Suppose 40% of the students in a university are baseball players. If a sample of 781 students is selected, what is the probabili

3241004551 [841]

Answer:

$P(p>0.43) = 0.0436$

Step-by-step explanation:

Given

$p = 40\%$ -- proportion of baseball players

$n = 781$ --- selected sample

Required

Determine P(p>43%)

First, calculate the z score using:

$Z = \frac{\^{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

This gives:

$Z = \frac{48\%-40\%}{\sqrt{\frac{40\% *(1 - 40\%)}{781}}}$

Convert % to decimal

$Z = \frac{0.43-0.40}{\sqrt{\frac{0.40 *(1 - 0.40)}{781}}}$

$Z = \frac{0.43-0.40}{\sqrt{\frac{0.40 *0.60}{781}}}$

$Z = \frac{0.43-0.40}{\sqrt{\frac{0.24}{781}}}$

$Z = \frac{0.03}{\sqrt{0.00030729833}}$

$Z = \frac{0.03}{0.01752992669}$

$Z = 1.71$

So:

$P(p>0.43) = P(Z>1.71)$

$P(p>0.43) = 1 - P(Z$

$P(p>0.43) = 1 - 0.9564$

$P(p>0.43) = 0.0436$

Area as a sum:<br> Area as a Product:<br><br><br> I need the are as a sum Nd a product

PSYCHO15rus [73]

Given:

The area model.

To find:

The area as a sum and area as a product.

Solution:

The four terms of the area model are $2x^2,10x, 3x, 15$ .

The area as a sum is the sum of all the terms of given area model.

Area as a sum = $2x^2+10x+3x+15$

= $2x^2+13x+15$

The area as a product is the factor form of sum of all the terms of given area model.

Area as a product = $2x^2+10x+3x+15$

= $2x(x+5)+3(x+5)$

= $(x+5)(2x+3)$

Therefore, the area as a sum is $2x^2+13x+15$ and the area as a product is $(x+5)(2x+3)$ .
