The density of a fish tank is 0.5 fish over feet cubed . There are 30 fish in the tank. What is the volume of the tank? (1 point
1 answer:
The correct option is :
<u><em>Explanation</em></u>
Suppose, the volume of the fish tank is ft³
The density of the fish tank is 0.5 fish/ft³. It means, <u>the number of fish in 1 ft³ volume is 0.5</u>
So, the number of fish in ft³ volume will be:
Given that, there are 30 fish in the tank. So, the equation will be......
Thus, the volume of the tank is 60 ft³

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:
a) There is suggestive evidence the velvet leaf seed is successful at weed control.
b) Lower bound: 3.699 Upper bound: 6.629
c) Since the confidence interval contains the average percent of seeds to be infected by the beetle (5.164), so we fail to reject the null hypothesis at the specified level of significance.
Step-by-step explanation:
