Answer:

480 minutes or ≈ 8 hours

Step-by-step explanation:

We know that Enrique walks one mile each day for 4 days of the week. We also know that the estimated time it would take for him to complete the mile is about 14 to 16 minutes. To make it easier, let's use 15 minutes. The question is asking to estimate the number of minutes Enrique would walk within a span of 8 weeks. Let's start with the equation that represents the number of miles Enrique would walk in weeks.

So we have the fact that he walks 4 days out of the week, now though the question asks the equation to represent the number of miles, the obvious answer is 4x, 4 representing the days, and x representing the number of minutes. I would say it's safe to assume that the equation should represent the amount of time he would take, which would also be represented with 4x.

As for the equation : 4x is your answer.

Now we need to explain how I determined the estimate, so let's do the math.

Since we are using 15 minutes to represent the estimate, we could replace x with 15 in the equation 4x.

4(15)

60 minutes

Meaning that in one week, Enrique would spend around 1 hour walking. Now we need to look for the amount of time within an 8 week span, so do the following and multiply 60 by 8 :

60 * 8

480 minutes

Therefore, within an 8 week span, Enrique would spend about 480 minutes or 8 hours walking.

Suppose that each semester at a particular community college Manuel has to pay $1478 in tuition and $121 in fees.
Kamila [148]

Answer:

Step-by-step explanation:

<em>Let x be time, in semesters, remaining before Manuel graduates</em>.  We find that Manuel's expenses are:

$1478/semester in tuition, and

$121/semester in fees

1.  <u>x semesters remaining:  fees</u>

  Remaining cost for fees, y, is the product of the fee times the number of semesters, x:

y =($121/semester)*x

y = ($121)*x

2.  <u>x semesters remaining:  tuition</u>

  Remaining cost, y, is the product of the tuition (times the number of semesters, x.  

y = ($1478/semester)*x + ($121/semester)*x

y = ($1599)*x

3.  <u>x semesters remaining:  tuition and fees</u>

  Remaining cost, y, is the sum of the products of the tuition (times the number of semesters, and the fees (tix.  

y = ($1478/semester)*x + ($121/semester)*x

y = ($1599)*x

Before every​ flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the ai
ollegr [7]

Answer:

The probability that the aircraft  is  overload = 0.9999

Yes , The pilot has to be take strict action .

Step-by-step explanation:

P.S - The exact question is -

Given - Before every​ flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 37 ​passengers, and a flight has fuel and baggage that allows for a total passenger load of 6,216 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6216/37 = 168 lb. Assume that weight of men are normally distributed with a mean of 182.7 lb and a standard deviation of 39.6.

To find - What is the probability that the aircraft is​ overloaded ?

         Should the pilot take any action to correct for an overloaded aircraft ?

Proof -

Given that,

Mean, μ = 182.7

Standard Deviation, σ = 39.6

Now,

Let X be the Weight of the men

Now,

Probability that the aircraft is loaded be

P(X > 168 ) = P(\frac{x - \mu}{\sigma} > \frac{168 - \mu}{\sigma} )

                 = P( z > \frac{168 - 182.7}{39.6} )

                 = P( z > -0.371)

                 = 1 - P ( z ≤ -0.371 )

                 = 1 - P( z > 0.371)

                 = 1 - 0.00010363

                 = 0.9999

⇒P(X > 168) = 0.9999

As the probability of weight overload = 0.9999

So, The pilot has to be take strict action .
