En un hospital 1800 varones mayores de 40 años son examinados por medio del tacto rectal como prueba de tamizaje para detectar cáncer de próstata, de los cuales resultan 750 con agrandamiento sospechoso y 1050 sin agrandamiento.. Tabla de contingencia.

Resultado de biopsia prostatica.

CÁNCER BENIGNO TOTAL

-Agrandamiento. 630.(cáncer) 120. (benigno) 750(total)

-Sin agrandamiento 220.(cáncer) 830. (benigno) 1050(total)

Total. 850.(total de cáncer) 950. (total de benigno) 1800(total)

Cuál es la probabilidad si...

Él tacto rectal detecte agrandamiento?

El tacto rectal resulte sin agrandamiento y de que la biopsia informe benigno?

El t rectal detecte agrandamiento o de que el diagnóstico final sea cáncer?

El tacto rectal informe agrandamiento dado que el paciente realmente tiene cáncer?

El tacto rectal indique "sin agrandamiento" dado que es benigno?

El paciente tenga cáncer dado que el tacto rectal informó Agrandamiento?

El paciente esté sano (benigno) dado que el tacto r informa sin agrandamiento?

Solve -.016x= -16. need solving this

One of the complementary angles is 4 degrees mor than the other. find the angles (recall that complementary angles are angles whose sum is 90 degrees.) which of the following can not be used to solve the problem if x represents one of the angles? a. 2x-4=90 b. 2x+4=90 c. x+4=90

Submarines control how much they float or sink in the ocean by changing the volume of air and water contained in large ballast tanks. when the tanks are completely full of water, the submarine increases its overall mass and sinks down to the bottom. when the tanks are completely full of air, the submarine reduces its overall mass and floats to the surface. depending on the density of the seawater surrounding the submarine, it will pump seawater in or out of the tanks in order to achieve the same overall density as the sea water and float neutrally in the water. the volume of the submarine never changes. when the tanks are completely full of water, a submarine with a volume of 7.8\times10^3\text{ m}^37.8×10 3 m 3 7, point, 8, times, 10, start superscript, 3, end superscript, space, m, start superscript, 3, end superscript has a total mass of 8\times10^6\text{ kg}8×10 6 kg8, times, 10, start superscript, 6, end superscript, space, k, g. the density of the seawater is 10^3\text{ kg/m}^310 3 kg/m 3 10, start superscript, 3, end superscript, space, k, g, slash, m, start superscript, 3, end superscript. to make that submarine float neutrally, and neither float nor sink in the ocean, what volume of water does that submarine need to subtract from its tanks?
