13. 1
14. 1
15. any number and 0 will have a quotient of 0.
for example 7/0=0 . 8/0=0 . 9/0=0
if you try and check your work using multiplication 7*0=0 . 8*0=0 . 9*0=0
then you will realize the rule is right
Answer:
Your answers may vary slightly. 5.2 Normal Distributions: Finding Probabilities If you are given that a random variable Xhas a normal distribution, nding probabilities corresponds to nding the area between the standard normal curve and the x-axis, using the table of z-scores. The mean (expected value) and standard deviation ˙should be given
Step-by-step explanation:
The probability of drawing a white marble =
∴ the probability of drawing a white marble = ³/₁₄
A vertical line has the equation of x = a
If the vertical line goes through a certain point, as in this case, then the y value is irrelevant. It can be anything. It is the x value that is the one you need to use.
So the answer is x = 1. This equation has no slope that is defined.
The answer is 244 because you add 35 to 287 then subtract 78 and it equals 244
