An octagon has 8 sides. Each side is given as 2a + 1
Perimeter = 8(2a + 1)
= 16a + 8
Answer: 16a + 8
Hey there!
<u>-3 and 1 will both be farther to the right on the number line.</u>
On a number line, the farther right you go, the higher the values get.
Positive numbers are to the right of zero, with negative numbers to the left.
Since both -3 and 1 are larger than -7, they will be farther to the right.
Hope this helps!
Answer:29
Step-by-step explanation:
27r=783
divide both sides by 27
27r÷27=783÷27
r=29

Fourth try = 0.0973
Let X be the number of failed attempts at passing the test before the student passes. This
is a negative binomial or geometric variable with x â {0, 1, 2, 3, . . .}, p = P(success) = 0.7
and the number of successes to to observe r = 1. Thus the pmf is nb(x; 1, p) = (1 â’ p)
xp.
The probability P that the student passes on the third try means that there were x = 2
failed attempts or P = nb(2, ; 1, .7) = (.3)2
(.7) = 0.063 . The probability that the student
passes before the third try is that there were two or fewer failed attmpts, so P = P(X ≤
2) = nb(0, ; 1, .7) + nb(1, ; 1, .7) + nb(2, ; 1, .7) = (.3)0
(.7) + (.3)1
(.7) + (.3)2
(.7) = 0.973 .</span>
Answer: 
Step-by-step explanation:
By the geometric mean theorem,
So, by the Pythagorean theorem,
