Sixty-four percent of the students correctly described the process of photosynthesis. If 63 students did not correctly describe
olganol [36]

Answer:

Number of students who correctly describe the process = 112 students.

Step-by-step explanation:

<em>From the information provided in the question;</em>

<em>64% correctly described the process of photosynthesis.</em>

<em>63 students didn't describe correctly the process of photosynthesis.</em>

We are to find the number of students that did correctly describe the process of photosynthesis.

First of all we need to find the total number of students.Lets represent this value to be x

percentage of students who incorrectly describe the process = (100-64)%

=36%

\frac{36}{100}*x =63

x= 63*100/36

x=175 students.

FIRST METHOD

Number of students who correctly describe the process = \frac{64}{100}*total number of students

= \frac{64}{100}*175

Number of students that correctly describe the process = 112 students.

SECOND METHOD

Number of students who correctly describe the process =  Total number of students- number of students who didn't correctly describe the process

Number of students who correctly describe the process = 175-63

Number of students who correctly describe the process = 112 students.

Looking at the graph, we can say that 40% of the people rode the bus. We also know that 80 people took the survey.

  • => 2 x 16
  • => 32 people
