(a) The top of the ladder is sliding down the wall at a rate of 3/2 m/sec.

(b) The angle between the ladder and the ground is changing at a rate of 1/2 rad/sec.

To solve this problem, we can use related rates, considering the ladder as a right triangle formed by the ladder itself, the wall, and the ground.

Let's denote:

x: the distance from the base of the ladder to the house (in meters)

y: the height of the ladder on the wall (in meters)

θ: the angle between the ladder and the ground (in radians)

Given:

dx/dt = -2 m/sec (the rate at which the base of the ladder is moving away from the house)

Using the Pythagorean theorem, we have:

x^2 + y^2 = 5^2 (since the ladder has a length of 5 meters)

Taking the derivative of both sides with respect to time (t), we get:

2x(dx/dt) + 2y(dy/dt) = 0

(a) To find dy/dt:

We can solve the equation above for dy/dt:

2x(dx/dt) + 2y(dy/dt) = 0

2(3)(-2) + 2y(dy/dt) = 0 (substituting x = 3 and dx/dt = -2)

-12 + 2y(dy/dt) = 0

2y(dy/dt) = 12

dy/dt = 12/(2y)

dy/dt = 6/y

Now, we need to find y. Using the Pythagorean theorem again:

x^2 + y^2 = 5^2

3^2 + y^2 = 5^2

9 + y^2 = 25

y^2 = 25 - 9

y^2 = 16

y = 4 (taking the positive value as y represents a length)

Substituting y = 4 into dy/dt = 6/y:

dy/dt = 6/4

dy/dt = 3/2 m/sec

Therefore, the top of the ladder is sliding down the wall at a rate of 3/2 m/sec.

(b) To find dθ/dt:

We can use trigonometry to relate θ, x, and y:

tan(θ) = y/x

Differentiating both sides with respect to time (t), we get:

sec^2(θ)dθ/dt = (x(dy/dt) - y(dx/dt))/x^2

Substituting the given values:

sec^2(θ)dθ/dt = (3(3/2) - 4(-2))/3^2

sec^2(θ)dθ/dt = (9/2 + 8)/9

sec^2(θ)dθ/dt = (25/2)/9

sec^2(θ)dθ/dt = 25/18

Since sec^2(θ) is equal to 1 + tan^2(θ) and tan(θ) = y/x:

sec^2(θ) = 1 + (y/x)^2

sec^2(θ) = 1 + (4/3)^2

sec^2(θ) = 1 + 16/9

sec^2(θ) = (9 + 16)/9

sec^2(θ) = 25/9

Substituting sec^2(θ) = 25/9 into the equation:

(25/9)dθ/dt = 25/18

Simplifying and solving for dθ/dt:

dθ/dt = (25/18) * (9/25)

dθ/dt = 1/2 rad/sec

Therefore, (b) the angle between the ladder and the ground is changing at a rate of 1/2 rad/sec.

We prove with the help of Strong Induction.

Let P(n) be the statement that Pn+1/Pn E N.

In order to prove this statement, we will utilize strong induction.So we are given that p + 1/p E N. We will show that P(n) is true for all n >= 1.

Let's consider the base case

P(1):P2/P1 = (p + 1/p)^2 - 2 = (p^2 + 2 + 1/p^2) - 2p/p = (p^2 + 1/p^2) - (2p - 2/p)

Since p + 1/p E N, both p and 1/p must be integers.

Hence, p^2 and 1/p^2 are also integers. This implies that (p^2 + 1/p^2) is an integer.

It only remains to show that (2p - 2/p) is an integer. This is equivalent to showing that 2p^2 - 2 E 0 mod p. But this is clearly true, since 2p^2 - 2 = 2(p^2 - 1) and p^2 - 1 is divisible by p.

Let's assume that P(k) is true for all k such that 1 <= k <= n. We need to prove that P(n+1) is true as well.

Now we need to prove that P(n+1) is true. In other words, we need to show that P(n+2)/P(n+1) E N, assuming that P(n+1)/P(n) E N and P(n)/P(n-1) E N.

Using the definition of P(n), we have:P(n+1)/P(n) E N and P(n)/P(n-1) E N imply that P(n+1) = aP(n) and P(n) = bP(n-1) for some integers a and b. Then:P(n+2)/P(n+1) = (P(n+2)/P(n+1)) * (P(n)/P(n)) = (P(n+2)P(n))/(P(n+1)P(n)) = (aP(n+1)P(n))/(bP(n)P(n+1)) = a/bIf we can show that a/b E N, then P(n+2)/P(n+1) E N, and P(n+1) satisfies the inductive hypothesis.

But this follows from the fact that a and b are integers and the product of two integers is always an integer.

Hence, P(n+1) is true for all n >= 1, by strong induction.Therefore, by strong induction, we have proved that if p + 1/p E N, then Pn+1/Pn EN for all nEN.

The correct option to the sentence "The percentage of people who have an IQ between 70 and 130 ?" is:

b. 95%.

To solve for the percentage of people who have an IQ between 70 and 130, we will have to use the standard deviation and the mean IQ.

It is given that: Mean = 100, Standard deviation = 15

Now we will use these values to find the percentage of people who have an IQ between 70 and 130.

The first step to this process is to standardize the IQ scores by converting them to Z-scores.

The formula for Z-score is:

Z = (X - µ) / σ, where X represents the IQ score, µ represents the mean IQ, and σ represents the standard deviation.

IQ score of 70:

Z = (70 - 100) / 15

Z = -2

IQ score of 130:

Z = (130 - 100) / 15

Z = 2

Now that we have the Z-scores for IQ scores of 70 and 130, we can find the percentage of people who have an IQ between these two scores. We will use the Z-table to do this. The Z-table provides the area under the standard normal distribution curve for a given Z-score.

From the Z-table, we can find that the area under the curve between Z = -2 and Z = 2 is approximately 0.9545. This means that approximately 95.45% of people have an IQ between 70 and 130.

Therefore, the correct option is: b. 95%.

P(z > 0.82) = 0.2061

P(z < -1.77) = 0.0384

P(-0.20 < z < 1.56) = 0.5199

P(1.12 < z < 1.43) =0.0550

P(z > -1.43) = 0.9236

To locate the chances of the usage of the same old ordinary distribution, we will use a well-known normal desk or a calculator. Here are the calculations for the given possibilities:

P(0 < z < 1.96):

Using the standard everyday desk, the place to the left of one.Ninety-six is 0.9750, and the vicinity to the left of zero is 0.5000. Therefore, the chance between zero and 1.96 is:

P(0 < z < 1.96) = 0.9750 - 0.5000 = 0.4750

P(-1.23 < z < 0):

Using the usual ordinary table, the vicinity to the left of -1.23 is 0.1093, and the area to the left of zero is zero.5000. Therefore, the possibility between -1.23 and 0 is:

P(-1.23 < z < 0) = 0.5000 - 0.1093 = 0.3907

P(z > 0.82):

Using the standard everyday table, the region to the left of zero.82 is zero.7939. Therefore, the possibility of z being extra than 0.82 is:

P(z > 0.82) = 1 - 0.7939 = 0.2061

P(z < -1.77):

Using the same old regular desk, the vicinity to the left of -1.Seventy-seven is zero.0384. Therefore, the chance of z being much less than -1.77 is:

P(z < -1.77) = 0.0384

P(-zero.20 < z < 1.56):

Using the standard ordinary desk, the area to the left of -0.20 is 0.4207, and the area to the left of 1.56 is 0.9406. Therefore, the opportunity between -0.20 and 1. Fifty-six is:

P(-0.20 < z < 1.56) = 0.9406 - 0.4207 = 0.5199

P(1.12 < z < 1.43):

Using the standard regular desk, the place to the left of 1.12 is 0.8686, and the location to the left of one. Forty-three is zero.9236. Therefore, the opportunity between 1.12 and 1. Forty-three is:

P(1.12 < z < 1.43) = 0.9236 - 0.8686 = 0.0550

P(z > -1.43):

Using the same old normal desk, the location to the left of -1.43 is zero.0764. Therefore, the possibility of z being greater than -1. Forty-three is:

P(z > -1.43) = 1 - 0.0764 = 0.9236

Proof:If [a] and [b] are not equal, then there must be some element c in the intersection of the equivalence classes [a] and [b]. i.e, c belongs to [a] and c belongs to [b].Thus, [a] ∩ [b] is not empty.

Let x be an element in [a], then x~a, and a~c (since c belongs to [a]) and hence x~c. So, x belongs to [c] which implies that [a] is a subset of [c].Now, let y be an element in [b], then y~b, and b~c (since c belongs to [b]) and hence y~c. So, y belongs to [c] which implies that [b] is a subset of [c].Thus, both [a] and [b] are subsets of [c].

Therefore, if [a] and [b] are not equal, then [a] and [b] are both subsets of [c] and hence the intersection of [a] and [b] is not empty. Thus, [a] and [b] are not disjoint. Hence, the proof by contradiction.

The cost price of the article is Rs. 165.

The equation of the regression line is: y = 1.5 + 0.95x

To find the equation of the regression line, we can use the formulas:

b = [n(Σxy) - (Σx)(Σy)] / [n(Σx²) - (Σx)²]

a = [(Σy)(Σx²) - (Σx)(Σxy)] / [n(Σx²) - (Σx)²]

Given the following data:

n = 4

Σx = 20

Σy = 25

Σxy = 144

Σx² = 120

Let's calculate the values step by step:

b = [4(144) - (20)(25)] / [4(120) - (20)²]

a) The x-intercepts of p(x) are x = 3 and x = -4/3.  b) The y-intercept of p(x) is y = -12.

a) To find the x-intercepts, we set p(x) = 0 and solve for x:

x + 3x² - 4x - 12 = 0

Simplifying the equation, we get:

3x² - 3x - 12 = 0

Factoring, we have:

(x - 3)(3x + 4) = 0

Setting each factor equal to zero, we find the x-intercepts:

x = 3 and x = -4/3

b) The y-intercept is the value of p(0), so we substitute x = 0 into the equation:

p(0) = 0 + 3(0)² - 4(0) - 12 = -12

Therefore, the y-intercept is -12.
