Answer:
2 imaginary roots
Step-by-step explanation:
The discriminate is the portion of the quadratic equation under the square root
D = b^2 - 4ac
D = 8^2 - 4(2)(16)
D = 64 - 128
D = -64
Since the discriminate is negative the square root will be imaginary
and there will be 2 of them
2 imaginary roots
The answer is: " 6.4 blocks " .
________________________________________________________
3.2 blocks (one way), PLUS: 3.2 blocks the other way:
3.2 + 3.2 = 6.4 blocks .
or: (3.2) * 2 = 6.4 blocks .

Hey, there’s no circle for me to look at unfortunately!
Answer:
D
Step-by-step explanation:
Lower bound of the population mean is 0.328
Upper bound of the population mean is 0.486
Confidence level is 99%
Therefore, the correct interpolation of the confidence interval is that we are 99% confident that the true value of the population mean is between 0.328 and 0.486
Answer:
40, 41, 42
Step-by-step explanation:
x +x+1+x+2=123
3x+3=123
3x=123-3
3x=120
x=120:3
x=40(the first number
40+1=41 (the second number
40+2=42 (the third number
