Answer:

36 < (x - 2)² + (y + 3)² and 16 > (x - 4)² + y²

Step-by-step explanation:

This is because the shaded area is inside the first circle (centered at (4, 0) with a radius of 4) but outside the second circle (centered at (2, -3) with a radius of 6). The inequalities reflect these conditions by setting the inequality signs accordingly. The inequality with "<" for the first circle ensures that the shaded area is within the circle, and the inequality with ">" for the second circle ensures that the shaded area is outside the circle.

The equation can be written as a linear combination of the vectors in S:

z = 5*(1, 2, −2) -1*(2, −1, 1)

v = -2*(1, 2, −2) + 7*(2, −1, 1)

w = -12*(1, 2, −2) + 11*(2, −1, 1)

What is the linear combination?

Linear combination is the process of adding two algebraic equations so that one of the variables is eliminated. Addition or subtraction can be used to perform a linear combination.

(a) z = (−3, −1, 1)

We can write z as a linear combination of the vectors in S by using the following equation:

z = as1 + bs2

Here, we can find the values of a and b by solving the following system of equations:

-3 = a1 + b2

-1 = a2 + b(-1)

1 = a*(-2) + b*1

Solving this system of equations, we get:

a = 5

b = -1

Therefore, z can be written as a linear combination of the vectors in S as:

z = 5*(1, 2, −2) -1*(2, −1, 1)

(b) v = (−2, −5, 5)

we can write v as a linear combination of the vectors in S by using the following equation:

v = as1 + bs2

Here, we can find the values of a and b by solving the following system of equations:

-2 = a1 + b2

-5 = a2 + b(-1)

5 = a*(-2) + b*1

Solving this system of equations, we get:

a = -2

b = 7

Therefore, v can be written as a linear combination of the vectors in S as:

v = -2*(1, 2, −2) + 7*(2, −1, 1)

(c) w = (1, −23, 23)

we can write w as a linear combination of the vectors in S by using the following equation:

w = as1 + bs2

Here, we can find the values of a and b by solving the following system of equations:

1 = a1 + b2

-23 = a2 + b(-1)

23 = a*(-2) + b*1

Solving this system of equations, we get:

a = -12

b = 11

Therefore, w can be written as a linear combination of the vectors in S as:

w = -12*(1, 2, −2) + 11*(2, −1, 1)

Therefore, The equation can be written as a linear combination of the vectors in S:

z = 5*(1, 2, −2) -1*(2, −1, 1)

v = -2*(1, 2, −2) + 7*(2, −1, 1)

w = -12*(1, 2, −2) + 11*(2, −1, 1)

The median will be greater than the mean in a left-skewed distribution

We have,

In statistics, skewness is a measure of the asymmetry of a probability distribution around its mean.

A distribution is said to be skewed left if it has a long tail on the left side and the bulk of the data is on the right side.

When the data is skewed left, it means that the distribution is being pulled towards the left side.

This is because there are a few extreme values on the left side that are pulling the mean in that direction.

In contrast, the median is the middle value of the dataset, and it is not influenced by outliers.

For a left-skewed distribution,

The median will be greater than the mean because the mean is being pulled towards the left by the few extreme values.

In a data distribution that is skewed left, the mean will be less than the median.

This is because the mean is sensitive to outliers and is pulled towards the direction of the skewness, while the median is not affected by extreme values and is a more robust measure of central tendency.

Therefore,

The critical value, given the sample size of 5 and the confidence level of 99. 0 percent would be 16. 812.

The critical values for the chi-squared (χ^2) distribution depend on the degree of freedom and the level of significance.

The degree of freedom for a chi-squared distribution typically equals the sample size minus 1 so the degrees of freedom here is:

= 5 - 1

= 4

The level of significance would be:

= 1 - 99. 0 %

Answer:

The total fare is $53, and the distance is 25

Step-by-step explanation:

The equation we can use for the first car would be:

The relationship between logarithms and exponential functions is fundamental and provides a powerful tool for finding solutions in various mathematical and scientific contexts.

Logarithms are the inverse functions of exponential functions. They allow us to solve equations and manipulate exponential expressions in a more manageable way. By taking the logarithm of both sides of an exponential equation, we can convert it into a linear equation, which is often easier to solve.

One of the key properties of logarithms is the ability to condense multiplication and division operations into addition and subtraction operations. For example, the logarithm of a product is equal to the sum of the logarithms, and the logarithm of a quotient is equal to the difference of the logarithms.

Logarithms also help us solve equations involving exponential growth or decay. By taking the logarithm of both sides of an exponential growth or decay equation, we can isolate the exponent and solve for the unknown variable.

This is particularly useful in fields such as finance, population modeling, and radioactive decay, where exponential functions are commonly used.

Furthermore, logarithms provide a way to express very large or very small numbers in a more manageable form. The logarithmic scale allows us to compress a wide range of values into a smaller range, making it easier to analyze and compare data.

In summary, the relationship between logarithms and exponential functions enables us to simplify and solve equations involving exponential expressions, model exponential growth or decay, and manipulate large or small numbers more effectively.

The probability that number of students in favor of increment in fees : p = 0.70

Number of students follows Binomial distribution

(a) We have to find the probability that 2 or fewer in the sample will favor the project

P( x ≤ 2) = P(0) + P(1) + P(2)

As we know ,

P(x) = ⁿCₓpˣq⁽ⁿ⁻ˣ⁾

=> P( x ≤ 2) = ¹²C₀p⁰q¹² + ¹²C₁p¹q¹¹ + ¹²C₂p²q¹⁰

Answer:

The arc-length is about 1.1953.

Step-by-step explanation:

We are given the equation:

\(y=3-x^2\)

And we want to find the length of its arc from:

\(0\leq x\leq \sqrt3/2\)

Recall that arc-length is given by the formula:

\(\displaystyle S = \int_a^b \sqrt{1+ \left(\frac{dy}{dx}\right)^2}\, dx\)

By differentiating and substituting into the arc-length formula, we will acquire:

\(\displaystyle S=\int\limits^{\sqrt{3}/2}_0 {\sqrt{1+4x^2} \, dx\)

To evaluate, we can use trigonometric substitution. Note that:

\(\displaystyle S=\int\limits^\sqrt3/2}_0 {\sqrt{(1)^2+(2x)^2} \, dx\)

Since this is in the form a² + u², we will make the substitution u = atan(θ).

In this case, a = 1 and u = 2x. Thus:

\(\displaystyle 2x = \tan \theta\)

Differentiating both sides with respect to x:

\(\displaystyle 2\, dx = \sec^2 \theta \, d\theta\)

So:

\(\displaystyle dx = \frac{1}{2}\sec^2 \theta \, d\theta\)

Additionally, we must rewrite our bounds. Hence:

\(\displaystyle 2(0) = \tan \theta \Rightarrow \theta = 0\)

And:

\(\displaystyle 2\left(\frac{\sqrt{3}}{2}\right) = \tan\theta \Rightarrow \theta = \frac{\pi}{3}\)

Thus:

\(\displaystyle S = \int_{0}^{\pi /3}\sqrt{1+(\tan\theta)^2}\cdot \frac{1}{2}\sec^2\theta\, d\theta\)

Simplify:

\(\displaystyle S = \frac{1}{2}\int_{0}^{\pi /3}\sqrt{1+\tan^2\theta} \cdot \sec^2\theta d\theta\)

Using trigonometric identities:

\(\displaystyle S = \frac{1}{2}\int_{0}^{\pi /3}\sqrt{(\sec^2\theta)} \cdot \sec^2\theta d\theta\)

Simplify:

\(\displaystyle S = \frac{1}{2}\int_{0}^{\pi /3} \sec^3\theta \, d\theta\)

We can apply the reduction formula:

\(\displaystyle \int \sec^nu \, du = \frac{\sec^{n-2}u\tan u}{n-1}+\frac{n-2}{n-1}\int \sec^{n-2} u \, du\)

Hence:

\(\displaystyle S = \frac{1}{2}\left(\frac{\sec \theta \tan\theta}{2}\Big|_{0}^{\pi /3} + \frac{1}{2} \int_0^{\pi /3} \sec \theta\, d\theta\right)\)

This is a common integral:

\(\displaystyle S = \frac{1}{2}\left(\frac{\sec \theta \tan\theta}{2}+ \frac{1}{2} \left(\ln \left(\sec \theta + \tan\theta\right)\right)\Bigg|_{0}^{\pi /3} \right)\)

Evaluate. Hence:

\(\displaystyle \begin{aligned} S = \frac{1}{2}\left[\left(\frac{\sec\dfrac{\pi}{3}\tan\dfrac{\pi}{3}}{2}+\frac{1}{2}\ln\left(\sec\dfrac{\pi}{3}+\tan\dfrac{\pi}{3}\right)\right) \\ - \left(\frac{\sec0\tan0}{2}+\frac{1}{2}\ln\left(\sec 0 +\tan 0\right)\right)\right] \end{aligned}\)

Evaluate:

\(\displaystyle \begin{aligned} S &=\frac{1}{2} \left[ \left(\frac{(2)\left(\sqrt{3}\right)}{2} + \frac{1}{2}\ln \left(2 + \sqrt{3}\right) \right)-\left(\frac{(1)(0)}{2} + \frac{1}{2}\ln \left(1+0\right) \right) \right] \\ \\&= \frac{1}{2}\left(\sqrt{3} + \frac{1}{2} \ln \left(2+\sqrt{3}\right)\right) \\ \\ &\approx 1.1953 \end{aligned}\)

Thus, the length of the arc is about 1.1953 units.
