David rolls a number cube fifty times. The number 4 comes up twelve times. The number 3 comes up eight times. What is the experi
Maurinko [17]

Answer:

40%.

Step-by-step explanation:

Prob( Rolling a 4) = 12/50

Prob( Rolling a 3) = 8/50

When the combined probabilities contain  an 'OR' we Add the probability values:

Probability of a 3 or a 4  

= 12/50 + 8/50

= 20/50

= 2/5

= 40%.

I have to transfer this graph into a vertex form equation, but I'm not sure how to.​
tino4ka555 [31]

Answer: y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2

Step-by-step explanation:

vertex form is y=a(x-h)^2 + k

here we can see the vertex is (3,0) which is (x,y). Or (h,k) in this case.

so to plug that into vertex form, we now have y=a(x-3)^2 + 0. or just y=a(x-3)^2.

now we need to find "a" which is the leading coefficient. to do that we can plug in the (6,-6) for the x and y parts of the above equation. so we'd have

-6=a(6-3)^2. which goes to -6=a(2)^2 which is -6=4a. divide each side by 4 to get a = -2/3. plug this in for a

the final equation would be y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2

Explain how to use proportional reasoning to find 35% of 600
Sauron [17]
\frac{35}{100} = \frac{x}{600}

This is the equation we would use for this problem.

Now when we cross multiply, we get:
 35(600)=100x

Simplify:
21000=100x

Divide each side by 100 to get x b itself:
210=x

So, as you can see, 210 is 35% of 600
