Answer:
K = -2
Step-by-step explanation:
If y varies directly as x, k (constant) can be found by dividing the y-coordinate by the x-coordinate.
percent of the observations lie within plus and minus 2.5 standard deviations of the mean is 84%
according to Chebyshev's theorem k=2.5
Chebyshev theorem:
The minimum percentage of observations that are within a given range of standard deviations from the mean is calculated using Chebyshev's Theorem. Numerous other probability distributions can be applied with this theorem. Chebyshev's Inequality is another name for Chebyshev's Theorem.
This indicates that 1 - of the distribution will be close to the mean, or within k standard deviations.
Therefore, 1 -
⇒ 1-
⇒1-
⇒
⇒0.84

ANSWER
shifts up 7 units.
EXPLANATION
The given function is
This is the base of the quadratic function without any transformation.
It is also refer to as the parent function.
The transformed function has equation:
This transformation is of the form
This transformation shifts the graph of the base function up by k units.
Since k=7, the base function is shifted up by 7 units.
