Just before a referendum on a school budget, a local newspaper polls 402 voters to predict whether the budget will pass. Suppos

Sliva [168]

Answer:

21.21%

Step-by-step explanation:

Assume that proportion of support follows normal distribution.For resulting in defeat the proportion of support should less than 0.5.Given that the proportion of support is p= 0.52.

Sample size(n)= 402

We know that standard deviation is given as

$\sigma = \sqrt {\dfrac {p(1-p)}{n}}$

Now by putting the values

$\sigma = \sqrt {\dfrac{0.52\times 0.48}{402}}$

σ=0.0249

Proportion of support follows normal distribution with mean is 0.52 and standard deviation is 0.0249

We know that $Z=\dfrac{\bar{X}-\mu }{\sigma }$

$Z=\dfrac{0.5-0.52 }{0.0249}$

Z= -0.80

So P(Z<-.80) =0.2118 from standard table.

So the probability of news paper to predict defeat is 21.21%

For this case we must find the quotient of the following expression:

$\frac {(- 8x ^ 2 * y) (- 7x ^ 5 * y ^ 3)} {- 2x ^ 2 * y ^ 3}$

We can rewrite the expression as:

(We take into account that $- * - = +$ )

$\frac {56x ^ 2 * y * x ^ 5 * y ^ 3} {- 2x ^ 2 * y ^ 3} =$

By definition of multiplication of powers of the same base, we place the same base and add the exponents:

$\frac {56x ^ {2 + 5} * y ^ {1 + 3}} {- 2x ^ 2 * y ^ 3} =\\\frac {56x ^ {7} * y ^ {4}} {- 2x ^ 2 * y ^ 3} =$

By definition of division of powers of the same base, we place the same base and subtract the exponents:

$-28x^{ 7-2} * y^{ 4-3} =\\-28x ^ 5 * y$

Answer:

$-28x ^ 5 * y$
