Answer:

Angle A = 30.8

Angle B = 33.2

Step-by-step explanation:

180 - 116 = 64

This means that the other two angles need to add up to 64.

I just plugged in numbers until it worked.

I got that x = 14.6

2x + 4

2(14.6) + 4

29.2 + 4

33.2

3x - 13

3(14.6) - 13

43.8 - 13

30.8

Those are your angles. To make sure they are correct you just need to add up all the angles and make sure that they equal to 180.

116 + 33.2 + 30.8 =

180

Which of the following is the solution to | X-13 |< 18 ?

Furkat [3]

Answer:

A. x<31 and x > -5

Step-by-step explanation:

| X-13 |< 18

Seperate into 2 equations, one positive and one negative, remembering to flip the inequality for the negative

x-13 < 18 and x -13 > -18

Add 13 to each side

x-13+13 < 18+13 and x-13+13> -18+13

x < 31 and x>-5

Based on FAA estimates the average age of the fleets of the 10 largest U.S. commercial passenger carriers is 13.4 years with a s

Aliun [14]

Answer : 0.0129

Step-by-step explanation:

Given : Based on FAA estimates the average age of the fleets of the 10 largest U.S. commercial passenger carriers is $\mu=13.4$ years and standard deviation is $\sigma=1.7$ years.

Sample size : $n=40$

Let X be the random variable that represents the age of fleets.

We assume that the ages of the fleets of the 10 largest U.S. commercial passenger carriers are normally distributed.

For z-score,

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For x=14

$z=\dfrac{14-13.4}{\dfrac{1.7}{\sqrt{40}}}\approx2.23$

By using the standard normal distribution table , the probability that the average age of these 40 airplanes is at least 14 years old will be :-

$P(x\geq 14)=P(z\geq2.23)\\\\=1-P(z$

Hence, the required probability = 0.0129

For a triangle with the length of its sides of 5/36, 1/3 and 13/36, determine if it is a right triangle?

Anuta_ua [19.1K]

Yes it is. Input the numbers into the pythagorean theorem,

${a}^{2} + {b}^{2} = {c}^{2}$

and if they equal each other it is a right triangle.
