y² = 8y - 15 (alternate angles are equal)
y² - 8y + 15 = 0
(y - 5)(y - 3) = 0
y = 5 or 3
x + 8y - 15 = 180 (angles in a straight line add up to 180)
when y = 5
x + 40 - 15 = 180
x = 155°
when y = 3
x + 24 - 15 = 180
x = 171°
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.
Answer: 14.29 or rounded up to 15%
Step-by-step explanation:
525 - 450 = 75
You need at least $75 off the price to have enough money.
75/525 = x/100
Solve for X
75 * 100 = 7500
7500/525 = 14.2857143
If answer should be a whole percentage you would need the discount to be 15% in order to not fall short on funds.
A odd number lie between 0 and 11(0 and 11 not included), it means that total of ten numbers, starting from {1,2,3........,10} form our sample space.
sample space=s={1,2,3....,10}=total 10 numbers
So,
m=total no. of odd numbers{1,3,5,7,9} in our sample space=5 numbers
probability that number is odd=p=m/s
p=5/10=0.5
