Yes, it is true that data from the frequency table can be used to make a scaled bar graph.
What is a bar graph?A bar graph is a graphical depiction of information, amounts, or numbers using bars or strips. They are utilized to contrast and compare various data types, frequencies, or other measurements of several categories of data.
The number of times a specific value appears in the data is its frequency (f). A variable's distribution is its frequency pattern, or the collection of all conceivable values and the frequencies corresponding to those values. Frequency tables or charts are used to represent frequency distributions.
so bar graphs can be made by frequency table because, To compare the frequency of one category or attribute with that of another, a bar graph is employed. The frequency for each category or attribute is displayed in the bar's height (if vertical) or length (if horizontal).
Hence it is true to make a bar graph from a frequency table.

Answer:
Step-by-step explanation:
y = -x + 2 -------(i)
2x - y = -5 -----------(ii)
Substitute y = -x + 2 in equation (ii)
2x - (-x + 2) = -5
2x + x - 2 = - 5
3x - 2 = -5 {add 2 to both side}

PLEASE HELP! The density of atmosphere (measured in kilograms/meter) on a certain planet is found to decrease as altitude increases (as measured from
the planet's surface). What type of relationship exists between the altitude and the atmospheric density, and what would the atmospheric
density be at an altitude of 1.291 kilometers?
Answer:
The relationship that exist between the altitude and the atmospheric density is an inverse relationship.
[tex]D = \frac{k}{1291} kg/m^3[/tex]
Step-by-step explanation:
since the density of the atmosphere decreases as the altitude increases, the relationship that exist between the altitude and the atmospheric density is an inverse relationship. This can be represented by:
[tex]D = \frac{k}{H}[/tex], where k is the constant, H is the altitude in meters and D is the atmospheric density in kg/m.³
When the altitude is 1.291 km, i.e H = 1.291 km = 1291 m,the atmospheric density D is:
[tex]D = \frac{k}{1291} kg/m^3[/tex]

What are the slope and the y-intercept of the linear function that is represented by the graph?
On a coordinate plane, a line goes through points (negative 3, 0) and (negative 2, 4).
The slope is 3, and the y-intercept is 9.
The slope is 3, and the y-intercept is 12.
The slope is 4, and the y-intercept is 9.
The slope is 4, and the y-intercept is 12.
Answer:
The slope is 4, and the y-intercept is 12.
Step-by-step explanation:
In the given question, the line goes through points (-3,0) and (-2,4).
We need to find the slope and the y-intercept of the line.
Finding Slope:Slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
With points (-3,0) and (-2,4):
[tex]m=\frac{4-0}{-2-(-3)}=\frac{4}{1}=4[/tex]
The slope of the line is 4.
Finding y-intercept:An appropriate equation for what we have so far is:
[tex]y=4x+b[/tex]
We can solve for 'b' to get the y-intercept.
Replace 'x' and 'y' with one of the coordinates and solve for 'b':
[tex]4=4(-2)+b\\4*-2=-8 \leftarrow \text {Distribute}\\4=-8+b\\4+8=-8+8+b \leftarrow \text {Addition Property of Equality} \\\boxed {12=b}[/tex]
The y-intercept is 12.
Final Answer:The answer should be: "The slope is 4, and the y-intercept is 12."
Answer:
The answer is d, which is the slope of 4 and the y- intercept is 12.

UPS charges $6.00 for the first pound, $1.00 for the second pound, and $0.15 for each additional pound. FedEx charges $4.00 for the first pound, $2.00
for second pound, and $0.25 for each additional pound. How many pounds, p. will it take for UPS and FedEx to cost the same?
Complete the equation that represents this situation.
Answer:
12 pounds
Step-by-step explanation:
It takes 12 pounds for the UPS and FedEx packages to cost the same amount to ship.
What is equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, UPS charges $6.00 for the first pound, $1.00 for the second pound, and $0.15 for each additional pound. FedEx charges $4.00 for the first pound, $2.00 for the second pound, and $0.25 for each additional pound.
Equations to represent the situation in this problem.
x=weight of package
UPS cost=6+1+0.15(x-2)
UPS cost=6+1+0.15x-0.3
UPS cost=6.7+0.15x
FedEx cost=4+2+.25(x-2)
FedEx cost=4+2+0.25x-0.5
FedEx cost=5.5+0.25x
Next, we can set the two equations equal to each other to solve for x.
6.7+0.15x=5.5+0.25x
6.7+0.15x-5.5=5.5+0.25x-5.5
1.2+0.15x-0.15x=0.25x-0.15x
1.2/0.1=0.1x/0.1
x=12
Hence, It takes 12 pounds for the UPS and FedEx packages to cost the same amount to ship.

A jeweler sells gems at a cost in dollars per centigram that is 4 more than 6 times the weight of the gem in centigrams.
Thus, a gem that weighs w centigrams will be sold at a price of 6w + 4 dollars per centigram - meaning that a larger,
heavier gem will cost more per centigram than a smaller gem. If the jeweler sold a single gem for about $2500, what
did the gem weigh to the nearest centigram?
Answer:
416 centigrams
Step-by-step explanation:
2500 = 6w + 4
2496 = 6w
416 = w
The amounts of Cathy’s last six clothing purchases were $109, $72, $99, $15, $99, and $89. For each question, choose the mean, median, or mode and give its value.
C.) Which value would Cathy NOT tell her parents to convince them that she needs an increase in her allowance?
{I only need help on part C}
Answer:
The mean value = $80.5
Step-by-step explanation:
The value of her last six spendings are $109, $72, $99, $15, $99, and $89.
For the mean.
Mean = Total spendings/number
Mean =483/6
Mean = $80.5
For the median.
Lets arrange it in ascending order
$15 ,$72, $89, $99, $99, $109
The middle values are two.
Median = (89+99)/2
Median = 188/2
Median = $94
For the mode
$15 ,$72, $89, $99, $99, $109
Highest occuring is $99 with two frequencies.
To convince her parents that she needs an increase in allowance she would show them the bigger spendings .
So the least value on the list it's mean value which is $80.5.

How are the solution sets to s<3 and |s|<3 different ?
Answer:
The solution set for [tex]s<3[/tex] would be (-∞,3)
The solution set for [tex]|s|<3[/tex] would be (-3,3)
Step-by-step explanation:
The solution set for [tex]s<3[/tex] can be any number that is lower than 3.
When we have the inequality [tex]|s|<3[/tex], we need to rewrite this without the absolute values to find our answer
[tex]|s|<3[/tex]
[tex]s<[/tex] ± [tex]3[/tex]
This can be be split into [tex]s<3, s<-3[/tex]
But, there one thing that needs to be done to the inequality with the-3. As we multiplied it by a -1 to make it negative, we must reverse the sign of the inequality. This leaves us with [tex]s<3, s>-3[/tex]
Now, we can combine these to get one inequality

Two sides and an angle (SSA) of a triangle are given. Determine whether the given measurements produce one triangle, two triangles, or no triangle at all. Solve each triangle that results.
a equals 9 comma
b equals 8 comma
A equals 50 degrees
Answer:
B = 42.9°
C = 87.1°
c = 7.4
Step-by-step explanation:
In this problem we are given two sides and one angle of a triangle ABC. The given values are:
a = 9
b = 8
A = 50°
In this case, there wil be only one solution, because the side opposite the given angle (side a) is longer than side b that was also given.
Calculating, let's the the law of sines.
[tex] \frac{sin A}{a} = \frac{sin B}{b} = \frac{sin C}{c} [/tex]
[tex] \frac{sin 50}{9} = \frac{sin B}{8} = \frac{sin C}{c} [/tex]
Taking for A & B, we have:
[tex] \frac{sin 50}{9} = \frac{sin B}{8} [/tex]
Let's cross multiply
(sin 50°)(8) = 9 sinB
Solving further,
[tex]sin B = \frac{8 sin 50}{9}[/tex]
[tex] sin B = \frac{6.128}{9}[/tex]
[tex] B =sin^-^1(0.68)[/tex]
B = 42.9°
Since the total angle of a triangle is 180°, to find C, we have:
C = 180 - 50 - 42.9
C = 87.1°
To find the length of c, let's also use the sine formula.
[tex]\frac{sin B}{b} = \frac{sin C}{c} [/tex]
[tex]\frac{sin 42.9}{8} = \frac{87.1}{c} [/tex]
Cross multiplying
8c = 87.1 sin 42.9
[tex] c = \frac{87.1 sin42.9}{8} [/tex]
c = 7.4
