Answer:
divide by 4, 12, 21
Step-by-step explanation:
first, look at 20, and 5. How do you get there?
well, there are 2 possible ways.
20/4=5, or 20-15=5
we take it into the next pattern to get
44/4=11, and 44-15=29.
so now we know that the rule is to divide by 4
____________________________________________
36/4 = 12
84/4=21
The point translated up 7 and left 3. This will cause the point to go from (-3,7) to (-6,14)
Answer:
Mailing preparation takes 38.29 min max time to prepare the mails.
Step-by-step explanation:
Given:
Mean:35 min
standard deviation:2 min
and 95% confidence interval.
To Find:
In normal distribution mailing preparation time taken less than.
i.eP(t<x)=?
Solution:
Here t -time and x -required time
mean time 35 min
5 % will not have true mean value . with 95 % confidence.
Question is asked as ,preparation takes less than time means what is max time that preparation will take to prepare mails.
No mail take more time than that time .
by Z-score or by confidence interval is
Z=(X-mean)/standard deviation.
Z=1.96 at 95 % confidence interval.
1.96=(X-35)/2
3.92=(x-35)
X=38.29 min
or
Confidence interval =35±Z*standard deviation
=35±1.96*2
=35±3.92
=38.29 or 31.71 min
But we require the max time i.e 38.29 min
And by observation we can also conclude the max time from options as 38.29 min.
Answer:
The solutions to the equation are 1, 0.375.
Step-by-step explanation:
The equation is already in factored form.
The solutions to the system are the values of x that make one or the other of the factors be zero.
x -1 = 0 . . . when x = 1
8x -3 = 0 . . . when x = 3/8 = 0.375
There is only one variable, so no "ordered pairs" are involved.
The solutions are {1, 0.375}.
