Answer:
Step-by-step explanation:
We are given the following in the question:
Quantity, q
Selling price in dollars per yard, p
Total revenue earned =
f(20)=13000
This means that 13000 yards of fabric is sold when the selling price is 20 dollars per yard.
f′(20)=−550
This means that increasing the selling price by 1 dollar per yards there is a decrease in fabric sales by 550.
We have to find R'(20)
Differentiating the above expression, we have,
Putting the values, we get,
Answer:
35%
Step-by-step explanation:
Data provided in the question:
P(Master card) = 27% = 0.27
P(American express card) = 19% = 0.19
P( Visa card ) = 22% = 0.22
P( Master and American express card ) = 9% = 0.09
P( Visa and master card ) = 14% = 0.14
P( American express and visa card ) = 6% = 0.06
Now,
The probability of selecting a family that has either a Visa card or an American Express card
= P( Visa card ) + P( American express card ) - P( Visa and American express card )
= 0.22 + 0.19 - 0.06
= 0.35
or
= 0.35 × 100% = 35%
Area: 153.9m
formula: 3.14(r^2)
7^2= 49
3.14•49=153.86
153.86 rounded is 153.9
Answer:
3
Step-by-step explanation:
This is written in the form
y= mx+b
where m is the slope and b is the y intercept
3 is the slope and -4 is the y intercept
