Answer:
$37
Step-by-step explanation:
//You need to factorise the two quadratics and divide where possible
x^2 + 3x + 2 = (x+2)(x+1)
x^2 - 4 = (x+2)(x-2)
y = (x+2)(x+1)/(x+2)(x-2)
y = (x+1)/(x-2)
Answer:
-2, -1
Step-by-step explanation:
B is the answer for you. Have a good day!
Based on the calculations, the correct value of the test statistic is equal to 3.2.
<h3>How to calculate value of the test statistic?</h3>
For samples A and B, the hypothesis is given by:
H₀: μ₁ ≤ μ₂
H₁: μ₁ > μ₂
Since both samples have a normal distribution, we would use a pooled z-test to determine the value of the test statistic:
Substituting the given parameters into the formula, we have;
z = 3.2.

Answer:
p = -30
Solution :
swap the sides
0.15p = -4.5
divide both sides of the equation with 0.15
p = -30
