Given
This is a one-tailed test.
Since the p-value of the sample statistic (0.00383) is less that the significant level (0.025), we reject the null hypothesis.
V = 1/3*r^2*pi*h
6 = 1/3*2^2*pi*h
H = 6*3/(4*pi) = 1.4
3x-9-5x = -7
combine like terms -9-2x = -7
add 9 to both sides
-2x = 2
divide both sides by -2
x - 2/-2 = -1
x = -1
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
This is a thought problem
