Suppose that you flip a coin 13 times. What is the probability that you achieve at least 5 tails?
wariber [46]
Heads, or tails. It's 1/2 a chance, because either way you will either land heads or tails. It would be a probability of 1-(1/2)^5. Can you solve that?

The roof of a barn rises vertically 2.5 meters through the horizontal distance of 10 meters. What is the pitch (slope) of the ro
Lesechka [4]

Answer:

The pitch (slope) of the roof is 0.25  or 25\%

Step-by-step explanation:

we know that

The formula to calculate the slope  is equal to

m=\frac{y2-y1}{x2-x1}

where

In this problem we have

{y2-y1}=2.5\ m  -----> is the vertical distance (rises)

{x2-x1}=10\ m   -----> is the horizontal distance (run)

substitute the values

m=\frac{2.5}{10}=0.25

convert to percentage form

0.25*100=25\%

the formula to find the diagonal would be

a^2+b^2=c^2

3^2+4^2= 9+16=25

the square root of 25 is 5

5^2=25
