How many students were surveyed about their mode of transportation to school?

AlekseyPX

Answer:

Total number of students surveyed about their mode of transportation to school is 400.

Step-by-step explanation:

Here, given student who uses car as their mode of transport = 120 students

We have to find the total number of students who are surveyed.

Also, since complete circle represents 100% of data,

Total students who uses at least one mode of transport out of foot, bicycle, bus or car let it be x students.

Total percentage of students that uses bus, bicycle and on foot = (20 +15+35)% = 70%

Thus, percentage of students that uses car = 100 - 70 = 30%

Thus, 30 % of total students = 120

Mathematically, 30% of x = 120

Solving for x, we get,

$\frac{30}{100} \times x=120$

$\Rightarrow x=120 \times \frac{100}{30}$

$\Rightarrow x=400$

Thus, total number of students surveyed about their mode of transportation to school is 400.

Let f(x)=3x^2+5 . The quadratic function g(x) is f(x) translated 3 units up. Enter the equation for g(x) in the box. g(x) =

Phantasy [73]

Answer: $g(x)=3x^2+8$

Step-by-step explanation:

There are some transformations for a function $f(x)$ . Two of those transformations are:

1. If $f(x)+k$ , then the function is translated "k" units up.

2. If $f(x)-k$ , then the function is translated "k" units down.

In this case, you have the following Quadratic function $f(x)$ given in the exercise:

$f(x)=3x^2+5$

According to the information given, the function $g(x)$ is obtained by translating the Quadratic function $f(x)$ 3 units up. Based on this, you can identify that the transformation is the following:

$f(x)+k$

Where $k=3$

Therefore, you can determine that:

$g(x)=f(x)+3=3x^2+5+3\\\\g(x)=3x^2+8$
