Given:
x lies in the III quadrant.
To find:
The values of .
Solution:
It is given that x lies in the III quadrant. It means only tan and cot are positive and others are negative.
We know that,
x lies in the III quadrant. So,
Now,
We know that,

Answer:
13 weeks.
Step-by-step explanation:
equation type is y=mx+b
b=60
m=5
x=how many weeks
y=125
125=5x+60
-60
125-60=65
65=5x
65/5=13
Answer: 141
Step-by-step explanation:
Let p be the population proportion of adults over 50 never graduated from high school.
As per given , we have
Prior estimate of proportion for adults with 5 to 30 age graduated from high school group : p= 0.25
Significance level :
Critical z-value :
Margin of error : E= 0.06
Sample size will be :-
Simplify ,
Hence, the required sample size younger age group be surveyed = 141
