Which term best describes the shape of this distribution?
skewed right
skewed left
normal
uniform
Answer:
This looks like a UNIFORM distribution. There is no skewed and it's not a 'normal' distribution, which would be like a hill. does that make sense?
The image is showing the uniform distribution. The correct option is D.
What is uniform distribution?The continuous uniform distribution or rectangular distribution is a family of symmetric probability distributions in probability theory and statistics. The distribution describes an experiment in which the outcome is arbitrary and falls between certain bounds.
It can be also defined as a uniform distribution is a type of probability distribution in which every possible outcome has an equal chance of occurring.
Given that the in the image there are vertical bars showing the approximate uniformity of the data.
Here, the data is varying uniformly therefore the shape is describing the uniform distribution.

Answer:
3x - y = 2
Step-by-step explanation:
pick 2 points on the line: (0, -2), (2, 4)
find slope (m):
m = (4-(-2))/(2-0) = 6/2 = 3
write the equation in point-slope form first:
y - y1 = m(x - x1)
plug in a point: (2,4)
y - 4 = 3(x - 2)
y - 4 = 3x-6
now write it in standard form: Ax + By = C
3x - 6 = y - 4
3x - y = 2
A research organization reported that 41 percent of adults who were asked to describe their day responded that they were having a good day rather than a typical day or a bad day. To investigate whether the percent would be different for high school students, 600 high school students were randomly selected. When asked to describe their day, 245 students reported that they were having a good day rather than a typical day or a bad day. Do the data provide convincing statistical evidence that the proportion of all high school students who would respond that they were having a good day is different from 0.41 ?
A) No, because the p value is less than any reasonable significance level
B) No, because the pvalue is greater than any reasonable significance level
C) Yes, because the p-value is less than any reasonable significance level
D) Yes, because the pvalue is greater than any reasonable significance level
E) Yes, because the expected value of the number of students who will report having a good day is 246, not 245.
Answer:
B) No, because the p-value is greater than any reasonable significance level
Step-by-step explanation:
H-null: p = 0.41
H-alt: p =/= 0.41
1 proportion Z test
On a calculator: stat + tests + 5
p: .41
x: 245
n: 600
prop: =/= p
This gives a p-value = .934
(standard significance level is .05, so this p-value is much larger)
fail to reject H-null
If the p-value is much larger than 0.41 then the null hypothesis is rejected. Then the correct option is B.
What are null hypotheses and alternative hypotheses?In null hypotheses, there is no relationship between the two phenomenons under the assumption or it is not associated with the group. And in alternative hypotheses, there is a relationship between the two chosen unknowns.

The equation of the straight line in slope - intercept form that
is perpendicular to the given line and passes through the point (0, 9) is -
y = 6x + 9.
What is the general equation of a straight line?The general equation of a straight line is -
y = mx + c
where -
{m} is the slope of the line.
{c} is the {y} - intercept.
Given is that the equation of a straight line as -
2x + 12y = - 1
Assume that the equation of the straight line in slope - intercept form as
y = mx + c
Now, the given straight line is perpendicular to the given line. So, we can write the slope as -
{m} = -1/(-1/6)
{m} = 6
For the {y} intercept, we can write -
{c} = 9
So, we can write the equation of the straight line in slope - intercept form that is perpendicular to the given line and passes through the point (0, 9) is -
y = 6x + 9
Therefore, the equation of the straight line in slope - intercept form that
is perpendicular to the given line and passes through the point (0, 9) is -
y = 6x + 9.

Looking out from a balcony, the angle of elevation to the top of the next building is
approximately 22 degrees. The angle of depression to the bottom of the building is
approximately 29 degrees. If the building is 200 feet away, how tall is it?
Answer:
191.67 feets
Step-by-step explanation:
From. The attached picture :
Height x can be obtained using trigonometry :
Tan 22 = x / 200
0.4040262 = x / 200
x = 0.4040262 * 200
x = 80.805245 feets
For height, y :
Tan 29 = x / 200
0.5543090 = x / 200
y = 0.5543090 * 200
y = 110.86181 feets
Building height = x + y
Building height = 80.805245 + 110.86181 = 191.67 feets

Find the missing side or angle.
Round to the nearest tenth.
A=15°
C= 120°
b=3
c=[? ]
Enter
Given:
[tex]A=15^\circ, C=120^\circ,b=3[/tex].
To find:
The length of side c.
Solution:
According to the angle sum of property of a triangle, the sum of all interior angles of a triangle is 180 degrees.
[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]
[tex]15^\circ+m\angle B+120^\circ=180^\circ[/tex]
[tex]m\angle B+135^\circ=180^\circ[/tex]
[tex]m\angle B=180^\circ-135^\circ[/tex]
[tex]m\angle B=45^\circ[/tex]
According to the Law of sines,
[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
Using Law of sines, we get
[tex]\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
[tex]\dfrac{3}{\sin 45^\circ}=\dfrac{c}{\sin 120^\circ}[/tex]
[tex]\dfrac{3}{\dfrac{1}{\sqrt{2}}}=\dfrac{c}{\dfrac{\sqrt{3}}{2}}[/tex]
[tex]3\sqrt{2}\times \dfrac{\sqrt{3}}{2}=c[/tex]
On further simplification, we get
[tex]\dfrac{3\sqrt{6}}{2}=c[/tex]
[tex]3.674235=c[/tex]
[tex]c\approx 3.7[/tex]
Therefore, the length of side c is about 3.7 units.
whats the second step of calculating the present value of an ordinary annuity by table lookup
The second step of calculating the present value of an ordinary annuity by the table lookup is to look up the periods and rates in the PV annuity table.
What is the present value of an ordinary annuity?The present value of an ordinary annuity is the current value based on future cash inflows of the annuity, given a specified discount rate.
The present value is higher when the discount rate is lower, and vice versa.
The present value of an ordinary annuity, which discounts the annuity to the current time, is computed as Annuity Payment x Present value of the ordinary annuity table.
In conclusion, an annuity simply means a series of periodic payments and may involve payment at the beginning (annuity due) or at the end of the period (ordinary annuity).

5x2 = 10 (5 + 5)
5x3 = 15 (5 + 5 + 5 [10 + 5])
5x4 = 20 (5 + 5 + 5 + 5 [15 (5x3) + 5)

Which measure of variation should you use to describe
two data sets that are both not symmetric?
Answer:
Mean absolute deviation (MAD).
Step-by-step explanation:
A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.
In statistics and probability, random variables are either continuous or discrete.
1. A continuous random variable is a variable that has its possible values as an infinite value, meaning it cannot be counted.
Example are the height of a randomly selected person, time it take to move from Texas to New York city, etc.
2. A discrete random variable is a variable that has its possible values as a finite value, meaning it can be counted.
Examples are the number of light bulbs that burn out in the next year in a room with 19 bulbs, the number of chicken in a district etc.
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
The mean absolute deviation also referred to as mean deviation can be defined as the average of the distance or absolute deviations between the central point of a data set. Thus, it used by statisticians to illustrate the variability or statistical dispersion in a data set.
Mean absolute deviation (MAD) is a measure of variation that should be use to describe two data sets that are both not symmetric i.e they are skewed and as such not having a mirroring image.
