In a survey of 2300 people who owned a certain type of​ car, 460 said they would buy that type of car again. What percent of the
JulsSmile [24]

Answer:

The survey shows that 20% of the individuals were satisfied with the car.

Step-by-step explanation:

  • We are given that 2,300 people were surveyed.
  • We are also given that 460 of those individuals would buy that car again.
  • We need to find the percentage of individuals that were satisfied with the car.

When we need to find the percentage of a population, we can use the following formula:

  • \displaystyle \frac{\text{part}}{\text{whole}} \times 100

We need to identify the part and the whole in this problem.

We are given that 2,300 people are surveyed, so this is the <u>whole</u> portion.

We are also given that 460 were satisfied, so this is the <u>part</u> portion.

Therefore, we can set up our fraction.

  • \displaystyle \frac{460}{2300}

Now, let's solve the percentage.

\displaystyle \frac{460}{2300} \times 100\\\\\frac{2}{100} \times 100 = 20\%

Therefore, of those surveyed, 20% of the individuals were satisfied with the car.

- Three people examine the system of linear equations shown.
Makovka662 [10]

Answer:

there are no solutions as the two straight lines represented by the two equations are parallel, so they have no point in common

Step-by-step explanation:

general equation of a straight line: ax + by + c = 0

the slope (or raise) of a straight line m is equal to -a/b (b=1 a=-2 in this exercise as the equation is 1y=-2x - 4)

so m1 = -2/1 = -1/2

and m2 = -2/1 = -1/2

there is also a geometrical explanation, but I am not sure if it could be too complex
