When coin a is flipped, it lands on heads with probability 0.4; when coin b is flipped, it lands on heads with probability 0.7.

one of these coins is randomly chosen and flipped 10 times. given that the first of these 101 flips lands on heads, what is the conditional probability that exactly 7 of the 10 flips land on heads?

Answer:

The side opposite angle C

Step-by-step explanation:

The angles of a triangle must add up to equal 180°. So 180=59+57+x

180=116+x

x=64°

In a triangle the smallest side is always opposite the smallest angle

The inverse would make the inputs the outputs (switching the x's and y's) because plugging in 4 into the inverse would somehow output 4 and 5, the inverse could not exist. plug in the inverse points to see that the vertical line test would fail.

2,10,18,26 find the 61st term
saw5 [17]

Answer:

482

Step-by-step explanation:

We can see that the numbers shown resemble an arithmetic sequence because they have a common difference. The formula for the nth term of an arithmetic sequence is:

a_{n} =a_{1} +(n-1)d

Where a_{1} is the first term, a_{n} is the nth term, and d is the common difference. To find the 61st term, all we need is the first term and the common difference. By looking at what given, we can say the first term is 2. Now, to find the common difference, we find the difference of a term from the term before it. In this case we can do 10-2, which is 8 , or the common difference. Since we have everything we need, it can be plugged into the equation:

a_{61} =2 + (61 - 1)*8\\a_{61} = 2 + 60*8\\a_{61} = 2 + 480\\a_{61} = 482

So, the 61st term is 482.
