Answer:
D=[0, 8 214.29]
R=[0, 230 000]
Step-by-step explanation:
In order to find the domain, we must think of the least price you can give to the product you are selling. The price cannot be less than zero, since that would mean that you are giving money to the consumer for taking the product away, so zero is the smallest value p can get.
The greatest value the price can get is the one such that the quantity demanded is zero. So we need to determine that price by setting the equation equal to zero and solving for p.
230,000-28p=0
so we get
-28p=-230,000

so
p=$8,214.29
so the restricted domain for this function would be:

or in interval notation:
D=[0, 8 214.29]
In order to find the range, we just need to determine what's the least and greatest value the function can get. Since this is a linear function, we can find them by just substituting each of the extreme values of the domain in the function, so we get:
q=230,000-28(0)=230,000
q=230,000-28(8214.29)=0
so the range would be:

or in interval notation:
R=[0, 230 000]
Answer:
50(x) and 10+35(x)
Step-by-step explanation:
Because ypu are multiplying 50 by however many hours and then you are adding 10 to 35 foreveryhour
Answer:
0.4 or 40%
Step-by-step explanation:
The total number of trials in this case is 200, since there were 200 single-digit numbers generated.
Of those 200, we know that 95 of them were odd. Of the 95 odd numbers, seven was listed 15 times; this leaves us
95-15 = 80 odd numbers that were not the number 7.
This is 80 numbers out of a possible 200; this is 80/200, which simplifies to 40/100 = 0.4, which is the same as 40%.
Answer:
The independent variable in this experiment was the attention students gets from the teacher
Step-by-step explanation:
An independent variables are variables in maths, statistics and experimental sciences that stands alone and isn't affected by the other variables you are trying to measure.
