Answer:
43.96 is pretty sure
Step-by-step explanation:
C=2πr
c= 2π(7)
using 3.13 as pie
c= 2(3.14)(7)
43.96
Answer: 0.07
Step-by-step explanation: Since it is a binomial experiment , we will use the formula:
n C r 

p = 0.35
q = 1 - 0.35 = 0.65
n is the number of trials = 7
r = 3
substituting into the formula, we have
7 C 3 (

= 35(

=0.0736
to the nearest tenth
= 0.07
You could use the Pythagorean Theorem to find this. Since the two legs will be the same length:
5² + 5² = c²
25 + 25 = c²
50 = c²
√50 = √c²
5√2 = c
so the hypotenuse length is 5√2
What 2 numbers multiply to -35 and add to -2
the bigger factor is negative since they add to a negative number
add factors, bigger one is negative
1-35=-34, nope
5-7=-2, yep
(x+5)(x-7)
