x = 1/2m
Step-by-step explanation:
Answer: 37°F
let me know if this is wrong
Step-by-step explanation:
30-15=15
15+22=37
1. a b c
2. a b c
3. a b c
4. a b c
5. a b c
then she eliminated 1 choice in 1 and 2, say as follows
1. b c
2. a b
3. a b c
4. a b c
5. a b c
Probability of answering correctly the first 2, and at least 2 or the remaining 3 is
P(answering 1,2 and exactly 2 of 3.4.or 5.)+P(answering 1,2 and also 3,4,5 )
P(answering 1,2 and exactly 2 of 3.4.or 5.)=
P(1,2,3,4 correct, 5 wrong)+P(1,2,3,5 correct, 4 wrong)+P(1,2,4,5 correct, 3 wrong)
also P(1,2,3,4 c, 5w)=P(1,2,3,5 c 4w)=P(1,2,4,5 c 3w )
so
P(answering 1,2 and exactly 2 of 3.4.or 5.)=3*P(1,2,3,4)=3*1/2*1/2*1/3*1/3*2/3=1/4*2/9=2/36=1/18
note: P(1 correct)=1/2
P(2 correct)=1/2
P(3 correct)=1/3
P(4 correct)=1/3
P(5 wrong) = 2/3
P(answering 1,2 and also 3,4,5 )=1/2*1/2*1/3*1/3*1/3=1/108
Ans: P= 1/18+1/108=(6+1)/108=7/108
You just do -52 divided by 4 and get -13 as your answer.
m = -14
Answer:
Part 1) "a" value is 
Part 2) The vertex is the point 
Part 3) The equation of the axis of symmetry is 
Part 4) The vertex is a minimum
Part 5) The quadratic equation in standard form is 
Step-by-step explanation:
we know that
The equation of a vertical parabola into vertex form is equal to

where
(h,k) is the vertex of the parabola
if a > 0 then the parabola open upward (vertex is a minimum)
if a < 0 then the parabola open downward (vertex is a maximum)
The equation of the axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex
so

In this problem we have
-----> this is the equation in vertex form of a vertical parabola
The value of 
so
a>0 then the parabola open upward (vertex is a minimum)
The vertex is the point 
so

The equation of the axis of symmetry is 
The equation of a vertical parabola in standard form is equal to

Convert vertex form in standard form
