For a lower tail test, the p-value is the probability of obtaining a value for the test statistic is at least as small as that provided by the sample.
Probability is the probability that something will happen. Whenever the outcome of an event is uncertain, we can speak of the probability, or likelihood, of a particular outcome. Probabilistic analysis of events is called statistics.
The lower-tailed test is a one-tailed test in which the critical region of the distribution is one-sided (leftmost) and tests whether a sample is less than a specified value.

cube root of 0.000729
Answer: 0.09
Step-by-step explanation:
Use the figure below for questions 11 – 13.
11. ∠1 = ___°
12. ∠3 = ___°
13. ∠5 = ___°
The value of ∠1 is 140°, ∠3 is 65° and ∠5 is 115° after using the values of angles given in the figure.
According to the question,
We have a figure where some of the angles are given and we have to find angles which are numbered from 1 to 5.
In solving this question, we need to keep in mind two things. First is that the angle made on a straight line is always 180° (this will be referred to as the former part). Second is that the exterior angle of a triangle is equal to the sum of the opposite interior angles of that triangle (it will be referred to as the latter part).
So, to find ∠1, we will use the latter part.
∠1 = 80°+60°
∠1 = 140°
Now, in order to find ∠2 we will use the former part (angle made on a straight line).
∠1 + ∠2 = 180°
140° + ∠2 = 180°
∠2 = (180-140)°
∠2 = 40°
Now, to find ∠3, we will use the latter part.
∠2 + ∠3 = 105° (105° is an exterior angle)
40° + ∠3 = 105°
∠3 = (105-40)°
∠3 = 65°
Now, to find ∠4, we will use the former part.
∠4 + 105° = 180°
∠4 = (180-105)°
∠4 = 75°
Now, after looking at the figure, it can be clearly seen that ∠5 is an exterior angle.
So, we have:
∠5 = ∠4 + 40°
∠5 = 75° + 40°
∠5 = 115°
Hence, the value of ∠1 is 140°, ∠3 is 65° and ∠5 is 115°.

Given that w =(x + y)/z

find the lower and upper bounds of w.
The lower and upper bounds of w is 3 and 4.16
What is Upper bound and Lower bound?
An element of K that is bigger than or equal to every element of S is referred to as an upper bound or majorant of S in mathematics, specifically in order theory. In contrast, a lower bound or minorant of S is defined as an element of K that is smaller than or equal to every element of S. A set that has an upper (or lower) bound is said to be majorized[1] (or minorized, respectively) from above (or below) by that constraint.
Given that,
w =(x + y)/z
x = 2.5 ± 0.5,
y = 1.5 ± 0.5
and, z = 1.1 ± 0.1
Substituting the values in the equation to find upper bound
x = 3.0
y = 2.0
z = 1.2
Then,
w = (3 + 2)/1.2
w = 5/1.2
w = 4.16
Substituting the values in the equation to find lower bound
x = 2.0
y = 1.0
z = 1.0
Then,
w = (2 + 1)/1
w = 3/1
w = 3

If we solve 4x-3y=3, -8x +6y=-6 by substitution or elimination, we will have x=3/4 and y=0
We have the following simultaneous equations:

We solve using substitution:
Make x the subject of formula in equation(i):

The quadratic function only has a maximum at y = 2, and:
Domain: All real numbers.Range: y ≤ 2Increases in: (-∞, 2)Decreases in: (2, ∞)How to find the minimum or maximum of the given function?Here we have a quadratic function:
y = -x^2 - 4x - 2
Because the leading coefficient is negative, we know that the parabola opens downwards, then we only have one maximum which is at the vertex.
The x-value of the vertex is at:
x = -(-4)/(2*-1) = 4/-2 = -2
Evaluating in that x-value we will get the maximum:
y = -(-2)^2 - 4*-2 - 2 = -4 + 8 - 2 = 2
The maximum is y = 2.

The domain is the set of all real numbers like in all quadratics.

The maturity value of a loan is the total amount you must repay, including the principal and any interest you incur.
The interest is calculated by:
I = Prt
Where P is the amount of the loan, r is the interest rate and t is the time of the loan.
We are given:
P = $3345
r = 10.5%
t = 87 days
Convert the interest rate to daily by dividing by 365 (assuming a calendar 365-day year):
[tex]r=\frac{10.5}{100\cdot365}=0.00028767[/tex]Calculate the interest (we keep all the decimals in the calculator):
I = $3345 x 0.00028767 x 87
I = $83.72
The maturity value (final value) of the loan is:
FV = P + I = $3345 + $83.72
