3(a-b) and 3a-3b. Equivalent
2a(2+b) and 4ab. Not equivalent
Answer:
see explaination
Step-by-step explanation:
Here the null hypothesis is that the PCB survives against the alternate that the PCB 'does not survive'. The test says that the PCB will survice if it is classified as 'good'; or, it will not survive if it is classifies as 'bad'.
a. The Type II error is the error committed when a PCB which cannot actually survive is classified as 'good'.
b. Therefore P(Type II error) = P(The PCB is classified as 'good' | PCB does not survives) = 0.03.
The bottom line in the red triangle is 3 units long.
The top line of the blue triangle is 6 units long.
Divide the larger by the smaller to get the scale factor: 6 / 3 =2
The scale factor is 2
Step by step, we have:
1 • （-1）= -1
Then -1 • 1 = -1 and -1 • （-1）= 1 =》 1 - 1 = 0
The answers is 0
