****ASAP***** can someone pls help me with this? and can you describe it please?
1 answer:
Add 165 to 245. That is a total of 410kWh.
245kWh is more than 50% of 410kWh.
So, according to the plan, you will pay NightTimer rate for kWh at night and DayTimer rate during the day.
The work done:
The raw, accurate, answer is that the value to pay is $22.08085.
In real terms, it is closer to your $22.08 option. That is the one I'd take.

Answer:
d. −7/32
Step-by-step explanation:
The expression that we have to evaluate in this problem is:
We have to evaluate this expression for:
x = -2
y = 4
We start by rewriting the expression by rewriting it using the following:
So the expression can be rewritten as
Now we observe that:
Therefore, by substituting x = -2 and y = 4 into the expression, we find:
A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).
<h3>What is a quadratic equation?</h3>A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.
It is written in the form of ax²+bx+c.
The factored form of the quadratic equation can be done in the following manner,
Thus, the factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

Answer:
Helene is right
Step-by-step explanation:
Mathematically, the expected values is defined as the sum of all the possible outcomes that an event can have times the probality of the respective outcome:
x = ∑ p *i,
where x is the expected value, i represents every outcome that can occur, and p is the probability of said outcome.
Now, for the case of a dice, the expected value would be:
x = 1 * + 2 *
+ 3 *
+ 4 *
+ 5*
+ 6 *
,
as every outcome has the same chance of happenning. Solving we get that:
x= *(1 +2 +3 +4+5+6) =
* 21 = 3.5
