Answer:
the last one bottom right
Step-by-step explanation:
well, did it in my head, but the idea is to calculate it out
(x-8)*(x-8)=50
is just
x²-16x+64=50
to get the 64 down to just 5, we need to subtract 59, on both sides, leaving us with -9 on the righthand side
Answer:
The correct answer is - 0.0529 or 5.29%
Step-by-step explanation:
Given:
The people own dogs = 23%
total population = infinite
Solution:
if you choose a random person, the probability that they own a dog
= 23% or 0.23.
If you pick two people at random then the probability would be:
P(Both the people own dogs) = P(first person own dogs)*P(second person own dogs)
So the probability is as calculated:
P(Both the people own dogs)
= 0.23*0.23
= 0.0529 or 5.29%
I can’t see it , it’s to blurry dude

Answer:
3 ; 4/3
Step-by-step explanation:
x + 4(1/x) = 13/3
x + 4/x = 13/3
x^2 -13/3x + 4 = 0
3x^2 - 13x + 12 = 0
Δ = 169 - 144 = 25
x1 = (13 + 5)/6 = 3
x2 = (13-5)/6 = 4/3
