Answer:
3,-2
Step-by-step explanation:
set y =0 and solve
(-x-2)(x-3)=0
the values 3, -2 solve the equation and are your x-intercepts
Answer:
a reflection across line y, then a translation (1,-5) (right 1, down 5)
Step-by-step explanation:
A(-2,4) → (2, 4) → D(3, -1)
B(-6, 1) → (6, 1) → E(7, -4)
C(-3, 1) → (3, 1) → F(4, -4)
D=122 degrees, hope this helps!!
Answer: The standard deviation was calculated incorrectly.
Step-by-step explanation:
- The standard deviation measures the dispersion of the data values from the mean value.
It cannot be negative , because it is the square root of the variance .
We add all squared deviations from the data points away from the mean and (then divide it by the number of data values) to evaluate variance.
Since , any squared number cannot give a negative result.
⇒ Standard deviation cannot be negative.
⇒The standard deviation was calculated incorrectly.
Rest other things (given in options) can not be interpreted on the basis of given information.
