Answer:
A, B, C
Step-by-step explanation:
The total number of students is the sum of the students taken each course. Hence the total number of students is:
Total number = 6 + 10 + 18 + 4 + 12 = 50 students
A) The percentage of students offering chemistry = (number of students offering chemistry / total number of students) * 100%
percentage of students offering chemistry = (10 / 50) * 100% = 20%
Option A is correct
B) number of students taking health science = 12, while number of students taking physics = 6. Hence About twice as many students are taking Health Science than are taking Physics.
Option B is correct.
C) The percentage of students taking physic = (6 / 50) * 100% = 12%
Therefore for 150 students, the number of students taking Physics = 12% * 150 = 0.12 * 150 = 18
Option C is correct
D) The percentage of students taking earth science = (4 / 50) * 100% = 8%
Therefore for 25 students, the number of students taking earth science = 8% * 25 = 0.08 * 25 = 2
For every 150 students we could predict that 18 of the students are taking Physics.
Option D is correct
Answer: The slope is 12 pounds per day.
Step-by-step explanation:
They consumed 60 pounds on food in 5 days.
The slope or rate at which they consummed the in a day can be calculated as the amount of pounds consumed in the lapse of time, this is:
slope = 60pounds/5days = 12 pounds per day.
Answer:
your answer is 1500 because if you divide $15000 by 100 then you get 1500
Step-by-step explanation:
$15000/100 = 1500
Answer:
Option B
Step-by-step explanation:
A unit circle means radius of the circle = 1 unit
Let a terminal point on the circle is (x, y) and angle between the point P and x-axis is θ.
Center of the circle is origin (0, 0).
Therefore, ordered pair representing the terminal point will be (OP×Cosθ, OP×Sinθ) = 
OP.Cosθ = 1×Cosθ = 
Cosθ =
θ =
,
where n = integers
Similarly, OP×Sinθ = 1×Sinθ = -
Sinθ = -
θ =
,
where n = integer
Common value of θ will be, θ = 
Option B will be the answer.
