The 90th percentile refers to the value above 90 percent of the data. This is illustrated in the figure.
Using a z-table(also attached) or a technology, we can solve that
z=1.28.
Answer:
I believe your answer is C 94.79
If this answer is wrong please let me know my apologies
Step-by-step explanation:
If my math is correct
44.50+44.50=89
89
Now, find the tax value by multiplying tax rate by the before tax price:
tax = 85 × 0.065
tax = 5.53 (tax value rounded to 2 decimals)
Add tax to the before tax price to get the final price:
The final price including tax = 85 + 5.53 = 90.53
90.53 plus the shipping 3.89=94.79
Answer:
1)The rocket hit the ground at
2)The maximum height of the rocket = 12.468 feet
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given equation
y = -2 x² + 5 x + 7 ...(i)
Differentiating equation (i) with respective to 'x' , we get
Equating zero
⇒ -4 x +5 =0
⇒ -4 x = -5
⇒
<em> The rocket hit the ground at </em><em></em>
<u><em>Step(ii):</em></u>-
...(ii)
Again differentiating equation (ii) with respective to 'x' , we get
The maximum height at x =
y = -2 x² + 5 x + 7
<em>The maximum height of the rocket = 12.468 feet</em>
