Answer:
I used to have this question it is -9/20 because -10/20 is -0.5
Step-by-step explanation:
Answer:Answer C) 7
Step-by-step explanation:
M= -14-20+32
-34 + 32
M=-2
N= 19-32+22
N = 19-10
N = 9
M + N = -2+9
M+N = 7
Answer c
The x value of the vertex in
ax^2+bx+c is -b/2a
y value is just sub for x
3x^2-6x+5
x value of vertex is -(-6)/(2*3)=6/6=1
sub back
y=3(1)^2-6(1)+5
y=3(1)-6+5
y=3-1
y=2
vertex is (1,2)
Answer:
y= -2
Step-by-step explanation:
Answer:
33 1/3%
Step-by-step explanation:
When you roll a die, the possible outcomes are 1,2,3,4,5,6
getting a number less than 5: 1,2,3,4
P( getting a number less than 5)
= number of outcomes that meet conditions / total outcomes
=4/6
= 2/3
Then we flip a coin heads or tails
We want heads
P (heads) = number of outcomes that meet conditions / total outcomes
= 1/2
Since the event outcomes do not depend on each other
P( getting a number less than 5) *P (heads) = 2/3 * 1/2 = 1/3
as a percent
= 33 1/3%
