Answer:
(d) -0.253
Step-by-step explanation:
According to a z-score table for a standard normal distribution, a z-score of -0.25 corresponds to the 40.13th percentile, and a z-score of -0.26 corresponds to the 39.74th percentile.
Interpolating those values gives us the z-score for the 40th percentile. The 40.13th percentile is twice as close to the 40th percentile than the 39.74th, thus:
The answer is (d) -0.253.

Answer:
x=8
x=3
Step-by-step explanation:
f(x) = −4(x − 8)² + 3
h(x)= -(x-3)² + 2
- <em>The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.</em>
f(x) = −4(x − 8)² + 3
for the first function, the vertex is:
- x-8=0 ⇒ x= 8, this is the axis of symmetry
h(x)= -(x-3)² + 2
for the second function, the vertex is:
- x-3= 0 ⇒ x=3, this is the axis of symmetry, it is also visible on the graph
