First solve for the trig function 'cot'
Next take the sqrt of both sides (include plus/minus)
Now take reciprocal of both sides, this will change trig function to 'tan'
(cot = 1/tan)
Finally use the unit circle or inverse tan on your calculator to find x.
There will be 4 solutions, one for each quadrant.
Answer:
2+0.15x=3.20
Step-by-step explanation:
So you have the original or starting point $2 which b in y=Mx+b then it’s 0.15 per day but you don’t know how many days so you use x and she owed a total of 3.20

X-intercept (0,4.5)
Y intercept(0,-1)
Answer:
The larger the number of items in the sample, the more closely the distribution of sample items will follow a bell-shaped curve
Step-by-step explanation:
The question is about the distribution of the sample
The sampling distribution, also called the distribution of the sample mean is the distribution for many samples drawn form population at random for large sizes.
As per central limit theorem, if samples of sufficiently large size to represent the population is drawn from the population, the sample means of all sample will follow a normal distribution and hence bell shaped.
So from the options we say a is incorrect because not always
b is incorrect because there is no mention about the chance.
c is incorrect because when we use sample variance we use t test
Option d is correct.
The larger the number of items in the sample, the more closely the distribution of sample items will follow a bell-shaped curve
