Problem 3 current technology uses lasers for the inspection of solder-joint defects on printed circuit boards (pcbs). a particular manufacturer of laser-based inspection equipment claims that its product can inspect on average at least 10 solder joints per second when the joints are spaced 0.1 inch apart. the equipment was tested by a potential buyer on 30 different pcbs. in each case, the equipment was operated for exactly one second. the number of solder joints inspected on each run is found in the homework 2.xlsx file. the potential buyer wants to know whether the sample data refute the manufacturer’s claim. formulate appropriate hypotheses and answer with 95% confidence

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

i'm sorry i don't know

step-by-step explanation:

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
