students were asked in a survey if they like peanuts, cashews, walnuts, or pecans the most. the results are shown in the bar graph.
altogether, how many students participated in the survey?
a.
80
b.
70
c.
35
d.
10

 The correct option is (A) 80.

Step-by-step explanation:  Given that students were asked in a survey if they like peanuts, cashews, walnuts or pecans the most and the results are shown in the bar graph.

We are to find the total number of students that participated in the survey.

From the bar graph, we note that

Number of students who like Peanuts = 15,

number of students who like Cashews = 30,

number of students who like Walnuts = 10

and

number of students who like Pecans = 25.

Therefore, the total number of students that participated in the survey is

Thus, altogether, 80 students participated in the survey.

Option (A) is CORRECT.

c is the correct answer

step-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
