I am going to go with the assumption that your equation is
. If there is only one solution, then the equation must be a perfect square. So square
to solve for the equation in the similar form that is given.
. So the variables match up perfectly in the equation, meaning that the value of m is 6, letter choice C.
Answer:
:P
Step-by-step explanation:
To simplify this ration we need to divide each member of ration with same number.
We can start with 2.
18/2: 30/2 : 72/2 or
9:15:36
Now we can divide by 3 because 15 isn't divisible by 2.
we get:
3:5:12
This ration cannot be simplified further.
The equation in y = mx+b form is y = -450x+2745
where,
x = number of hours that have passed by
y = distance to destination in miles
The y intercept is 2745 since this is the initial starting y value, aka the starting distance. Therefore b = 2745.
The slope is -450 or -450/1 since for each hour, the distance goes down by 450. You can think of it as
slope = (change in y)/(change in x)
slope = (change in distance)/(change in time)
slope = (-450 miles)/(1 hour)
slope = -450
Answer:
we can not reject any value
Step-by-step explanation: From data we can test the highest and the lowest value to evaluate if one of these values are out of certain confidence Interval
If we established CI = 95 % then α = 5 % and α/2 = 0,025
From data we find the mean of the values
μ₀ = 12,03 and σ = 0,07
From z table we find z score for 0,025 is z(c) = ± 1,96
So limits of our CI are:
12,03 + 1,96 = 13,99
12,03 - 1,96 = 10,07
And all our values are within ( 10,07 , 13,99)
So we can not reject any value
