Atest for the presence of a certain disease has probability 0.20 of giving a false-positive reading (indicating that an individual has the disease when this is not the case) and probability 0.10 of giving a false-negative. suppose that ten individuals are tested, five of whom have the disease and five of whom do not. let latex: xx equal the number of positive readings that result.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

y = -1

x = 8

hope this !
