How do you calculate modus?

Answer:

  $824.39

Step-by-step explanation:

You want to know the monthly deposit required for a 50-year ordinary annuity to accumulate enough value at 5% so that annual withdrawals can be made of $110,000 without affecting the principal.

In order for the annual interest to be $110,000 at 5%, you have ...

  I = Prt

  110,000 = P(0.05)(1)

  2,200,000 = P . . . . . . . multiply by 20

The value of the annuity must be $2.2M after 50 years.

In order for the annuity to have that future value, the monthly payment must be $824.39. This value can be found using a suitable financial calculator or spreadsheet. (Or the appropriate formula from your list.)

(V2-V1)|V1|×100

=(12−9)|9|×100

=3/9×100

=0.333333×100

=33.33%

Answer:

1). If the algae doubles every day, it will take 15 days for it to cover half the lake. This means it would happen on January 15.

2). Your friend may be skeptical because they may not believe that the algae can grow so quickly and cover the entire lake in just 30 days. Alternatively, they may not believe that you have accurate information about the situation.

3). Removing most of the algae on January 29 would significantly reduce the amount of algae in the lake and would likely help prevent the lake from becoming completely covered. However, if 1% of the surface is still covered with algae on February 1, it is possible that the problem has not been fully solved and the algae could continue to grow and potentially become a problem again in the future. It would be best to continue monitoring the lake and taking action to prevent the algae from growing.

The point H is at 2.5 on the number line

Here we know that point F is at 4 and point G is at -2.

The distance between these 2 points is

4 - (-2)

= 4 + 2 units

= 6 units.

Now let the point H be at x on the number line.

Now it is given that

FH:GH = 3:9

or, FH/GH = 3/9

or, (4 - x) / (x - (-2)) = 3/9

or, (4 - x)/(x + 2) = 1 /3

or, 12 - 3x = x + 2

or, 4x = 10

or, x = 2.5

Hence point H is at 2.5

When the area of a figure is enlarged by a scale factor of 3, then the area of the figure will be three times of the original area of the figure.

Here, the area of the figure is enlarged by a scale factor of 3

The scale factor is defined as the ratio between the scales of the original object or measurement and the new measurement or object

When the scale factor is greater than 1 the size of the new figure will increase and if the scale factor is less than 1 size of the new figure decreases

Here scale factor is 3, so the area of the figure is increased by three times

Therefore, the the area of the new figure will enlarged by three time

If we roll a dice three times and we can stop in the first time only when it come 6. The expected payoff is 4.557.

According to the question:

The number of times you can get 06 are:

(i). If the third toss rolls a 6:  6

In this case her first two digits can be any of the five numbers. No. The number of cases is 5 × 5 = 25.

(ii). If you get a 6 on the second throw. The number of cases is -5 (no third throw in this case)

(iii). If the first roll rolls a 6. The number of cases is -1.

2. Number of times you can get 5 Are-

(i). If there is only one 5 in 3 rolls . The number of cases will simply be

3 × 4 × 4

(Because there are 5 possibilities in 3 places and 4 in the remaining places.)

(ii). If there are two 5s, the number of cases is 3×4. (Because there are 3 places where 5 cannot exist, and the places are filled with 4 possibilities.)

(iii). If there are three 5s, the number of possibilities is -1.

Similarly, for 4,3,2,1, the number of possibilities is (3*3*3 + 3*3 + 1), (3*2*2 + 3*2 + 1), (3 × 1×1 + 3×1 + 1), 1 each.

So the number of possibilities for 1,2,3,4,5,6 are 1,7,19,37,61,31 respectively .

You can now get the expected profit by taking the weighted average of the numbers with the possible outcome odds.

So the result is (6*31 + 5*61 + 4*37 + 3*19 + 2*7 + 1)/(31+61+37+19+7+1)

which is 711/ 156 = 4.557

Distance from the top of the tree to the tip of the shadow is 15.46 feet

What is Trigonometry?

Trigonometry shows the relationship between sides and angles of a right angled triangle.

There are six trigonometrical functions

[tex]sin \theta, cos \theta, tan \theta, cot \theta, sec \theta, cosec \theta[/tex]

[tex]sin \theta = \frac{Perpendicular}{Hypotenuse}\\\\cos \theta = \frac{Base}{Hypotenuse} \\\\tan \theta = \frac{Perpendicular}{Base} \\\\cot \theta = \frac{Base}{Perpendicular} \\\\sec \theta = \frac{Hypotenuse}{Base} \\\\cosec \theta = \frac{Hypotenuse}{Perpendicular} \\\\[/tex]

Let the angle of elevation be [tex]\theta[/tex] and distance from the top of the tree to the tip of the shadow be d feet

Here the tree represents the perpendicular, shadow represents the base and distance from the top of the tree to the tip of the shadow represents the hypotenuse

A tree that is 15 feet tall casts a shadow that is 4 feet long

[tex]tan\theta = \frac{15}{4}\\\theta = tan^{-1}( \frac{15}{4})\\\theta = 75.1^{\circ}[/tex]

Now,

[tex]sin75.1^{\circ} = \frac{15}{d}[/tex]

[tex]0.97 = \frac{15}{d}\\d = \frac{15}{0.97}\\d = 15.46 \ feet[/tex]

Part A) If the original price of the model car was $40, and it was sold on the third day, with a daily discount of 5%, the sales amount is $34.30.

Part B) The percentage discount from the original price is 14%.

The percentage discount is the total discount divided by the original price multiplied by 100.

In this instance, we compute the total discount as $5.70, then express this value as a numerator with $40 as the denominator.  The quotient is multiplied by 100.

Original price of the model car = $40

Daily discount = 5%

The date the car sells = the third day

The sales price on the third day = $34.30 ($40 x 95% x 95% x 95%)

Total discounts = $5.70 ($40 - $34.30)

c. Outside the triangle

The circumcenter is the point of intersection of the perpendicular bisectors of the sides of the triangle.

The location of the circumcenter can be inside the triangle, outside the triangle, or on the triangle.

The circumcenter is located on the inside of an acute triangle, while it is located on the hypotenuse side of a right triangle.

The circumcenter is the location of the center of the circle that circumscribe the triangle, such that in an acute triangle, the angle at the center (twice the angle at the circumference), is always less than 180°, which is the angle made by the diameter, which keeps the diameter line and the circumcenter, passing inside the triangle.

Answer: B.83

Step-by-step explanation:

The number 2,158 is called the numerator or dividend, and the number 26 is called the denominator or divisor.

The quotient of 2,158 and 26, the ratio of 2,158 and 26, as well as the fraction of 2,158 and 26 all mean (almost) the same:

2,158 divided by 26, often written as 2158/26. 2,158 divided by 26 = 83

The result of 2158/26 is an integer, which is a number that can be written without decimal places.

   2158 divided by 26 in decimal = 83

   2158 divided by 26 in fraction = 2158/26

   2158 divided by 26 in percentage = 8300%

If p1, p2 and p3 are probabilities of surviving for years 1, 2 and 3 respectively, then the cumulative probability of surviving for 3 years is p1 + p2 + p3

The probability of surviving for 1 year = p1

The probability of surviving for 2 year = p2

The probability of surviving for 3 year = p3

The probability is the ratio of the number of favorable outcomes to the total number of outcomes.

The cumulative probability is defined as the probability distribution of random variables

The cumulative probability = p1 + p2 + p3

Therefore, the cumulative probability of surviving for 3 years is  p1 + p2 + p3

Answer:

In an exponential equation, both sides can be written as power of the same base when the base is the same on both sides of the equation. For example, the equation "2^x = 8" can be rewritten as "2^x = 2^3" because the base, 2, is the same on both sides of the equation.

To solve an exponential equation where both sides can be written as powers of the same base, you can set the exponents equal to each other and solve for the variable. In the example above, setting the exponents equal to each other would give us "x = 3", so the solution is x = 3.

On the other hand, in an exponential equation where both sides can not be written as powers of the same base, you cannot simply set the exponents equal to each other. Instead, you need to use a different method to solve the equation. One way to do this is to use the property of exponents that states that "a^x * a^y = a^(x+y)" to rewrite the equation so that both sides have the same base. For example, the equation "2^x * 3^y = 6" can be rewritten as "2^x * 2^(log3(6)) = 2^(x + log3(6))", where "log3" represents the logarithm with base 3. This allows us to set the exponents equal to each other, giving us "x + log3(6) = 1", and we can solve for x to find the solution.
