Answer:
Formula for area of triangle:
A = bh x 1/2
Formula for area of parallelogram:
A = bh
Now find the area of the figure above which is a triangle:
3(base) x 8(height) x 1/2 = <em>12</em>
Let's find the area of the parallelogram;
6(height) x 9(base) = <em>54</em>
Add the two areas together:
12 + 54 = 66 cm2

What in mathematics is a linear equation?
- A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
- Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
50 × 24% = 12
50 × 14%= 7
12+ 7 = 19
50+75 = 125
19 ÷125= 15.2%

Answer:
Step-by-step explanation:
We are given the following information in the question:
"Citizens less than 18 years old are not allowed to vote"
We define a variable x such that x represents the age of citizens.
We have to write a relationship with the help of an inequality for the ages of citizens who are not allowed to vote.
Citizens less than 18 are not allowed to vote.
So x should be less than 18.
This can be written as:
is the required inequality for the ages of citizens who are not allowed to vote.
Answer:
critical value is 4.41
Step-by-step explanation:
Given data
n = 10
α = .05
to find out
the critical value
solution
first we calculate degree of freedom i.e
degree of freedom = n -1
degree of freedom = 10 - 1
degree of freedom = 9
and
degree of freedom 2 =( n -1 ) 2
degree of freedom 2 =( 10 -1 ) 2
degree of freedom 2 = 18
so for degree of freedom 9 and degree of freedom 2 is 18 and α = .05
critical value is 4.41
