Answer:
a
Step-by-step explanation:
Mode refers to a value that appears most frequently in a data set.
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
Median is the number that occurs in the middle of a set of observations
Arranging the numbers in ascending order : 55, 66, 82, 89, 90, 92
median = (82 + 89) / 2 = 85.5
There is no mode because the numbers only appear once
Range = 92 - 55 = 37
mean = 476/6 = 79
Determine whether each expression represents the statement divide the sum 15 and 6 by the difference of 10 and 3.
Answer:
[tex]\frac{15+6}{10-3}[/tex]
Step-by-step explanation:
Sum of 15 and 6 = 15 + 6
Difference of 10 and 3 = 10 - 3
So, the expression is
[tex]\frac {15 + 6}{10-3}[/tex]
This is the required expression.

Answer:
The third option, a rational number
like 1/5 + 2.5 is still rational (but neither irrational nor whole/an integer)
it would be 0.2 + 2.5 = 2.7 btw
or
1/5 + 5/2
= 2/10 + 25/10
= 27/10

Answer:
Step-by-step explanation:
-3x - 5 = 16
add 5 to both sides of the equation
-3x = 21
divide both sides by -3
x = -7
---------------------
-4(y - 2) = 12
distribute the -4 to everything in the parentheses
-4y + 8 = 12
subtract 8 from both sides of the equation
-4y = 4
divide both sides of the equation by -4
y = -1

The measures of the angles of a triangle are shown in the figure below. Solve for x.
54°
Geometry
A right triangle adds up to 180°.
Make an equation to find x.
54°+x°+90°=180°
Add like-terms.
144°+x°=180°
Subtract 144 from both sides.
x°=36

Find the gradient of a line with the following equations 3y+6x =12
Hi there!
[tex]\large\boxed{\text{gradient = -2}}[/tex]
Recall the equation:
y = mx + b, where:
m = slope, or gradient of a line
Rewrite this expression into the above format:
3y + 6x = 12
Isolate y by subtracting 6x from both sides of the equal sign:
3y + 6x - 6x = 0x -6x + 12
3y = -6x + 12
Divide all terms by 3:
y = -2x + 4
Thus, the gradient is -2.
What is the solution to the system of equations?
4x + 2y = 1
5x = y - 18

Describe how the rules of adding and subtracting fraction are similar and different from the rules of adding and subtracting rational expressions. When are excluded values applied and why are they needed? Give an example. This needs to be an in depth answer.
Answer:
To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator.
When the denominators are not the same, we must manipulate them so that they become the same. In other words, you must find a common denominator.

The Cubs are projected to win 38 games next season, this is a 22.6% increase from this past season, how many games did they win in this past season?
Answer:
≈ 30 times
Step-by-step explanation:
The Cubs are projected to win 38 games next season and this is a 22.6% increase from past season.
Step 1 : Let's find 22.6% of 38.
= 8.588
Step 2 : Now, since we increased by this, we subtract.
38 - 8.588 = 29. 412
Of course you can't win only part of a game, so I'm going to say they won 30 times, because a little extra win never hurt anybody. :)

Answer:
A. w+2
Step-by-step explanation:
(w²+2w)/ w =
w(w+2)/w = w+2
Answer:
a) w+2
Step-by-step explanation:
A=w^2+2w
width is w
let's consider length is x
area=length×width
so
[tex] {w}^{2} + 2w = xw[/tex]
[tex]x = \frac{ {w}^{2} + 2w}{w} = w + 2[/tex]
A restaurant charges $100 to rent its banquet room for an event. It also charges $15 to serve dinner to each guest. Write an equation for the total cost (t) of renting the banquet room in terms of the number of guests (g). How many guests attend if the total cost of an event is $2200?
Answer:
t = 100 + 15x
= 140 guests
Step-by-step explanation:
Rent for banquet room = $100
Dinner per guest = $15
Let
x = number of guests
Total cost = Rent for banquet room + (Dinner per guest * number of guests
Total cost, t = 100 + 15x
How many guests attend if the total cost of an event is $2200?
t = 100 + 15x
2,200 = 100 + 15x
2200 - 100 = 15x
2,100 = 15x
x = 2,100/15
x = 140 guests
x = number of guests = 140 guests
Which equation is correct?

Answer:
sin x° = opposite ÷ hypotenuse
Step-by-step explanation:
Cosine is represented by the expression adjacent ÷ opposite and sine is represented by opposite ÷ hypotenuse. Only the fourth option lines up with the functions defined above.
If you are having trouble remembering the ratios for each trig function, you can use the acronym SohCahToa. This stands for:
S - sine
o - opposite
h- hypotenuse
C - cosine
a - adjacent
h - hypotenuse
T - tangent
o - opposite
a - adjacent
