Answer:
The correct answer is;
A. 0.17
Step-by-step explanation:
Here are the provided details;
The average time taken for a cashier to handle an order, μ = 276 seconds
The deviation from the average, σ = 38 seconds
The z-score for an order processing time of x = 240 seconds can be calculated as follows;
Thus;
The resulting probability
P(z = -0.9474) = 0.17361
Hence, the estimated proportion of orders processed in under 240 seconds is roughly 0.17361 or 0.17 when rounded to two decimal places.
Establish a proportion.
8/127=15/x
Cross multiply
8x=1,905
Divide each side by 8
x=238.125
The greatest of the actual distances is 238.125 km.

Answer: a) 
b) 
Step-by-step explanation:
a) To achieve an even total, there are 3 possible combinations:
1) Even, Even, Even, Even 
2) Even, Even, Odd, Odd
3) Odd, Odd, Odd, Odd
Order is irrelevant
Summing these yields your final result: 
b) If one die shows a 2 and another a 3, while the remaining two can show any digits, there’s only one way to get a 2, one way for a 3, and six potential numbers for each of the other two dice.

How quickly is the horizontal distance between the bottom of the pole and... A 176 inch pole is leaning on a wall and is sliding down such that the...
Step-by-step explanation:
The results are as follows: C. Left-handed: 48, Right-handed: 504. D. Left-handed: 30, Right-handed: 315. Explanation: With 58 left-handed and 609 right-handed students at East Middle School, the proportion of students on both hands at West Junior High must match. We can identify viable ratios based on this information. The ratio of right-handed to left-handed students at East Middle School is derived, then examined against the options provided.
