$-266
You have to do: 8 tickets× $32= $256
Then you add ten. $256+ $10= $266
So the debt for all the tickets and the fee, you put a negative sign. $-266
And that's how you get the answer $-266
Answer:
Step-by-step explanation:
The number of seats in the first row= 8
Total number of seats in the classroom=
The probability of the first student who enters the classroom will be assigned a seat in front row is given by:-
Therefore, the probability of the first student who enters the classroom will be assigned a seat in front row is .
Answer:
20%
0.5
Step-by-step explanation:
There are 20 margins, so you have to count how many are 6.0 or higher. There are 4 margins that fit this so you divide the 4 margins by 20, then multiply the quotient by 100. That's how you get 20%.
The most common time was 0.5.
Answer:
t - 22
Step-by-step explanation:
the difference means subtraction so t - 22 is your answer
By applying Pythagorean theorem, we have proven that the point (-1/2, -√3/2) lies on the unit circle.
<h3>How to prove this point lies on the unit circle?</h3>
In Trigonometry, an angle with a magnitude of -120° is found in the third quarter and as such, both x and y would be negative. Also, we would calculate the reference angle for θ in third quarter as follows:
Reference angle = 180 - θ
Reference angle = 180 - 120
Reference angle = 60°.
For the coordinates, we have:
sin(-120) = -sin(60) = -1/2.
cos(-120) = -cos(60) = -√3/2.
By applying Pythagorean theorem, we have:
z² = x² + y²
z = √((-1/2)² + (-√3/2)²)
z = √(1/4 + 3/4)
z = √1
z = 1.
