If you would like to know 52.5% of what number is 25.83, you can calculate this using the following steps:
52.5% of what number is 25.83
52.5% * x = 25.83
52.5/100 * x = 25.83 /*100/52.5
x = 25.83 * 100 / 52.5
x = 49.2
Result: 52.5% of 49.2 is 25.83.
Answer:
From the measure the picture provides us, we can conclude that the prism is a cube, which also tells us that all 6 sides of this prism have equal surface area, so we only need to calculate one of them and multiply the result by 6:
The surface area of one side of the cube should be: 2/3 . 2/3 = 4/9 (ft²)
The surface area of the prism should be: 4/9 . 6 = 24/9 = 8/3 (ft²)
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
