Here we can find it by the formula of simple interest 
                               A=P×R×t÷100
                              A=25000×3×10÷100
                              A=2500×3
                             A=7500
Then the population after 10 yrs will be 25000 +7500 = 100000

Population in the zeroth year = 25000

After 1 year it increases to 3%, that is 100% + 3% = 103% = 103/100 = 1.03

So it increases by a multiplying factor of 1.03.

At the end of year 1 = 25000*1.03

At the end of year 2 = 25000*1.03*1.03 = 25000*1.03²

At the end of year 3 = 25000*1.03*1.03*1.03 = 25000*1.03³
...

....

Similarly at the end of 10 years = 25000*1.03¹⁰       evaluate with calculator.

 = 25000*1.03¹⁰ ≈ 33 597.91

So the population at the end of 10 years will be ≈ 33 598

Hope this explains it.

Suppose a researcher is testing to see if a basketball player can make free throws at a rate higher than the NBA average of 75%.
stich3 [128]

Answer: A. Repeated results if the player makes 75% of his shots in the long run.

Step-by-step explanation:

The null distribution is always the opposite of the alternative distribution which in most cases represents the claim or hypothesis which is to be tested or performed. In the scenario given, the challenge is to show that a basketball player has an average higher than that of the NBA. NBA average stands at 75%. The alternative hypothesis is the claim, which is ;

H1 : μ > 75%

THE null is thus :

H0 : μ = 75% ; which means that repeated result of the player will yields an average of 75%

In a class 20 of students, 7 have a cat and
blsea [12.9K]

Answer:

\frac{3}{20}

Step-by-step explanation:

Since there are 20 students, this will be the denominator.

Now, to find how many students have a dog and a cat, you need to subtract all the numbers with 20. The leftover number will be the amount of students.

7+8+8=23

23-20=3

So, there are 3 students who have a dog and a cat.

So, the fraction will be \frac{3}{20}

Mr. Abaya goy P700,000 loan for the expansion of his business payable monthly in 4years. How much os the monthly amortization if
Vaselesa [24]

The monthly amortization is P23,511.63

<h2>Compound interest</h2>

The formula for calculating the compound interest is expressed as:

A = P(1+r/n)^t

whrere:

  • P is the principal = P700,000
  • r is the rate = 12% = 0.12
  • t is the time = 4 years
  • n = 12

Substitute the parameters

A = 700000(1+0.12/12)^{4(12)}\\&#10;A = 700,000(1.01)^{48}\\&#10;A =1,128,558.25

Calculate the monthly payment:

Monthly payment = \frac{1,128,558.25}{48} =23,511.63

Hence the monthly amortization is P23,511.63
