the answer is 11.
use BEDMAS, and calculate the equation inside the brackets (answer to that is 44/15)
then divide it by 4/15 and you get 11
Answer: e. (0.35- 0.25)±1.96 √ (0.35)(0.65)/400+ √ (0.35)(0.75)/400
Step-by-step explanation:
Answer:
62.5%
Step-by-step explanation:
im right
1/9
Here's the proper explanation:
Since the vertex is (2,-1), the original equation will look like this: y=a*(x-2)^2-1
When the substitution happens we get to this:
0=a*(5-2)^2-1 then 1=a*(5-2)^2 -> 1=a*9
So, a=1/9! Written in another form:
1/9x^2-4/9x+4/9-1
Hope could help :)
It depends on student brain capability to understand the teacher, atleast 2 times is enough for a Brilliant student and an average student would take atmost 5 while the dull ones it would have to repeated until he or she gets it
