Number of unmarked wolves: 928 - 232 = 696
probability of next wolf being unmarked = 696 / 928 = 0.75
0.75 x 100 = 75%
Answer: 75%
Answer:
x = 2, x = -8
Step-by-step explanation:
Since the equation equals 0, you know either (x-2) or (x+8) has to equal 0.
This means x = 2, and x = -8
Hope this helps!
The answer is 12
All possible units are 13, 15, 19, 31, 35, 39, 51, 53, 59, 91, 93, 95
A.
the radicand is b²-4ac
if it is in form ax²+bx+c
when it is
greater than 0, then 2 real roots
equal to 0, then 1 real root
less than 0, then no real roots
so
a=4
b=-12
c=10
b²-4ac=(-12)²-4(4)(10)=144-160<0
so 0 real roots
B.
using quadratic formula because it is easier
for
ax²+bx+c=0
so
for 2x²-13x+21
a=2
b=-13
c=21
x=(13+1)/4 or (13-1)/4
x=14/4 or 12/4
x=7/2 or 3
Z=-(b+17/9+4) if that help you
