Answer:
Percentage of his gross pay which is take-home pay is 80.35%.
Explanation:
Step-by-step explanation:
Assuming the data is as shown, restaurant X has a mean service time of 180.56, with a standard deviation of 62.6.
The standard error is SE = s/√n = 62.6/√50 = 8.85.
At 95% confidence, the critical value is z = 1.960.
Therefore, the confidence interval is:
180.56 ± 1.960 × 8.85
180.56 ± 17.35
(163, 198)
Restaurant Y has a mean service time of 152.96, with a standard deviation of 49.2.
The standard error is SE = s/√n = 49.2/√50 = 6.96.
At 95% confidence, the critical value is z = 1.960.
Therefore, the confidence interval is:
152.96 ± 1.960 × 6.96
152.96 ± 13.64
(139, 167)
Answer:
The total number of integers between 2020 and 2400 have four distinct digits arranged in increasing order is 15.
Explanation:
Given :
Numbers -- 2020 and 2400
The following steps can be used in order to determine the total number of integers between 2020 and 2400 have four distinct digits arranged in increasing order:
Step 1 - According to the given data, there are two numbers 2020 and 2400.
Step 2 - So, the integers having four distinct digits arranged in increasing order are:
2345, 2346, 2347, 2348, 2349, 2356, 2357, 2358, 2359, 2367, 2368, 2369, 2378, 2379, and 2389.
Step 3 - So, the total number of integers between 2020 and 2400 have four distinct digits arranged in increasing order is 15.
The correct answer is April 10th.
