Answer:

\(\Huge \bold{\boxed{\boxed{\text{5\%}}}}\)

Step-by-step explanation:

To calculate the margin of error for the survey, we need to use the formula:

\(\large \text{Margin of error} = \large \text{$\frac{\text{Range of values}}{2}$}\)

The range of values is the difference between the upper and lower bounds of the interval. In this case, the lower bound is 22% and the upper bound is 32%, so the range of values is:

\(\large \text{Range of values = 32\% - 22\% = 10\%}\)

Substituting this value into the formula, we get:

\(\large \text{Margin of error = $\frac{10\%}{2}$ = 5\%}\)

Therefore, the margin of error on the survey is 5%.

The Total Probability of getting exactly two 3s in two throws is 1/36

What is Probability?

A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.

Solution:

Probability of Obtaining 3 in the first throw = 1/6

Since, the number of possible outcome is 11 and total outcomes are 6

Similarly the probability of getting 3 in the second throw is 1/6

Therefore, total probability = 1/6 * 1/6 = 1/36

Answer:

25%

Step-by-step explanation:

First convert 3 hours into minutes by multiplying 3 x 60 min/hr. This is 180 minutes. To find the percentage, divide 45 minutes by 180 minutes and then multiply by 100.

45/180=0.25x100 = 25%

The time 45 minutes is 75 percentage of 3 hours

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the percentage be represented as A

Now , the equation will be

The time be represented as p = 45 minutes

The value of p = 3/4 hours

The value of q = 3 hours

So , the percentage is A = ( p/q ) x 100

Substituting the values in the equation , we get

The percentage A = ( 3/4 ) / 3 x 100

On simplifying the equation , we get

The percentage A = ( 3/12 ) x 100

The percentage A = ( 1/4 ) x 100

The percentage A = 25 %

Hence , the percentage is 25 %

If you have previous taxable wages of $102,000 and your current taxable wages are $1,100, your Social Security tax would be $6,324 for the previous wages and $68.20 for the current wages.

To calculate the Social Security tax, we need to know the tax rate for Social Security and the taxable wages. Let's assume the Social Security tax rate is 6.2% for both the employee and the employer.

Given that your taxable wages for Social Security purposes are $1,100, and your previous taxable wages are $102,000, we can determine the Social Security tax amount.

First, we need to calculate the Social Security tax on the previous taxable wages of $102,000. Multiply $102,000 by 6.2% (0.062) to find the Social Security tax for that amount:

Social Security tax = $102,000 x 0.062 = $6,324

Next, we calculate the Social Security tax on the current taxable wages of $1,100. Multiply $1,100 by 6.2% to find the tax amount:

Social Security tax = $1,100 x 0.062 = $68.20

Therefore, if you have previous taxable wages of $102,000 and your current taxable wages are $1,100, your Social Security tax would be $6,324 for the previous wages and $68.20 for the current wages.

Step-by-step explanation:

it seems you solved the tricky part yourself already.

just to be sure, let's do the first derivative here again.

the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...

f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =

= 3t⁴ + 18t³ + 24t² + 18t + 21

f'(t) = 12t³ + 54t² + 48t + 18

and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).

we simply put the input number (2) at every place of the input variable (t).

so,

f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =

= 426

Answer:

100x2/3-3x/3-6

Step-by-step explanation:

Step-by-step explanation:

f(x) = ln(1+2x), a = 5, n = 3

Find the derivatives.

f⁽⁰⁾(5) = ln(1+2(5)) = ln(11)

f⁽¹⁾(5) = 2 / (1+2(5)) = 2/11

f⁽²⁾(5) = -4 / (1 + 2(5))² = -4/121

f⁽³⁾(5) = 16 / (1 + 2(5))³ = 16/1331

T₃(x) = ln(11) (x − 5)⁰ / 0! + 2/11 (x − 5)¹ / 1! − 4/121 (x − 5)² / 2! + 16/1331 (x − 5)³ / 3!

T₃(x) = ln(11) + 2/11 (x − 5) − 2/121 (x − 5)² − 8/3993 (x − 5)³

Find the fourth derivative.

f⁽⁴⁾(x) = -96 / (1 + 2x)⁴

So the next term of the series would be:

(-96 / (1 + 2x)⁴) (x − 5)⁴ / 4!

For 4.6 ≤ x ≤ 5.4,│f⁽⁴⁾(x)│is a maximum at x = 4.6.  Therefore:

│R₃(x)│≤ │(-96 / (1 + 2(4.6))⁴) (4.6 − 5)⁴ / 4!│

│R₃(x)│≤ 0.000009

│R₃(x)│is always positive, so we can ignore the right two graphs.  Only the top left graph is less than 9×10⁻⁶ on the interval.

Multiplying both sides by \(y^2\) gives

\(xy^2\dfrac{\mathrm dy}{\mathrm dx}+y^3=1\)

so that substituting \(v=y^3\) and hence \(\frac{\mathrm dv}{\mathrm dv}=3y^2\frac{\mathrm dy}{\mathrm dx}\) gives the linear ODE,

\(\dfrac x3\dfrac{\mathrm dv}{\mathrm dx}+v=1\)

Now multiply both sides by \(3x^2\) to get

\(x^3\dfrac{\mathrm dv}{\mathrm dx}+3x^2v=3x^2\)

so that the left side condenses into the derivative of a product.

\(\dfrac{\mathrm d}{\mathrm dx}[x^3v]=3x^2\)

Integrate both sides, then solve for \(v\), then for \(y\):

\(x^3v=\displaystyle\int3x^2\,\mathrm dx\)

\(x^3v=x^3+C\)

\(v=1+\dfrac C{x^3}\)

\(y^3=1+\dfrac C{x^3}\)

\(\boxed{y=\sqrt[3]{1+\dfrac C{x^3}}}\)

The cumulative distribution function of a real-valued random variable X, or simply the distribution function of X, assessed at x, is the likelihood that X will have a value less than or equal to x in probability theory and statistics.

Using the Cumulative Distribution Function to Calculate Probabilities

F(x) is a cumulative distribution function that calculates the likelihood that the random variable X is smaller than or equal to x:

To get the cumulative probability that X is less than or equal to 1, multiply P(X=0) by P(X = 0) by (P=1):

First, we will determine the value of the cumulative probability P(X<=x):

x         f(x)       P(X<=x)

The period of the sound wave created by the tuba is approximately 0.0134 seconds.

The speed of sound in air is given as 343 meters per second. The formula relating the speed of sound, wavelength, and period of a wave is:

v = λ × f

Where:

v = speed of sound (343 m/s)

λ = wavelength (4.61 m)

f = frequency (unknown)

To find the period, we need to determine the frequency of the sound wave. The period (T) is the reciprocal of the frequency (f), so we can rewrite the formula as:

v = λ / T

Rearranging the equation to solve for the period (T), we get:

T = λ / v

Substituting the given values, we have:

T = 4.61 m / 343 m/s

Calculating the value, we find:

T ≈ 0.0134 seconds

Therefore, the period of the sound wave created by the tuba is approximately 0.0134 seconds.
