A stock lost 8 1/4 points on Monday and then another 2 3/4 points on Tuesday. On Wednesday, it gained 12 points.
What was the net gain or loss of the stock for these three days?
The net gain of the stock for these three days is 1 points
Net gainMonday = - 8 1/4 pointsTuesday = -2 3/4 pointsWednesday = 12 pointsNet gain / net loss = Monday + Tuesday + Wednesday
= - 8 1/4 + (-2 3/4) + 12

The domain of the inverse of a relation is the same as the range of the original relation. In other words, the y-values of the relation are the x-values of the inverse.
Thus, domain of f(x): x∈R = range of f¯¹(x)

In the binomial probability distribution function, nCx represents the number of ways of obtaining x successes in n trials. True or False?
In the binomial distribution for probability function, [tex]_{n}C_{x}[/tex] represents the number of ways of obtaining x successes in n trials: True
What is binomial distribution?The binomial distribution is a type of probability distribution that expresses the probability that, given a certain set of characteristics or assumptions, a value would take one of two distinct values.
The underlying assumptions of the binomial distribution are that each trial has exactly one possible outcome, that each trial has the same success chance, and that each trial is either independent of or mutually exclusive with every other trial.
As opposed to a continuous distribution, like the normal distribution, the binomial distribution is a frequent discrete distribution used in statistics.

c. determine the particle's speed when it has been moving for 3 minutes. Give your answer in m [tex]S^{-1}[/tex]
(a) The particle's distance from O when it first started to move is 24 m.
(b) The time when the particle first reaches O is 15 mins.
(c) The particle's speed when it has been moving for 3 minutes is 0.2 m/s.
Particle's distance from O when it first started to move
D = 24 + 15 - t²/2
when the time, t = 0
D = 24 m
When the object first reaches OWhen the object reaches O, its final velocity, v = 0
v = dD/dt
v = 15 - t
0 = 15 - t
t = 15 mins
Speed of the particle after 3 minutesv = 15 - t
v = 15 - 3
v = 12 m/min
v = 12 m/min x 1min/60s = 0.2 m/s
Thus, the particle's distance from O when it first started to move is 24 m.

The equation of the given Absolute Value Function is; y = |-2x + 4|
How to interpret Linear Graphs?We can see that the given graph is a Linear graph but since it is V-shaped, we can say that it is a graph of an absolute value function.
Now, from the graph we see that;
At x = 0, y = 4
At x = 1, y = 2
At x = 2, y = 0
At x = 3, y = -2
At x = 4, y = 0
At x = 5, y = 2
We can see that the y-intercept is at y = 4.
Slope between two consecutive points is;
(2 - 4)/(1 - 0) = -2
Equation is; y = -2x + 4
Now, this is an absolute value function and as such we will write it as;

The perimeter of the rectangle based on the factors given is 46.
How to calculate the perimeter?The area of the rectangle is given as (x² + 13x - 90). This will be:
= (x² + 13x - 90)
= x² + 18x - 5x - 90
= x(x + 18) - 5(x + 18)
= (x - 5)(x + 18)
The sides of the rectangle are 5 and 18. The perimeter will be:
= 2(l + w)
= 2(5 + 18)
= 46
The area of the rectangle is given as (x² + 24x - 81.
= (x² + 24x - 81)
= x² + 27x - 3x - 81
= x(x + 27) - 3(x + 27)
= (x - 3)(x + 27)
The sides are 3 and 27. The perimeter will be:
= 2(l + w)
= 2(27 + 3)
= 60
= (x + 1)² + 3(x + 1) + 2
= (x + 1)(x + 1) + 3x + 3 + 2
= x² + x + x + 1 + 3x + 5

[Use the inequality 0.35x + 0.99y + 0.59 ≤ 4]
Yes, because the total will be $3.27
Yes, because the total will be $1.93
No, because the total will be $4.27
No, because the total will be $5.93
Answer:
The answer to your question is A. Yes, because the total will be $3.27
0.35(2)+0.99(2)+0.59≤4.
Then you multiply: .35(2)=.70. .99(2)=1.98.

Which of the following rational functions is graphed below?
Answer:
D
Step-by-step explanation:
As the function approaches a certain x-value, it makes a very sharp turn and doesn't touch the axis as you can see in the graph. It does that because if the x-value is applied to the function, it would make it undefined. In this case, the graph is approaching x = -3 and x = +7 since at those points, the lines for the graph change suddenly. You would look for a function that if x is -3 or 7, it makes the y-value undefined.
Another way to easily do this would be to substitute values that are in front of the value that the graph is avoiding like 6 or 8 for 7 and -2 and -4 for -3. You can see if the y-values that would output from substituting those numbers are correct.
You should rotate tires on a car at regular intervals. In how many ways can four tires be arranged on a car?
The tires can be arranged in 24 ways. Computed using permutation.
The permutation is a way of selecting a smaller set from a larger set when the order of selection is not of concern.
For selecting r number of items, from n number of items, with the order of selection not being a concern, we can calculate the number of ways using permutation:
nPr = n!/(n - r)!.
In the question, we are asked the number of ways in which the four tires can be arranged on a car.
As we need to select 4 tires, from 4 tires, with any order, we will use permutation.
Thus, the number of ways can be calculated as 4P4, which can be calculated using the formula, nPr = n!/(n - r)!.
Thus, 4P4 = 4!/(4 - 4)! = 4!/0! = 24/1 = 24.
Thus, the tires can be arranged in 24 ways. Computed using permutation.

Koos spent 3/7 of his monthly pocket money during the first week. The following week he spends two- thirds of what he had spent the previous week. The fraction of the pocket money that is still left is.
Answer: 2/7
Step-by-step explanation:
The total amount of pocket money he has is 7/7.
He spent 3/7 of his pocket money during the first week.
He then spends 2/3 of what he spent the previous week, 2/3 * 3/7 which is 2/7.
What he has left is 7/7 - 3/7 - 2/7 = 2/7.
