<h3>
Answer: 0.98976</h3>
===========================================================
Explanation:
60% of the people have been vaccinated, so 40% have not.
The probability of getting five people in a row that aren't vaccinated is (0.40)^5 = 0.01024
Subtract this from 1 to get the probability of at least one vaccinated person in the sample of five.
1-0.01024 = 0.98976
This works because the events "at least one vaccinated" and "none vaccinated" are complementary. One or the other must happen, which means the two probabilities add to 1.
An easy way to solve this equation is to plug in the coordinates.
A. 6(2) + 8 ≠ 1
✅ B. 6(-1) + 8 = 2
C. 6(2) + 8 ≠ 4
D. 6(-2) + 8 ≠ 4
Answer:
A) no real solutions
Step-by-step explanation:
No real solution. in order to x+1 by itself you must square root both sides. that would mean square rooting -5 which creates an imaginary number. so there are no real solutions. Also cause even if x was a negative, when you'd square it, you'll always get a positive.
