Step-by-step explanation:
Answer:
X=7 is a solution
X= -2 is an extraneous solution.
Step-by-step explanation:
Answer:
.023------ 7/30
.4------ 4/9
1.6----- 5/3
3.5------ 32/9
All I did was divide each fraction (the numerator by the denominator) and use the answer I got to match the fraction with the decimal.
hope this helps!
These are the events in the question above:
<span>D - has disease
</span>
<span>H - healthy (does not have disease)
</span>
<span>P - tests positive </span>
<span>It is the probability that a person has the disease AND tests positive divided by the probability that the person tests positive.
</span>
Sick, + [.04*.91] = .0364
<span>Sick, - [.04*.09] = .0036 </span>
Healthy, + [.96*.04] = 0.0384
<span>Healthy, - [.96*.96] = .9216
</span>
.0364 / (.0364 + .0.0384) = 0.487
Answer:
y=x-8 and y=-x+4
Step-by-step explanation:
The slopes of the lines can be anything, as long as they are the opposite reciprocals of each other. Then you can plug in the point for x and y to solve for b in both lines (for y=mx+b where m is the slope)
