The dot plot represents the length of practice time in minutes for the math competition. Explain how the outlier of the data affects the statistical summary of the data.
Select the answers from the drop-down menus to complete the statements.
The mean practice time
Choose... (decreases, increases, does not change)
because of the outlier.
The median practice time
Choose... (decreases, increases, does not change)
because of the outlier.
The range
Choose... (decreases, increases, does not change)
because of the outlier.
Using statistical concepts, it is found that:
The mean practice time decreases because of the outlier.The median practice time does not change because of the outlier.The range increases because of the oulier.What are the mean, the median and the range of a data-set?The mean is the sum of all observations divided by the number of observations.The median is the middle value, the value that separates the upper 50% from the bottom 50%.The range is the difference between the largest value and the smallest.From their concepts above, we have that the mean and the range are influenced by outliers.
In this problem, the outlier is at the low end, of 15, hence:
The mean practice time decreases because of the outlier.The median practice time does not change because of the outlier.The range increases because of the oulier.More can be learned about statistical concepts at https://brainly.com/question/24732674

Help please!!! At a baseball game, a vender sold a combined total of 236 sodas and hot dogs. The number of sodas sold was three times the number of hot dogs sold. Find the number of sodas and the number of hot dogs sold.
Answer:
56 hotdogs, 168 sodas.
Step-by-step explanation:
# of sodas sold = s
# of hotdogs sold = h
224 sodas and hotdogs = s + h
3h = s
224 = h + s
Plug in one equation into the other one, like 3h = s into h + s
h + s = 224 and s = 3h so...
h + (3h) = 224
4h = 224
h = 224/4 = 56
56 hotdogs were sold
And since s = 3h...
The number of sodas sold is 3 times 56 = 168 sodas.
56 hotdogs, 168 sodas.
Answer:
56 hotdogs, 168 sodas.

Can someone please help me with this?? Thanks :)
Answer:
m<2=60
m<1=120
m<3=120
Step-by-step explanation:
Since m<4=60 that transfers to m<2 also because they are equal. To find the other to angles you have to subtract 60 from 180 because m<1 and m<4 create a straight line that equals 180. That then also transfers to m<3.
Thank you have an amazing day.

Multiply the binomials:
Answer:
2y² + y - 15
Step-by-step explanation:
ConceptsMultiplying Binomials:To multiply binomials, it's best to use the FOIL method, which stands for First, Outside, Inside, and Last. Let's analyze the first, outside, inside, and last term in the binomial we're given by bolding them (in addition, the numbers we bolded are the numbers we multiply; i.e. for the first term, we multiply y and 2y):
First: (y + 3)(2y - 5)Outside: (y + 3)(2y - 5)Inside: (y + 3)(2y - 5)Last: (y + 3)(2y - 5) SolvingSolving the BinomialStep 1: Apply FOIL method.
[tex](y)(2y) + (y)(-5) + (3)(2y) + (3)(-5)[/tex] [tex]2y^2 -5y +6y -15[/tex]Step 2: Simplify.
[tex](2y^2)+ (-5y+6y)+(-15)[/tex] [tex]2y^2+y-15[/tex]Therefore, the answer is 2y² + y - 15.
Answer:2[tex]y^{2}[/tex]+y-15
Step-by-step explanation:
(using distributive property)
(y+3)(2y-5)
y(2y-5)+3(2y-5)
2y^2-5y+6y-15
2y^2+y-15
The ice skating rink charges an hourly fee for skating and $3 to rent skates for the day. Gillian rented skates and skated for 3 hours and was charged $21. Which equation represents the cost, c(x), of ice skating as a function of x, the number of hours of skating?
c(x) = 3x + 3
c(x) = 6x + 3
c(x) = 7x + 3
c(x) = 8x + 3
Answer:
c(x) = 6x + 3
Step-by-step explanation:
c(x) = 6x + 3
he skated for 3 hrs and was charged $21
c(3) = 6(3) + c(3) = 18 + 3
c(3) = 21
correct....so it is c(x) = 6x + 3
p.s please mark this question as brainleist
Thx
answer:
B) c(x) = 6x + 3
explanation:
Gillian rented skates, which costs $3. Now you must subtract that from your total as the next step is to find how much the hourly fee for skating is. $21 - $3 = $18. $18 was the total price for three hours of skating so to find how much the hourly rate is, you divide it by 3. $18/3 = 6. Therefore it is $6 per x amount of hour(s) plus $3 for skates, or simply put, c(x) = 6x +3.

Abby is collecting rainfall data. She finds that one value of the data set is a high-value outlier. Which statement must be true?
Abby will use a different formula for calculating the standard deviation.
The outlier will increase the standard deviation of the data set.
The spread of the graph of the data will not change.
Abby will not use the mean when calculating the standard deviation.
When Abby finds that one value of the data set is a high-value outlier, the true statement is B. The outlier will increase the standard deviation of the data set.
What is an outlier?It should be noted that an outlier simply means a number in a data set that is further out from the other numbers.
In this case, when Abby finds that one value of the data set is a high-value outlier, the true statement is that the outlier will increase the standard deviation of the data set.

Tell wether the angles are complementary or supplementary. Then find the value of X
Answer:
The angles are Complementary Angles.
x = 55°
Step-by-step explanation:
the angles are Complementary Angles, because when added, together they form a 90° angle.
•to find the value of x, we form the equation :
⇒90° = x° + (x - 20)°
⇒90 = x + x - 20
⇒90 = 2x - 20
•shifting the 2x to the left side and the 90 to the right side
⇒2x = 90 + 20
⇒2x = 110
•shifting the 2 to the right side
⇒x = 110/2
⇒x = 55° Answer...
