Answer:
The blue liquid is toxic
Step-by-step explanation:
From the calculations I have done and attached to this problem
Null hypothesis:
H0 : p1 <= p2
Alternate hypothesis:
H1 : p1 > p2
^p1 = 0.925
^p2 = 0.2250
^P = (x1 + x2)/(n1+n2)
= 0.575
After calculating, I got test statistics = 6.33 ( check attachment)
P(z > 6.33) = 0.0000
In conclusion, our pvalue has been found to be less than the level of significance 0.05 so we reject null hypothesis and accept that we have enough sample evidence that the blue liquid is more toxic in comparison to white one.
Please check attachment for calculated test statistics.
Answer: How do you find the rate of change of volume?
The rate of change in volume is dV/dt. The question is asking for the rate that the side length is changing. That would be ds/dt. If we take the derivative of both sides of V = s^3 with respect to time, we get dV/dt = d/dt[s^3].
Answer:
B and E
Step-by-step explanation:
In the function f(m)= -50m+300
-50 is the gradient meaning it is the rate of change per month. This means that the rate of change is -50 since this is the coefficient of m.
Also, -50m must be negative since m represents a month and you cant have negative months, so you know that the amount of money is decreasing
Answer:
1. Slope = 1
2. Slope = 3
3. Slope = -2
4. Slope = 2
Step-by-step explanation:
Okay so when we are finding the slope of two points we use the slope formula
