Answer:
x=3+i or x=3-i
Step-by-step explanation:
x²-6x+10=0
(x²-6x+9) + 1 = 0
(x-3)² + 1 = 0
(x-3)² = -1
x-3 = ± √-1 = ± i
x = 3 + i or x = 3 - i
Answer:
The greatest number of piñatas you can make with the gifts is:
Step-by-step explanation:
To identify the greatest number of piñatas, you must think in a number that can divide another and obtain a whole number with this:
Bigger the number, greater the number of piñatas, in this case, you can see the numbers given can be divided into four numbers obtaining a whole number: 1, 2, 3, and 6. Remember that the best number is the greatest, in this case, number six. Now you proceed to divide the <u>numbers into 6</u>:
Taking into account the values obtained, you can see that each piñata would have: <u>3 bottles of nail polish, 4 pairs of earrings, and 7 lollipops</u>.

My answer:
C and Y are not independent events because P(C∣Y) ≠ P(C).
Probability of C = 110/300 = 0.37
Probability of Y = 75/300 = 0.25
Probability of (C|Y) = 0.37 * 0.25 = 0.0925
As you can see, </span><span>P(C∣Y) is 0.0925 which is not equal to P(C) = 0.37. Thus, C and Y are not independent events. </span><span>

Whole numbers between those two would be 11, 12, and 13.
