<h3><u>Given</u><u>:</u><u>-</u></h3>

  • The hypotenuse of a right angle triangle is 13cm.

  • One other side of the triangle is 1cm shorter than the hypotenuse.

<h3><u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u><u>-</u></h3>

Find the third scale of the triangle .

<h3><u>Solution:-</u><u> </u></h3>

Let the third Side be x.

According to the question,

★ Hypotenuse = 13 cm

★ Other side = Hypotenuse - 1 [ Given ]

= 13 cm - 1 cm

= 12 cm

Now,

<u>By pythagoras theorem</u>,

13² = 12² + x²

⇒ 169 = 144 + x²

⇒ x² = 169 - 144

⇒ x² = 25

⇒ x = √25

⇒ x = 5 cm

Hence, the third scale of the triangle is 5 cm.

Solve x2 – 8x = 20 by completing the square. Which is the solution set of the equation?
Scorpion4ik [409]

Answer:

<h2>x=2 , x = 6</h2>

Step-by-step explanation:

x² – 8x = 20 ⇌ x² – 2(4)x  = 4 + 16 ⇌ x² – 2(4)x - 16 = 4 ⇌ (x - 4)² = 4

⇌ x - 4 = 2 or x - 4 = -2 ⇌ x = 6 or x = 2

Answer:

The area of the triangle is 10 square units.

Step-by-step explanation:

The formula for area of a triangle is A = \frac{1}{2}bh.  

The problem gives us this information:

b = 4 units

h = 5 units

You can use the formula and plug the numbers into the equation to find your answer of 10 square units.

The data given to the right includes data from ​candies, and of them are red. The company that makes the candy claims that ​% of
Dafna1 [17]

Using the z-distribution, the 95% confidence interval for the percentage of red candies is of (7.84%, 33.18%). Since 33% is part of the interval, there is not enough evidence to conclude that the claim is wrong.

<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.

In this problem, we have a 95% confidence level, hence\alpha = 0.95, z is the value of Z that has a p-value of \frac{1+0.95}{2} = 0.975, so the critical value is z = 1.96.

Researching this problem on the internet, 8 out of 39 candies are red, hence the sample size and the estimate are given by:

n = 39, \pi = \frac{8}{39} = 0.2051

Hence the bounds of the interval are:

  • \pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2051 - 1.96\sqrt{\frac{0.2051(0.7949)}{39}} = 0.0784
  • \pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2051 + 1.96\sqrt{\frac{0.2051(0.7949)}{39}} = 0.3318

As a percentage, the 95% confidence interval for the percentage of red candies is of (7.84%, 33.18%). Since 33% is part of the interval, there is not enough evidence to conclude that the claim is wrong.
