Charles owns a catering business. The amount his 10 most recent clients spent is shown in the histogram below. Why is the graph misleading? The x-axis scale shows the data is more clustered than it actually is. The y-axis scale shows the data is more skewed than it actually is. The scales are different on the x-axis and the y-axis. The data is not distributed equally across the x-axis intervals.
THE ANSWER IS A)The x-axis scale shows the data is more clustered than it actually is.
Youre welcome
The histogram showing the number of events with the events cost is
misleading because;
The x-axis scale shows the data is more clustered than it actually isHow can the histogram be analyzed?Please find attached a possible diagram of the histogram in the question
created with MS Excel;
The data in the histogram is presented as follows;
[tex]\begin{array}{|c|c|c}Event \ Cost&Number \ of \ Events\\1000- 1499&2\\1500-1999&4\\2000-2499&3\\3000-3499&1\end{array}\right][/tex]
From the above table, we have that the class with event cost of 2000 to
2499 is left out, therefore, the data is more clustered.
The correct option is therefore;

A conference will take place in a large hotel meeting room. The organizers of the conference have created a drawing for how to arrange the room. The scale indicates that 1/2 inch on the drawing corresponds to 12 feet in the actual room. In the scale drawing, the length of the room is 3 1/3 inches. What is the actual length of the room?
Answer:
The actual length of the room is 40 feet
Step-by-step explanation:
Given
[tex]Scale = \frac{1}{2}\ inch : 12\ feet[/tex]
Required
Determine the actual measurement of [tex]3\frac{1}{3}\ inches[/tex]
Represent the required actual measurement with x
i.e.
[tex]3\frac{1}{3}\ inches : x[/tex]
And we have:
[tex]\frac{1}{2}\ inch : 12\ feet[/tex]
[tex]3\frac{1}{3}\ inches : x[/tex]
Cross Multiply
[tex]x * \frac{1}{2} = 12 * 3\frac{1}{3}[/tex]
Convert fraction to improper fraction
[tex]x * \frac{1}{2} = 12 *\frac{10}{3}[/tex]
[tex]\frac{x}{2} = \frac{120}{3}[/tex]
[tex]\frac{x}{2} = 40[/tex]
Multiply both sides by 2
[tex]x = 40 * 2[/tex]
[tex]x = 80\ feet[/tex]
The actual length of the room is 40 feet

Rachel has an unknown sample of a radioisotope listed in the table. Using a special technique, she is able to measure the mass of just the unknown isotope as 104. 8 kg at 12:02:00 P. M. At 4:11:00 P. M. On the same day, the mass of the unknown radioisotope is 13. 1 kg. Which radioisotope is in the sample? Potassium-42 Nitrogen-13 Barium-139 Radon-220.
The radioactive isotopes of an element are known as radioisotopes. The radioisotope sample that is given is Barium-139.
What is radioisotope?The radioactive isotopes of an element are known as radioisotopes. Atoms with an unstable mix of neutrons and protons, or excess energy in their nucleus, are also known as neutron-proton atoms.
As it is given that the initial mass of the sample at 12:02:00 PM is,
[tex]m_1=104.8\ kg[/tex]
The Mass of the sample at 4:11:00 PM is given as
[tex]m_2 = 13.1 kg[/tex]
So here since it is a sample of radioactive isotope so here we will say
[tex]m_2=m_1e^{-\lambda t}[/tex]
Now from the above data, we know that the time taken to reduce the mass is
[tex]\rm t = 4\ hours\ 9\ minutes = 4.15\ hours[/tex]
Further, from the above equation, we will have
[tex]13.1 =104.8 e^{-\lambda(4.15)}\\\\\lambda(4.15)=2.08\\\\\lambda = 0.50/ hour[/tex]
So here half-life is given as
[tex]\rm T_{\frac12}=\dfrac{ln2}{\lambda}\\\\ T_{\frac12} = 1.4\ hours[/tex]
Thus, here this isotope must be the one that will have a half-life of 1.4 hours
Therefore, it is nearly Barium-139.
Hence, the radioisotope sample that is given is Barium-139.

How many solutions does this equation have: y=-2x^2+5x-9
Step-by-step explanation:
First we solve it.
I'll use substitution.
In the first equation y equals -2x+2 so we can apply that to the second equation
2y + 4x = 4
2(-2x+2) + 4x = 4
distribute
-4x+4+4x=4
simplify
4=4
To figure out how many solutions it has:
•If both side of the equal sign are exactly the same: Infinitely many
ex: 6x=6x
•If both sides of the equal sign do not match when completely simplified: No solutions
ex: 3x=-5x
•If it creates an equation: 1 solution
ex: x=3+2y
Since both sides of the equal sign are 4, we have infinitely many solutions.

Two trains left a station at the same time. Train A traveled north at a certain speed and train B traveled south
at twice that speed. After 4 hours, the trains were 600 miles apart. How fast was each train traveling?
Train A was traveling
mph... (hint... this is the slower train)
Train B was traveling
mph.
Step-by-step explanation:
Train 1 speed be 'u'
Train 2 speed be 'v'
And v=2u
Speed=distance/time
Trains going in opposite directions
Relative speed= v-u (as train 1 I slower than train 2)
v-u=600/4
2u-u=150
u=150miles/hour
v=300miles/hour

URGENT
Answer:
12
Step-by-step explanation:
Solution:
We know that:
Area of triangular pane = 576 in²Height of triangular pane = 48 inArea of triangle formula = 1/2 x Base x AltitudeSubstituting the height and the area of the pane in the formula
Area of triangle = 1/2 x Base x Altitude = 576 in²1/2 x Base x 48 = 576 in²Simplifying the LHS:
1/2 x Base x 48 = 576 in²Base x 24 = 576 in²Dividing 24 both sides
(Base x 24)/24 = 576/24Base = 576/24 = 24 inThus, the measure of the base is 24 inches.

Answer:
x = 25
Step-by-step explanation:
The sum of the three interior angles of a triangle is always 180°.
4x + 2x + 30 = 180
6x + 30 = 180
6x = 150
x = 25
Answer:
sum of the interior angles of a triangle =180
2× + 4× + 30=180
6× + 30= 180
6× + 30 = 180
6× = 180-30
6× =150
6×/6=150/6
×= 25

Please help me with these. WIll give 20 pts. I will award brainly for the best answer!
Step-by-step explanation:
Ok, so first...
a) if x is positive, it will remain x, so *x<7*
b) if x+3 is positive, it will be x+3<9 but you have to simplify it so you subtract 3 on both sides and get *x<6*
c) if y-8 is positive, it will stay like that, and you then add 8 on both sides to get *y>19*
g) if 3x-1 is positive, it will be 3x-1 greater than or equal to 18. add 1 on both sides and *3x > or = to 18*
4y+3 < or = 13. subtract 3 on both sides and you get *4y < or = 13*
