Narrowing it down it's either a or c because the other 2 choices open downward (negative a).
Graphing the 2 parabolas choice c is narrower.
c
Y=mx + b
10x.5y.10=30
10x.5y=30-10
10x.5y=20
5y= -10x + 20
5/5 = -10/5(x) + 20/5
Y= -2x +4
Know as a fractional equation, so the answer is B.
The friend's probability of beating the next level on her first attempt are 22.5 percent.
Describe probability.
To forecast how likely occurrences are to occur, probability has been introduced in mathematics. This is the fundamental theory of probability, which is also applied to the probability distribution, and from which you will discover the likelihood of results for a random experiment.
This idea is used to discuss the probability or likelihood of an event happening.
The frequency of the number 8 is seven.
The frequency of the number 9 is 11.
The full list of frequencies is provided as
10 + 9 + 6+ 7 + 8 + 12 + 4 + 6 + 7 + 11 = 80
7 + 11 = 18
18/80 is the probability.
= 0.225 x 100
22.5 percent
