An example of basic trigonometric functions question is find tan \frac{11\pi }{4}.

<h3>What are trigonometric functions?</h3>

The term trigonometric function is known to be made up of functions such as sine (sin), cosine (cos), tangent (tan), etc., that stands for the ratios of sides of all right triangles.

To solve for tan \frac{11\pi }{4}

It will be  \frac{11\pi }{4} = 2\pi + \frac{3\pi }{4}

θ = \pi -\frac{3}{4} \pi

θ = \frac{\pi }{4}

To know the right angle,

 θ = \frac{\pi }{4} x 180/4 = 45⁰

tan θ = 1

Therefore,  tan \frac{11\pi }{4} = -1

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

ehidna [41]

Answer:

(A) There is convincing evidence that there is no difference in the mean delivery times.

(B) There is convincing evidence that there is a difference in the mean delivery times.

(C) There is convincing evidence that the mean delivery time from Japan to Texas is greater than the mean delivery time from Texas to Japan.

(D) There is not convincing evidence that the mean delivery time from Japan to Texas is greater than the mean delivery time from Texas to Japan.

(E) The t-test cannot be used for sample sizes that are this small.

Explanation:

The correct option is;

(A) There is convincing evidence that there is no difference in the mean delivery times.

Step-by-step explanation:

Here we have the formula for the two-sample t-test given s;

 

To Texas N₁ = 12,   =8.74 σ₁ = 2.92 SE Mean₁ = 0.84

To Japan N₂ = 9   = 6.75 σ₂ = 2.56 SE Mean₁ = 0.85

t =   1.667

Where the null hypothesis is

mu To Texas = mu To Japan and the alternative is

mu To Texas > mu To Japan

Here since the observed P value of P = 0.058 is greater than the significance level of 0.05 we fail to reject the null hypothesis and we will therefore, not accept the alternative hypothesis.

Hence, there is convincing evidence that there is no difference in the mean delivery times.
