Thus, there are five distinct flavors. A group of 180 individuals was surveyed. Accordingly, the null hypothesis suggests no significant difference, with each flavor receiving 180/5 = 36 counts. x^2 =
. Here, mi indicates the expected frequency based on the hypothesis, which is 36, n = 180, and xi corresponds to the actual observations. By substituting the known values, we find that x^2 = 9. The level of association is expressed as
. This results in approximately 0.10, which surpasses our threshold.
5(x^2+8x)=14
5(x^2+8x+16)=5(x^2+8x)+5*16=5(x^2+8x)+80=14+80=94
The correct choice is the second one
Answer:
The provided radical equation has no solution.
x = 225/16 is not a valid solution.
Step-by-step explanation:
The given equation is
Add 3 to both sides of the equation
Squaring both sides
Divide both sides by 16
Check by substituting the value of x back into the original equation to confirm the extraneous solution.
Since -18 is not equal to 12, thus the value of x fails to satisfy the equation.
Consequently, x = 225/16 is an extraneous solution.
Step-by-step explanation:
