Answer:
Step-by-step explanation:
y = kx
400 = kr . . . . . . (1)
also, r = 4k . . . .(2)
400 = k(4k) = 4k^2
k^2 = 400/4 = 100
k = sqrt(100) = 10
The answer would be 40/63 as simplified.
Hope this helps! Can i have brainiest?
Answer:
A. Continuous, B. Discrete, C. Continuous, D. Continuous, E. Continuous.
Step-by-step explanation:
A. Area is a continuous unit. Then, the floor area of a kitchen is a continuous random variable.
B. Quantity is a discrete unit. Then, the number of bacteria in a particular cubic centimeter of drinking water is a discrete random variable.
C. The money amount is a continuous unit. Then, the dollar amount of the change in my pocket is a continuous random variable.
D. The pressure is a continuous unit. Then, the barometric pressure at a given location is a continuous random variable.
E. Time is a continuous unit. Then, the difference in reaction time to the same stimulus before and after training is a continuous random variable.
1/2r+2(3/4r-1)=1/4r+6
2r-2=1/4r+6
2r=1/4r+8
7/4r=8
7r=32
r=32/7
