Answer:
Bike alone = 39
Step-by-step explanation:
Given that:
Total number = n(T) = 100
Jog= n(J)
Bike = n(B)
Bike and jog = n(BnJ) = 21
Number who jog = 46
Jog alone = 46 - 21 = 25
Neither jog nor bike = 15
Let bike alone = x
Hence,
Jog alone + bike alone + jog and bike + none of the two = 100
25 + x + 21 + 15 = 100
x = 39

Answer:
2.5
Step-by-step explanation:
The average rate of the function f(x) from x=a to x=b is given by:
From the question, the exponential function goes through (0,30) and (20,80).
This implies that f(0)=30 and f(20)=80
Therefore the average rate of change from x = 0 to x = 20 is
The second choice is correct
Answer:
As I answered your question, answer is D
Step-by-step explanation:
Move 4x to the other side
2y=10+4x
Divide both sides by 2y
Y=5+4x
2. X-y=13
Move the first variable to the other side
-y=13+x
