Answer:
x = -5
Step-by-step explanation:
x = -20/4 = -5
He would need to sell 28 because
12.50*28=350 and 350+50=400
Answer:
P = number of adults who have shopped at least once on the internet / number sampled adults
Step-by-step explanation:
Step 1
Let X be the number sampled adults
Let Y be the number of adults who have shopped at least once on the internet.
Let P be the probability that a randomly selected adult has shopped on the Internet.
Step 2
P = number of adults who have shopped at least once on the internet / number sampled adults
P = Y/X
An example:
If X is 1000 adults and Y is 200 adults therefore P = 200/1000 = 0.2
One can therefore infer that approximately 0.2 of the population surfs the internet at least once in a week.
Slope is rise over run or
(y1-y2)/(x1-x2)
(x,y)
x1=17
x2=-11
y1=-6
y2=7
slope=(-6-7)/(17-(-11))=(-13)/(17+11)=(-13)/(28)=
the slope is -13/28
