Answer: the amount of the annuity is $501000

Step-by-step explanation:

We would apply the future value which is expressed as

FV = C × [{(1 + r)^n - 1}/r]

Where

C represents the yearly payments.

FV represents the amount of money

in your account at the end of 25 years.

r represents the annual rate.

n represents number of years or period.

From the information given,

r = 4% = 4/100 = 0.04

C = $12000

n = 75 - 50 = 25

Therefore,

FV = 12000 × [{(1 + 0.04)^25 - 1}/0.04]

FV = 12000 × [{2.67 - 1}/0.04]

FV = 12000 × 41.75

FV = $501000

Answer:

  about 21.9%

Step-by-step explanation:

The effective annual multiplier is ...

  (1 +r/n)^n = (1 +0.20/12)^12 ≈ 1.21939

The rate equivalent is 1 less than this:

  1.21939 -1 = 0.21939 = 21.939%

Answer:

A: 15%

Step-by-step explanation:

First test:

15 ÷ 20 = 0.75

0.75 * 100 = 75%

Second Test:

18 ÷ 20 = 0.9

0.9 * 100 = 90%

90% - 75% = 15%

Answer:

Answer:

M^3

Step-by-step explanation:

28 hours because they are too long from each other

Answer:

Approximately 6.86 hours.

Step-by-step explanation:

Renee sews at a rate of 1.5625 sq ft an hour. Found using square feet divided by hours.

Genera sews at a rate of 2.084 sq ft an hour. Found using square feet divided by hours.

To find how fast they can sew the quilt together, we must add their sewing speeds together: 1.5626 + 2.084 = 3.64583333.

Using this equation we can divide a 25 sq ft quilt by their speed of 3.64583333 to get approximately 6.86 hours.

The answer is approximate because we used rounded decimals.

Answer:

Answer c:  1000

Step-by-step explanation:

Set f(x) = 2 log x - 6 = 0 as a first step in finding the zero or zeros.

2 log x - 6 = 0  becomes log x - 3 = 0 after dividing all three terms by 2.

Then log x = 3, and because "log x" has base 10, the value of x is 10^3, or 1000.

Answer:

n = -1.5

Step-by-step explanation:

[tex]\frac{1}{(\sqrt2)^{3} } } = 0.353553[/tex]

log ( [tex]2^{n}[/tex] ) = log (.353553)

n = [tex]\frac{log (0.353553) }{log (2)} = -1.5[/tex]

Answer:

1) Yes, table shows a probability distribution

2) Mean = 1.5

3) Standard Deviation = 1.1

Step-by-step explanation:

PART 1:

For the table to show a probability distribution, the sum of all probabilities should be equal to 1

Sum of probabilities = 0.358 + 0.443 + 0.174 + 0.025

Sum of probabilities = 1

Hence, the table shows the probability distribution.

PART 2:

The formula for mean is given by:

Mean = Sum of terms/ Total no. of terms

Mean = (0+1+2+3) / 4

Mean = 1.5

PART 3:

The formula for standard deviation is given by:

[tex]\sigma=\sqrt{\frac{\sum(x_i-\mu)^2}{N}}[/tex]

Solve using a calculator, we get

σ = 1.118

Round off to one decimal place

σ = 1.1

Answer:

The correct answer is: Calculate income, Total up spending, Categorize expenses, Determine if spending is below income, and Reduce expenses in flexible categories to save or increase savings. When making a budget, it's first necessary to figure out how much money comes in and goes out, and then to compare expenses to income to make cuts if necessary.

Answer:

585.53 new balance

$839.78 - 110.50 - 143.75

Answer: 585.53

Step-by-step explanation:

839.78 - 110.50 = 729.28

729.28 - 143.75 = 585.53

Answer: Hyperbolic geometry

Step-by-step explanation:

Hyperbolic triangle is a non - Euclidean triangle in which the sum of the angles of the triangle is not up to 180 degrees. That is, less than 180 degree.

Euclidean geometry is the normal geometry that is being taught in school in which the sum of the angles of its triangle equals 180 degrees

While spherical geometry is a non euclidean geometry with sum of the angles of its triangle greater than 180 degrees.

Therefore, the triangle that has angle measures of 45°, 61°, and 70° is a non - Euclidean geometry which is hyperbolic geometry.

Answer:

x =  (k-c)/8

Step-by-step explanation:

8x+c= k

Subtract c from each side

8x+c-c= k-c

8x = k-c

Divide each side by 8

8x/8 = (k-c)/8

x =  (k-c)/8
