Students took a typing test. The number of words per minute students could type are listed below. 40, 47, 25, 32, 48, 55, 33, 56, 32, 47, 32 What is the median number of words per minute the students could type?
Answer:
50
Step-by-step explanation:
The median number is known as the middles number
The first step is to rearrange the set of numbers starting from the lowest
25, 32, 32, 32, 33, 40, 47, 47, 48, 55, 56
Hence the middle number is 50

y=9x+17
y=x+49
Answer:
y = 10x + 66
Step-by-step explanation:
I don't know if this is how you wanted me to do it, there was not enough information for me to conclude if this was the correct way to do it. but I added 9x + x and whenever there is a variable without a number in front of it the variable = 1x or whatever the variable is. So 9x + 1x= 10x and 17+49= 66 so put it together and you get y= 10x +66
Answer:
y-9x=17-----1
y-x. =49----2
2-1
y-x-(y-9x)=49-17
y-x-y+9x.= 32
8x =32
x=4
y=4+49
=53
x=4
y=53
solve for t in d =rt if d =57 and r =30. t=
57 = 30 × t
t = 57/30
t = 19 × 3 / 10 × 3
t = 19/10
t = 1.9
Answer:
t = 1.9
Step-by-step explanation:
Given
d = rt
Substitute d = 57 and r = 30 into the equation
57 = 30t ( divide both sides by 30 )
[tex]\frac{57}{30}[/tex] = t , that is
t = 1.9

What is the fraction representation of 0.196 (6 repeating)?
Answer:
49/250 I think I'm not sure though
Answer:
[tex]\frac{59}{300}[/tex]
Step-by-step explanation:
Recall that [tex]\frac{x}{9}[/tex] returns the decimal [tex]0.\overline{x}[/tex]. In this case, we only want the 6 repeating. We can achieve this by finding the fraction excluding the 6 and then adding the repeating fraction with the 6.
0.19 as a fraction is simply [tex]\frac{19}{100}[/tex]
[tex]\frac{6}{9}[/tex] returns a repeating digit 6. However, we would like the 6 to be in the thousands place. Since it's already in the tenth place, we will divide the fraction by 100 to put it in the thousands place: [tex]\frac{6}{9}\cdot \frac{1}{100}=\frac{6}{900}[/tex]
Adding these two fractions, we get:
[tex]\frac{6}{900}+\frac{19}{100}=\frac{6}{900}+\frac{171}{900}=\frac{177}{900}=\boxed{\frac{59}{300}}[/tex]
The interior angle measure of a regular polygon is calculated with the following formula, where n represents the number of sides or interior angles of the regular polygon.
Determine the measure of the interior angles of a regular octagon and identify whether or not a regular octagon can be used as the only shape in a regular tessellation.
144°, no
135°, yes
144°, yes
135°, no
THE RIGHT ANSWER IS A 144°, no
Answer:
Step-by-step explanation:
The interior angle measure of a regular polygon is calculated with 180*(n-2)/n, where n represents the number of sides.
A regular octagon has 10 sides so it interior angle = 180*(10-2)/10
= 144
A tessellation is a tile pattern with the same polygon repeating. The polygon's interior angles must combine to form 360 degree. A regular octagon has interior angle of 144 degree which does not add to 360 degree. So a regular octagon cannot be used as the only shape in a regular tessellation.
The answer is 144°, no.
Answer:
Step-by-step explanation:
oct means 10
(n-2)/n * 180
= (10-2)/10 * 180
= 144°
144 + 144 = 288 < 360
144 + 144 + 144 = 432 > 360
so a regular octagon can NOT be used as the only shape in a regular tessellation.

Step-by-step explanation:
[tex] \frac{ {a}^{2} - bc}{b} = \frac{ {12}^{2} - 6 \times 3}{6} = \frac{144 - 18}{6} = \frac{126}{6} = 21[/tex]
the price of a photography machine in RS60000.find the price after inculding13%tax
Answer:
Rs. 67800
Step-by-step explanation:
Price of photograph = 60000 = 100%
Tax = x dollars = 13% of 60000
100% + 13% = 113% = 1.13
Multiply
1.13(60000) = 67800
To check, lets find 13% of 60000 and add to 60000
13% = 0.13
0.13(60000) = 7800
60000 + 7800 = 67800
Units = Rs
Rs. 67800

a small chocolate sundae costs $3. each topping you add costs $0.50. how much would it cost to get a small sundae with P toppings added?
Answer:
3=0.5p
Step-by-step explanation:
The cost to get a small sundae with P toppings added represented as 3 + 0.5p.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let's consider the toppings added to the chocolate sundae represented by p.
We will use the unitary method,
The cost of topping added to one chocolate = $0.50
The cost of topping added to p chocolate = $0.5p
So, the cost to get a small sundae with P toppings added is;
3 + 0.5p
Therefore, the cost to get a small sundae with P toppings added represented as 3 + 0.5p

7) [tex]x \to x - 3[/tex].
8) [tex]y \to y + 2[/tex]
9) The entire quadratic equation did not get reflected.
Step-by-step explanation:
7) A horizontal translation to the right is of the form:
[tex]x \to x - a[/tex]
Let [tex]y = -(x-3)^{2} + 2[/tex], then the horizontal translation is represented by [tex]x \to x - 3[/tex].
8) A vertical translation upwards is of the form:
[tex]y \to y + a[/tex]
Let [tex]y = -(x-3)^{2} + 2[/tex] , then the vertical translation is represented by:
[tex]y \to y + 2[/tex]
9) The only component of the quadratic equation that was reflected was the part [tex](x-3) ^{2}[/tex] along the x-axis. We can create the entire function by applying the following steps:
(i) [tex]f(x) = x^{2}[/tex] (Original function)
(ii) [tex]f(x) = (x-3)^{2}[/tex] (Horizontal translation)
(iii) [tex]f(x) = - (x-3)^{2}[/tex] (Reflection)
(iv) [tex]f(x) = -(x-3)^{2} + 2[/tex] (Vertical translation)
The entire quadratic equation did not get reflected.

The solution to the quadratic equation x² - 4x + 1 = 0 is x = ( 4 ±√12 ) / 2
What is the solution to the quadratic equation?A quadratic equation in its standard form is expressed as;
ax² + bx + c = 0
Where x is the unknown
To solve for x, we use the quadratic formula
x = (-b±√(b² - 4ac)) / (2a)
Given the quadratic equation in the question;
x² - 4x + 1 = 0
a = 1b = -4c = 1We substitute this values into the quadratic formula above and solve for x.
x = (-b±√(b² - 4ac)) / (2a)
x = ( -(-4) ±√( (-4)² - ( 4 × 1 × 1)) / (2 × 1)
x = ( 4 ±√( 16 - 4) ) / (2)
x = ( 4 ±√12 ) / 2
Therefore, ( 4 ±√12 ) / 2 is the solution to the equation.
Option C) ( 4 ±√12 ) / 2 is the correct answer.
