Answer:
Step-by-step explanation:
Given that Human visual inspection of solder joints on printed circuit boards can be very subjective. Part of the problem stems from the numerous types of solder defects (e.g., pad non-wetting, knee visibility, voids) and even the degree to which a joint possesses one or more of these defects.
Let A- event inspect A found defective , B - inspector B found defective

,
a) Probability that the selected joint was judged to be defective by neither of the two inspectors=
b) Probability that the selected joint was judged to be defective by inspector B but not by inspector A
=

Hence
P(AB')\\=P(A)-P(AB)
= 0.0766-0.0624
=0.0142
3. Yes, the shapes are congruent, because all the corresponding sides are the same lengths.
The figure that isn't labeled with any letters was reflected across the X-axis at X =1
4)
JKL was rotated 180 degrees, then shifted 2 units to the left.
Answer:
no solution
Step-by-step explanation:
use grouping method:
f(x) = x^2 - 4x + 2
factor it:
when we try to factor the above equation, we see that there is no ordered pair in which the numbers multiple to -4 and add to 2, so there is no solution
A: How many text messages would you have to send or receive in order for the plans to cost the same each month?
Answer: 100
Step-by-step:
$.20x100=$20
$40+$20=$60
b: If you send or receive an average of 50 texts each month, which plan would you choose?Why?
Answer: A
Because $.20x50=$10
$40+$10=$50
