Answer:
The solution to the inequality is
x > 2π
Step-by-step explanation:
Given the inequality :
2 - 3cscx > 8
We want to find the solution to this.
2 - 3cscx > 8
-3cscx > 8 - 2
-3cscx > 6
cscx < -2
But cscx = 1/cosx
1/cosx < -2
cosx > -1/2
x > arccos(-1/2)
x > 2π
Answer:
D) a chi square test for independence.
Step-by-step explanation:
Given that we suspect that automobile insurance premiums (in dollars) may be steadily decreasing with the driver's driving experience (in years), so we choose a random sample of drivers who have similar automobile insurance coverage and collect data about their ages and insurance premiums.
We are to check whether two variables insurance premiums and driving experience are associated.
Two categorical variables are compared for different ages and insurance premiums.
Hence a proper test would be
D) a chi square test for independence.
