From the table:

At x = 2 and y = 49 ⇒ (x,log(y)) = ( 2 , log 49 ) =  (2, 1.690)

At x = 3 and y = 343 ⇒(x,log(y)) = ( 3 , log 343) =  (3, 2.535)

At x = 4 and y = 2401 ⇒(x,log(y)) = ( 4 , log 2401) =(4, 3.380)

The value of s from the proportion s : t : u = 4 : 9 : 3 is s = 20

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

Let the proportion be in the form s : t : u

where the value of the proportion is

s : t : u = 4 : 9 : 3

And , t - u = 30

Now , assume the value of s = 4x

where x is the unknown we have to calculate

So , the value of t = 9x

And , the value of u = 3x

From the equation , t - u = 30

Substitute the value of t and u in the equation , we get

9x - 3x = 30

6x = 30

Divide by 6 on both sides of the equation , we get

x = 5

Therefore , the value of x is 5

Now , substituting the value of x in the above equation , we get

s = 4x

s = 4 x 5

s = 20

Therefore , the value of s from the proportion is 20

Hence , The value of s from the proportion s : t : u = 4 : 9 : 3 is s = 20

Answer: 2640

Steps:

There are different ways you can solve this

METHOD 1

1. Find what 4% of 22,000 is

0.04 × 22,000 = 880

You do this so that you can find out the increase from the original number of people in the city

2. Find out what 3 years of increase is

880 = 1 year's worth of increase

880 × 3 = 3 year's worth of increase

2640 = 3 year's worth of increase

Therefore the population increase is 2640 ( 12% )

METHOD 2

1. Find out what 12% of 22,000 is

4% = 0.04

12% = 3 × 0.04

12% = 0.12

12% of 22,000 = 0.12 × 22000

12% of 22,000 = 2640

Therefore the population increase is 2640 ( 12% )

What is arithmetic?

Arithmetic is an elementary a part of arithmetic that consists of the study of the properties of the normal operations on numbers—addition, subtraction, multiplication, division, involution, and extraction of roots.

Main BODY:

Let X be the number of professors and Y be the number of lecturers. As the total of both is 228:

X + Y = 228

Then, as there are 5 professors for every 14 lecturers:

5 X = 14 Y or X = (14/5) Y

Replacing this last value of X on the first equation:

(14/5) Y + Y = 228

(14/5) Y + (5/5) Y = 228

(19/5) Y = 228

Y = 228 * (5/19)

Y = (228*5)/19

Y = 1140 / 19

Y = 60

Then we can find X:

X = (14/5) Y = (14/5) * 60 = 168

X = 168

Hence thre are 60 professors and 168 lecturers.

The fraction of related CIs over the long run that actually contain the parameter's true value is what is meant by the confidence level. The parameter's true value, for instance, should be present in 95% of all intervals computed at the 95% level. The range of values within the 95% confidence interval represents the population's actual mean, with 95% confidence. The sample mean (the center of the CI) will differ between samples due to natural sampling variability. The process itself, not a certain CI, is what inspires confidence. According to the 68-95-99.7 Rule, 95% of values are within two standard deviations of the mean, hence to calculate the 95% confidence interval, one need only add and deduct two standard deviations from the mean.

At 99% confidence interval the critical value is [tex]z_{0.005}[/tex]=2.58

a) After 10 years, the amount (future value) in the mutual fund will be $27,679.22.

b) The total amount deposited in the mutual fund is $23,000.

c) The amount of interest earned on the quarterly deposits is $4,679.22.

The future value is the compounded present value of periodic deposits.

The future value is compounded at an interest rate per period.

We can compute the future value using an online finance calculator, which also shows the total deposits and interest earned.

N (# of periods) = 40 quarters (10 years x 4)

I/Y (Interest per year) = 3.7%

PV (Present Value) = $0

PMT (Periodic Payment) = $575

Results:

Future Value (FV) = $27,679.22

Sum of all periodic payments = $23,000 ($575 x 40 quarters)

Total Interest = $4,679.22

Thus, making a quarterly deposit of $575 for 10 years at 3.7% APR will yield a future value of $27,679.22.
