Answer:
EF=BC (by CPCT) if both Triangle are ~
Answer:
(146 + 0i)
Step-by-step explanation:
(11+5i)(11-5i)
The formula is :
(a+bi) • (x+yi) = ax+by•i^2+(ay+bx)i
and since i^2 = -1 it can be written as :
ax - by + (ay + bx) i
( 11 + 5i) • ( 11 - 5i) =
(146 + 0i)

Answer:
Type I error: The correct option is (C).
Type II error: The correct option is (D).
Step-by-step explanation:
The type-I-error is the probability of rejecting the null hypothesis when the null hypothesis is true.
The type-II-error is the probability of filing to reject the null hypothesis when in fact it is false.
The hypothesis in this problem can be defined as follows:
Null hypothesis (H₀): The percentage of adults who have a job is equal to 88%.
Alternate Hypothesis (Hₐ): The percentage of adults who have a job is different from 88%.
The type-I-error in this case will be committed when we conclude that the percentage of adults who have a job is different from 88% when in fact it is equal to 88%.
The type-II-error in this case will be committed when we conclude that the percentage of adults who have a job is equal to 88% when in fact it is different than 88%.
