The probability of s<span>electing 2 fully charged batteries in a row from a large batch in which 6% of the batteries are dead is given by:
</span>
The percent of change would be -33.3% which would then equal a 33.3% decrease (when decimal is rounded)
what I did was turn 1/4 and 1/2 into decimals to make it easier to solve
Answer: 162.00 or 40.50 or 202.50
Step-by-step explanation:
$6.75 times 30 = 202.50
202.50 times 0.2 = 40.50
202.50 minus 40.50 = 162.00
The general formula for a equation of the form:
is:
In this case we notice that a=1, b=-4 and c=3. Plugging this values in the general formula we get:
then:
and
Therefore, x=3 or x=1.
