Answer:
y = -2x + 8
Step-by-step explanation:
The point slope form of an equation is written as
y = mx + c ...............(i)
Where m is the slope and c is the constant
Now we Know that the equation is
y + 2 = -2(x-5)
and the given points are
m= -2
x = 5
and y= -2
Putting these values in equation (i) to find the value of c
y = mx + c
it becomes
-2 = -2(5) + c
-2 = -10 + c
Adding 10 on both sides
-2 + 10 = -10 + 10 + c
8 = c
or c=8
Now we have the values of m and c
where m= -2 and c = 8
Point slope form of an equation is
y = mx + c
putting the values of m and c to get equation in slope intercept form is
y = (-2)x + 8
or
y = -2x + 8
Other method:
The given point slope form is
y + 2 = -2(x-5)
We have to change it in y= mx + c form
so solving it
y + 2 = -2x + 10
Subtracting 2 from both sides
y + 2 -2 = -2x + 10 -2
y = -2x + 8
which is same is
y=mx + c
so the required equation is
y = -2x + 8
Answer:
68% of plans cost between $62.16 and $86.52.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean: 74.34
Standard deviation: 12.18
Bell-shaped is the same as normally distributed.
Estimate the number of plans that cost between $62.16 and $86.52.
62.16 is one standard deviation below the mean.
86.52 is one standard deviation above the mean.
By the Empirical rule, 68% of the measures are within 1 standard deviation of the mean.
So
68% of plans cost between $62.16 and $86.52.
Answer:
Neither
Step-by-step explanation:
Neither because sometimes as x increases, y increases and sometimes as x increases, y decreases so this graph have no corrleation so it neither.
Sin50° = BC/3
3sin50° = BC
BC = 2.981
Hope this helped!
