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%

#SPJ1
x⁴ + x = 0
x(x³) + x(1) = 0
x(x³ + 1) = 0
x = 0 or x³ + 1 = 0
- 1 - 1
x³ = -1
x = -1
It's going to be going up. That means the answer is b.
Hope this helped☺☺
Well let's say x = -1000
That's what I would do
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
