaning she takes one-third of the prior month's payment.

483.66/3 = 161.22

In the fourth month, her payment was

161.22/3 = 53.74

Altogether, her total payments amounted to:

$2149.62 - B.

If you ask three strangers about their birthdays, what is the probability:
Inessa [12570]
Part A:

The probability that all three strangers have their birthdays on a Wednesday is calculated as

\left( \frac{1}{7} \right)^3= \bold{\frac{1}{343}}



Part B:

The probability that the birthdays of the three individuals fall on distinct days throughout the week is calculated as

\left( \frac{1}{7} \right)\left( \frac{1}{6} \right)\left( \frac{1}{5} \right)= \bold{\frac{1}{210}}



Part C:

The probability that none of the three have their birthdays on a Saturday is determined by

\left( \frac{6}{7} \right)^3= \bold{\frac{216}{343}}
