Answer: The answer is 46.5 inches to 49.5 inches.

Step-by-step explanation: We are to tell the height limits of a 7-year old child.

Various scientific experiment shows that the height of maximum 7-year old girl child lies between 46.5 inches and 49.4 inches and the height of maximum 7-year old boy child lies between 46.6 inches and 49.5 inches.

So, combining the height limits of girls and boys, we can say that the height limit of 95% 7-year old child lies between 46.5 inches and 49.5 inches.

Thus, the answer is 46.5 inches and 49.5 inches.

Parking spaces at a business school are arranged by a random monthly lottery. there are 3 spaces for every 10 students who want
Alexus [3.1K]

27.034%  
Let's define the function P(x) for the probability of getting a parking space exactly x times over a 9 month period. it would be: 
P(x) = (0.3^x)(0.7^(9-x))*9!/(x!(9-x)!)  
Let me explain the above. The raising of (0.3^x)(0.7^(9-x)) is the probability of getting exactly x successes and 9-x failures. Then we shuffle them in the 9! possible arrangements. But since we can't tell the differences between successes, we divide by the x! different ways of arranging the successes. And since we can't distinguish between the different failures, we divide by the (9-x)! different ways of arranging those failures as well. So P(4) = 0.171532242 meaning that there's a 17.153% chance of getting a parking space exactly 4 times. 
Now all we need to do is calculate the sum of P(x) for x ranging from 4 to 9.

So
 P(4) = 0.171532242
 P(5) = 0.073513818
 P(6) = 0.021003948
 P(7) = 0.003857868
 P(8) = 0.000413343
 P(9) = 0.000019683
  And
 0.171532242 + 0.073513818 + 0.021003948 + 0.003857868 + 0.000413343
+ 0.000019683 = 0.270340902 
 So the probability of getting a parking space at least four out of the nine months is 27.034%

Which expression will calculate the distance<br> between any two points (p and q) on a number line?
aleksley [76]

Answer:

The answer is (A)

Step-by-step explanation:

By subtracting both number you will be left off with the distance between the numbers.

Edit: answer (C) is wrong because it refers to the absolute values of p and q, the absolute value of a number is equal to how many numbers that number is away from zero.
