Answer:
4x-12
Step-by-step explanation:
use distributive property and distribute the 4 through
Discriminant, D = b² - 4ac
x² - 4x + 5 = 0 comparing to ax² + bx + c = 0
a = 1, b = -4, c = 5
D = b² - 4ac = (-4)² - 4*1*5 = 16 - 20 = -4
In taking the square root of the discriminant of -4, √-4 = 2i = Not Real. So:
Discriminant is -4, so the equation has no real roots.
The second option is correct.
Answer:
"0.0373" seems to be the appropriate solution.
Step-by-step explanation:
The given values are:
n₁ = 43
n₂ = 35




Now,
The test statistic will be:
⇒ 
On substituting the given values in the above formula, we get
⇒ 
⇒ 
⇒ 
⇒ 
then,
P-value will be:
