Answer:
The p-value is;
d. 0.00131
Step-by-step explanation:
The given question parameters are;
Company A Company B
Sample size 80 60
Sample mean $16.75 $16.25
Population standard deviation σ₁ $1.00 σ₂ $0.95
Therefor, we have;
The p-value = 1 - 0.99869 (the area to the right of 3.01) = 0.00131
An angle is denoted by the angle symbol ∠ and the three letters representing the name of the angle.
An angle is denoted by the angle symbol ∠ which is then being followed by three letters that will represent the points that form an angle.
Lets say for example, the expression ∠ABC will mean that “the angle is formed by the points A, B and C”
where the vertex of the angle is at the point B as it is in the middle.
Angles can also be of different types like:
An Acute Angle which means an angle is less than 90 degrees.
A Right Angle which means an angle which is exactly 90 degrees.
An Obtuse Angle which is an angle more than 90 degrees and less than 180 degrees.
A Straight Angle which is an angle that is exactly 180 degrees.
And a Reflex Angle which is an angle greater than 180 degrees and less than 360 degrees.
Therefore, an angle is denoted by the angle symbol ∠ and the three letters representing the name of the angle.

Answer:
f(-5) = 23
Step-by-step explanation:
Step 1: Define
f(-5) = x = -5
f(x) = -4x + 3
Step 2: Substitute
f(-5) = -4(-5) + 3
Step 3: Evaluate
f(-5) = 20 + 3
f(-5) = 23
