Mathematics
1 answer:
Arada [10]2 years ago
5 0

Answer:

if you toss a dice 30 times, you will roll a two 5 times.

Step-by-step explanation:

If you toss a dice once, the probability of rolling a 2 is 1/6, like you said.

So if you multiply your chances of rolling a 2 by 30, you get;

30.1/6 = 30/6 = 5

-y-x=0<br> Write in y=Mx+b
Ymorist [56]

Answer:

y = (-1)x

Step-by-step explanation:

What you are to do here is to "rewrite -y - x = 0 in the slope-intercept form y = mx + b."

Start by solving -y - x = 0 for y:  -y = x or y = -x.

Rewrite this by inserting the coefficient 1 and representing b by 0:

y = (-1)x + 0

which is equivalent to y = (-1)x
