A: The denominator doubles every step.

B: 1/16 1/32 1/64

Answer:

mean = 23

median = 22.50

mode = 20

range = 7.5

Step-by-step explanation:

mean is the total / n

total = 20+20+22.50+25+27.50 = 115

n= 5

mean = 115/5 = 23

median you'll arrange the numbers in ascending order and pick the middle one and its 22.50

20, 20, [22.50], 25, 27.50

mode is the number that is repeated mostly and it was 20.

range is max - min

max is 27.50

min is 20

range = 27.50 - 20

range = 7.50

By taking the quotient between the total debt and the number of people, we conclude that the debt per person is $2,622

To find the amount of debt per person, we need to find the quotient between the total amount of debt and the number of people.

Here the total debt is:

$6.39 billion = $6.39*10^9

And the total number of people is:

2.437 million = 2.437*10^6

Then the quotient is:

Q = ($6.39*10^9)/( 2.437*10^6) = $2.622*10^3

The debt per person is:

Q = $2.622*10^3 = $2,622

The probability of selecting red marble is 0.444.

Probability is calculated using the formula :

Probability = number of favourable outcomes ÷ total number of outcomes

Number of favourable outcomes = number of red marbles in box

Number of favourable outcomes = 8

Total number of outcomes = total number of marbles

Total number of outcomes = 8 + 4 + 6

Total number of outcomes = 18

Keep the values in formula of probability to find the probability of selecting red marble

Probability = 8 ÷ 18

Performing Division by 2

Probability = 4/9

Representing in decimal round to three decimal places = 0.444

Hence, the probability of selecting red marble is 0.444.

Step-by-step explanation:

Suppose $2000 is deposited in a bank account with an annual compound interest rate of 3%. After two years, we will have accumulated 121.80 in interest on your initial 2000 deposit.

Compound interest is, to put it simply, interest that is earned on interest. Compound interest is interest that is earned on both the initial principal and interest that builds up over time in a savings account.

There may be a difference in the timing of when interest is paid out and compounded. For instance, interest on a savings account may be paid monthly but compounded daily. The account balance plus any interest that has accrued but has not yet been paid out are used by the bank to determine your daily interest earnings.

For the above question:

Account Balance = Principal x (1 + interest rate (decimal))^number of the years. With given information this is:  [tex]2000 (1.03)^2[/tex] = 2,121.80.  So we will earn 121.80 in interest after the 2 years on your original 2000 deposit.

Answer: the x value of the ordered pair is 0

Acceleration of the ball is 10 [tex]m/s^{2}[/tex].

The relation between initial velocity , final velocity , acceleration and time can be written as,

v = u + at

Here, v is the final velocity, u is the initial velocity, a is the acceleration and t is the time

Time taken by ball to reach the ground = t = 2 seconds.

As it starts from rest , initial velocity of ball = u = 0 m/s.

Final velocity of ball = v = 20m/s.

v = u + at                                                               equation 1

Put value of v = 20m/s , u = 0m/s and t = 2 seconds in equation 1.

(20m/s) = (0 m/s) + a (2 second)

a = ( 20m/s )/( 2second )

a = 10 [tex]m/s^{2}[/tex]

Acceleration of the ball is 10 [tex]m/s^{2}[/tex].

Answer:

LK = 7

Step-by-step explanation:

We are using segment addition

NM + ML + LK = NK

x-6  + 9 +  2x-19  = 23

Combine like terms

x+2x   -6+9-19 = 23

3x -16 = 23

Add 16 to each side

3x-16+16 = 23+16

3x = 39

Divide each side by 3

3x/3 = 39/3

x = 13

We want to find the value of LK

LK = 2x-19

     =2(13) -19

     = 26 -19

    = 7

Answer:

[tex]\sf \: LK = 7 \: units[/tex]

Step-by-step explanation:

It's clear that,

[tex] \sf \: NM + ML + LK = NK[/tex]

Given that,

NM ---> x - 6

ML ---> 9

LK ---> 2x - 19

NK ---> 23

First, let us find the value of x using these values.

[tex] \sf \: NM + ML + LK = NK \\ \sf x - 6 + 9 + 2x - 19 = 23 \\ \sf \: combine \: like \: terms. \\ \sf \: 3x - 16 = 23 \\ \sf3x = 23 + 16 \\ \sf3x = 39 \\ \sf \: divide \: both \: sides \: by \: 3. \\ \sf \: x = 13[/tex]

And now we have to find out the length of LK.

As we mentioned before,

LK = 2x - 19

So, to find the length of LK, we have to replace x with 13 and solve the equation.

Let us solve now.

[tex] \sf \: LK = 2x - 19 \\ \sf \: LK = 2 \times 13 - 19 \\ \sf \: LK = 26- 19 \\ \sf \: LK = 7 \: units[/tex]

The central limit theorem (CLT) of probability theory states that, under the assumption that all samples are of equal size and regardless of the population's actual distribution shape, the distribution of a sample variable approaches a normal distribution (i.e., a "bell curve") as the sample size increases.

The density of the sample is 796.61 kg/m^3.

According to teh given question.

The weight of the metal is 18.5g

The volume of the sample is 2.36 cm^3 or 0.00000236

Since, we know that

Weight = mass × acceleration due to gravity

⇒ 18.5g = mass of the metal × 9.8

⇒ 18.5g/1000 = mass of the metal × 9.8

⇒ mass of the metal = 0.00188kg

Therefore,

the density of the sample

= 0.00188/0.00000236

= 796.61 kg/m^3

Hence, the density of the sample is 796.61 kg/m^3.

Primero, debemos encontrar las soluciones a la ecuación:

2x^2 - 6x + (9/2) = 0

Esto nos dara los interceptos con el eje x.

Usando la formula de Bhaskara obtendremos:

x = ( 6 ± √( (-6)^2 - 4*(9/2)*2 )/(2*2)

x = (6  ± 0)/4

Now, putting these values into the slope-point form equation, We get :

            => (y - y₁) = m(x - x₁)

            => (y - (-8) = 4(x - 1)  => (y +8) = 4x -4

            => y = 4x -12          ---> Equation (1)

We got the slope-intercept form for the following situation.

We can find out the y-intercept value by comparing the
