VladimirAG [237]

Answer:

The cost of the television is $\$294$

Step-by-step explanation:

Let

x -----> the cost of the television in dollars

we know that

The cost of the television represent 100%

If Matt pays cash

then

$100\%-7\%=93\%=93/100=0.93$

The cost is 0.93x

If Matt pays with a loan

then

$100\%+10\%=110\%=110/100=1.1$

The cost is 1.1x

The difference between the two methods is

$1.1x-0.93x=0.17x$

Remember that

The difference between the two methods is $49.98

$0.17x=49.98$

Solve for x

$x=\$294$

IgorLugansk [536]

If 25% of the people are vaccinated, then 75% of the people are not vaccinated. Of those not vaccinated, each has a 50% chance of contracting the disease. The probability that someone is both not vaccinated and contracts the disease is (0.75)(0.5)=0.375.
The probability that someone is vaccinated and contracts the disease is (0.25)(0.1)=0.025 (it is multiplied by 0.1 because if the vaccine is 90% effective, then there is a 10% chance someone that is vaccinated can contract the disease.
Add these together for the total: 0.375+0.025=0.4
There is a 40% chance that someone chosen at random will contract the disease.
