$0.30x=y should be the answer because there is a 30cent fee for every day and x represents how many days it's kept therefore you would add 30 cents for every day it's kept so it's valid to say $0.30x=y becaue the 30 cents times the total of days it's kept = y (the toatl)
I believe the answer is 2
Two complementary angles add up to 90 degrees. Hence, the problem can be set up and solved. Let x represents one angle and 5x represent the angle that is 5 times greater:x + 5x = 90 (simplify)6x = 90 (next divide both sides by 6 to find the value of x [the smaller angle])x = 15 (this is the smaller angle, next subtract 15 from 90 to find the greater angle)90 - 15 = 75 (this is the greater angle which is 5 times that of its complement) <span>90 take away 73...</span>
Answer:
b. continuous random variable
Step-by-step explanation:
Speed is a common continuous variable and the value is always random.
It is continuous because there is always another speed value between two speed values. For example, a car travelling at the rate of 50 mils per hour will either increase or decrease its speed at a continuous rate. No speed can drop suddenly form 50mph to 20mph.
It is random because although there might be speed limit, the speed recorded by the Highway patrol officer willl always be random in value.
