Given m||n, find the value of x.

Answer:

0.3

Step-by-step explanation:

To solve this, I asked, "If 7 divided by 21 is 3, then 7 divided by 22 would have little to no difference in the tenths place, right?" And that question is correct. Answering this question, the decimal place could not be greater than 5, because 7/22 is the formula for another, more accurate, albeit shorter version of pi, but backwards. 7/22 is 0.31, and 0.31's tenths place has a 1 in it, so this, according to the laws of rounding, rounds downward. Therefore, the correct answer would be 0.3.

Hope this helps!

The entropy of X (number of defective chips) in bits is a measure of uncertainty about the value of X.

The entropy of a random variable represents the amount of uncertainty or randomness associated with the outcome of the variable. To calculate the entropy of a discrete random variable, we need to determine the probability distribution function and use the formula:

H(X) = -Σ P(X=x) log2(P(X=x))

In this case, the random variable X represents the number of defective chips in 5 randomly chosen chips from a box of 50, with 3 defective chips. The possible outcomes are 0, 1, 2, 3, and 4, with probabilities:

P(X=0) = (47/50)^5

P(X=1) = (5 * (3/50) * (47/50)^4)

P(X=2) = (10 * (3/50)^2 * (47/50)^3) / 2!

P(X=3) = (5 * (3/50)^3 * (47/50)^2) / 3!

P(X=4) = (3/50)^4 / 4!

By plugging in the probabilities into the entropy formula, we can find the entropy in bits.

Answer:

The function is translated down 2 and and to the right 3

Step-by-step explanation:

[tex]f(x)=(x-h)+k[/tex]

h = transition left or right

k = transition up or down

Answer: No, it is not proportional.

Step-by-step explanation: X will be the mystery number here. So first, we want to find a common denominator. 5 times x equals 20. We want to divide 20 by 5. 20/5 equals 4. X = 4. So now we want to multiply the 4 from 4/5 by 4. 4 times 4 equals 16.

4/5 = 16/20

A formula for the function g(x) obtained when the graph of f(x) = 1/x is shifted down 7 units and to the right 5 units is g(x) = 1/(x - 5) - 7.

In Mathematics, the translation a geometric figure or graph to the right simply means adding a digit to the value on the x-coordinate of the pre-image or function.

In Mathematics, a horizontal translation to the right is modeled by this mathematical expression g(x) = f(x - N) while a vertical translation to the negative y-direction (downward) is modeled by this mathematical expression g(x) = f(x) - N.

Where:

By translating the graph of f(x) = 1/x down 7 units and 5 units to the right , we have:

g(x) = f(x - 5) - 7

g(x) = 1/(x - 5) - 7

The Marginal Revenue MR(29) 11513 dollars per unit.

The velocity is v(t) = 24t² - 96t - 120.

The velocity equals zero at t = 5.

The acceleration of the particle is a(t) = 48t - 96.

Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.

Suppose a product's revenue function is given by R(q) = -7q² + 600q,

where R(q) is in dollars and q is units sold.

We have to determine a numeric value for the marginal revenue at 29 units

As per the question we have

R(q) = -7q² + 600q

Substitute the value of q = 29, and we get

R(29) = -7(29)² + 600(29)

R(29) = 11513

Thus, the Marginal Revenue MR(29) 11513 dollars per unit

Let s(t) = 8t³ - 48t² - 120t be the equation of motion for a particle.

To find the velocity, we need to differentiate the equation for the position of the particle, s(t).

v(t) = ds/dt = d/dt (8t³ - 48t² - 120t) = 24t² - 96t - 120

To find the t-values where the velocity is equal to zero, we need to set v(t) equal to zero and solve for t.

0 = 24t² - 96t - 120

This is a quadratic equation, and we can solve for t by factoring the GCF

(t - 5)(t + 1) = 0

(t - 5) = 0 and (t + 1) = 0

t = 5 and t = -1

So the velocity equals zero at t = 5

To find the acceleration, we need to differentiate the velocity function, v(t).

a(t) = dv/dt = d/dt (24t² - 96t - 120) = 48t - 96

So the acceleration of the particle is a(t) = 48t - 96.

The correct order of the assumptions used in the derivation is: A, B, C, D, E. A states that the population is large, B: random, C: representative, D: large, and E states that the sampling is done without replacement.

The derivation of the Central Limit Theorem was based on five assumptions: (a) The population is large, (b) The sample is random, (c) The sample is representative, (d) The sample size is large, and (e) The sampling is done without replacement. The first assumption used in the derivation is that the population is large, which means that the number of individuals in the population is much greater than the sample size. This is important because the Central Limit Theorem states that the mean of the sample will approach the population mean as the sample size increases. The second assumption used is that the sample is random, which means that each individual in the population has an equal chance of being selected for the sample. This helps to ensure that the sample is representative of the population as a whole. The third assumption is that the sample is representative, which means that the characteristics of the sample are similar to those of the population. This is important because it allows us to make generalizations about the population based on the sample. The fourth assumption is that the sample size is large. This is important because the Central Limit Theorem states that the mean of the sample will approach the population mean as the sample size increases.

The length, in units, of the rectangle is 9 units.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Length = x

Width = x - 8

Area = 9 square units

Now,

The area of the rectangle = length x width

9 = x (x - 8)

9 = x² - 8x

x² - 8x - 9 = 0

Solve for x.

x² - 8x - 9 = 0

x² - (9 - 1)x - 9 = 0

x² - 9x + x - 9 = 0

x(x - 9) + 1(x - 9) = 0

(x - 9) (x + 1) = 0

x - 9 =0 and x + 1 = 0

Principal amount in each account is $200 for Account A and $600 for Account B. Simple interest is most earned for Account B.

Simple interest is defined as the interest obtained over the principal amount on a certain rate.

Simple interest is calculated by the formula,

SI = P × r × t,

where P is the principal amount, r is the interest rate and t is the time in years.

Account A :

t = 6 months = 0.5 year

S.I = $3.30

r = 3.3% = 0.033

Substituting in the formula,

3.30 = P × 0.033 × 0.5

P = 200

Principal amount in Account A is $200.

Simple interest earned in the first month = 200 × 0.033 × (1/12) = $0.55

Account B :

t = 30 months = 2.5 years

S.I = $37.50

r =  2.5% = 0.025

Substituting in the formula,

37.50 = P × 0.025 × 2.5

P = 600

Principal amount in Account B is $600.

Simple interest earned in the first month = 600 × 0.025 × (1/12) = $1.25

Account B earned more interest in the first month.

Hence Account B earned most interest in the first month with am amount of $1.25.

Answer:

width of the flag is 440 feet and the length is 780 feet

Step-by-step explanation:

Let's call the width of the flag "w". Then the length of the flag can be represented as "w + 340".

The perimeter of the flag is the sum of all four sides, so we can write the following equation:

2w + 2(w + 340) = 2,440

Expanding the second term on the left side and simplifying:

2w + 2w + 680 = 2,440

4w + 680 = 2,440

Subtracting 680 from both sides:

4w = 1,760

Dividing both sides by 4:

w = 440

So the width of the flag is 440 feet and the length is 780 feet (440 + 340).

The vertex form of a quadratic function is f(x) = a(x – h)² + k, where a, h, and k are constants of the parabola is at (h, k).

Given:

y =1/30 x²-2x+1530

y= 1/30 x² - 2x + 1530

comparing the above equation with y ax²+ bx +c we get

a = 1/30

b = -2

c = 1530

Now, the the x coordinate of the vertex

h = -b/(2a)

h = -(-2)/(2x(1/30))

h = 2/(2/30)

h = (2/1) x (30/2)

h = (2 x 30)/(1 x 2)

h = 60/2

h = 30

So, The x coordinate of the vertex is 30.

Now, we plug in x = 30 to find the y coordinate of the vertex.

y =1/30 x²-2x+1530

y =1/30 (30)²-2(30)+1530

y =1/30 (900)-60+1530
