For a lower tail test, the p-value is the probability of obtaining a value for the test statistic at least as small as that provided by the sample
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
The likelihood that a population parameter will be less than a given value when the null hypothesis is true is expressed as the p-value, also known as a probability value or a measure of significance, for a particular statistical model.

Find the equation of a line in slope-intercept form that is parallel to the line y = -2x + 3 and passes through the point (8, -4).
The equation y = -2x +12 in slope - intercept form.
Find the slope of the line that is parallel to y = -2x +3
Slope (m) = -2
Substitute and calculate ;
m = -2, x = 8 ,y = -4 into y = mx + b
-4 = -2 x 8 + b
Calculate the product :
-4 = -16 + b
Calculate the sum or difference:
-b = -12
b = 12
Again, Substitute m = -2 , b = 12 into y = mx +b :
y = -2x + 12
Rewrite the equation y = -2x + 12 in slope - intercept form:
y = -2x + 12

b)
What is the upper bound of the length of the line?
a) The lower bound of the length of the line is 12.12
b) The upper bound of the length of the line is 12.25
What is a lower bound?
The least value that would round up to the predicted value is the lower bound. The smallest value that would round up to the following anticipated value is the upper bound.
What is an upper bound?
A value that is greater than or equal to every element of a set of data.
What is the difference between the lower and upper bound?
An element of K that is greater than or equal to each element of S is known in mathematics as an upper bound or majorant of the subset S of some preordered set (K, ), especially in order theory. In addition, each element of K that is less than or equal to each element of S is characterized as a lower bound or minorant of S.
Here,
We have to find the lower bound and upper bound of 12.2
We get a lower bound = 12.12

a quantity with an initial value of 5900 decays exponentially at a rate of 0.85% every 7 years. what is the value of the quantity after 99 months, to the nearest hundredth?
The value of the quantity after 99 months is 5228.58.
Given that, an initial value = 5900, rate of decay = 0.85% and time period = 7 years.
What is the exponential decay?The quantity decreases slowly after which the rate of change and the rate of growth decreases over a period of time rapidly. This decrease in growth is calculated by using the exponential decay formula.
The exponential decay formula formula is [tex]Amount=Initial\ value(1-\frac{r}{100} )^{\frac{t}{n} }[/tex]
Here, the value [tex]=5900(1-\frac{0.85}{100} )^{\frac{99}{7} }[/tex]
= 5900×[tex](0.9915)^{14.14}[/tex]

an urn contains two red balls and three white balls. if a ball is chosen at random, what is the probability that it is white?
If an urn contains two red balls and three white balls and a ball is chosen at random, then the probability of getting white ball is 3/5
The number of red balls = 2 balls
The number of white balls = 3 balls
Total number of balls = 2 + 3
= 5 balls
The probability = Number of favorable outcomes / Total number of outcomes
Number of favorable outcomes = Number of white balls = 3
Total number of outcomes = 5
The probability = 3/5
Hence, if an urn contains two red balls and three white balls and a ball is chosen at random, then the probability of getting white is 3/5

A 0. 2 kg red ball is thrown horizontally at a speed of 4 m/s from a height of 3 m. A 0. 4 kg green ball is thrown horizontally from the same height at a speed of 8 m/s. Compared to the time it takes the red ball to reach the ground, the time it takes the green ball to reach the ground is.
The ratio of time that the red ball reaches the ground when compared with the green ball is 2:1
By using the equations of motion we first find the acceleration and time of both the balls using [tex]v^{2} -u^{2} =2as[/tex] and [tex]v=u+at[/tex]
where,
v=final velocity,
u=intial velocity,
a=acceleration,
s=height,
t=time
For the red ball,[tex]v^{2} -u^{2} =2as[/tex], v=4m/s, u=0m/s, s=3m by substitiuting in the equation we get ,
[tex]4^{2} -0^{2} =2*a*3[/tex],
acceleration=a=16/6=8/3,
[tex]v=u+at[/tex] by substituting we get,
4=0+8/3*t,
time taken by the red ball to reach ground t=3/2
For the green ball,[tex]v^{2} -u^{2} =2as[/tex], v=8m/s, u=0m/s, s=3m by substituting in the equation we get ,
[tex]8^{2} -0^{2} =2*a*3[/tex],
acceleration=a=64/6=32/3,
[tex]v=u+at[/tex] by substituting we get,
8=0+32/3*t,
time is taken by the green ball to reach ground t=3/4
and their ratio of time red ball/green ball=(3/2)/(3/4)=2/1,
hence time to reach the ground is independent of their mass
therefore, the ratio of time that the red ball reaches the ground when compared with the green ball is 2:1

Makayla spots an airplane on radar that is currently approaching in a straight line, and that will fly directly overhead. The plane maintains a constant altitude of 5750 feet. Makayla initially measures an angle of elevation of 16^{\circ} ∘ to the plane at point AA. At some later time, she measures an angle of elevation of 31^{\circ} ∘ to the plane at point BB. Find the distance the plane traveled from point A to point B. Round your answer to the nearest foot if necessary.
The distance the plane traveled from point A to point B is 10952 feet approx.
To solve this we have to use the Pythagoras theorem.
Given that the plane is at a constant height which can be supposed as the perpendicular (i.e 5750 feet) for the triangle which the plane , ground and the makayla make.
Now when the plane is at the A point then the angle of the elevation is 16°, so the distance from the makayla the plane is :
tanθ = P/B,
B(distance of makayla to plane on ground at point A) = P/tanθ ,
B = 5750 / tan 16°,
B = 5750/ 0.28;
B1 = 20535 feet approx
Similarly when the plane reach at the point B then the angle of the elevation is 31° then the distance from the makayla and the plane would be different, which will be :
tanθ = P/B,
B(distance of makayla to plane on ground at point B) = P/tanθ ,
B = 5750 / tan 31°
B = 5750 / 0.6
B2 = 9583 feet approx
now the distance traveled by the plane is B1 - B2 :
which is 20535 - 9583

Given m \| nm∥n, find the value of x.

What are corresponding angles?The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.
The (5x + 9)° angle on line m and the (7x - 9)° angle on line n are corresponding angles.
We have given that Line m and Line n are parallel.
t line is the transversal line on the two parallel lines, line m and line n.
We see that,
(5x + 9)° angle on line m is corresponding to the (7x - 9)° angle on line n.
So,
(5x + 9)° + (7x - 9)° = 180
12x = 180
x = 80 /12
x = 6.67
Thus, The value of x is 6.67 degrees.
