For number 1, it says based on the first two clues, so you would still include the even numbers ranging from 70-81. Then for number 2 we would use clue C because it gives us the most information about our number.
R^2+2r-33=0 move constant to other side by adding 33 to both sides
r^2+2r=33 halve the linear coefficient, square it and add to both sides, in this case it is just one
r^2+2r+1=34 now the left side is a perfect square...
(r+1)^2=34 take the square root of both sides...
r+1=34^(1/2) subtract 1 from both sides
r=-1+34^(1/2) and -1-34^(1/2)
The < and > signs mean lesser and greater than. = means equal(s). The signs will always look like they are eating the bigger value. For example:
12<29
Twelve is lesser than twenty-nine, or
29>12
Twenty-nine is greater than twelve.
An equation uses an equal sign
12+8=20
When you're using all of them, it can look like this:
1<n<29
This is read as "one is lesser than n which is lesser than 29". These can be used to determine the lengths of the sides of a triangle. In this case, n must be between 1 and 29 for it to be the side of a triangle.
Answer:
1/46656 I believe. probability isn't really my strong suit tho.
Step-by-step explanation:
1/6 chance for rolling a one × 1/6 chance of rolling a two and so on.
so you get
1/6 × 1/6 × 1/6 × 1/6 × 1/6 × 1/6 = 1/46656
