Answer:
in the set of answers: D (no solution )
Step-by-step explanation:
from the possible answers , there is no correct value of x ( A is wrong, B, and C aswell)
the value for x in this equation is equal to 14, hence there is no solution given in the answers
Answer:
Option I and II
Step-by-step explanation:
I. Assuming this represents a random sample from the population, the sample mean is an unbiased estimator of the population mean.
II. Because they're robust, t procedures are justified in this case.
The t procedures are utilized because they are used as a hypothesis testing tool, which allows for testing of an hypothesis applicable to a population where in this case we are testing the null hypothesis about the population mean.
Answer:
Step-by-step explanation:
This can only be written one way.
Let the number = x
x^2 - 10
is how the statement translates.
x^2 = x*x
the 2 means that you need two xs.
The ^ means that you multiply the two xs.
seven less than the quotient of nineteen and a number.
Answer:
125a^3 + 300a^2b + 240ab^2 + 64b^3
Step-by-step explanation:
The volume of a cube is the cube of the side length.
V = s^3
Here, the side length of the cube is 5a + 4b, so we cube 5a + 4b.
V = (5a + 4b)^3
V = (5a + 4b)(5a + 4b)(5a + 4b)
V = (25a^2 + 20ab + 20ab + 16b^2)(5a + 4b)
V = (25a^2 + 40ab + 16b^2)(5a + 4b)
V = 125a^3 + 100a^2b + 200a^2b + 160ab^2 + 80ab^2 + 64b^3
V = 125a^3 + 300a^2b + 240ab^2 + 64b^3
