Nine less than two times a number is five more than this number. What is the number?

Answer:

235.5

Step-by-step explanation:

cylinder volume formula

V = pi * r^2 * h

V = 3.14 * 5^2 * 3

V = 3.14 * 25 * 3

V = 3.14 * 75

V = 235.5

Answer:

  17.86

Step-by-step explanation:

You want to find y when x=8 using the equation y = 13.06 +0.6x.

Put the value of the variable in place of the variable in the equation, and do the arithmetic.

  y = 13.06 +0.6x

  y = 13.06 +0.6·8 . . . for x=8

  y = 13.06 +4.8

  y = 17.86

The estimated value of y for x=8 is 17.86.

The required compatible number of the given two number are 500 and 200 and sum is 700.

In math, compatible numbers are the numbers that are not difficult to add, deduct, duplicate, or gap intellectually. compatible number  are close in worth to the real numbers that make assessing the response and figuring issues more straightforward. We can adjust the numbers to the closest ten, hundred, thousand or 10,000 to make them viable numbers. For example, in the event that we need to add 493 and 549, we can make the numbers viable by gathering them together to the closest tens or hundreds. 490 and 550 (adjusted to the closest tens) or 500 and 500 (adjusted to the closest hundreds) are a lot simpler to settle.

So, the compatible number of 455 is 500 and that of 225 is 200.

Then,

Compatible sum = 500 + 200 = 700.

The next three numbers that would be generated are 13, 37, and 109.

Formula is a mathematical expression that is used to calculate the value of a particular quantity, such as a number, a quantity of a certain type of material, or a number of elements. The most common form of a formula is an equation, which contains two or more variables and is written in the form of a mathematical expression. Formulas are used in many disciplines, including physics, chemistry, engineering, and economics, to solve problems and determine relationships between quantities.
This is because the formula applies the operation of multiplying the current number by 3 and then subtracting 2. Applying this formula to 5 gives 13, and then applying the formula to 13 gives 37, and so on. The resulting sequence is 5, 13, 37, 109, and so on. This is a simple PRNG that can be used to generate sequences of random numbers.

Step-by-step explanation:

Define a sequence of random variables B, Does the sequence of random variables Bre n converge in probability to a constant b? If yes, enter the value of b below, if no, enter "DNE". (Enter e for the constant e)

B6- As above, let a be the limit in probability of An, ie. An a, and b be the limit in probabiity of Bn = 4, i.e. Br*b, if these limits exist.

The correct characterization of the limit distribution and other Questions are answered in the following steps.

For the first question, the distribution of (An-a) is approximated best by N(0, n) because the variance of the sample mean of i.i.d. standard normal variables is 1/n.

For the second question, since An converges in probability to a constant, Bn = 4An also converges in probability to 4a. Therefore, the sequence of random variables (Bn-b) does converge in distribution.

For the third question, the limit distribution of (Bn-b) is N(0, 4^2 * n) because the variance of the product of a random variable and a constant is the constant squared times the variance of the random variable.

After solving the equation, the number of hours obtained is that after 2 hours, the cost ends up being the same for either artist.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given information in the question,

Booking fee of Martha = $10

Additional hourly charge of Martha = $40

Then, the equation will be,

y = $10 + $40x            (i)

Here, y is the total cost and x is the number of hours.

Booking fee of Jackie = $20

Additional hourly charge of Jackie = $35

Then, the equation for this will be,

y = $20 + $35x           (ii)

Here, y is the total cost and x is the number of hours.

Then, depending on the length of the show, the cost could end up being the same for either artist.

So,

From equations (i) and (ii)

$20 + $35x =  $10 + $40x

Step-by-step explanation:

To solve an equation for a variable, you can isolate the variable by performing operations that eliminate all other terms.

In this case, the given equation is 2x^2/y = w + 2/4. To solve for w, you can first eliminate the 2/4 term on the right-hand side by multiplying both sides of the equation by 4/2:

4 * (2x^2/y) = 4 * (w + 2/4)

4 * 2x^2/y = 4w + 4 * 2/4

8x^2/y = 4w + 2

Then, you can subtract 2 from both sides to eliminate the 2 on the right-hand side:

8x^2/y - 2 = 4w + 2 - 2

8x^2/y - 2 = 4w

Finally, you can divide both sides of the equation by 4 to eliminate the 4 on the right-hand side:

(8x^2/y - 2) / 4 = (4w) / 4

w = 8x^2/7 - 2

Therefore, the correct answer is w = 8 x squared minus 2 y Over y. This is an equivalent equation to find w, as it gives the same value for w as the original equation when the same values are used for x and y.

The other equations given are not equivalent to the original equation for finding w.

The affect of mean and median due to the birth of the 4th kitchen is B. Both the mean and median will increase, but the mean will increase by more than the median.

The median is the middle value when the values are ordered from smallest to largest. In this case, the median of the first 3 kittens is 153 because it is the middle value of (147, 153, 159). The median of all 4 kittens is 153 because it is the middle value of (57, 147, 153, 159). The median does not change because the addition of the 4th kitten does not change the position of the middle value.

The mean is calculated by adding up all the values and dividing by the number of values. In this case, the mean of the first 3 kittens is:

(147 + 153 + 159) / 3 = 153

The mean of all 4 kittens is:

(147 + 153 + 159 + 57) / 4 = 128

The mean increases because the addition of the 4th kitten with a lower mass pulls the overall average down.
