b. 613 people
c. Categorical
Step-by-step explanation:
a. View attachment below
b.
Given
Total Number of People Surveyed = 1021
X tax return by professional / Number of People Surveyed = 60%
X tax /1021 = 0.6
X tax = 0.6 * 1021
X tax = 612.6
X tax = 613------ Approximated
So, the number of people used an accountant or professional tax preparer are 613.
c.
The data for preparing a tax return will be considered as categorical as the methods for a person to file his/her tax returns are categorized into four which are:
1.Electronically
2.Manual preparation
3.Online tax service
4.Use of software tax program
Answer:
i think probably 80°
Step-by-step explanation:
PQ = RS
2x+3 = 4x-3
x = 3
PTQ = RTS
9y-3x-1 = 5x+7y-5
2y-8x = -4
y-4x = -2
y-4(3) = -2
y-12 = -2
y = -2+12
y = 10
so PTQ = 9y-3x-1
9(10)-3(3)-1
90-9-1
80°
Answer:
2kx+4y=20 ⇒ kx+2y=10
3x+6y=30 ⇒ x+2y= 10
k is the coefficient of x, so it is the slope of the line
- when k=1, both equations will be same, then there are many solutions
- when k=0 there is one solution
- when k is anything different, then the lines will be parallel, so no solutions
