Take derivitive to find slope

at x=2




so the slope of f(x) at the point (2,24) is 20
use point slope form
the equation of a line that passes through the point

and has a slope of m is

we are given that the slope is 20 and the point is (2,24)
the equation is

simplify into different form yourself if needed
Answer:
Todd's Z-score is - 0.27
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<u><em>Step(i)</em></u>:-
Given data A test is normally distributed with a mean of 70 and a standard deviation of 10.
<em>Mean of the population 'μ' = 70 </em>
<em>Standard deviation of the Population ' σ ' = 10</em>
<em>let 'x' be the random variable in normally distributed</em>
<u><em>Step(ii)</em></u>:-
<em>Given raw score 'x' = 55</em>
Todd's Z-score


Z = -0.27
<u><em>Final answer</em></u>:-
<em>Todd's Z-score is - 0.27 </em>
Answer:
The number of tickets must be sold is 2500
Step-by-step explanation:
The charge for each ticket = $ 5
The concessions amount = $ 1400
The amount paid to players = $ 2000
The amount paid to workers = $ 1600
The cost of each bag given to each fan = $ 3 per bag
Let The number of tickets sold = x
Now, number of ticket sold = number of fans = x
So, According to question
( charge per ticket × number of fans - cost of each bag × number of fan - concession amount ) = amount paid to players + amount paid to workers
Or, $5 x - $3 x - $1400 = $2000 + $1600
Or, $2 x = $3600 + $1400
Or, $2 x = $5000
∴ x =
= 2500
Hence Answer
A. 7 hours ago the temperature was 7 * 1,5 = 10,5 degrees more, so if now it's 0, then it was 10,5 degrees 7 hours ago.
b. in six hours it will be 6 * 1,5 = 9 degrees less, so if it's 0 now, then it will be -9 degrees in 6 hours.
c. the temperature was reading 6 degrees 4 hours ago because:
x * 1.5 = 6 / ÷1.5 (both sides)
x = 4
d. -8 is expected to be in 5 hours and 15 minutes because:
x * 1.5 = 8 / ÷1.5 (both sides)
x = 5 1/3
