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:

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

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

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

$P(p>0.43) = 0.0436$

nasir baked a pie, cut it in fourths he then took each of the piece and cut them in half. what fraction of the original pie does

Olin [163]

So 1/4ths
the he cut each pie into 1/2
remember that dividing by 2 is the same as multiplying by 1/2
1/2 times 1/4=1/8
each piece is 1/8 of the original pie

Which graph below BEST represents a quadratic equation whose solutions are x = –4 and x = 2? A B C D in the picture wich one is

krok68 [10]

Answer:

Graph (2)

Step-by-step explanation:

We have to find the graph that represents the solutions of the quadratic equation as x = -4 and x = 2

Graph which has x-intercepts as x = 2 and x = -4 will be the answer.

Graph (1)

x-intercepts in this graph are x = -2 and x = 4

Not the answer.

Graph (2)

x-intercepts in this graph are x = -4 and x = 2

This option will be the answer.

Graph (3)

Only one x-intercept has been given in this graph

Not the answer.

Graph (4)

x-intercepts are x = -5 and x = -3

Not the answer.
