Answer:
Null hypothesis: H₀: ∪ = ≤ 393 pounds
Alternative hpothesis Hₐ: ∪ > 393 pounds
Step-by-step explanation:
The null hypothesis in this case is
Null hypothesis: H₀: ∪ = ≤ 393 pounds
Agriculture Scientists wish to test against this claim believing that the new fertilizer may increase the yield, thus the alternative hypothesis will be
Alternative hpothesis Hₐ: ∪ > 393 pounds.

Answer:
Option C
23.08% markup on selling price.
Step-by-step explanation:
Given in the question,
markup percentage on cost price = 30%
To find,
markup percentage on selling price
Markup is the ratio between the cost of a good or service and its selling price.
Let suppose that cost price percentage = 100%
As we know that,
<h3>cost% + markup% = selling%</h3><h3>100% + 30% = 130%</h3>
So percent markup selling price = 30 / 130 x 100
= 23.0769
Hence, 30% markup on cost price = 23.0769% markup on selling price.
Answer:
For t=3 sec the velocity change from positive to negative
Step-by-step explanation:
we have
This is the equation of a vertical parabola open downward (the leading coefficient is negative)
where
s(t) is the distance in feet
t is the time in seconds
We know that
To find out when the velocity change from positive to negative, we need to determine the turning point of the quadratic equation
The turning point of the quadratic equation is the vertex
so
Convert the quadratic equation into vertex form
Factor -16
Complete the square
Rewrite as perfect squares
The vertex is the point (3,244)
therefore
For t=3 sec the velocity change from positive to negative
146° + (-39 +x)° = 180°
Subtract 146° on both sides.
(-39 +x)° = 180° - 146°
(-39 +x)° = 34°
(x - 39)° = 34°
Add 39° on both sides
x = 34° + 39°
x = 73°
Your final answer is C) 73.
