Answer:

see explanation

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides

(11)

given 2 sides 2, 6 , then

6 - 2 < x < 6 + 2

4 < x < 8

(12)

Given 2 sides 4, 12 , then

12 - 4 < x < 12 + 4

8 < x < 16

(13)

Given 2 sides 2, 11 , then

11 - 2 < x < 11 + 2

9 < x < 13

2x > -6 and x – 4 ≤ 3

Levart [38]

2x > -6

Divide both sides by 2.

x > -3

x - 4 ≤ 3

Add 4 to both sides.

x ≤ 7

Suppose an airport metal detector catches a person with metal 99% of the time. That is, it misses detecting a person with metal

frozen [14]

Answer:

The probability of missing the first metal-carrying person is P(x≤50)=0.395

Step-by-step explanation:

We define as success to: missing metal carrying detection.

p=0.01

P(x)= $\frac{n!}{x!(n-x)!} p^x(1-p)^{n-x}$

We look for the probability when all metal carring people is detected so x=0

P(x≤50)=1-P(x=0)= $1 - 0.99^{50}$ =0.395

Answer: ∠1 = 37.5°; ∠2 = 37.5°; ∠3 = 133°.

Step-by-step explanation:

∠1 = ∠2 = (180° - 105°) ÷ 2 = 37.5°

∠3 = 180° - 23° - 24° = 133°
