Answer:
15$
Step-by-step explanation:
Answer:
Each time, the x is being multiplied by -3 to result in the output.
So for every x input, multiply by -3.
For the y output for 15, you would divide by -3 to find the input x
For example, when 7 is the input, multiply by -3, and the output y would result in -21.
The number of solutions of the system of equations is 904 086
Answer:
The p-value is 0.0229
Step-by-step explanation:
With we have an upper-tail alternative. Because the p-value is defined as the probability of getting a value at least as extreme as the value observed. The observed value is given by the test statistic z = 1.997 which comes from a standard normal distribution. Therefore, we compute the p-value in the following way P(Z > 1.997) = 0.0229, i.e., the p-value is 0.0229
