The correct options are:
A. The scatter plot has an outlier at (15, 2)
B. The scatter plot has a cluster with a range from 2 to 4
<u><em>Explanation</em></u>
Co ordinate of any point can be written in form of (x,y) where first value is the distance across x-axis and second value is the distance across y-axis.
We can see in the plot, that the outlier point is 15 unit across x-axis and then 2 unit across y axis from the origin. So the co ordinate of that point will be (15, 2).
Range means the values across the y-axis. We can see that the cluster starts at y=2 and ends at y=4. That means, the scatter plot has a cluster with a range from 2 to 4.
(x+a)^4 = ^4C_0 x^4 + ^4C_1 x^{4-1} a + ^4C_2x^{4-2}a^2 + ^4C_3x^{4-3}a^3 + ^4C_4x^{4-4}a^4
= x^4 + 4x^3a + 6x^2a^2 + 4xa^3 + a^4
Answer:
-15/2 (or -7 1/2)
Step-by-step explanation:
-7.5 is equal to -75/10.
When you simplify it, you get:
-15/2 which simplifies to -7 1/2
Multiply $860 by .11 (11%) to find the answer.

Answer:
(A) -8
Step-by-step explanation:
∆=b^2 -4ac= (-4)^2-4(2)(3)= -8
Since discriminant<0, then the equation has no roots.
