The estimated number of students at the M College who agree climate change is a serious issue is 1759
The percentage of total students is 59.42%
The method used can be biased.
<h3>How many students believe climate change is a serious issue?</h3>
The students surveyed are the sample while the students in the M College are the population. A population is the party of interest in an experiment. A population consists of all the members of the group. A sample is a smaller group of the population.
The limitation of using a sample to estimate for the population is that the sample might be a biased estimate of the population. If the sample is biased, the result of the experiment would be inaccurate.
Estimated number of students at M College = (sample that agree that climate change is a serious problem / total number of people surveyed) x number of students
(205 / 345) x 2960 = 1759
Percentage = (1759 / 2960) x 100 = 59.42%

Quadratic formula: (-b +/- sqrt(b^2 - 4ac)) / 2a
a = 10
b = -1
c = 9
1 +/- sqrt((-1)^2 - 4(10)(9)) / 2(10)
1 +/- sqrt(1 - 360) / 20
x = 1 +/- sqrt(359i) / 20
Hope this helps!
Answer:
It think it is A brainliest?
Step-by-step explanation:
There are no real roots for a negative number, so -81 has no real roots, if the number is 81 however, then the tow roots are 9
Form equation
y = mx + c
y = (rise/run).x + c
y = (11-1 / 3--2)x + c
y = 2x + c
11 = 2(3) + c
Find c (y-intercept)
11 - 6 = c
c = 5
Final equation of line
y = 2x + 5
Substitute given possible x-values in to find y-values
y = 2(1) + 5 = 7 (1,7)
y = 2(2) + 5 = 9 (2,9)
Therefore d is correct
