Answer:
Chill, it ain't complicated
Step-by-step explanation:
A histogram is basically a bar graph but there's no space between the bars.
The graph has to be the dependent component (the score) against the independent component (the number of students who took the math quiz)
Depending on your size of paper pick a simple scale (1 cm could be either 5% or 10%)
Leave some space between the y (vertical) axis and the first bar.
Do them in the order they appear, i.e 75, 95... 80
A taxicab service charges customers by the mile. The graph
shows the number of miles a taxicab drives and the amount of
money the customer pays.
Which statement best describes the rate of change for the
situation?
The amount a customer pays increases $0.50 per
mile driven
The amount a customer pays increases $0.60 per
mile driven
The amount a customer pays increases $12 per mile
driven.
The amount a customer pays increases $21 per mile
driven
Answer:
The second option: The amount a customer pays increases $0.60 per mile driven.
Step-by-step explanation:
As seen on the graph, we are given the points (20,12) and (35,21).
This means that at 20mi driven, the amount paid is $12, and at 35mi driven, the amount is $21.
To find the rate of change we divide the distance driven by the cost to find the cost per mile:
20/12 = 0.6
35/21 = 0.6
The slope is 0.6, so it costs an extra $0.6 for every mi driven. Therefore it is the second option: The amount a customer pays increases $0.60 per mile driven.
Hope this helped!
Answer:
The amount a customer pays increases $0.60 per mile driven.
Step-by-step explanation:
$0.6/mi is the rate of change, y = mx + b, so m.is also called rate of change & b is the initial value of x, in the graph b = 0. making m the subject of the equation, then m(roc) = 0.6.
What is the product of 3/5x4/9
Answer: 4/15
For fraction multiplication, multiply the numerators and then multiply the denominators
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 12 and 45 using
GCF(12,45) = 3
Therefore: it's 4/15

List the missing terms from the table.
Using a geometric sequence, it is found that the missing terms of the table are, respectively, given by:
[tex]243, 1, \frac{1}{81}[/tex]
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
From the table, we get that the common ratio is of [tex]q = \frac{1}{3}[/tex], hence each term is the previous divided by 3, or the next multiplied by 3. Hence, the missing terms are given by:
[tex]3 \times 81 = 243[/tex]
[tex]3 \times \frac{1}{3} = 1[/tex]
[tex]\frac{1}{27} \times \frac{1}{3} = \frac{1}{81}[/tex]

A measurement is taken to be 13.6 in. and the absolute error is 0.05 in. What
is the percent of error? Round off your answer to 3 decimal places. *
Given parameters:
True value of measurement = 13.6in
Absolute error = 0.05in
Unknown:
Percent of error = ?
Solution:
Error is an inconsistency introduced into a particular data set or reading.
% error = [tex]\frac{absolute error}{true value}[/tex] x 100
% error = [tex]\frac{0.05}{13.6}[/tex] x 100 = 0.368%
Percent error is 0.368%

d.
all of the above
Please select the best answer from the choices provided
A

C
D
Answer:
the answer is D.all of the above
Step-by-step explanation:
The ozone layer helps to sustain terrestrial life by absorbing incoming UV radiation.
Option A is the correct answer.
What is an ozone layer?The ozone layer is a layer of gas in the Earth's stratosphere that helps to protect the planet from the harmful effects of ultraviolet (UV) radiation from the sun.
We have,
UV radiation can cause damage to living organisms, such as skin cancer, cataracts, and other health problems.
The ozone layer absorbs much of this radiation, preventing it from reaching the Earth's surface and thus helping to sustain terrestrial life.
Option B is incorrect because the ozone layer is located in the stratosphere, above the troposphere.
Option C is incorrect because while the ozone layer can play a role in maintaining the Earth's temperature, its primary function is to absorb UV radiation.
Option D is incorrect.
Thus,
The ozone layer helps to sustain terrestrial life by absorbing incoming UV radiation.

7. Write the explicit formula for the geometric
sequence 32, 16, 8, 4,...
Answer:
The sequence is the ratio of 4:8, or 16:32. This is because the sequence needs to be divided into 2 different factors in order for it to match. The sequence is...
add 4, add 8, add 16, continue on.
The formula is...
4 * x = sequence
In this case, x is the increasing factor. I substituted it due to the fact that it's a constantly increasing number, not just a straight-up number we can declare.

Answer: y = (1/7) x - 2
Step-by-step explanation:
The slope-intercept form of an equation is y = mx + b, where m is the slope and b is the y-intercept.
The slope of an equation is the change in y over the change in x.
We can see from the image that every time the line increases by 1 in the rise (y), it increases by 7 in the run (x).
Therefore, the slope is 1/7.
The y-intercept of a line is the point at which it intercepts the y-axis.
From the image, we can see that it intersects at the point (0,-2)
Therefore, the slope-intercept form is y = (1/7) x - 2
Take two points
(0,-2)(-7,-3)Slope:-
[tex]\\ \sf\longmapsto \dfrac{-1}{-7}=\dfrac{1}{7}=m[/tex]

[tex]\frac{1}{a^{7} }[/tex]
Step-by-step explanation:
Use this rule:

So, this gives you
[tex]a^{-13+6}[/tex]
This equates to:
[tex]a^{-7}[/tex]
However, we cant leave the exponent negative, so we use this formula:
[tex]a^{-b}=\frac{1}{a^b}[/tex]

Answer:
There is no denominator a^-7
The power is positive 1/a^7
Step-by-step explanation:
Remark
We are not told what the restrictions on the power are. Here are the possibilities.
There is no denominator.The power must be positive.So I will give the answer to both conditions. You will have to choose.
There is no denominator
That means that The powers are subtracted
Multiply numerator and denominator by a+6
a^- 13 * a^6
=========
a^-6 * a^6
To start a^(-6 + 6) = a^0 which = 1. That is not written, so you are left with a^ (-13 + 6) = a ^ -7
The answer must have a positive power.
Multiply the numerator and denominator by a^13.
numerator
a^-13 * a^13
a^(-13 + 13)
a^0
1
So we are left with 1 in the numerator.
a^-6 * a^13
a^(-6 + 13)
a^7
Answer: what is left is 1/a^7
Which of these statements best describes a biased sample?
A. The sample is small
B. The sample has results that are incorrect predictions
C. The sample does not accurately represent the population
D. The sample was chosen randomly
A biased sample is best described by:
C. The sample does not accurately represent the population.
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample, which is a group of members of this population. The sample has to be representative of the population, that is, it has to involve all of it's groups. If it does not involve all the groups, it is not an accurate representation of the population, and is called biased, hence option C is correct.

what is an equation of the line that passes through the point (5, -7) and has a slope of 0
Answer:
y=-7
Step-by-step explanation:
Simple enough. Slope of zero means that x does not have to be determined. So if you just put the y coordinate in a slope of zero, you should get your answer.
The equation of line is y = -7.
Equation of line is,
[tex]y=mx+c[/tex]
Where m is slope.
Given that, slope is 0.
Equation of line become, [tex]y=0*x+c=c[/tex]
And Line passes through the point (5, -7)
Substitute these point,
[tex]c=-7[/tex]
Hence, equation of line is, [tex]y=-7[/tex]
