Answer:

1. U. 190

2.U. 155

3. U. 240

Step-by-step explanation:

Explanation: To find an angle of a triangle we add the angles we know about

EXAMPLE: 50 + 120. We need to find the third angle.

We know that Angles of triangles should add up to 360

So to find the third angle we add the angle we know about.

EXAMPLE: 50 + 120 = 170 then we Subtract the sum of a triangle *360*

EXAMPLE: 50 + 120 = 170

EXAMPLE: 170 - 360

EXAMPLE: = 190

That's how we find a third angle!

If this doesn't clarify how do to it enough just let me know and i can try to explain more in detail!

Hope this helps you!!!

Have a nice day!

Answer:

Percentage = 14.2%

Step-by-step explanation:

<u>Given the following data;</u>

Cost of plane ticket = £588

Airport tax = $130

£1 = $1.34

To find the percentage of the total cost spent on airport tax;

First of all, we would convert the ticket cost in pounds (£) to dollars ($).

Cost of plane ticket = £588 to $ = 588 * 1.34 = $787. 92

Total cost = Cost of plane ticket + Airport tax

Total cost = 787. 92 + 130

Total cost = $917.92

Percentage \; cost = \frac {130}{917.92} * 100

Percentage  = 0.1416 * 100

<em>Percentage cost = 14.16 to 1 d.p = 14.2%</em>

<em>Therefore, the percentage of the total cost spent on airport tax by Rimo is 14.2 percent. </em>

Using a confidence interval of proportions, it is found that the correct statement is given by:

D a confidence interval for estimating the cricket's true probability of landing on its feet is more narrow after the final 10 jumps than it was before the final 10 jumps.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which:

  • \pi is the sample proportion.
  • z is the critical value.
  • n is the sample size.

The margin of error is given by:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

The margin of error is inversely proportional to the square root of the sample size, hence, the higher the sample size, the narrower the interval is, hence option D is correct.
