Answer:
Probability that a randomly selected student plays sport and is in band = 1/50
Step-by-step explanation:
Total number of students= 1900
Percentage of those that play sport and are in band = 2%
Hence those that play sport and are in band = 2/100 x 1900 = 38 students
Probability that a randomly selected student plays sport and is in band = 38/1900 = 1/50
Answer:
225
Step-by-step explanation:
if it is 1/3 off, then it means it's at 2/3 the price. now, you have to divide 450/2 to get the answer. 2/3 divided by 2=1/3
450/2=225, and thats how much money you will save
For this case we have the following equation:
h = -16t ^ (2) + 30t + 6
We substitute the value of h = 10 in the equation:
10 = -16t ^ (2) + 30t + 6
Rewriting we have:
0 = -16t ^ (2) + 30t + 6-10
0 = - 16t ^ (2) + 30t - 4
We look for the roots of the polynomial:
t1 = 0.144463904
t2 = 1.730536096
"the ball passes its maximum height, it comes down and then goes into the hoop". Therefore, the correct root is:
t = 1.730536096
Answer:
It goes into the hoop after:
t = 1.73 seconds
Will recommend to keep in touch with picture as name of angles are based on it!
So as you can see BA is parallel to DC as the arrow signs are made on it. And the figure has four sides , therefore we get to know that the above picture is of parallelogram.
How ?
As we know it's a parallelogram, so there's one property of parallelogram that opposite sides of Angle are equal.
Now Let's find value of y.
How ?
As we know it's a parallelogram, so there's one property of parallelogram that opposite sides of Angle are equal.
angles on same line
- 65 + 60 + z = 180°
- 125° + z = 180°
- z = 180° - 125 °
- z = 55°
At last :-
x = 65°
y = 65°
z = 55°
Answer:
x = (-1,-3) y = (5, -1)
Step-by-step explanation:
there's your equation.
