The <u>comparison</u> and <u>contrast</u> between a square and an <em>equilateral triangle</em> are stated and explained below:

What is a <u>square</u>? A <u>square</u> is a <em>plane shape</em> with an equal length of sides. This implies that the <em>measure</em> of its length is the same as that of its <u>breadth</u>.

What is an equilateral triangle? A <em>triangle</em> is a <em>plane shape</em> with<u> three </u>sides, and a <em>sum </em>of its <u>internal</u> angles to equal 180^{o}. Thus an <em>equilateral triangle </em>is a type of triangle with <em>equal lengths of sides</em>, and therefore equal internal angles.

<u>Comparison</u>: i. The two shapes have <em>equal lengths</em> of sides.

ii. An equilateral triangle and a square are examples of <u>plane shapes</u>.

<u>Contrast</u>: i. An equilateral triangle has<em> three sides</em>, while a square has <em>four sides</em>.

ii. An equilateral triangle has <em>three internal angles</em>, while a square has <em>four internal angles</em> which are right angles.

iii. The sum of <u>internal </u>angles of an equilateral triangle is 180^{o}, while that of a square is 360^{o}.

Consider a series system composed of 4 separate components where each component has a 30% chance of failing. Assume each compone
Marina86 [1]

Answer:

16.15% probability that exactly 3 of them would function

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

Probability of each system working:

4 components, which means that n = 4

Each has a 30% probability of failing, so p = 1 - 0.3 = 0.7

For the system to work, all 4 components have to work. This is P(X = 4).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 4) = C_{4,4}.(0.7)^{4}.(0.3)^{0} = 0.2401

0.2401 probability of a system working.

If you have 7 of these systems, what is the probability that exactly 3 of them would function?

Now 7 systems, so n = 7

0.2401 probability of a system working.

We have to find P(X = 3).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 3) = C_{7,3}.(0.2401)^{3}.(0.7599)^{4} = 0.1615

16.15% probability that exactly 3 of them would function

Can someone help me solve this?
Sergio [31]

Answer:

m<c = 104°

m<d = 80°

Step-by-step explanation:

Recall: Opposite angles of a cyclic quadrilateral are supplementary. Therefore, their sum equals 180°. Thus:

m<c + 76° = 180°

m<c + 76° - 76° = 180° - 76° (subtraction property of equality)

m<c = 104°

m<d + 100° = 180°

m<d +100° - 100° = 180° - 100° (subtraction property of equality)

m<d = 80°
