Answer:
DF = 2
Step-by-step explanation:
Formula for degree of freedom is;
DF = n - 1
Where n is sample size
In this question, political party affiliation could be Republican, Democrat, or Other. Thus, sample size is 3.
DF = 3 - 1
DF = 2
Thus, degree of freedom value would be 2
Y= 3.4. If you divide 37.4 by 11 then y would equal 3.4. Check by multiplying 3.4 by 11
Answer:
The first deal is better because it has more balloons for not too much of a price (individually)
Step-by-step explanation:
15*4= 60
60/18= 3.33
Deal 1= 3.33 for each balloon
10*5= 50
50/16=3.125
The initial term of this geometric series is 4, and the common ratio is -1/2. The sum is given by

The sum is

Answer:
the total area is 15.6 square units
Step-by-step explanation:
hello,
you can find the total area dividing the shape into two known shapes
total area= area of the trapezoid +area of the semicircle
then
step one
find the area of the isosceles trapezoid using

where
a is the smaller base
b is the bigger base
h is theheight
A is the area
let
a=2
b=5
h=4
put the values into the equation

Step two
find the area of the semicircle
the area of a circle is given by

but, we need the area of half circle, we need divide this by 2

now the diameter of the semicircle is 2, put this value into the equation

find the total area
total area= area of the trapezoid +area of the semicircle

so, the total area is 15.6 square units
Have a good day.
