An exit poll in an election is a survey taken of voters just after they have voted. One major use of exit polls has been so that

Answer:

P(A) = 0.39

Step-by-step explanation:

We are given;

P(W|A) = 0.7

P(W|A^c ) = 0.3

We are told that 60% of the respondents said they voted for A. Thus;

P(A|W) = 60% = 0.6

Now, using the principle of drawing lots, we can be able to find the probability of the event that they are willing to participate in the exit poll which is P(W).

Thus;

P(W) = [P(W|A) × P(A)] +[P(W∣A^c) × P(A^c)]

Now, P(A^c) can be expressed as 1 - P(A)

Thus, we now have;

P(W) = [P(W|A) × P(A)] + [P(W∣A^c) × (1 - P(A)]

Plugging in the relevant values gives;

P(W) = 0.7P(A) + 0.3(1 - P(A))

P(W) = 0.7P(A) + 0.3 - 0.3P(A)

P(W) = 0.3 + 0.4P(A)

Now,using Baye's theorem, we can find an expression for P(A|W)

Thus;

P(A|W) = [P(A ∩ W)]/P(W)

This can be further expressed as;

P(A|W) = [P(A) × P(W|A)]/P(W)

Plugging in relevant values, we have;

0.6 = 0.7P(A)/(0.3 + 0.4P(A))

Cross multiply to get;

0.6(0.3 + 0.4P(A)) = 0.7P(A)

0.18 + 0.24P(A) = 0.7P(A)

0.18 = 0.7P(A) - 0.24P(A)

0.46P(A) = 0.18

P(A) = 0.18/0.46

P(A) = 0.39

Find size of angle x pls..

mina [271]

Answer:

x = 115

Step-by-step explanation:

Sum of angles around a point = 360

i.e,

=> 164 + 81 + x = 360

=> 245 + x = 360

=> x = 360 - 245

=> x = 115

If sin²∅ + sin∅ = 1 , then what is the value of sin²∅ + sin⁴∅.

Yakvenalex [24]

Answer:

Step-by-step explanation:

Given sin²∅ + sin∅ = 1, we are to find the value of sin²∅ + sin⁴∅. ... 2

From sin²∅ + sin∅. = 1; sin²∅ = 1 - sin∅. ... 3

Substitute equation 3 into 1

sin²∅ + sin⁴∅

= sin²∅ + (sin²∅)²

= (1 - sin∅)+( 1 - sin∅)²

open the parenthesis

= 1 - sin∅+ (1-2sin∅+ sin²∅)

= 1 - sin∅+ 1-2sin∅+ sin²∅

= 1+1-sin∅-2sin∅+sin²∅

= 2 - 3sin∅+sin²∅

Since sin²∅ = 1 - sin∅, the resulting equation becomes;

= 2 - 3sin∅+(1 - sin∅)

= 2 - 3sin∅+1-sin∅

= 3-4sin∅

If increasing 50 by x% is equal to the result of decreasing 70 by x%. what is the value of x?

ozzi

Increasing 50 by x% can be written as:

$50 + \frac{x}{100} =50+0.01x$ .................(1)

Decreasing 70 by x % can be represented by the expression:

$70 + \frac{x}{100} =70-0.01x$ ...........(2)

Now we are given in the question that if we increase 50 by x% and 70 by x%, then the two values are equal.

so equating (1) and (2) , we get

$50 +0.01 x =70 - 0.01x$

bringing 0.01x to the left side:

$50 +0.01x +0.01x = 70$

$50 +0.02x = 70$

taking 50 to the right side, subtracting it from 70

$0.02x = 70-50$

$0.02x = 20$

dividing both sides by 0.02

$\frac{0.02x}{0.02} =\frac{20}{0.02}$
