The vertex angle of an isosceles triangle measures 26° . The base is 30 units long. What is the length of a leg of the isosceles
sergejj [24]

Answer:

65.46 units

Step-by-step explanation:

Given the information:

  • The vertex angle of an isosceles triangle measures 26°

=> the leg angle is:

= (180°  - 26° )/2

= 77°

  • The base is 30 units

Let x is the length of the leg side (x>0)

We use cosine law to find x, we have:

30^{2} = x^{2} +x^{2} -2xxCos(26) Because the  isosceles has two equal leg sides

<=> 30^{2} = 2x^{2} - 1.79x^{2}

<=> 0.21x^{2}  = 30^{2}

<=> x^{2} =4285

<=> x = 65.46 units

Hope it will find you well.

A certain firm has plants A, B, and C producing respectively 35%, 15%, and 50% of the total output. The probabilities of a non-d
Sliva [168]

Answer:

There is a 44.12% probability that the defective product came from C.

Step-by-step explanation:

This can be formulated as the following problem:

What is the probability of B happening, knowing that A has happened.

It can be calculated by the following formula

P = \frac{P(B).P(A/B)}{P(A)}

Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.

-In your problem, we have:

P(A) is the probability of the customer receiving a defective product. For this probability, we have:

P(A) = P_{1} + P_{2} + P_{3}

In which P_{1} is the probability that the defective product was chosen from plant A(we have to consider the probability of plant A being chosen). So:

P_{1} = 0.35*0.25 = 0.0875

P_{2} is the probability that the defective product was chosen from plant B(we have to consider the probability of plant B being chosen). So:

P_{2} = 0.15*0.05 = 0.0075

P_{3} is the probability that the defective product was chosen from plant B(we have to consider the probability of plant B being chosen). So:

P_{3} = 0.50*0.15 = 0.075

So

P(A) = 0.0875 + 0.0075 + 0.075 = 0.17

P(B) is the probability the product chosen being C, that is 50% = 0.5.

P(A/B) is the probability of the product being defective, knowing that the plant chosen was C. So P(A/B) = 0.15.

So, the probability that the defective piece came from C is:

P = \frac{0.5*0.15}{0.17} = 0.4412

There is a 44.12% probability that the defective product came from C.

How to solve systems of equation
Afina-wow [57]
Well its easy mean search a video in YouTube
there are two types for systems of question:
The method for elimination
The method for substitution

The elimination only that u have to do is found x or y hat are the sam,e number with different symbols ↓↓like this↓↓

- 7y + 3x = 45
  7y + 12x = 33

the y is cancel and... u know the process..
But the method for substitution is different u only need to put the y en the problem and that's it, and when u found the valor of x u can solve for y ↓↓like this↓↓  

4x - 2y = 24
y = x - 5

4 (x - 5) = 24
4x - 20 = 24
     +20  +20
4x = 44
4x/4 = 44/4
x = 11
