Using the volume of the spherical balloon, it is found that it will take 24 hours for the balloon to become completely empty.

<h3>What is the volume of a sphere?</h3>

The volume of a sphere of radius r is given by:

V = \frac{4\pi r^3}{3}

Aspherical balloon has a radius of 6 feet, hence the volume is:

V = \frac{4\pi 6^3}{3} = 905

It has already lost 20% of it's air, and air is leaking out of the balloon at a rate of 30 cubic feet per minute, hence the volume after t minutes is given by:

V(t) = 0.8(905) - 30t

V(t) = 724 - 30t

It will be completely empty when:

V(t) = 0

724 - 30t = 0

30t = 724

t = \frac{724}{30}

t = 24.1

Rounding, it will take 24 hours for the balloon to become completely empty.

The student body president of a high school claims to know the names of at least 1000 of the 1800 students who attend the school
natali 33 [55]

Answer: Population = Total students attend the school.

Parameter = Proportion of students named by president correctly.

Step-by-step explanation:

Population for a particular study is the largest possible group of individuals that are essential to be considered.

Parameter = measure of characteristic in a population.

By the above definition, we have

Population = Total students attend the school(1800).

Parameter = Proportion of students named by president correctly.

A bank loans a customer $100,000 for a period of 2 years. The simple interest rate of the loan is 5.7%. What is the total amount
puteri [66]
R = monthly loan rate = 5.7 / 1200 = <span> <span> <span> 0.00475 </span> </span> </span>
n - number of payments
p - principal
Total Loan Cost = (r * p * n) / [1-(1+r)^-n]
Total Loan Cost = ( <span> <span> <span> 0.00475  </span> </span> </span> * 100,000 * 24) / [1 -(1<span>.00475)^-24]
</span>Total Loan Cost = 11,400 / 1 -(1.00475^-24)
Total Loan Cost = 11,400 / 1 -<span><span>.8924988049 </span>
</span><span>Total Loan Cost = 11,400 / </span> <span> <span> <span> 0.1075011951 </span> </span> </span>
Total Loan Cost = <span> <span> <span> 106,045.33 </span> </span> </span>
