Answer:
see below
Step-by-step explanation:
First we need to draw segment UT
We are using similar triangle
Triangle BTU is similar to triangle EUT
UT ≅ TU reflexive property
BT ≅ EU given
BU ≅ ET given
△UBT ≅ △TEU by SSS congruence postulate
<B ≅ <E corresponding parts of congruent triangles are congruent
Answer:
The proportion of the population which is infected is =0.07692
Step-by-step explanation:
Let the events be,
A: a person is infected.
B: the test result is positve
According to the question we have,
So
Hence,
Now
The probability that a person is infected is
So the probability that a person is infected is =0.07692.
The proportion of the population which is infected is
Hence the proportion of the population which is infected is =0.07692

ANSWER: -60
EXPLANATION: To solve for (-10) - |(-20) – (+30) |, we need to do:
−10−| −20 − 30|, which equals −10−|−50|. Next, we do −10−50, which is -60.
−10−|−20−30|
= −10−|−50|
= −10−50
= −60
