Step-by-step explanation:
Given
The function is 
for
, we will check the values of
and 
Take 3 and 4

Similarly,

Thus, 
Also,
is 1 i.e. a constant value. So, the function is increasing linearly for the given interval.
Answer:
$94.81
Step-by-step explanation:
the selling price (before discount 20%) =
$98.60 ÷ (100-20)%
= $98.60 ÷ 0.8 = $123.25
the store paid for the clarinet =
$123.25 ÷ (100+30)%
= $123.25 ÷ 1.3 = $ 94.81
First, you have to set a system of equations to determine the number of fiction and of nonfiction books.Call f the number of fiction books and n the number of nonfiction books. Then 400 = f + n. And f = n + 40 => n = f - 40 => 400 = f + f - 40 => 400 - 40 = 2f => f = 360 / 2 = 180. Now to find the probability of picking two fiction books, take into account the the Audrey will pick from 180 fiction books out of 400, and Ryan will pick from 179 fiction books out of 399, so the probability will be<span> (180/ 400) * (179/399) = 0.20 (rounded to two decimals). Answer: 0.20</span>
Answer:
: 1
Step-by-step explanation:
they are both divisible by 4 so you divide. You will get 4:3. Since you wanted n:1 , you have to divide both sides by 3. the answer is
: 1
