It takes 8 months for the investment to grow to $6000 if interest was compounded quarterly.

What is compound interest?
The interest charged on a loan as well as deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The main distinction between compound as well as simple interest is this.

Given:

Principal amount = $5000

Annual amount interest = 2.6%

Compounded quarterly = 4

Final amount = $7000

Formula:

A = P(1 + r)^4n - 1

A is the quarterly compounded interest.

P would be the principal amount.

r is the quarterly compounded rate of interest.

n is the number of periods.

Solving it:

7000 = 5000 (( 1 + 0.026))^ 4t -1

7/5 = (( 1 + 0.026))^ 4t

7/5 = (1.026)^ 4t -1

ln (7/5) = 4t ln (1.006) - ln 1

t = 7.61 months

t ~ 8months

Hence, it takes 8 months for the investment to grow to $6000 if interest was compounded quarterly.

d = 6 - 5

d = 1

This expression is in arithmetic progression.

a = 5

n = 95

sum of n terms = n/2(2a+(n-1)d)

Domain of P is (1991, 1992, 1993,  ............)

Range of P is (29900, 29100, 298300, .........)

In 2010 there will be 14,700 population

How do you determine a domain's and range's?

How Can I Determine an Equation's Domain and Range? In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).

Given that

In 1995 there will be 26700 population and in 2003 there will be 20300 population

So in above statement we can form 2 linear equations

26700=m(1991)+b

20300=m(2003)+b

by this we can solve for m and b

m = -800

b= 1622700

By this now we can find the year for population of 14700

The interval that represents the middle 95% of his commute times is [45 , 55]

What is standard deviation ?

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.

Where:

68% is the first standard deviation

95% is the second standard deviation about the mean

99.7% is the 3rd standard deviation about the mean.

Therefore. the middle 95% interval is calculated as:

CI = µ + 2 σ

Answer: The shorter piece is 8 ft and the longer piece is 19 ft.

Step-by-step explanation:

     Let x be the shorter piece. We will write an equation that represents the original problem to help us solve.

           27 ft = x + (2x + 3)

     Now, we will solve this equation.

27 ft = x + (2x + 3)

27 ft = 3x + 3

24 ft = 3x

8 ft = x

     The shorter piece is 8 ft long.

     Then, we will use substitution for the longer piece.

2x + 3

2(8) + 3

19

     The longer piece is 19 ft long.

The solution set to the inequality, -1/2m ≥ 7/11, is: m ≤ -14/11 (see attachment for the graph).

Translating the statement given as an inequality, we have:

-1/2m ≥ 7/11

To find the solution, isolate the variable of m to one side of the inequality:

-1/2m ≥ 7/11

Multiply both sides by -2 then change the sign to

-1/2m(-2) ≥ 7/11(-2)

m ≤ -14/11

Therefore, it means the solution is any value of m that is less than or equal to -14/11.

Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines.

As we know, parallel lines never intersect.

Parallel lines result from changing the y-intercept while keeping the slope constant.

The original line and the transformed line are always parallel since translations do not alter the slope of the line.

What is the Normal Probability Distribution?

The Normal (or Gaussian) distribution is the most common continuous probability distribution. The function calculates the likelihood that an event will occur between any two real number limits as the curve gets closer to zero on either side of the mean. The area beneath the normal curve is always one.

Problems of normal distributions can be solved using the z-score formula.

In a set with mean  and standard deviation, the z-score of a measure X is:

[tex]z = \frac{x - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

This is the P value of Z when X = 98.

[tex]z = \frac{x - \mu}{\sigma}[/tex]

z = (99 -100)/15

z = -0.066

z = -0.066 has a P value of 0.2456

Answer:

Step-by-step explanation:

1) 4v + 7 = 7, for v?

→ 4v + 7 = 7

→ 4v = 7 - 7

→ v = 0/4

→ [ v = 0 ]

2) 3(u + 4) = 27, for u?

→ 3(u + 4) = 27

→ 3u + 12 = 27

→ 3u = 27 - 12

→ u = 15/3

→ [ u = 5 ]

3) -20 = 10(h + 5), for h?

→ -20 = 10(h + 5)

→ 10h + 50 = -20

→ 10h = -20 - 50

→ h = -70/10

→ [ h = -7 ]

4) -10 = (n - 52)/5, for n?

→ -10 = (n - 52)/5

→ n - 52 = -10 × 5

→ n = -50 + 52

→ [ n = 2 ]

5) (48/x) - 3 = 3, for x?

→ (48/x) - 3 = 3

→ 48/x = 3 + 3

→ 6x = 48

→ x = 48/6

→ [ x = 8 ]

6) 8r = 2r + 42, for r?

→ 8r = 2r + 42

→ 8r - 2r = 42

→ r = 42/6

→ [ r = 7 ]
