Answer:
50 %
Step-by-step explanation:
From the diagram attached,
Percentage of total students that like watching television = [(WnR)/μ]×100......... Equation 1
The number of students that like watching television and reading (WnR) = 70
The total number of students (μ) = 40+20+70+10
The total number of students (μ) = 140
Substitute these values into equation 1
Percentage of total students that like watching television = (70/140)×100
Percentage of total students that like watching television = 1/2(100)
Percentage of total students that like watching television = 50 %
Answer:
C
Step-by-step explanation:
the answer is C because √8 can be rewrite as 8^1/2
A is wrong because 8 is another number
B is wrong because 4 is not the square root of 8
D is wrong because 8^2 = 64
the independent variable is the $6 you make at your job.
The dependent variable is how much you make each week. and the dependent variable represents x.
a reasonable domain for the function is going to have to be your $6 dollars because your pay rate doesn't go up or down.
a reasonable range for the function is 240 because you are only allowed to work 40 hours a week at any job unless they want to give you overtime so the max amount you can earn is $240
the function represents you working 20 hours and getting paid $120 because 6 times 20 is 120

Answer:
$2,070,000
Step-by-step explanation:
The series of salaries has a first term of $40,000 and a common difference of $2,000. The sum of them is given by the formula ...
Sn = (2a1 +d(n -1))(n/2)
where a1 is the first term of the series, d is the common difference, and n is the number of terms.
In this problem, we have ...
a1 = 40,000; d = 2,000; n = 30
so the sum is ...
S30 = (2(40,000) +2,000(30 -1))(30/2) = (80,000 +58,000)(15)
S30 = 2,070,000
The teacher will earn $2,070,000 over 30 years on this salary schedule.
