Answer:
y=2x-3
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=2(x-(-3))
y+9=2(x+3)
y=2x+6-9
y=2x-3
1,200/1,200
Hope this helps!
Answer:

Step-by-step explanation:
For a coin, the probability of head showing in a single toss is
.

Its complement, the probability of not head is

This is a binomial distribution. In
tosses, the probability of having all heads (i.e.
heads) is

Let's call this value
.
For
coins, we determine the probability of at least 1 coin showing all heads by first finding its complement i.e. the probability of no coin showing all heads. This is also a binomial distribution.
