Answer:
The required range of the function
is [-7,-1]
Step-by-step explanation:
Given : Function ![y=-3\sin (x)-4](https://tex.z-dn.net/?f=y%3D-3%5Csin%20%28x%29-4)
To find : What is the range of the given function?
Solution :
The range is defined as the variation in which any function is defined.
We know that the sin function lies between [-1,1]
.....(1)
The required function is ![y=-3\sin (x)-4](https://tex.z-dn.net/?f=y%3D-3%5Csin%20%28x%29-4)
Multiply equation (1) by -3
.....(2)
Now, we subtract equation (2) by 4
Therefore, The required range of the function
is [-7,-1].

Answer: p → POPULATION PROPORTION
Step-by-step explanation:
Given : n 1987, the General Social Survey asked, "Have you ever been active in a veteran's group? "
Sample size : n= 98
Proportion of successes = 52
The confidence interval for p is given by :-
![p\pm\ z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}](https://tex.z-dn.net/?f=p%5Cpm%5C%20z_%7B%5Calpha%2F2%7D%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
Where p is population proportion of successes.
So the parameter is p → POPULATION PROPORTION
Answer:
B.
Step-by-step explanation:
process of elimination. the red dot is not a 1/4 of the number of lines, so it cant be 12.25, 13.625 is impossible because it has a value less than 13, and 12.625 is impossible as well because it has a value less than 12.5 therefore 12.375 is the best answer, and the only correct answer
