Answer:
The probability that a person has HIV given that the test negative is 0.0033.
Step-by-step explanation:
Denote the events as follows:
<em>X</em> = a person in Uganda had HIV
<em>Y</em> = a person in Uganda was tested positive for HIV.
The information provided is:
The probability that a person has HIV given that he/she was tested negative is:
Compute the probability of a person not having HIV as follows:
Compute the value of as follows:
Thus, the probability that a person has HIV given that he/she was tested negative is 0.0033.
Answer:
Step-by-step explanation:
f(x)=2x+3
f(x)=0
2x+3=0
2x=-3
x=-3/2
x=-1.5
when x=0,y=f(x)=2(0)+3=3
so one point is (0,3)
when x=2,y=f(x)=2(2)+3=4+3=7
so point is (2,7)
Draw a line through (0,3) and (2,7)
see where it cuts x-axis.
it is the zero of the linear equation.
zero is x=-1.5
Answer:
a) 12cm
b) 360cm²
c) 2160cm cubed
Step-by-step explanation:
a)
you would use Pythagoras theorem for A
so half of 18 is 9
15² - 9² = 144
the square root of 144 is 12
the height is 12cm
b)
18 x 20 = 360cm²
c)
csa x L
csa = b x h divide by 2
18 x 12 = 216cm²/2 = 108cm²
108xm² x 20cm = 2160cm cubed
