Answer:
a. 15 on top 8 on bottom
b. 2 on top -3 on bottom
c. 4 and 2
d. 4 on top 8.5 on bottom
e. -3 and -4
Step-by-step explanation:
multiply the two numbers on the sides to get the top answer and add them together to get the bottom answer.
Answer:
20
Step-by-step explanation:
ones= 1
tens= 10
Hundreds= 100
The difference between ones and tens is the 0. ones=1. tens=10
<u>2</u>4
The 2 is in the beginning so its the 10's place. The 4 is the second number so its in the ones place
Don't repost. be patient and we will answer
so
remember some stuff
to find the axis of symmetry of y=ax^2+bx+c
the axis of symmetry is x=-b/(2a)
that is also the x value of the vertex
to get the y value of the vertex, sub the x value of the vertex into the function
and if a is positive, then the parabola opens up and the vertex is a minimum
if a is negative, parabola opens down and vertex is max
so
y=3x^2-6x+4
3 is positive so vertex is a minimum
axis of symmetry is -(-6)/(2*3)=6/6=1
x=1 is axis of symmetry and x value of vertex
sub to find y
y=3(1)^2-6(1)+4
y=3(1)-6+4
y=3-2
y=1
axis of symmetry is x=1
vertex is (1,1)
it is a minimum
the parabola opens up
Answer:
Step-by-step explanation:
So, first lets the probability of just finding a yellow marble. There are 9+5+2+4 marbles in total, and that is 19 marbles.
5 out of those 20 are yellow, so the probabilty is 5/20 which is 1/4 or 20%
Then, lets do just finding the probability of a color that isn't blue.
Out of 20 marbles, 11 are color not blue, and 9 are.
So that probability is 11/20
Now, I think we need to do 11/20-5/20 so 6/20=3/10
Im so sorry, I might be wrong. I found both probabilities but I dont know if my final step is right.
