Step-by-step explanation:
(sketch to understand)
use SOH/CAH/TOA rules to solve
sin rule is used
solve for x
(working in the picture attached)
The Algebraic equations (x - 20)² and x² - 20 have an equal value My number is 6.
<h3>What is an Algebra equation?</h3>
Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
I think of a number, if I subtract 10 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result.
Let the number be x.
If I subtract 20 from my number that is x - 20 then square the result that is (x-20)².
And if I square my number that is x² then subtract 20 from the result that is x² - 20.
Both the result are the same then we have
(x - 20)² = x² - 20
x² - 20x + 100 = x² - 20
-20x + 100 = -20
x = 6
My number is 6

Answer:
E. 64%
Step-by-step explanation:
The table above is a two-way frequency table which consists of two variables - job status of students and their car ownership.
The columns of the table shows whether job status of the students, whether they have a job or not, while the rows shows us whether the student has a car or not.
From the table, the cell that has 94, tells us the total number of students that were surveyed.
The number of students that have a car is represented by the first row = 38 + 22 = 60 students.
% of students in the survey who have a car = no. of students who have a car ÷ total number of students surveyed × 100%
= 60/94 × 100 = 63.8 ≈ 64%.
