Given an arithmetic sequence with a common difference of 3 and the tenth term being 11, we can find the sum of the first 30 terms. The sum is 810.

In an arithmetic sequence, each term is obtained by adding a constant value, called the common difference, to the previous term. Let's denote the first term of the sequence as 'a' and the common difference as 'd'.

Given that the tenth term is 11 and the common difference is 3, we can use this information to find the first term. We know that the tenth term is obtained by adding the common difference 9 times to the first term:

a + 9d = 11

Substituting the value of the common difference (d = 3), we can solve for 'a':

a + 9(3) = 11

a + 27 = 11

a = 11 - 27

a = -16

Now that we have the first term 'a' and the common difference 'd', we can find the sum of the first 30 terms using the formula for the sum of an arithmetic series:

S = (n/2)(2a + (n-1)d)

Here, 'n' represents the number of terms. Substituting the values, we have:

S = (30/2)(2(-16) + (30-1)(3))

S = 15(-32 + 29(3))

S = 15(-32 + 87)

S = 15(55)

S = 825

Therefore, the sum of the first 30 terms of the given arithmetic sequence is 810.

A mean of a normal distribution's upper bound of a 95% confidence interval is 58.11.

For the given question,

The confidence bound's upper limit (UCB) is determined as follows:

UCB =  μ + z(α/2)×σ/√n

Now, α/2 = (1 - 0.95)/2

α/2 = 0.025

z(α/2) = 1.96  (obtain from t-distribution table for degree of freedom)

Put the values in the formula,

UCB =  μ + z(α/2)×σ/√n

UCB = 36.96 + 1.96×41.8/√15

UCB = 58.11

As a result, 58.11 is the upper bound of a 95% confidence interval for the mean of a normal distribution.

The maximum possible value of |f(1.2) - T3(1.2)|, where T3 is the Maclaurin polynomial of f(x) = eˣ , is approximately 0.000382, as found using the Error Bound formula with M = \(e^1.2\) and n = 3.

The Maclaurin polynomial of degree 3 for the function f(x) = eˣ is:

T3(x) = 1 + x + (x²)/2 + (x³)/6

To find the maximum possible value of |f(1.2) - T3(1.2)|, we need to use the Error Bound formula, which states that for a given function f(x) and its Maclaurin polynomial Tn(x), the error E(x) in approximating f(x) with Tn(x) is given by:

|E(x)| ≤ (M x |x\(^(n+1)\)|) / (n+1)!

where M is the maximum value of the (n+1)th derivative of f(x) on the interval [0, x].

In this case, we have:

f(x) =eˣ

T3(x) = 1 + x + (x²)/2 + (x³)/6

n = 3

x = 1.2

We need to find the maximum possible value of |f(1.2) - T3(1.2)|, so we need to find M, the maximum value of the 4th derivative of f(x) on the interval [0, 1.2].

The 4th derivative of f(x) is f''''(x) = eˣ , which is increasing on the interval [0, 1.2], so the maximum value of eˣ  on this interval is e^1.2.

Therefore, we have:

M = e^1.2

Plugging in the values for n, x, and M in the Error Bound formula, we get:

|E(1.2)| ≤ (\(e^1.2\) x |1.2⁴|) / 4!

         ≈ 0.000382

Therefore, the maximum possible value of |f(1.2) - T3(1.2)| is approximately 0.000382.

So we can write:

|f(1.2) - T3(1.2)| ≤ 0.000382

Note that this is an upper bound on the error, so the actual error could be smaller than this.

Answer:

To solve the expression, we substitute the given values of x and y into the expression and perform the calculations.

Given: x = 7, y = 2

Expression: (y + 2) * (x + 4 - 5)

Substituting the values:

(2 + 2) * (7 + 4 - 5)

Performing the calculations:

4 * (7 + 4 - 5)

4 * (11 - 5)

4 * 6

24

Therefore, when x = 7 and y = 2, the value of the expression (y + 2) * (x + 4 - 5) is 24.

Answer:

24

Step-by-step explanation:

we are putting 7 in for x and 2 in for y so the equation becomes

(2+2) times (7+4-5) which equals 24

To evaluate the function f(x) = 3x + 8 for a specific value of x, we can substitute the value into the function and perform the necessary calculations. In this case, when evaluating f(-4), we substitute -4 into the function to find the corresponding output. The result is f(-4) = 3(-4) + 8 = -12 + 8 = -4.



The function f(x) = 3x + 8 represents a linear equation in the form of y = mx + b, where m is the coefficient of x (in this case, 3) and b is the y-intercept (in this case, 8). To evaluate f(-4), we substitute -4 for x in the function and calculate the result.

Replacing x with -4 in the function, we have f(-4) = 3(-4) + 8. First, we multiply -4 by 3, which gives us -12. Then, we add 8 to -12 to get the final result of -4. Therefore, f(-4) = -4. This means that when x is -4, the function f(x) evaluates to -4.

The value of the line integral ∫_c F · dr is zero for any curve c on s.

Since = ∇ , we know that the vector field is a gradient field, which means that it is conservative. By the fundamental theorem of calculus for line integrals, the line integral ∫_c F · dr over any closed curve c in the domain of F is zero, where F is the vector field and dr is the differential element of arc length along the curve c.

Since s is a level surface of f, we know that f is constant on s. Therefore, any curve on s is also a level curve of f, and the tangent vector to c is perpendicular to the gradient vector of f at every point on c. This means that F · dr = 0 along c, since the dot product of two perpendicular vectors is zero.

Therefore, the value of the line integral ∫_c F · dr is zero for any curve c on s.

Step-by-step explanation:

Solving (a): 5060 as a power of 10

We simply move the decimal between 5 and 6. The number of zeros to move backward is 4.

So,

\(5 0 6 0 = 5.06 * 10^3\)

Solving (b): 6079000 as a power of 10

We simply move the decimal between 6 and 0. The number of zeros to move backward is 4.

Solving (c): 3 crore to millions

\(1\ crore = 10\ million\)

Multiply by 3

\(3\ crore = 30\ million\)

Solving (d): The greatest 6 digits

The greatest unit digit is 9. So, we simply write out 9 in 6 places

In this case, the car's velocity is given as 160 km/h, which needs to be converted to m/s before substituting it into the formula. The radius of the race course is provided as 700 m. Plugging these values into the formula, we can calculate the centripetal acceleration experienced by the car.

To find the centripetal acceleration, we first convert the car's velocity from km/h to m/s. We know that 1 km/h is equal to 0.2778 m/s, so 160 km/h is equal to 44.44 m/s. Next, we substitute the values into the formula: \(a_c = \frac{{(44.44 \, \text{m/s})^2}}{700 \, \text{m}}\). Calculating the equation, we find that the centripetal acceleration experienced by the car is approximately 3.18 m/s².

In summary, when the 2000 kg car is traveling at a velocity of 160 km/h around a circular race course with a radius of 700 m, the centripetal acceleration it experiences is approximately 3.18 m/s². The centripetal acceleration is determined by the car's velocity and the radius of the circular path.

By using the formula \(a_c = \frac{{v^2}}{r}\), where \(a_c\) is the centripetal acceleration, \(v\) is the velocity, and \(r\) is the radius, we can calculate the value. The car's velocity is converted from km/h to m/s, and then the values are substituted into the formula to find the centripetal acceleration.

The force that it will take if applied perpendicular at 30° = 58 N

According to the formula of torque = τ and force = F,

τ =  r x F x sinθ --- equation 1

Given, F = 100 N , r = 0.2 m (r = radius)

We have to find the force when θ (angle) = 30°

Putting value in equation 1,

τ = 0.2 x 100 x sin (30°)

τ = 10 Nm

Value of torque from here = 10 Nm

Now to calculate the force perpendicular at 30° the equation will change as,

τ = r x F x cosθ --- equation 2

10 = 0.2 x F x cos 30°

(b) a Liberal? (c) a Conservative? (d) What fraction of voters participated in the local election?

Answer:

A) 0.331 ; B) 0.383 ; C) 0.286 ; D) 0.4862

Step-by-step explanation:

Given the following :

P(Independent(I)) = 46/100 = 0.46

P(Liberal(L)) = 30/ 100 = 0.3

P(Conservative(C)) = 24 / 100 = 0.24

Election participation (EP) :

P(EP | I) = 35 / 100 = 0.35

P(EP | L) = 62/100 = 0.62

P(EP | C) = 58/100 = 0.58

P(EP) = P(EP | L)*P(L) + P(EP | I)*P(I) + P(EP | C)*P(C)

P(EP) = (0.62*0.3) + (0.35*0.46) + (0.58*0.24)

P(EP) = 0.186 + 0.161 + 0.1392 = 0.4862

A) probability of Independent given that the person participated in election:

P(I Given EP) = [P(EP | I) * P(I)] / P(EP)

B) probability of Liberals given that the person participated in election:

P(L Given EP) = [P(EP | L) * P(L)] / P(EP)

= (0.62 * 0.3) / 0.4862

= 0.186 / 0.4862

= 0.383

C.) P(C Given EP) = [P(EP | C) * P(C)] / P(EP)

The equation of the line through the points (0, 9) and (3, 0) is y = -3x + 9.

To find the equation of a line passing through two given points, we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1), where (x1, y1) is one of the points on the line and m is the slope of the line.

First, we calculate the slope (m) using the formula: m = (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two given points. Substituting the values (0, 9) and (3, 0), we get m = (0 - 9)/(3 - 0) = -9/3 = -3.

Next, we choose one of the points, let's say (0, 9), and substitute its coordinates into the point-slope form: y - 9 = -3(x - 0).

Simplifying the equation, we get y - 9 = -3x, or rearranging it, y = -3x + 9.

Therefore, the equation of the line passing through the points (0, 9) and (3, 0) is y = -3x + 9.

Domain → (-∞, -1)∪(-1, ∞)

Range → (-∞, ∞)

Step-by-step explanation:

Given function is,

\(\frac{f(x)}{g(x)}=\frac{x^2+2x-5}{2x+2}\)

This function is not defined when the denominator is zero.

2x + 2 = 0

2x = -2

x = -1

Therefore, x = -1 is not in the domain of this function.

And the domain will be,

(-∞, -1)∪(-1, ∞)

For all values of x (except x = -1) we get some output values (value of \(\frac{f(x)}{g(x)}\)).

Therefore, range of the function will be (-∞, ∞).

The probability that the number drawn is a multiple of 2 or 3 is 8/15 or 0.53.

This can be easily found by finding the number of multiples of 2 and 3 between 1 and 15 and adding them together. The multiples of three go from 3 to 15 and therefore there are 5 such numbers. The multiples of two go from 2 to 14 and hence there are 7 such numbers. Therefore, when we add these two numbers together, we get 12.

This is the total number of multiples of 2 or 3 between 1 and 15. We divide this by the total number of elements in the box, which is 15, to get the probability that the number drawn is a multiple of 2 or 3. This comes out to be 8/15 or 0.53.
