A vaccine, which is currently in use, is known to be 80% effective. A pharmaceutical company has developed a newvaccine and the
storchak [24]

Answer:

The correct answer is B) 18%

Step-by-step explanation:

Note that the vaccine is already and is 80% effective. This means that if the entire population was administered with the vaccine, only 8/10 would gain immunity leaving 2/10 or 0.2 exposed.

If the new vaccine, therefore, is supposed to be 90% effective, it is only pragmatic to administer it against those who do not have immunity which is 0.2 of the existing population.

So to get the percentage that will develop immunity, we have:

0.2 x 0.9 = 0.18 or 18%

Cheers!

Ron bought a keychain for $7 and 3 t-shirts. He spent a total of $37. How much does each t-shirt cost?
White raven [17]

Answer:

$10

Step-by-step explanation:

Subtract the price of the keychain, $7, from the total to find the price of the 3 t-shirts:

$37 - $7 = $30

The 3 t-shirts cost a total of $30.

We assume all t-shirts have the same price.

price of 1 t-shirt = $30/3 = $10

Answer: $10
