if you were given the chance to write this speech with both aquino and locsin, what issues in 1986 would you like to address wit

Inessa05 [86]

The issues I would address in a speech with Corazon Aquino and Teddy Locsin are external debt, corruption, crisis, and communist

Maria Corazon Aquino was a President of the Philippines elected in 1986. This female politician is worldwide known for her speech in 1986 before the U.S. Congress.

In this speech, Corazon Aquino wanted to obtain $200-million aid for the Philippines because this country was going through an important social, economic and political crisis. This speech was written by Teddy Locsin but delivered by Aquino and it is considered one of the most moving speeches during history.

In this context, if I could write this speech again, I would include all important issues related to the Philippines in 1986. This includes that:

The Philippines had a big external debt
Previous corrupt governs had worsened the situation of this country
There were guerrillas and communist groups
The country needed resources to solve the crisis
Families were suffering due to the general crisis of the country

company manufactured six television sets on a given day, and these TV sets were inspected for being good or defective. The resul

lana [24]

Sampling distribution involves the proportions of a data element in a given sample.

<em>The proportion of Good TV set is 0.67</em>
<em>The number of ways of selecting 5 from 6 TV sets is 6</em>
<em>The number of ways of selecting 4 from 6 TV sets is 15</em>

<em />

Given

$n = 6$

Sample Space = Good, Good, Defective, Defective, Good, Good

<u>(a) Proportion that are good</u>

From the sample space, we have:

$Good = 4$

So, the proportion (p) that are good are:

$p = \frac{Good}{n}$

$p = \frac{4}{6}$

$p = 0.67$

<u>(b) Ways to select 5 samples (without replacement)</u>

This is calculated using:

$^nC_r = \frac{n!}{(n - r)!r!}$

Where

$r = 5$

So, we have:

$^6C_5 = \frac{6!}{(6 - 5)!5!}$

$^6C_5 = \frac{6!}{1!5!}$

$^6C_5 = \frac{6 \times 5!}{1 \times 5!}$

$^6C_5 = \frac{6}{1}$

$^6C_5 = 6$

Hence, there are 6 ways

<u>(c) All possible sample space of 4</u>

First, we calculate the number of ways to select 4.

This is calculated using:

$^nC_r = \frac{n!}{(n - r)!r!}$

Where

$r = 4$

So, we have:

$^6C_4 = \frac{6!}{(6 - 4)!4!}$

$^6C_4 = \frac{6!}{2!4!}$

$^6C_4 = \frac{6 \times 5 \times 4}{2 \times 1 \times 4!}$

$^6C_4 = \frac{30}{2}$

$^6C_4 = 15$

So, the table is as follows:

$\left[\begin{array}{ccc}TV&Good&Proportion\\1,2,3,4&2&0.5&2,3,4,5&2&0.5&3,4,5,6&2&0.5\\4,5,6,1&3&0.75&5,6,1,2&4&1&6,1,2,3&3&0.75\\1,2,3,5&3&0.75&3,5,6,2&3&0.75&1,3,4,5&2&0.5\\1,3,4,6&2&0.5&1,4,5,2&3&0.75&2,4,6,1&3&0.75\\2,4,6,3&2&0.5&2,4,6,5&3&0.75&3,5,6,1&3&0.75\end{array}\right]$

The proportion column is calculated by dividing the number of Good TVs by the total selected (4) i.e.

$p = \frac{Good}{n}$

<u>(d) The sampling distribution</u>

In (a), we have:

$p = 0.67$ --- proportion of Good TV

The sampling error is calculated as follows:

$SE_n = |p - p_n|$

So, we have:

$\left[\begin{array}{ccc}TV&Good&SE\\1,2,3,4&2&0.17&2,3,4,5&2&0.17&3,4,5,6&2&0.17\\4,5,6,1&3&0.08&5,6,1,2&4&0.33&6,1,2,3&3&0.08\\1,2,3,5&3&0.08&3,5,6,2&3&0.08&1,3,4,5&2&0.17\\1,3,4,6&2&0.17&1,4,5,2&3&0.08&2,4,6,1&3&0.08\\2,4,6,3&2&0.17&2,4,6,5&3&0.08&3,5,6,1&3&0.08\end{array}\right]$

A shot putter releases the shot some distance above the level ground with a velocity of 12. 0 m/s, 51. 0∘ above the horizontal.

KIM [24]

A) The x-component of the shot's acceleration while in flight is; aₓ = 0 m/s²

B) The y-component of the shot's acceleration while in flight is;

a_y = -9.8 m/s²

C) The x-component of the shot's velocity while in flight is; vₓ = 7.55 m/s

D) The y-component of the shot's velocity while in flight is;

a_y = 9.32 m/s

<h3>Projectile motion</h3>

A) The x-component of the shot's acceleration while in flight?

aₓ = 0 m/s²

B) Since the object is thrown vertically, it means that it is against gravity and as such acceleration due to gravity will be negative,

Thus, the y-component of the shot's acceleration while in flight is;

a_y = -9.8 m/s²

C) The x-component of the shot's velocity at the beginning of its trajectory is; v_x = v cos θ

v_x = 12 cos 51

v_x = 7.55 m/s

D) The y-component of the shot's velocity at the beginning of its trajectory is; v_y = v sin θ

v_y = 12 sin 51

v_y = 9.32 m/s
