In Canada, households spent an average of $80.63 CDN monthly for high-speed broadband access.24 Assume that the standard deviati
ELEN [110]

Answer:

Step-by-step explanation:

Assuming a normal distribution for the amount spent by Canadian households for high-speed broadband access, the formula for normal distribution is expressed as

z = (x - u)/s

Where

x = amount spent by the Canadian households.

u = mean amount spent monthly.

s = standard deviation

From the information given,

u = $80.63 CDN

s = $27.32 CDN

We want to find the probability that the average amount will exceed $85. It is expressed as

P(x greater than 85) = 1 - P(x lesser than or equal to 85)

For x = 85

z = (85 - 80)/27.32 = 0.18

Looking at the normal distribution table, the corresponding z score is 0.57142

P(x greater than 85) = 1 - 0.57142 = 0.43

If you need to write a do-while loop that will ask the user to enter a number between 2 and 5 inclusive, and will keep asking un
Iteru [2.4K]

Answer: (2 > number || number > 5)

Step-by-step explanation:

The do-while loop need to work until the user enters a correct number. In this case the number need to be between 2 and 5 inclusive.

On the opposite, if the user enters a number between 2 and 5 inclusive, he will leave the do-while loop.

Here is how it works : Once the user enters a number, the do-while loop will check this number.

If the number is NOT between 2 and 5 inclusive, the do-while loop will ask again the user to enter a number.

If the number is between 2 and 5 inclusive, the loop stop working.

So the do-while loop need to check if the number IS NOT between 2 and 5 inclusive.

If it is not between 2 and 5 inclusive, it could be :

Smaller than 2 : number < 2

Or greater than 5 = number > 5

The "or" condition is written by the symbols "||".

The loop condition is (2 > number || number > 5).
