b = 6
Step-by-step explanation:
Cross multiply: 39(b) = (26)(9)
39b = 234
Divide both sides by 39
b = 6
Both methods assume a normal distribution of the data, but the z-tests are most useful when the standard deviation is known.
OR u can use , z-tests are used when we have large sample sizes (n > 30), whereas t-tests are most helpful with a smaller sample size (n < 30). Both methods assume a normal distribution of the data, but the z-tests are most useful when the standard deviation is known.
Answer:
The answer is f(x), because it grows slower than g(x).
Step-by-step explanation:
f(x) is a quadratic function (because as you can see the formula of f(x) is x^2 + 2). The function of g(x) is exponentional, and therefore it grows faster than f(x).
