Answer:
d. Twenty-five cars are randomly selected with the new transmission and 25 with the old transmission.
Step-by-step explanation:
A hypothesis test on the difference between the means must satisfy the following conditions
1) the samples must be randomly selected
2) each sample must have a known standard deviation
3) the samples must be independent
4) the samples must be from normal distribution
Hence only part d gives the right answer.
Answer:
x = -1
Step-by-step explanation:
Both tables show a function value of 9 for x = -1.
x = -1 is the solution to f(x) = g(x), since f(-1) = 9 = g(-1).
Answer:
3.93 (approx.)
Step-by-step explanation:
3 ^ x + 6 = 3 ^ 4 can be rewritten as 3 ^ x = 3 ^ 4 - 6, or
3^x = 81 - 6 = 75.
Then 3^x = 75, or
x*ln 3 = ln 75
Solving for x:
x = (ln 75) / (ln 3) = 3.93 (approx.)
Step-by-step explanation:
GIVEN: O is the mid point of AC & BD.
Therefore, AO = CO & BO = DO
