Answer:

p(not 5) = 5/6

Step-by-step explanation:

The probability that we roll a 5 is 1/6. So, the probability we don't roll a five is simple 1 minus that:

$1-\frac{1}{6} = \frac{5}{6}$

And that's your answer.

Answer:

x = 0

Step-by-step explanation:

i) x - 11 + 1 < 15

x - 10 < 15

x < 10 + 15

x < 25

ii) x - 11 + 1 > 15

x - 10 > 15

x > 25

Therefore to compare (i) and (ii)

25 < x < 25

In any case, x = 0

a paper airplane can be made out of two different pieces of paper: a circular piece 10 inches wide and a square piece 11 inches

madreJ [45]

Compare the areas of the 2 different pieces of paper.

For the circle, the area is A=pi * r^2, which works out to A = pi(5 inches)^2.

For the square, the area is A = s^2, where is the side length, which here is 11 inches.

Finish these calculations, and then compare your two areas. Which is the larger?
