Answer: The number of balloons varies directly with the number of tables. The two variables are directly proportional. The relationship of balloons to tables is the ratio 5:1, where 5 is the constant of variation. Use the equation y = kx, where k is the constant of variation resulting in the equation y = 5x.

Answer:
x = 12
Step-by-step explanation:
If Mary spent $45 altogether,
then she bought lunch for $9
so our equation now is
$45 = $9 + 3x
It is 3x because he bought 3 shirts and we used x because we didnt
now how much the price of those shirts were
$45 = $9 +3x
$45 - $9 = 3x
$45 - $9 = $36
$36 = 3x
$36 / 3 = 12
x = 12

Addends are any of the numbers added together in an equation.
The only time their grouping would matter would be if there were parentheses used to alter the normal Order of Operations.
For ex:
2 - (8 + 3) here, the 8 and 3 have to be grouped together before doing the subtraction.
Any addition problem without parentheses can be used for one where the grouping doesn't matter

Answer with explanation:</h2>
A. For males, Third quartile =14, First quartile = 3 (approx)
IQR = Third quartile - First quartile
= 14-3 = 11
B. For males, Median = 12
For females, Median = 17
The difference between the median values = 17-12=5
C. The mean would be a better measure of center for females because the data has no outliers.
The median would be a better measure of center for males because the data has outliers.
D. Reason for outlier: A large number of males gone for movie which is extreme value for the remaining values.
Answer:
SY=34, SK=21 and KY=13
Step-by-step explanation:
we have that
SY=SK+KY
substitute the given values
(36-x)=(13x-5)+(2x+9)
solve for x
36-x=15x+4
15x+x=36-4
16x=32
x=2
<em>Find the value of SY</em>
SY=(36-x)=36-2=34
<em>Find the value of SK</em>
SK=(13x-5)=13(2)-5=21
<em>Find the value of KY</em>
KY=(2x+9)=2(2)+9=13
