Answer:
61 is the rate at which the population changes every year
Step-by-step explanation:
Given
Required
Interpret 61
A linear equation has the form:
or
Where m is the rate
By comparison:
Hence, 61 represents the rate at which the population changes yearly.
<em>The negative sign implies that the populatiin reduces</em>
The answer for this question is number 2. 125
C bc the x is where the right angle is and the 2 sides of a right angle is going to be equal
We are interested in the left-end area under the standard normal curve that has the area 0.025.
But the problem seems to be simpler than that:
If n = number of students in the class, and we know that 2.5% of these students failed the course, and that 5 failed, then we can surmise that
0.025n = 5. Solving for n by multiplying both sides by 40, we get n = 200.
There were 200 students in the class.
It is perfectly fair for a teacher to put more info into a problem statement than you really need to solve the problem. That seems to be what happened here.
