If you would like to solve the inequality 4 * (x + 2)^2 < 0, you can do this using the following steps:

4 * (x + 2)^2 < 0
4 * (x^2 + 4x + 4) < 0     /4
x^2 + 4x + 4 < 0
no solutions

The correct result would be: There are no solutions.

Demarco substitutes a value for x in the equation 2x = 4.
MA_775_DIABLO [31]

Answer:

If both sides are equal

Step-by-step explanation:

If both sides are equal and are the same in both sides of the equation, than it is a solution.

For instance, the solution for 2x = 4, is x = 2 because 2(2) = 4 is 4 = 4.

Diano4ka-milaya [45]

Answer:

0.505 g is <em>more than</em> the advertised amount by 0.005 g.

Step-by-step explanation:

0.5 = 0.500, so 0.505 is <em>more than</em> the advertised amount.

"Too little" or "too much" is a judgment based on some criteria not specified by the problem statement. Usually a supplier will want to ensure the customer receives full measure, so will adjust the capsule-making machine to provide at least the advertised amount. Whether it is "too little" or "too much" depends on your point of view and the dangers or costs of deviating from the advertised amount.

0.505 - 0.500 = 0.005 . . . . the difference between the actual and advertised amounts, in grams.

enyata [817]

Answer: 0.5507

Step-by-step explanation:

Given : The waiting time, in hours, between successive speeders spotted by a radar unit is a continuous random variable X with a cumulative distribution function

F(x)= \begin{cases}0,& x

Since , the waiting time is in hours , then we can write 12 minutes as \dfrac{12}{60} hour i.e.0.2 hour.

Now, the probability of waiting fewer than 12 minutes between successive speeders is given by :-

P(X

Hence, the required probability = 0.5507
