Answer:
m=-4/9
Step-by-step explanation:
Hope this helps ❤
9 = 1 + 8x - 8
9 = 8x - 7
9 + 7 = 8x
16 = 8x
16/8 = x
2 = x <==

Answer:
We conclude that the machine is under filling the bags.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 436.0 gram
Sample mean, = 429.0 grams
Sample size, n = 40
Alpha, α = 0.05
Population standard deviation, σ = 23.0 grams
First, we design the null and the alternate hypothesis
We use one-tailed(left) z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, we conclude that the machine is under filling the bags.
Answer:
Step-by-step explanation:
Rate at which gas is escaping, dV/dt = 14 ft³/hr
Volume, V = 400 ft³
Volume of a sphere, ................(1)
Differentiate both sides with respect to t
........................................(2)
From equation (1)
Substitute the value of r and dV/dt into equation (2)
