If ln y = (ln x)2 + 2, then find dy / dx in terms of x and y.

Answers

Answer:  The required value of(dy)/(dx) is(y)/(1-y).

Step-by-step explanation:   We are given to find the value of(dy)/(dx) from the following equation :

\ln y=(\ln x)^2+2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Differentiating both sides of equation (i) with respect to x, we have

(d)/(dx)\ln y=(d)/(dx)((\ln x)^2+2)\n\n\n\Rightarrow (1)/(y)(dy)/(dx)=(d)/(dx)(\ln x)^2+(d)/(dx)2\n\n\n\Rightarrow (1)/(y)(dy)/(dx)=2\ln x*(d)/(dx)\ln x+0\n\n\n\Rightarrow (1)/(y)(dy)/(dx)=2(\ln x)/(x)\n\n\n\Rightarrow (dy)/(dx)=(2y\ln x)/(x).

Thus, the required value of(dy)/(dx) in terms of x and y is (2y\ln x)/(x)..

In a survey of a community, it was found that 85% of the people like winter season and 65% like summer season. If none of them did not like both seasonsi) what percent like both the seasons

Answers

Answer:

50%

Step-by-step explanation:

Let :

Winter = W

Summer = S

P(W) = 0.85

P(S) = 0.65

Recall:

P(W u S) = p(W) + p(S) - p(W n S)

Since, none of them did not like both seasons, P(W u S) = 1

Hence,

1 = 0.85 + 0.65 - p(both)

p(both) = 0.85 + 0.65 - 1

p(both) = 1.50 - 1

p(both) = 0.5

Hence percentage who like both = 0.5 * 100% = 50%

A polling company conducts an annual poll of adults about political opinions. The survey asked a random sample of 419 adults whether they think things in the country are going in the right direction or in the wrong direction, 54% said that things were going in the wrong direction. How many people would need to ve surveyed for a 90% confidence interval to ensure the margin or error would be less than 3%?

Answers

Answer: 747

Step-by-step explanation:

When prior estimate of population proportion (p) is given , then the formula to find the sample size is given by :-

n=p(1-p)((z^*)/(E))^2

, where z* = Critical value and E = Margin of error.

As per given , we have

p= 0.54

E= 0.03

Critical value for 90% confidence : z* = 1.645

Then, the required sample size is given by :-

n=0.54(1-0.54)((1.645)/(0.03))^2

n=0.2484(54.8333333333)^2

n=746.862899999\approx747

Hence, the number of people would be needed = 747
