Answer: 56 minutes</h3>
1 hour = 60 minutes
The time values given, in minutes, are:
25, 55, 60, 94, and 46
going from monday to friday in that exact order
Add up the values, then divide by 5. This is because there are 5 values
So adding up the values gets us: 25+55+60+94+46 = 280
Then dividing by 5 leads to this answer: 280/5 = 56
note: you must convert the "1 hour" to "60 minutes" because each time value must be in the same units. Otherwise, its like mixing apples and oranges which makes no sense.
1st) 275+70-50 Lastly: Subtract -350 - 295 = - 55
275+70 = 345 The answer is - 55
345 - 50 = 295
Answer:
a. 0.71
b. 0.9863
Step-by-step explanation:
a. From the histogram, the relative frequency of houses with a value less than 500,000 is 0.34 and 0.37
-#The probability can therefore be calculated as:
Hence, the probability of the house value being less than 500,000 is o.71
b.
-From the info provided, we calculate the mean=403 and the standard deviation is 278 The probability that the mean value of a sample of n=40 is less than 500000 can be calculated as below:
Hence, the probability that the mean value of 40 randomly selected houses is less than 500,000 is 0.9863
The answer to this subtraction is d
