The <em>correct answer</em> is:
b.) –0.507x2 + 14.907x – 36.131
Explanation:
First we enter the data into a graphing calculator. The times are the x-coordinates and the temperatures are the y-coordinates; this is because temperature is dependent upon time.
After we enter this, we run a regression on the calculator. We will run the quadratic regression; the equation is of the form
y = ax²+bx+c.
The values we are given on a Casio fx-9860 gii are:
a = -0.507
b = 14.908
c = -36.136
This is closest to choice B.
Answer:
9, 12, -5
Step-by-step explanation:
Let us move all the terms to one side.
9x^2+12x-5=0
Therefore, using the quad formula of ax^2+by+c=0,
a=9
b=12
c=-5
Hope this helps! :)
Answer: 0.965
Step-by-step explanation:
Given : Water use in the summer is normally distributed with
Let X be the random variable that represents the quantity of water required on a particular day.
Z-score : 
Now, the probability that a day requires more water than is stored in city reservoirs is given by:-
We can see that on comparing the above value to the given P(X > 350)= 1 - P(Z < b) , we get the value of b is 0.965.
I believe the answer is B.) 9and27/32
Best of luck.
Answer:
answer is 27 hope it helps
