Answer and Step-by-step explanation:
The computation is shown below:
Let us assume that
Spam Email be S
And, test spam positive be T
Given that
P(S) = 0.3


Now based on the above information, the probabilities are as follows
i. P(Spam Email) is
= P(S)
= 0.3

= 1 - 0.3
= 0.7
ii. 


= 0.8906
iii. 


= 0.0221
We simply applied the above formulas so that the each part could come
The value of x in the triangle is 61.9°.
Answer:
answer is (C)
Step-by-step explanation:
this is a right angle triangle
so tan 60 degree = bc/6
√3. = bc/6
√3×6= bc
10.39 inches
-8x+4=36
-4 -4
-8x=32
divde be -8 on both sides
x=-4
