Answer:

The shape of the graph of the parametric equations given is:

  • <u>B. ellipse</u>.

Step-by-step explanation:

By inserting each of the equations given in a graphing calculator (Annex 1), it can be identified that both the first and second equations have an elliptical or ellipse shape, which is characterized by being periodic in the two directions in which it runs. Thus, the equation x = 3 cos t runs with elliptical motion on the Y-axis of the Cartesian plane, while the equation y = 2 without t + 1 runs with elliptical motion on the X-axis.

vampirchik [111]

You are given a fraction in simplest form. The possible denominators are 3, 6, 7, 9

<u>Solution:</u>

Given that, You are given a fraction in simplest form.

The numerator is not zero. When you write the fraction as a decimal, it is a repeating decimal.

We have to find which numbers from 1 to 10 could be the denominator

Now, let us check each number by considering the numerator as 1

Then,  

1 \rightarrow \frac{1}{1}=1 ⇒ non repeating

2 \rightarrow \frac{1}{2}=0.5 ⇒ non repeating

3 \rightarrow \frac{1}{3}=0.333333333333 ⇒ repeating

4 \rightarrow \frac{1}{4}=0.25 ⇒ non repeating

5 \rightarrow \frac{1}{5}=0.2 ⇒ non repeating

6 \rightarrow \frac{1}{6}=0.1666666666666 ⇒ repeating

7 \rightarrow \frac{1}{7}=0.1428571428571 ⇒ repeating

8 \rightarrow \frac{1}{8}=0.125 ⇒ non repeating

9 \rightarrow \frac{1}{9}=0.11111111111111 ⇒ repeating

10 \rightarrow \frac{1}{10}=0.1 ⇒ non repeating

If we want to test with any other numerator. Suppose 5, then numerator is 5 x 1, which means 5 divided by denominator equals with 5 x 1 divided by denominator. So its again product of the numerator we want and above values, then, non repeating stays non repeating and repeating stays repeating.

Hence, the possible denominators are 3, 6, 7, 9

Zepler [3.9K]

The size of the sample they should take to estimate p with a 2% margin of error and 90% confidence is n = 1691.

In statistics, the margin of error is just the degree of a significant error in the outcomes of random sample surveys.

The formula of margin error is, E = z√((p-vector)(1 - (p-vector)) ÷ n)

E = 2% = 0.02

Confidence level = 90%

Now, the proportion is not given so adopt nominal (p-vector) = 0.05

The critical value at CL of 90% is 1.645.

Thus, making n the subject,

n = z²(((p-vector) × (1 - (p-vector))) ÷ E²)

n = 1.645²((0.5 × 0.5) ÷ 0.02²)

n = 1691.266

n ≈ 1691
