We use unitary method over here. To find out the number pages he writes in 1 hour we should;
16÷8 = 2.
So Brennan writes 2 pages in 1 hour.
Hence, in 10 hours he writes;
2 × 10 = 20.
∴ in ten hours Brennan writes 20 pages.
Answer:
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Step-by-step explanation:
0 = – 3x2 – 2x + 6
It can still be written as
– 3x2 – 2x + 6 =0
Quadratic formula=
-b+or-√b^2-4ac/2a
Where
a=-3
b=-2
c=6
x= -(-2)+ or-√(-2)^2-4(-3)(6)/2(-3)
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Its 576 if you multiply 48 and 12 you get 576
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.
