Step-by-step explanation:
Answer:
C.) X=3 and X=-6/7
Step-by-step explanation:
Use the quadratic formula to solve
So plug in 10 for r which would give you 3(10)=10+5s the multiply 3x10 so you should have 30=10+5s you want to get 5s by its self to subtract 10 to both sides so you should get 20=5s them divide 5 to both sides and you get s=4
Answer:
A. Use the two-sample t-methods when a sample was taken from each of two populations (i.e. two groups being compared) and the population standard deviations are not known.
Step-by-step explanation:
T-distribution:
When the population standard deviation is not known, the t-distribution is used.
If a sample was taken from one population, we use the one-sample method, while if there is a comparison of two populations, the two-sample method is used, and thus, the correct answer is given by option A.
