sure to label the axes.
b. How does the graph show the cost per ticket? How is
this cost related to the equation?
Answer:
8 would be A and b would be 4
please help me with these two problems
Problem 1
With mean = median, the data set is symmetrical. Well it's more accurate to say "roughly symmetrical" due to the phrasing "mean is approximately equal to the median". Using the median as its center is fairly common with many distributions, so there isn't an issue here.
The error is from the phrasing "the quartiles should be used to measure the spread". The quartiles themselves don't measure spread. They are simply single data points and do not tell us the spread. If Ralph said Q3 = 75 is a measure of spread, then he would be incorrect. However, the difference between the third and first quartile will help get the IQR (interquartile range), as described by this equation below
IQR = Q3 - Q1
and this is one tool to measure how spread out data is. The larger the IQR is, the more spread out the data will be.
The IQR is how far of a gap it is from Q1 to Q3. Another tool to measure spread is the standard deviation. Ralph was probably thinking about the IQR when he mentioned the quartiles, but he should be more specific about what he means.

Problem 2
Answer: Skewed left
This is the same as saying "negatively skewed"
---------------
Explanation:
The main cluster of values is on the right side, while a small portion of values are to the left. We consider this the left tail and the left tail is pulled longer compared to the right tail. The further left we go, the shorter the bar and eventually we hit outliers. These much smaller outliers compared to the main cluster pull on the mean to make it smaller than it should be.
One example could be that this curve represents test scores. The majority of the class could get in the range of say 70 to 90. Then there's the unfortunate few outliers who scored much lower (possibly 40 through 60); those outlier scores pull down the mean grade of the class overall.
In short, negatively skewed data indicates that mean < median.

no they don't
Step-by-step explanation:
leah has a higher goal-assist ratio with 1 more assist than maddie
What is the area of the front face?
Answer:
the area of the front face would be 40 square inches.
Step-by-step explanation:
to find the are of a rectangle, you multiply the length times the width. we can see that the length is 8 inches at the bottom of the front face and we can see that width is 5 inches next to the left side face. if we take those two numbers (5 and 8) and multiply them, we get 40. all you have to do after that is add "square inches" to the end because when you find the area of something, it will be squared and the measurement used in inches.
What is the answer to this question? The difference of x and 22 is equal to 8
Answer:
If the difference of x and 22=8
then equation is
X -22=8
X=22+8
X=30
therefore now we put the value of x in the equation
30-22=8
8=8
Answer:
x would be 30
Step-by-step explanation:
x-22=8
x=8+22
x=30
what is the total surface area of the rectangle prism? Help me please someone ASAP!
Answer:
B) 256
Step-by-step explanation:
w = 4
l = 12
h = 5
Formula:
SA = 2(wl + hl + hw)
SA = 2(4*12 + 5*12 + 5*4)
SA = 2(48 + 60 + 20)
SA = 2(128)
SA = 256

Answer:
X=-2
Step-by-step explanation:
1. Open up the brackets
You then get
6+8x+12=2
2. Send the whole numbers to the other sides
8x= 2-6-12
8x = - 16
3. Divide both sides by 8 to leave x alone
X=-2

Which figure has been packed with unit cubes correctly without gaps or overlaps?
a rectangular prism partially filled with unit cubes
a rectangular prism completely filled with unit cubes
a rectangular prism partially filled with unit cubes
a rectangular prism partially filled with unit cubes
Answer:
Second option: a rectangular prism completely filled with unit cubes
Step-by-step explanation:
If the rectangular prism is completely filled then there are 1) no gaps, 2) no overlaps. It's compact and complete.

bill js a builder. On Monday he msde mortar mix. he used 24kg of sand and 5kg of cement. on tuesday bill will make the same type of mortar mix. he will use 36kg of sand. how much cement does he need to make the same type of mortar mix?
Answer: 7.5kg
Step-by-step explanation:
Since Bill made mortar mix and he used 24kg of sand and 5kg of cement. This means that for 1 kg of cement, (24/5) = 4.8 kg of sand is used.
Therefore, when he uses 36kg of sand, the kg of cement used will be:
= 36 / 4.8
= 7.5 kg
Therefore, he'll use 7.5kg of cement and 36kg of sand.

Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y = mx + b
"m" is slope
"b" is y-intercept (coordinates are (0, b)
Parallel lines have the same slopes and different y-intercepts.
Slopes of perpendicular lines are opposite reciprocals: [tex]m_{1}[/tex] × [tex]m_{2}[/tex] = - 1

Factor the expression 12x - 9y + 15
Answer:
3(4x - 3y + 5)
Step-by-step explanation:
Since all coefficients are divisible by 3 (12/3 = 4, 9/3 = 3, 15/3 = 5):
3*4x - 3*3y + 3*5 = 3(4x - 3y + 5)
Give l m n find the value of x
Answer:
x=13
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
9x+17 + 3x+7 = 180
Combine like terms
12x +24 =180
Subtract 12 from each side
12x+24-24 =180-24
12x =156
Divide each side by 12
12x/12 =156/12
x=13
