Answer:
Option (1)
Step-by-step explanation:
Parent function for both parabolas graphed is, y = x²
For the large parabola,
This parabola is formed by translating the parent function 4 units downwards.
So the equation will be, y = x² - 4
Now graph of the inequality shows the dotted line with shaded area inside the parabola,
Equation of the parabola will be,
y > x² - 4
Similarly, equation of the other parabola will be,
y < x² + 6 [Since shaded region is the region outside the dotted lines of the parabola]
So the system of inequalities will be,
y > x² - 4
y < x² + 6
Therefore, Option (1) will be the answer.
Answer:
The value for the test statistics = 3.48
Step-by-step explanation:
Given that:
population mean = 75
sample size n = 25
sample mean = 78.48
standard deviation = 5
The value for the test statistics can be computed by using the formula:
z = 3.48
The value for the test statistics = 3.48
Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
