In a survey of 1,800 people who owned a certain type of car, 900 said they would buy that type of car again. What percent of people surveyed were satisfied with the car?

50%

Step-by-step explanation:

Since 900 is half of 1800, that means half of the people surveyed were satisfied.

As a percent, half is represented by 50%

So, 50% of the people surveyed were satisfied with the car

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x
