Answer:
The probability that the actual event is less than 6.5 inches is 0.9999.
Step-by-step explanation:
We are given that you have determined that for this gage you have a standard error of 30%.
For a precipitation event of 5 inches, we have to find the probability that the actual event is less than 6.5 inches.
The z-score probability distribution for the normal distribution is given by;
Z = ~ N(0,1)
where, = mean precipitation event = 5 inches
standard error = = 0.30
Now, the probability that the actual event is less than 6.5 inches is given by = P(X < 6.5 inches)
P(X < 6.5 inches) = P( < ) = P(Z < 5) = 0.9999
The above probability is calculated by looking at the value of x = 5 but in the z table the last value of x is given as 4.40 so we take the area of that value only which has an area of 0.9999.
The picture is kind of blurry... but based on what I see the answer is the first one.
Hope this helps!
Let me know if you need anymore help.
Answer:
y=3x+b
Step-by-step explanation:
finding slope:
slope= y2-y1/x2-x1
-2--5/3-2
3/1
slope is 3
i'm not sure how to find the y-intercept using this format but hope this kinda helped!
We are technically FOILing this out... with a power of 3.
(x+y)(x+y)(x+y)
So we can first factor out the first two "x+y"s.
, multiplied by the last "x+y".
Coefficients are the number that comes
in front of a variable. In this case, 1 comes in front of
, 3 comes in front of
, 3 comes in front of
, and 1 comes in front of
.
Thus: 1, 3, 3, 1.
