What is the mean of the data?

Mathematics
1 answer:
dmitriy555 [2]3 years ago
5 0

Answer:

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

Answer:

\displaystyle f(x)=\frac{1}{x(x-3)}

Option C.

Step-by-step explanation:

<u>Asymptotes Of A Rational Function</u>

We can easily recognize if x=a is a vertical asymptote of a given function f(x) because its graph tends to quickly increase or decrease getting closer to the vertical line x=a but never actually touching it.

We can see in the graph provided, there are two vertical lines, one at x=0 and the other at x=3 (assuming the x-scale is 2). It means the denominator tends to zero at both of those values, i.e. there must be factors like (x-0)(x-3)=x(x-3). The only option with these characteristics is the last one

\boxed{\displaystyle f(x)=\frac{1}{x(x-3)}}

How are radical expressions and polynomial expressions similar?
mote1985 [20]
If you want to add radicals then radicals should be same as variables in polynomial expressions. If radicals are not equal in nature then we cannot add them. In the case of polynomials, if the variables are not same then we cannot add them. The variables should have the same exponents over them.

Rain which falls onto a flat rectangular surface of length 6 m and width 4 m is collected in a cylinder of internal radius 20 cm
Snezhnost [94]

\large\pink{\sf{Given:-}}

  • Length = 6m
  • Width = 4m
  • Height = 1cm
  • Internal Radius of cylinder = 20 cm

\large\purple{\sf{Solution:-}}

\tt \: volume = length \times width \times height

\tt \: volume = 6 \times 4 \times  1

\tt \: volume = 24m ^{3}

<h3>Volume of water in cylindrical vessel;</h3>

\sf\pi \: r ^{2} h

  • r = 20
  • h = ?
  • π = 22/7

\sf \: h =  \frac{volume}{\pi r^{2} }

\sf \: h =  \frac{24 \times 7}{22 \times 20 \times 20}

\sf \: h = 0.190 \: cm

<em>Therefore, The height of cylinder will be 0.190 I'm approximately...</em>

How many gallons of a 80% antifreeze solution must be mixed with 80 gallons of 15% antifreeze to get a mixture that is 70% antif
konstantin123 [22]

440 gallons of 80 % antifreeze solution must be mixed with 80 gallons of 15% antifreeze to get a mixture that is 70% antifreeze

<em><u>Solution:</u></em>

Let "x" be the gallons of 80 % antifreeze added

Therefore, "x" gallons of 80 % antifreeze solution must be mixed with 80 gallons of 15% antifreeze

Final mixture is x + 80

Therefore, we can frame a equation as:

"x" gallons of 80 % antifreeze solution must be mixed with 80 gallons of 15% antifreeze to get (x + 80) gallons of 70 % antifreeze

Thus, we get,

x gallons of 80 % + 80 gallons of 15 % = (x + 80) gallons of 70 %

x \times \frac{80}{100} + 80 \times \frac{15}{100} = (x+80) \times \frac{70}{100}\\\\0.8x + 80 \times 0.15 = (x+80) \times 0.7\\\\0.8x+12 = 0.7x+56\\\\0.8x-0.7x=56-12\\\\0.1x = 44\\\\x = \frac{44}{0.1}\\\\x = 440

Thus 440 gallons of 80 % antifreeze solution must be mixed
